Behind the scenes of Developmental Language Disorder: time to call neuropsychology back on stage
The distractive effects on attentional task performance in different paradigms are analyzed in this paper. I demonstrate how distractors may negatively affect (interference effect), positively (redundancy effect) or neutrally (null effect). Distractor effects described in literature are classified in accordance with their hypothetical source. The general rule of the theory is also introduced. It contains the formal prediction of the particular distractor effect, based on entropy and redundancy measures from the mathematical theory of communication (Shannon, 1948). Single- vs dual-process frameworks are considered for hypothetical mechanisms which underpin the distractor effects. Distractor profiles (DPs) are also introduced for the formalization and simple visualization of experimental data concerning the distractor effects. Typical shapes of DPs and their interpretations are discussed with examples from three frequently cited experiments. Finally, the paper introduces hierarchical hypothesis that states the level-fashion modulating interrelations between distractor effects of different classes.
The article concerns R. Wollheim’s theory of twofoldness, the one of the most acclaimed analytical theories of pictorial representation. Wohhleim has pointed to the structural distinction of seeing pictures from seeing objects and situations face-to-face, thus proposing the theory of seeing-in and twofoldness. This conception presupposes the split, simultaneous seeing of the picture’s object and material surface. Considering the basic influences, features and shortcomings of Wollheim’s theory, author specifies the question of to what extent the scope of this theory is limited to artistic pictures. Alongside with this theory’s reconstruction and critique, the article provides its interpretation based on spatially-oriented definitions of twofoldness (B. Nanay, J. Kulvicki) coupled with the actualization of the distinction between representational content of a picture and its figurative content. The first one includes all spatial relations that can be seen in it, the second one – all that can be seen in it and described by non-abstract concepts. Wollheim reframed to apply this distinction to his notion on twofoldness. But it gives the possibility to bring out the convincing definition of twofoldness as the simultaneous visual experience of pictorial surface (i.e., some material object in viewer’s egocentric space) and of representational content (i.e., semantically active spatial relations which one sees in the picture). This interpretation may be considered a useful instrument for non-reductionist description of pictorial experience and pictures’ ontological duality, hence it is devoid of Wollheim’s psychologism while maintaining his focus on visuality. Moreover, it provides some opportunities for applying Wollheim’s theory beyond the contexts of analytical philosophy of pictures, thus connecting it to the problems of phenomenological and hermeneutic theories of image.
It is well known, that even in optimal conditions animals and humans make spontaneous errors which are the most prominent manifestations of attention system failures. Our goal was to investigate the causes of attention system failures in normal state of arousal and without distracting objects. We have designed a new task which allows to answer the following question: which stage of sensory processing is compromised during attention lapses?
Recent events in Ukraine and Russia and the subsequent incorporation of Crimea into the Russian state, with the support of some circles of inhabitants of the peninsula, have shown that the desire of people to belong to the Western part of Europe should not automatically be assumed. Discussing different perceptions of the Ukrainian-Russian war in neighbouring countries, this book offers an analysis of the conflicts and issues connected with the shifting of the border regions of Russia and Ukraine to show how ’material’ and ’psychological’ borders are never completely stable ideas. The contributors – historians, sociologists, anthropologists and political scientists from across Europe – use an interdisciplinary and comparative approach to explore the different national and transnational perceptions of a possible future role for Russia.
The article proposes application of the level approach to attention research. Four basic principles of levelbased architecture of attention are derived from theoretical premises of the level approach to cognition and the psychology of attention as well as from empirical data. The author offers a variant of empirical research program which is based on the logic of the level approach. Finally the 5 level model of attention processes organization is proposed on the basis on experimental data. The article also contains examples of author's empirical studies which are interpreted in the level approach framework. The first study demonstrates the functioning of the redundancy principle (which is one the basic principles stated in study) in the visual inspection tasks. The second study shows the differences in the efficiency of memorizing the same material and the differences in experiencing of subjective confidence in mnemonic judgments depending on the leading level of attention in task solving.
Distractor's effect (stimulus which is irrelevant at a certain moment and ignored) on task solving efficiency is considered. It is revealed that according to problem situation and connection with target stimulus any distractor can produce two opposite effects: negative - interference and positive - redundancy effect. Distractor effects' classification based on one of possible grounds - distractor's source: sensory inputs effects, hierarchical effects and correlational effects is given. Possibility of level-hierarchical relation between the three classes of effects is discussed.
The results of research of different areas of personality of homeless men: values, life attitudes, activity, homelessness area is presents. The data indicate the presence of a number of characteristics inherent in varying degrees all homeless people. The data obtained can be used to build an effective program of psychological re-socialization of homeless people.
The present article continues the investigation of the Soqotri verbal system undertaken by the Russian-Soqotri fieldwork team. The article focuses on the so-called “weak” and “geminated” roots in the basic stem. The investigation is based on the analysis of full paradigms (perfect, imperfect and jussive) of more than 170 “weak” and “geminated” Soqotri verbs.
