Abstract

The article outlines the possibilities of extrafoveal analysis during a conceptual visual search, when the target stimulus represents a geometric concept with an unknown form. The previous works have shown that when the target and distractors are widely diverging, the very first saccade is headed towards the target or the answer is given without any saccades, suggesting that the target is recognized extrafoveally. Our experimental design and data analysis intend to reveal extrafoveal processing of visualized concepts while saccades planning. We made the stimuli harder varying two factors: the difficulty of the target shape and its similarity to the distractors to determine the limit of complexity when the stimulus becomes too complex to be processed extrafoveally. Twelve participants with normal or corrected-to-normal vision took part in Experiment 1 and eighteen in Experiment 2. Four images of stereometric shapes were spaced at an equal distance from the center. In the first experi...
