The key to the upliftment of the Adivasi community is a deep understanding of their culture, psychological resources and cognitive strengths. Ecology, Culture and Human Development: Lessons for Adivasi Education presents a comparative analysis of the cultural and cognitive dimensions of various communities in Canada, Ghana, China and India, and seeks answers from this analysis for Adivasi education. It debunks the myths of low intelligence and inferior cognitive capacity of the Adivasi community, and emphasizes the remarkable performance of Adivasi children when assessed in terms of their ecological and cultural contexts. Extensively illustrated and containing substantive data on all relevant aspects of human development, this book is a much-desired addition to the literature on this crucial aspect of social development in India. It is a comprehensive resource that aims to contribute substantially towards mitigating the travails of the Adivasi community and ensuring their social empowerment.

This book offers a comparative analysis of value and identity changes in several post-Communist countries. In light of the tremendous economic, social and political changes in former communist states, the authors compare the values, attitudes and identities of different generations and cultural groups. Based on extensive empirical data, using quantitative and qualitative methods to study complex social identities, this book examines how intergenerational value and identity changes are linked to socio-economic and political development. Topics include the rise of nationalist sentiments, identity formation of ethnic and religious groups and minorities, youth identity formation and intergenerational value conflicts

The general trend in Afghanistan is clear-cut: the overall security situation has consistently deteriorated since 2009, worsening dramatically since 2014. However, in the provinces of Afghanistan adjacent to Central Asia, the security situation has deteriorated even further than in Afghanistan as a whole. This report considers the range of options available to the Central Asian neighbors of Afghanistan (Tajikistan, Turkmenistan, and Uzbekistan) in responding to this growing threat, both unilaterally and in their bilateral engagement with actors in Afghanistan. Furthermore, it considers how decisionmaking processes in Central Asia will be affected by future developments in Afghanistan by assessing options and likely outcomes under a set of security scenarios in Afghanistan itself.

In culturally diverse societies, one of the biggest questions on our minds is 'how shall we all live together?' Mutual Intercultural Relations offers an answer to this fundamental and topical issue. By exploring intercultural relationships between dominant/national and non-dominant/ethnic populations in seventeen societies around the world, the authors are each able to chart the respective views of those populations and generate 'universal' principles of intercultural relations. The research reported in this book is guided by three psychological hypotheses which are evaluated by empirical research. It was also carried out comparatively in order to gain knowledge about intercultural relations that may be general and not limited to a few social and political contexts. Understanding these general principles will offer help in the development of public policies and programmes designed to improve the quality of intercultural relations in culturally diverse societies around the world.

This textbook on Instructional Design for Learning is a must for all education and teaching students and specialists. It provides a comprehensive overview about the theoretical foundations of the various models of Instructional Design and Technology from its very beginning to the most recent approaches. It elaborates Instructional Design (ID) as a science of educational planning. The book expands on this general understanding of ID and presents an up-to-date perspective on the theories and models for the creation of detailed and precise blueprints for effective instruction. It integrates different theoretical aspects and practical approaches, such as conceptual ID models, technology-based ID, and research-based ID. In doing so, this book takes a multi-perspective view on the questions that are central for professional ID: How to analyze the relevant characteristics of the learner and the environment? How to create precise goals and adequate instruments of assessment? How to design classroom and technology-supported learning environments? How to ensure effective teaching and learning by employing formative and summative evaluation? Furthermore, this book presents empirical findings on the processes that enable effective instructional designing. Finally, this book demonstrates two different fields of application by addressing ID for teaching and learning at secondary schools and colleges, as well as for higher education.

This report presents the results of an ESRC-funded research project that examined the behavioural and attitudinal impacts of the English plastic bag charge that was introduced in October 2015. The project used a mixed-methods longitudinal approach, and included a national survey, a diary-interview study, and supermarket observation study. Overall, the research has shown that the English plastic bag charge has made a strong and positive impact on people’s behaviours and attitudes. The research found that the charge was eff ective at breaking old habits, and that it became more popular as people adapted to the policy. Evidence was also found that the charge increased environmental awareness and the acceptability of other environmental policies. The success of the plastic bag charge in eff ectively changing plastic bag use and increasing support for other charges to reduce waste suggests that similar policies could also be successfully implemented, such as a deposit return scheme on plastic bottles or a charge on disposable coff ee cups.

Background and aims. This research reported here presents findings from an evaluation of the development and implementation of the Healthy Community Challenge Fund (otherwise known as the ‘Healthy Towns’ programme). A key aim of the research has been to inform the development of future environmental and systems‐based ‘whole town’ approaches to obesity prevention. The overall aim of the Healthy Towns programme was to pilot and stimulate novel ‘whole town’ approaches that tackle the ‘obesogenic’ environment in order to reduce obesity, with a particular focus on improving diet and increasing physical activity. Through a competitive tender process, nine towns were selected that represented urban areas across England ranging from small market towns to areas of large cities. The fund provided £30 million over the period 2008‐2011, divided amongst the nine towns. The amounts awarded ranged from £900,000 to £4.85 million. Towns were instructed to be innovative and were given freedom to develop a locally‐specific programme of interventions. This report supplements local process and impact evaluations undertaken by each town (not reported here) by taking an overall view of the programme’s development and implementation. Our evaluation therefore addressed the following research questions: 1. What kinds of interventions were delivered across the Healthy Towns programme? 2. Were environmental and infrastructural interventions equitably delivered? 3. How was the Healthy Towns programme theorised and translated into practice? 4. How was evidence used in the selection and design of interventions? 5. What are the barriers and facilitators to the implementation of a systems approach to obesity prevention?

Crisis is a burning issue; this is not a phenomenon, which can be conquered forever. Current approach to crisis is an optimized collaboration, which allows for manageable, measurable and predictable software development. Crisis is a new reality to live and work with. The current software development crisis dates back to the 1960s. The root cause of crisis is misbalance between resources and options. Understanding the nature of crisis helps to understand the reasons for the future crises.

This book is a navigator in lifecycle models, methodologies, principles and practices for predictable and efficient software development in crisis, i.e. under rapid requirement changes, resource deficit and other uncertainties. Therefore, the starting chapters suggest the major approaches to software development and their applicability in crisis. Further narration is case-based; it involves large-scale software implementations in different industries and knowledge transfer processes in IT education. The book suggests a set of principles that potentially marry the client’s and the developer’s views of the future software product in order to avoid or to mitigate the crisis.

The book will be helpful for students, postdocs, theorists and practitioners in software development. It suggests approved principles and practices of crisis management for software development.

The aging of the Russian population and the rapid shrinking of its labor force in coming decades will make the human capital each worker contributes increasingly vital for sustaining economic output and growth. While improvements in general education are necessary to build the foundation for a productive future labor force, a broad-based and effective system of adult education can provide second-chance opportunities for current workers to enhance their productivity and lengthen their working lives and for low-skilled immigrants to be integrated into the workforce. How well the Russian Federation addresses these multiple needs at and beyond the workplace will depend on how effective its adult education system is. This study targeting policymakers outlines the problems of Russia's growing skills gap, especially the shortage of higher-order cognitive and socio-emotional skills, and examines the current state of adult education.

The phenomenon of self-disclosure can be considered at different levels of scientific exploration being approached either from the socio-psychological viewpoint or from the individually determined personal perspective, where the subject of openness may serve as an individual with his personal potential in the field of social communications, and social groups or corporations as well. At the level of communicative dialogue and interpersonal relationships self-disclosure is manifestation of human potential capabilities and his readiness for open and trusting cooperation in society. In practical terms, handling these issues can be referred to as a social order from the part of the representatives of those professions where comfortable social communication appears to be an important factor of communicative competence and professionalism of the person.

The book describes consequnces of culture in Russia.

The work was implemented as part of the Federal Dedicated Programme “Fostering Scientific and Academic Staff for Innovative Russia” for 2009-2013.

The first part of this book is devoted to the old problem of fundamental motivations that can hardly be approached in another way, other than theoretically. The second part of the book is devoted to new or rather marginal concepts that seem capable to enrich general models of motivational processes. Part three of the book deals with the issues of self-regulation and self-determination; in the last two decades the problems of motivation can be hardly dealt with without touching these issues. The focus of the last part of the book is cultural context and cultural mediation of motivation. This book was planned not as a collection of discoveries to be considered, but rather as a collection of nontrivial views that may turn helpful for making a better sense of the discoveries actually made.

The authors of the papers from Croatia, Italy, Mexico, Poland, Romania, and Russia look for constructive ways of contributing to harmonic development of the personality in modern information society. The common feature of the papers is that they either relate to the new scientific discipline called Cognitonics or correspond to its goals.    Cognitonics emerged in the first half of the 2000s. It   aims (a) at explicating the distortions in the perception of the world caused by the information and communication technologies and globalization and (b) at coping with these distortions in different fields by means of elaborating systemic solutions for compensating the negative implications of the kind for the personality and society, in particular, for creating cognitive-cultural preconditions of the harmonic development of the personality in the information society and for ensuring the successful development of national cultures and national languages.

Purpose

The purpose of this paper is to explore the psychological adjustment process of expatriates from Chinese multinational enterprises, including how their social capital affects this process.

Design/methodology/approach

This qualitative investigation was based on semi-structured, in-depth interviews with 26 Chinese expatriates. The grounded theory method was applied to guide the data collection and analysis.

Findings

The psychological adjustment process of Chinese expatriates includes three periods: crisis, self-adjustment and self-growth period. In addition, bonding capital (including organizational, family and co-cultural colleagues’ support) is more conducive to Chinese expatriates’ psychological well-being than bridging capital (e.g. host-nationals’ support). Finally, a separation acculturation strategy is more conducive to psychological adjustment, rather than an integration strategy.

Research limitations/implications

This study focused on expatriates themselves. Future research should consider other stakeholders (e.g. organizations, family), and examine expatriate adjustment from new perspectives (e.g. strategic human resource management, work-family balance). This study had a small sample and focused on only one organization. Future research could usefully add other Chinese multinational corporations, and other Chinese expatriates to expand the generalizability of the current findings.

Practical implications

This study suggests the possible benefits of management practices for expatriates. Organizations can develop an “expatriate bubble” to help structure basic life overseas. Organizations could develop family-support programs and make them expatriate-supportive. Organizations should also strengthen the connections between expatriates and local colleagues.

Originality/value

Few scholars have elaborated on how different support groups (based on their cultural backgrounds) influence the psychological adjustment of expatriates. Until now, mainland Chinese expatriates have received little attention. In addition, this research takes a significant step forward by illuminating the psychological adjustment of Chinese expatriates from a social capital perspective.

Plastic bags create large amounts of waste and cause lasting environmental problems when inappropriately discarded. In 2015, England introduced a mandatory five pence (US$0.06/€0.06) charge to customers for each single-use plastic bag taken from large stores. Combining a longitudinal survey (n=1,230), supermarket observations (n=3,762), and a longitudinal interview study (n=43), we investigated people’s behavioural and attitudinal responses to the charge. We show that all age, gender, and income groups in England substantially reduced their plastic bag usage within one month after the charge was introduced, with interviewees highlighting the ease of taking their own bags. Support for the bag charge also increased among all key demographic groups. Increased support for the plastic bag charge in turn predicted greater support for other charges to reduce plastic waste, suggesting a ‘policy spillover’ effect. Results indicate a broad and positive effect of the bag charge, which appears to have catalysed wider waste awareness among the British public. This may facilitate the introduction of other policies to eliminate avoidable single-use plastics and packaging.

In a questionnaire study with N = 1730 participants, aged from 11 to 72 years (M = 20.4, Me = 19, SD = 6,96), 60% females, we developed the Relevance of the Home Environment Questionnaire (RHEQ) aimed at measuring parameters of the home environment as inhabitants’ eco-social resource. Results from exploratory and confirmatory factor analyses showed that the seven-factor structure of the questionnaire was uniquely identified. The scales were titled as follows: Privacy, Potential, Self-presentation, Ergonomics, Home detachment, Plasticity, and Historicity. Consistency coefficients (Cronbach’s alpha) of scales ranged from .91 to .94. Age trends in four out of seven scales were found. Potential scores were higher in women, while Home detachment - in men. Content validity was investigated by comparison of home relevance scores in students living in their own homes or dormitories. Convergent validity was explored by measuring correlations of the scales with the Functionality of the Home Environment Questionnaire and the Home Attachment Scale. All psychometric properties are satisfactory. Data was discussed with regard to the possible applications in research, expertise, and psychotherapy.

Environmental identity is a self-concept that incorporates and is defined by a relationship with nature; it is useful for predicting relevant social attitudes and behavior. In the current paper, the concept is investigated in three empirical studies using the Environmental Identity (EID) scale. Study 1 (n = 222) was devoted to validating the Russian version of the EID scale. Along with the EID scale, we measured environmental attitudes with the New Environmental Paradigm and Global Awareness of Consequences scales. Results showed that, in line with the original version, the Russian version has a one-factor structure and good internal consistency (α = .88), and is positively connected with environmental concern, global awareness of consequences, egoistic, altruistic and biospheric values. Study 2 (n = 94) investigated the connection between EID and attitudes toward the plant world using the People and Plants questionnaire. EID predicted all variables describing people’s attitudes towards plants: Joy, Aesthetics, Experience of interaction with plants, Closeness to nature, and Ecology. Finally, Study 3 (n = 200) examined the connection between EID and empathy with nature and people. Dispositional Empathy with Nature and Interpersonal Reactivity Index scales were used. It was revealed that EID was positively connected and contributed to both types of empathy, more strongly impacting empathy with nature. It is concluded that the Russian version of the EID scale is a valid and reliable instrument. In addition, the EID concept seems to relate to a more general ability to connect with things external to oneself. As such, it has the potential to be helpful in forming psychotherapeutic programs and in designing restorative environments.

The article presents pilot data from a study conducted as part of a large project investigating the impact of socialization on child development supported by a Grant from the Government of the Russian Federation (№14.Z50.31.0027, PI: Grigorenko). The purpose of the study was to investigate indicators of psychological, social and emotional well-being in adults with experience of institutionalization in comparison with peers who grew up in biological families. We used scales from the Achenbach System of Empirically Based Assessment (ASEBA) and the World Health Organization Quality of Life Questionnaire (WHOQOL-BREF). Results showed no significant differences between the group of orphanage graduates and the comparison group. However, using classification procedures we established that living conditions (separate apartment vs. a "public" space - a communal apartment or a dormitory) is an important variable predicting group belonging based on well-being indices. Thus, it appears that in adulthood, it is not the history of institutionalization but the actual living environment that is associated with indicators of the psychological, social and emotional well-being of orphanage graduates.

The perception of a pair of contours in a retinal image cannot be understood simply by adding up the perceptions of the individual contours, especially when they form a perpendicular junction, or are parallel to one another. It is the relationship among the contours that determines what is perceived. Note that it is hard to actually compare the perception of such configurations quantitatively. We managed to do this by testing the perception of such configurations in three psychophysical experiments in which the perception was characterized by measuring the orientation threshold of a single contour. This threshold was estimated by using a modified Method of Constant Stimulibased on the assumption that contours forming a configuration are perceived individually, and that they are integrated linearly. This assumption made the quantitative comparison of the perceived configurations possible. We found that changes of the estimated threshold depended on the type of the configuration, specifically thresholds estimated from a perpendicular junction were substantially lower than thresholds estimated from a single contour or from a non-perpendicular junction. The lowest thresholds were observed when the threshold was estimated from a pair of parallel contours. These results suggest that the visual system is sensitive to perpendicular junctions and parallel contours in a retinal image.

Abstract

OBJECTIVE:

The Oxford Cognitive Screen (OCS) is a screening tool for the assessment of poststroke deficits in attention, memory, praxis, language, and number processing. The goal of the present study was to develop a Russian version of the OCS (Rus-OCS) via translation of the original battery, its cultural and linguistic adaptations, and reporting preliminary findings on its psychometric properties.

METHOD:

All parts of OCS were translated by native Russian-speaking neuropsychologists. Russian-speaking stroke patients (N = 205) were assessed with the Rus-OCS. Their performance was compared with performance of 60 healthy Russian-speaking adults aged between the ages of 18 and 91 years. The performance of 15 stroke patients and 42 healthy adults were assessed with a parallel version within 7 days of first testing. Convergent validity of the Rus-OCS was established via correlations with comparable tasks. Performance of three stroke groups with different lesion lateralization (right, left, and bilateral) was compared on language and visual attention subtasks. Preliminary normative data based on 5th to 95th percentile were also reported.

RESULTS:

Measures of internal consistency and test-retest reliability ranged from acceptable to very good and estimates of convergent validity ranged from moderate to high. Sensitivity and specificity was found to range from .56 to 1 and from .73 to 1, respectively. Significant differences in performance between stroke and healthy groups on all subtasks confirmed the discriminative power of the Rus-OCS was good.

CONCLUSIONS:

Rus-OCS is a promising cognitive screening instrument for Russian-speaking patients. However, further validation is needed. Constraints of socioeconomic differences between Russian speakers in the wider population should be considered. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

Attempts to estimate the contribution made by motor activity to insight problem solving is hindered by a lack of detailed description of motor behavior. The goal of this study was to develop and put to the test a novel method for studying the dynamics of insight problem solving based on a quantitative analysis of ongoing motor activity. As a proper task model, we chose the nine-dot problem (Maier, 1930), in which solvers had to draw a sequence of connected line segments. Instead of using the traditional pen-and-paper way of solving the nine-dot problem we asked participants to use their index finger to draw line segments on the surface of a tablet computer. We are arguing that successful studying of the role of motor activity during problem solving requires the distinction between its instrumental and functional role. We considered the functional role on the motor activity as closely related to the on-line mode of motor planning.

The goal of Experiment 1 was to explore the potential power of the method and, at the same time, to assay the patterns of motor activity related to on-line and off-line modes of motor planning. Experiments 2 and 3 were designed to uncover the potential impact of preliminary motor training on the motor output of successful and unsuccessful problem solvers. In these experiments, we tested hypotheses on how preliminary motor training, which presumably played a functional role in Experiment 2 and an instrumental role in Experiment 3, affects the motor activity of a problem solver and hence their effectiveness in solving the problem.

The three experiments showed consistent results. They suggest that successful solving of the nine-dot problem relies upon the functional role of motor activity and requires both off-line and on-line modes of motor planning, with the latter helping to overcome the perceptual constraints imposed by a spatial arrangement of the nine dots. The method that we applied allows for systematic comparison between successful and unsuccessful problem solvers based on the quantitative parameters of their motor activity. Through it, we found new specific patterns of motor activity that differentiate successful and unsuccessful solvers.

Whether the motor cortex activation accompanying concrete verbs comprehension is necessary for verbs conceptual processing is still a hotly debated topic in the literature. Answering this question, we examined to what extent the more difficult access to verb semantics requires an additional engagement of cortical motor system in verb generation task. Using power suppression of MEG beta oscillations (15-30 Hz) as an index of sensorimotor activation, we presented to our participants the noun cues which either were strongly associated with a single verb and prompted the fast and effortless verb retrieval, or were weakly associated with multiple verbs and were more difficult to respond to. A whole-brain analysis of beta suppression revealed that the only cortical regions sensitive to the difficulty of semantic access were the higher order motor areas on the medial and lateral surfaces of the frontal lobe. This differential activation of cortical motor system accompanied effortful verb retrieval and preceded the preparation of vocal response for more than 500 milliseconds. Since the mid-frontal frontal brain areas are involved in maintaining abstract representations of actions during their initiating and planning, we argue that our finding supports the view that motor associations contribute to retrieval of verb semantics.

This paper investigates the characteristics of the affective component in the structural mere exposure effect (SMEE). Two approaches are considered – fluency attribution approach (FA) and affect as predictive efficiency approach (APE) – within a predictive coding framework. Using the artificial grammar learning and affective priming paradigms, we demonstrate that a violation of implicitly learned regularities elicits an automatic negative affective response. This result suggests that SMEE can be observed without any overtly evaluative judgment. Participants’ decisions on the grammaticality of stimuli did not change this pattern. We conclude that SMEE is based on the affective response to prediction errors made by the cognitive system and may include the fluency attribution process in the later stages of processing.

Expectations of people with high and low intelligence differ considerably. High intelligence is associated with several desirable social outcomes, while low intelligence is associated with low social status and poverty. We assumed that attributing high intelligence to a person could lead to a more positive evaluation of them and, as a result, less negative attitudes toward them. In the experimental study (N = 781) we investigated how levels of perceived intelligence impact the long-term stigmatization of dirty workers. The results show that perceived high intelligence of dirty workers decreases long-term stigmatization towards them, but these findings relate only to people performing moral dirty work. Implicit theories about intelligence were controlled as a covariate and had no significant effect. Results are discussed in terms of the positive effect of perceived high intelligence on everyday perception. Limitations and future directions are also discussed.

The human factor is always decisive in social development. The role of active behavior and above all economic behavior is obvious. However, there are some difficulties: the law regulates predominantly "external" behavior; psychology covers interests, motives, will, emotions.   This paper analyzes individuals’ interests and motives in economics. Coherence and contradictions of the labor interests are investigated on the basis of a survey made in several organizations. The rank of interests (economic, professional, career, group, corporate, territorial, and common civil) in the dependence of labor group type (shareholders, top managers, line managers, employees) is formed.  

This study tests the psychometrics of a Russian version of the Couple Motivation Questionnaire (CMQ), and analyzes the possible distinctions between the Russian and English versions of the instrument. We hypothesize that the adopted version of CMQ repeats the original structure, and a continuum of motivation in romantic relationships will be found as a result of the correlation analysis. We conducted a correlation study on an online sample of (N = 497) using CMQ, the Test of Existential Motivations in Interpersonal Relationships, the Dyadic Adjustment Scale and the Codependency Scale. The theoretical model, which was proposed in the original study (Blais et al., 1990), linked self-determination theory's motivational styles to adaptive relationship behaviors and the general quality of romantic relationships. The model was successfully confirmed for the Russian sample using a reverse translation and the psychometric testing of CMQ. The model revealed resistance to cultural influences, and the new instrument is suggested for studies of the motivational aspects of relationships using Russian samples.

According to the scientific literature on writing, poetry and prose have their own distinct characteristics. We suppose, therefore, that the value-motivational basis for being creatively active is specific and different for poetry and prose writers. On the basis of existing studies on individual values, motivation types and creative behavior, we build hypotheses about their interrelations, specifying the differences between poetry and prose writing. The research was an empirical correlational study using questionnaires for data gathering: the revised PVQ-R of Schwartz, the authors’ questionnaire to measure frequency of creative behavior and a questionnaire on the motivation of creative behavior developed on the basis of Deci and Ryan's CBI questionnaire. The sample includes 240 representatives of “little creativity”, those involved in the non-professional writing of poetry or prose during the previous year (2016). The results show that poets and prose writers have differences in values and their relations to specific creative behavior in micro-domains of literary creativity. We also found a positive relationship between specific motivation types and the main creative behavior. We identified the mediating role of autonomous motivation between values and creativity in the poets’ group. This research demonstrates that there is sense in the division of creativity into domains and micro-domains as there are differences in the values and motivation types related to creative activities in micro-domains. 

Recent geopolitical changes in Crimea initiated the process of massive identity transformation among ethnic majority and minority groups. Current study was aimed at examining the role of multiple identities and acculturation strategies in the psychological well-being of Crimean Tatar minority (N=80). The study revealed high motivation for ethno-cultural continuity among Crimean Tatars. The combination of ethnic, religious and place identities positively predicts both life-satisfaction and self-esteem. These combined identities also positively predict integration strategy and negatively assimilation strategy. Combined national and Russian ethno-linguistic identitiy positively predicts integration and assimilation strategies and negatively predicts separation strategy. The findings indicate the importance of taking historical, political, social context into account in the studies on minority issues.

This research investigates the relation of personality metatraits and negotiation styles, and the role of negotiation self-efficacy in it. This study was interviewed of Russians with negotiation background at the extractive industry (N=119). Participants were given Thomas-Kilmann questionnaire, CPM-Q personality questionnaire and negotiation self-efficacy questionnaire. It was found that some personality metatraits are significant and direct predictors of negotiation styles and, additionally, negotiation self-efficacy. Nevertheless, negotiation self-efficacy does not mediate the influence of personality metatraits on negotiation styles.

The leaky integrate and fire model of neural spiking has been used extensively to simulate saccadic responses in a variety of tasks from visual search to simple reaction times. Although it has been tested for its neural spiking accuracy and its spatial prediction of fixations in visual salience, it has not been well tested for its temporal accuracy. Saccade generation invariably results in a positively skewed distribution of saccadic reaction times over large numbers of samples, yet we show that the LIF algorithm tends to produce a distribution shifted to shorter fixations (in comparison with human data) in its classic implementation. Further, parameter optimization using a genetic algorithm and Nelder–Mead method does improve the fit of the resulting distribution, but is still unable to match temporal distributions of human responses in a simple visual search task. Further analysis revealed, that the LIF algorithm produces discrete reaction times instead of distributions. Aggregated over many pictures they may be treated as a distribution although the form of this distribution depends on the input images used to create it.

Approximately twenty years ago, Laurent Itti and Christof Koch created a model of saliency in visual attention in an attempt to recreate the work of biological pyramidal neurons by mimicking neurons with centre-surround receptive fields. The Saliency Model has launched many studies that contributed to the understanding of layers of vision and the sphere of visual attention. The aim of the current study is to improve this model by using an artificial neural network that generates saccades similar to how humans make saccadic eye movements. The proposed model uses a Leaky Integrate-and-Fire layer for temporal predictions, and replaces parallel feature maps with a deep learning neural network in order to create a generative model that is precise for both spatial and temporal predictions. Our deep neural network was able to predict eye movements based on unsupervised learning from raw image input, as well as supervised learning from fixation maps retrieved during an eye-tracking experiment conducted with 35 participants at later stages in order to train a 2D softmax layer. The results imply that it is possible to match the spatial and temporal distributions of the model to spatial and temporal human distributions.

Cognitive dissonance arises as a reaction to conflict appearing in choices between two equally attractive options. It leads to changes in the desirability of these options. The chosen option becomes more desirable whereas the rejected option is devalued. Despite cognitive dissonance being largely used by social psychologists to explain social conformity and preference reevaluation, little is known about the neural mechanisms of such choice-induced preference changes. In this study, we modulated the activity of the posterior medial frontal cortex (pMFC), which has been found to be involved in cognitive dissonance in neuroimaging studies. We influenced the activity of the pMFC before individual choices using both cathodal and anodal transcranial Direct Current Stimulation (tDCS) during a revised version of Brehm's free-choice paradigm. Our results showed that cathodal tDCS over the pMFC significantly decreased the typical choice-induced preference change relative to a sham stimulation. On the contrary, no significant effect of anodal tDCS was observed. Our findings of the influence cathodal tDCS on preference re-evaluation highlight the central contribution of the pMFC in cognitive dissonance and provide evidence that pMFC plays a key role in the implementation of subsequent post-decision preference change.

This is a theoretical study. Theoretical understanding of a visual stimulus in a psychophysical experiment is critical for controlling the experiment and for interpreting its results. This fact encourages vision scientists to use “simple” visual stimuli. A triangle in a 3D scene is one of the simplest stimuli for studying 3D perception. In this study, we analyzed geometrical properties of a relation between the triangle and its retinal image using a computer algorithm. Based on the analysis, we discuss validity of results of past studies that used triangles as their visual stimuli.

This is an empirical study. The perception of a pair of contours in a retinal image cannot be understood simply by adding up the perceptions of the individual contours, especially when they form a perpendicular junction, or are parallel to one another. It is the relationship among the contours that determines what is perceived. Note that it is hard to actually compare the perception of such configurations quantitatively. We managed to do this by testing the perception of such configurations in three psychophysical experiments in which the perception was characterized by measuring the orientation threshold of a single contour. This threshold was estimated by using a modified Method of Constant Stimuli based on the assumption that contours forming a configuration are perceived individually, and that they are integrated linearly. This assumption made the quantitative comparison of the perceived configurations possible. We found that changes of the estimated threshold depended on the type of the configuration, specifically thresholds estimated from a perpendicular junction were substantially lower than thresholds estimated from a single contour or from a non-perpendicular junction. The lowest thresholds were observed when the threshold was estimated from a pair of parallel contours. These results suggest that the visual system is sensitive to perpendicular junctions and parallel contours in a retinal image.

The temporal dynamic characteristics of mood play an important role in various aspects of our lives including our psychological health and well-being. It is assumed that the individuals with high emotional intelligence (EI) are characterized by more positive and stable moods. However, most studies analyze how EI is related to emotional traits or momentary assessments of mood; there are almost no findings on EI relationships with mood dynamics. The present study fills this gap. Two research questions were asked. How mood dynamics characteristics are related to each other and to what extent are they independent? Which aspects of EI are related to particular characteristics of mood dynamics? Method. To collect data on mood dynamics, an experience sampling procedure was implemented. Twenty-six female participants reported their mood for two weeks, three times a day, using the EmoS-18 questionnaire. Their emotional intelligence was measured with the EmIn questionnaire. Mean mood scores calculated across all measurement points were regarded as static characteristics showing a mood background typical for the participant. Also, three dynamic characteristics of mood were calculated, namely variability, instability, and inertia. Results. Mood variability and instability were found to be very closely related to each other, measuring essentially the same construct. Inertia is relatively independent. EI was not related to mean mood scores which contradicts the results of other studies and can be explained by the use of the experience sampling procedure. EI was positively related to the inertia of a positive mood with high arousal and a negative mood with low arousal. In addition, a negative relationship between EI and the instability of tension was found. Most of the correlations were low. Further studies with higher statistical power are needed for more decisive conclusions. However, the results show that experience sampling provides new important insights on the role of EI in mood

The well-known modern dimensional models of affect include two or three dimensions. They are typically based on self-reports using English emotion terms. It remains unclear to what extent these models can be applied to different cultures and languages. The present study is aimed at finding the dimensions underlying the descriptions of emotional states in Russian and suggests a structural model of affect based on these findings. At the first stage, a comprehensive list of Russian nouns denoting emotional states was compiled. It comprised 330 words and was reduced to a list of 56 words. At the second stage, participants rated their emotional states using this list. The exploratory factor analysis yielded three dimensions that underlay participant descriptions of the emotional states – negative affect with low activation, positive affect with high activation, and tension. This model is compared to other structural models of affect and its special features are discussed. This model can be used for developing Russian-based measures for the assessment of mood.

Attending a location in space facilitates responses to targets at that location when the time between cue and target is short.  Certain types of exogenous cues – such as sudden peripheral onsets – have been described as reflexive and automatic.  Recent studies however, have been showing many cases where exogenous cues are less automatic than previously believed and do not always result in facilitation.  Given a lack of the behavioral facilitation, we propose to test whether this also suggests a lack of underlying attention to that location.  We test exogenous cueing with saccadic responses at a range of cue-target onset asynchronies (CTOAs), but also alternate measures linked to the allocation of attention such as saccadic curvature, microsaccades and pupil size.  As expected, we find no early facilitation at short CTOAs, and likewise no impact of the cue on microsaccade direction or pupil size.  We do observe a small dip in the frequency of microsaccades after the cue as well as a tendency for saccadic curvature away from the cued location at short CTOAs.  We interpret these results as evidence of reduced attention at the cued location that is removed or inhibited too quickly to be measured as facilitation of saccadic responses.

In this paper, a novel application of the event-related potential (ERP) method is proposed. The authors applied an N400 evoked potential for brand perception analysis, particularly for brand associations. Traditionally, N400 has been used as a marker of semantic incongruence of a word to a context. The N400 activity is manifested in a more negative deflection of ERP response to incongruent stimuli. We recorded N400 in response to congruent and incongruent sentence endings in marketing and non-marketing contexts, respectively. In the main experimental condition, congruent and incongruent brand associations (nouns) presented before brand names were selected from real marketing campaigns building brand communities. In the control semantic memory N400 condition, the incongruent sentence endings evoked significant fronto- centrally distributed N400 brain response at 300–500 ms. The N400 response in the brand association condition was delayed for 250 ms compared to incongruent words in the context of short sentences and appeared in the central brain area. In this study, we showed for the first time the possibility of applying the N400 method to identify the strength of brand associations using ecologically valid stimuli.
