Recognition of facial expressions in the proximal periphery of the visual field ¹¹²⁰

Experimental study of the communicative organization of visual space in micro intervals of time is the subject of this paper. During the experiment, images of basic expressions of male face in the form of undifferentiated presentation of eccentrically localized objects (0 ° – 10 °) in the left, right, top and bottom parts of the field of view were shown to the observer for 200 ms. The results of evaluation of the effectiveness of the modality of identification of facial expressions at different exposure conditions and registration of oculomotor activity of observers indicate that the area of effective perception of facial expressions goes beyond the central area of the visual field, covering a considerable part of the proximal periphery. Estimation of parameters of the zone with the most effective perception of facial expressions, which are reflected in the characteristics of targeted saccades, suggests that the internal structure of visual space is heterogeneous, and its value depends not only on the egocentric location of expression, but also on their modality. Micro dynamics of communicative visual space depends on the form of the oculomotor activity of observers.
