Extreme temporal condition for visual identification task is held. A gaze-contingent eyetracking study was used to assess how presaccadic stimulus influences the one presented during a reactive saccade. A strong forward masking effect is found. Identification rate of second image is below chance, but still in accordance with previous studies, where no masking was present. Identification rate, erratic responses, statistical connection with alternative response (2AFC task), physical properties of saccades are similar to simple intrasaccadic identification task [3; 5]. Two aspects of transsaccadic visual perception were hypothesized, possessing common temporal structure: sensoric (geometric primitive detection) and gnostical (naturalistically valid object identification).

This research describes a method for studying the authenticity/unauthenticity of the information re- ported by people in video images. It is based on automatic tracking of coordinates of key points of a speaker’s face using OpenFace software. When processing the data, the multiple linear regression procedure is used. It was found that the dynamics of neighboring key points in the obtained models has a multidirectional char- acter, indicating the presence of a superposition of several dynamic structures, corresponding to the characteristic complex changes in the face position and facial expressions of the sitter. Their isolation is realized by means of the principal component analysis. It is shown, that the first 11 principal components describe 99.7% of the variability of the initial data. The correlation analysis between the number of credibility/confidence statements on the set of time intervals and the principal component loadings, allows to differentiate the dynamic structures of the face, connected with the assessments of credibility of the reported information. Automated analysis of face dynamics optimizes the process of collecting empirical data on the sitter’s appearance and their semantic structuring, as well as expands the range of predictors of the assessments of the truthfulness of the messages received.

The article is devoted to the results of approbation of the Geneva Emotion Recognition Test (GERT), a Swiss method for assessing dynamic emotional states, on Russian sample. Identification accuracy and the categorical fields’ structure of emotional expressions of a “living” face are analysed. Similarities and differences in the perception of affective groups of dynamic emotions in the Russian and Swiss samples are considered. A number of patterns of recognition of multi-modal expressions with changes in valence and arousal of emotions are described. Differences in the perception of dynamics and statics of emotional expressions are revealed. GERT method confirmed it’s high potential for solving a wide range of academic and applied problems.

The article provides a review of experimental studies of interpersonal perception on the material of static and dynamic facial expressions as a unique source of information about the person’s inner world. The focus is on the patterns of perception of a moving face, included in the processes of communication and joint activities (an alternative to the most commonly studied perception of static images of a person outside of a behavioral context). The review includes four interrelated topics: face statics and dynamics in the recognition of emotional expressions; specificity of perception of moving face expressions; multimodal integration of emotional cues; generation and perception of facial expressions in communication processes. The analysis identifies the most promising areas of research of face in motion. We show that the static and dynamic modes of facial perception complement each other, and describe the role of qualitative features of the facial expression dynamics in assessing the emotional state of a person. Facial expression is considered as part of a holistic multimodal manifestation of emotions. The importance of facial movements as an instrument of social interaction is emphasized.

The possibilities of obtaining information about the identity of a third party were studied in different ways of depicting a face. The results of two series of experiments were compared, in which the same configuration relations were included in the context of either a schematic face made up of abstract geometric figures or photographic portraits of specific people. Stimulus material was based on the figures of E. Brunswick (1956), demonstrating the dependence of induced expressions (joy/gust) on the spatial organization of the face. Assessment of individual psychological features of the sitter and self-assessment of observers were performed using the Personal Differential method. As a result of the analysis the general regularities of perception of a person in the created conditions are revealed: polarization of estimations of features and their asymmetry defined by impressions about the state of modelers — real or imaginary. Two nonspecific phenomena of interpersonal perception related to transformations of the configuration relations of the face have been revealed: (1) inversion of the attractiveness of the person shown in the photo, and (2) doubling of the personality of the virtual sitter. It is shown that the influence of the observer’s self-esteem on the modeler’s assessment depends both on the type of the face image and on the direction of configuration transformations. The obtained results are interpreted in terms of the dynamics of constellation of features, the mechanism of super generation of emotional manifestations and halo-effect of attractiveness. The methodology of general psychological research of interpersonal perception based on the variation of configuration relations of the face is substantiated.

A microstructural analysis of perception of a partner in communication was carried out. Mute video recordings of 15 clips of a structured conversation in which communicants expressed true and false judgments, were subjected to complex coding. In each 40 ms frame 51 nonverbal signs/102 binary markers indicating the state of the facial zones, the nature of the movements of the head, hands and body were considered. Based on expert estimates, the proportion of frames was calculated, in which each of the markers is present at selected time intervals. Looking at the video clips, 35 observers intuitively, by external features, determined the fragments when the communicator is telling truth and when lying. The frequency and time of occurrence of markers were analyzed. Frequency regression models of “true” and “false” response of communicants were built. It is shown that the required estimates are performed by the observer 1.5—2 seconds before the answer. High-frequency features form a stable core of the impression of the reliability of the communicator’s judgments, complemented with changeable low-frequency features explaining the growth of explanatory power of regression models. Markers have been identified that contribute to adequate perception of the reliability of information reported. The style of non-verbal behavior of people implementing alternative communication strategies is described.

A comparison of the parameters of oculomotor activity in the perception of static and dynamic images of the face was made. It is shown that in both static and dynamic conditions, the trajectory of eye movement is determined by the internal structure of the face of the and the functional connections of the facial areas of his face. Differences were found at the level of individual parameters of oculomotor activity: the duration of examination of the face zones, the duration of fixation and the amplitude of saccades. Routes for reviewing static images are fully cyclic in nature. Recurrent fixations in the same zone of interest are poorly expressed, and their contribution to the overall structure of movements is negligible. When perceiving dynamic images, the survey routes have a degenerate, partially reduced character, determined by the current dynamics of facial expressions; the contribution of repeated fixations in the same zone of interest increases.

We studied the perception of human facial emotional expressions during step-function stroboscopic presentation of changing mimics. Consecutive stages of each of the six basic facial expressions were pre sented to the participants: neutral face (300 ms) — expression of medium intensity (10—40 ms) — intense expression (30—120 ms) — expression of medium intensity (10—40 ms) — neutral face (100 ms). Alternative forced choice task was used to categorize the facial expressions. The results were compared to previous studies (Barabanschikov, Korolkova, Lobodinskaya, 2015; 2016), conducted using the same paradigm but with boxcar-function change of the expression: neutral face — intense expression — neutral face. We found that the dynamics of facial expression recognition, as well as errors and recognition time are almost identical in conditions of boxcar- and step-function presentation. One factor influencing the recognition rate is the proportion of presentation time of static (neutral) and changing (facial expression) aspects of the stimulus. In suboptimal conditions of facial expression perception (minimal presentation time of 10+30+10 ms and reduced intensity of expressions) we revealed stroboscopic sensibilization — a previously described phenomenon of enhanced recognition rate of low-attractive expressions (disgust, sadness, fear and anger), which has been previously found in conditions of boxcar-function presentation of expressions. We confirmed the similarity of influence of real and apparent motion on the recognition of basic facial emotional expressions.

We studied the formation of representations of children faces observed by adult subjects. Adult participants (aged between 18 and 22) evaluate tenseness and activity of the children aged from 3 to 6 years. We tested the hypothesis of interaction between the perceived individual psychological characteristics of a person and the features of his face. It was discovered that a child’s activity estimate is connected to his/her facial angle between eye pupils and the upper lip. Children with a smaller middle part of the face and smaller distance between eyes are assessed as being more tense that the rest of the sample group. Tense expressions on children’s faces are associated with some faint traces of fear and anger.
