We previously showed that people can discriminate multiple intermixed groups of objects based on "segmentability," large gaps between values in feature distributions forming several peaks. Here, we test whether such discrimination is based on local or global sampling. Two arrays of lines of various orientation (O) and length (L) were presented; both had identical feature ...

Although objects around us vary in a number of continuous dimensions (color, size, orientation, etc.), we tend to perceive the objects using more discrete, categorical descriptions. For example, in the variety of colors and shapes on a bush, we can see a set of berries and a set of leaves. Previously, we described how the ...

Ensemble summary statistics represent multiple objects on the high level of abstraction—that is, without representing individual features and ignoring spatial organization. This makes them especially useful for the rapid visual categorization of multiple objects of different types that are intermixed in space. Rapid categorization implies our ability to judge at one brief glance whether all ...

Wired to punish? Electroencephalographic study of the resting-state neuronal oscillations underlying third-party punishment
, , , Neuroscience 2021 Vol. 471 P. 1-10
For over a decade, neuroimaging and brain stimulation studies have investigated neural mechanisms of third-party punishment, a key instrument for social norms enforcement. However, the neural dynamics underlying these mechanisms are still unclear. Previous electroencephalographic studies on third-party punishment have shown that inter-brain connectivity is linked to punishment behavior. However, no clear evidence was provided ...

What helps us to form a new category? In this study we replicated effect of features nameability on learning of new artificial category (Zettersten & Lupyan, 2018): success of finding a visual categorical feature (e.g., color shade) among the different features (another color shades) with basic names was higher than among the features with less ...

At present, the effect of targeted memory reactivation during slow-wave sleep (SWS) on auditory recognition remains unexplored. We tested a possibility to improve recognition of difficult sounds after their presentation during SWS and the correlation of recognition with electrophysiological parameters of brain activity in two groups of healthy volunteers. For the main group of subjects, ...

Knowledge of target features can guide attention in many conjunction searches in a top-down manner. For example, in search of a red vertical line among blue vertical and red horizontal lines, observers can guide attention toward all red items and all vertical items. In typical conjunction searches, distractors often form perceptually vivid, categorical groups of ...

The subjects were distributed into one of two conditions based on the ratio of the semantics of the word and feedback: in the expected condition, with the correct ...

В последние десятилетия было проведено значительное количество исследований, показавших, что опыт институционализации и ранней психосоциальной депривации оказывает негативное влияние на развитие человека. Важным аспектом оценки развития является исследование функционального состояния головного мозга в состоянии покоя. Целью данной работы является выявление изменений распределения спектральной мощности ЭЭГ в состоянии покоя у детей раннего возраста, проживающих в домах ...

The goal of the present study was to investigate the interaction between different senses of polysemous nouns (metonymies and metaphors) and different meanings of homonyms using the method of event-related potentials (ERPs) and a priming paradigm. Participants read two-word phrases containing ambiguous words and made a sensicality judgment. Phrases with polysemes highlighted their literal sense ...

Feature binding in auditory modality requires attention as indexed by mismatch negativity and N2b in an active discrimination task
, , et al., NeuroReport 2018 Vol. 29 No. 4 P. 308-313
Currently there are two opposing views on feature binding in the auditory modality: according to behavioral studies, this process requires focused attention, while electrophysiological studies suggest that feature binding may be fully automatic and independent from attention. Here, we examined whether feature binding depends on higher-level attentional processes, by manipulating the attentional focus. We used ...

Subjects in an experimental study were asked to remember objects associated with artificial names. The pronunciation of object names led to decrease in the memory performance concerning specific qualities of objects; the same effect was not found for pronunciation of cues concerning object location. The authors discuss the role of words in perceptual categorization. ...

This research was focused on postdictive properties of apparent motion — an illusion of movement resulting from successive presentation of two dots. Obviously, the mechanisms of integration of two dots’ representations can take place only after the second dot is presented. There are two alternatives of what exactly happens. Firstly, a person becomes aware of ...

Our experimental study looked into the way existing knowledge influences the way subjects con- struct the rules of categorization and modify them as they are applied. We modified the experiment of E. Wisniewski and D. Medina (1994) by asking the respondents not only to create a categorization rule, but also to use it to categorize ...

В эксперименте испытуемые запоминали объекты в условиях, когда они были ранее названы или одним словом, или двумя. Как оказалось, наличие двух слов привело к ухудшению запоминания индивидуальных свойств предметов, в отличие от условия с одним словом. Такой эффект интенции значения - спонтанной активацией категоризации в присутствии слова – впервые обнаружен на искусственном материале. ...

The attunement of speech perception/discrimination to the properties of one’s native language is a crucial step in speech and language development at early ages. Studying these processes in young children with a history of institutionalization is of great interest, as being raised in institutional care (IC) may lead to lags in language development. The sample ...

The heterogeneity of our visual environment typically reduces the speed with which a singleton target can be found. Visual search theories explain this via nontarget similarities and dissimilarities that affect grouping, perceptual noise, etc. Here, we show that increasing the heterogeneity of a display can facilitate rather than inhibit visual search for size and orientation ...

The article analyzes the current empirical data concerning the impact of speech signs on infants' concept learning. We confirm that influence of speech on the processes of categorization in infants affects all the aspects of their conceptual thinking: generalization, differentiation, individuation and inductive inference. On the basis of this review we distinguish two opposite theoretical ...

We utilized the event-related potential (ERP) technique to study neural activity associated with different levels of working memory (WM) load during simultaneous interpretation (SI) of continuous prose. The amplitude of N1 and P1 components elicited by task-irrelevant tone probes was significantly modulated as a function of WM load but not the direction of interpretation. Furthermore, ...

The effect of conceptual flexibility involves inclusion of attributes that are irrelevant to the formed category in the concept and their further handling where required. The previous studies show that the conceptual flexibility effect arises while performing feature inference tasks and doesn’t arise while performing classification tasks. In the last case attention becomes too focused ...
