The ability to perceive biological motion (BM) and extract meaningful information from it represents a crucial prerequisite for developing social skills. Both autism spectrum disorders (ASD) and autistic traits in the general population are associated with social functioning impairments. This study examines BM perception in social and non-social contexts among adults with varying levels of ...

Relevance. Social cognition impairments in patients with schizophrenia complicate their interactions with others, adversely impacting daily functioning and the progression of the disease. Investigating these impairments is crucial for developing effective strategies for diagnosis, rehabilitation, and psychological intervention to improve patients’ quality of life.
Intention. To investigate the impairments in cognitive information processing in patients with ...

Convolutional Neural Networks (CNNs) match human performance in many visual tasks like the classification of images, however they may not simulate the underlying biological processes. We implemented a CNN to try replicate results from an object inversion experiment with Transcranial Magnetic Stimulation (TMS). After training on upright faces, the CNN model went through three stages ...

Developmental dyscalculia (DD) is a subtype of learning disabilities, which is characterized by lower mathematical skills despite average intelligence and average or satisfactory performance in other academic areas. It is not fully understood how such deficits emerge in the course of brain development. When considering the mechanisms of dyscalculia, two domain-specific systems are distinguished. The ...

Detecting 3D symmetry is important for the human visual system because many objects in our everyday life are 3D symmetrical. Many are 3D mirror-symmetrical and others are 3D rotational-symmetrical. But note that their retinal images are 2D symmetrical only in degenerate views. It has been suggested that a human observer can detect 3D mirror-symmetry even from ...

Background. Incidental findings are items of visual search that are potentially of significance, but were not the main object of the initial search. They have been previously widely discussed in the field of radiology. However, the underlying perceptual mechanisms of such phenomenon are still unclear.
Objective. The current study aims to examine incidental findings in different ...

The article is devoted to the study of the relationship between the individual values of the respondents and their psychosemantic assessment of the visual image (on the example of a photo-image of the architectural tiles of the Moscow Kremlin). In the study, we relied on the theory of values of S. Schwartz (Schwartz, 1992), the ...

The study analyzes the readability of visual identity in the context of the problem of multimodality and communicativeness, as well as its specific design, plastic and visual-graphic features on the example of city brand logos. As part of an empirical study, a survey of developers of visual identity was conducted, whose position reflects the principles ...

Yu, Todd, and Petrov (2021, Journal of Vision) and their follow-up study (Yu, Petrov, & Todd, 2021, i-Perception) aimed at evaluating the role of three-dimensional (3D) symmetry in binocular shape perception by comparing their experimental data to predictions they derived from our computational models. We point out in this note that their predictions were incorrect, ...

The visual system can recover 3D information from many different types of visual information, e.g., contour-drawings. How well can people navigate in a real dynamic environment with contour-drawings? This question was addressed by developing an AR-device that could show a contour-drawing of a real scene in an immersive manner and by conducting an observational field ...

In recent years, the principle predictive coding has become one of the frontiers in the contemporary cognitive science and is used to explain a growing range of cognitive functions, as well as emotions, social psychological effects, etc. Implementing the general concept of anticipation as the cornerstone of human activity, this principle echoes some ideas articulated ...

People can perceive 3D information from contour drawings and some types of configurations of contours in such drawings are important for 3D perception. We know that our visual system is sensitive to these configurations. Koshmanova & Sawada (2019, Vision Research, 154, 97–104) showed that the sensitivity is higher to a parallel configuration of contours than to ...

The review addresses the main directions of anticipation research in the contemporary
cognitive psychology and some related areas of application of the predictive coding principle as a
new general principle of human cognitive system and the brain functioning. The introduction of this
principle to human information processing models raised a new wave of interest towards the
feedback processing in ...

This book reports on theoretical and experimental research answering key questions in neuroscience, philosophy of mind, and cognitive research. It gives a special emphasis on findings achieved within the territory of the former U.S.S.R, which has remained largely unknown to an international readership. The volume gathers authoritative studies on cognitive development, consciousness, attention and perception. It covers research on ...

Human beings can perceive depth by using binocular disparity, namely the difference between a stereo-pair of retinal images. It is commonly believed that the visual system requires oculomotor information about the relative orientation between the two eyes to perceive depth on the basis of binocular disparity. Such oculomotor information can be obtained from the efference copy ...

Understanding the visual stimulus in a psychophysical experiment, theoretically, is critical for controlling the experiment, for interpreting the empirical results of the experiment, and for discussing the mechanisms the visual system used to get these results. This fact encourages visual scientists to use “simple” visual stimuli in their experiments. A triangle is one of the ...

Artists can represent a 3D object by using only contours in a 2D drawing. Prior studies have shown that people can use such drawings to perceive 3D shapes reliably, but it is not clear how useful this kind of contour information actually is in a real dynamical scene in which people interact with objects. To ...

An object is 3D centro-symmetrical if the object can be segmented into two halves and the relationship between them can be represented by a combination of reflection about a plane and a rotation through 180° about an axis that is normal to the plane. A 2D orthographic image of the 3D centro-symmetrical object is always ...
