[The efficiency of recognition of the size of segments of line by the observers with different parameters of the cognitive style].

We estimated efficiency of recognition of the size of segments of line by the persons with different parameters of cognitive style: the field dependence--field independence, the analytically--synthetically style, the flexible--rigid cognitive control. The size of segments of line was judged in task of the magnitude of the Ponzo illusion measurements. It was established, that the magnitude of the Ponzo illusion significantly less in subjects with the field independence cognitive style, than with field independence. The persons with the flexible type of the cognitive control showed the tendency to more accurate perception of the size of the segments in the Ponzo figure, than with the rigid cognitive control. The rinteraction between the analytically--synthetically style of the categorization and the magnitude of the Ponzo illusion is not fixed.
