Arbitrary Eye Movement Strategies in Global-Local Processing Experiments

Perceptual organization is one of the most hotly debated issues in visual perception. Human adults, normal conditions, process global features faster than local details, effect that called “Global Precedence”. Research has shown as stimulus eccentricity gets more distant from fovea, perceptual decisions details become delayed. This even happens when gaze fixated on center field view and location manually adjusted. The present study aims to explore eye movement strategies point not restricted a particular fixation point. Fourteen participants were asked respond Matching Similarity Judgment tasks. data was recorded using EYELINKIITM, with sampling frequency 1000Hz. Global Precedence Effect (GPE) observed two Additionally, higher average “arbitrary eccentricity” trials compared trials. Arbitrary referred individuals unconsciously choose perceive stimuli. Furthermore, number fixations significantly greater From our findings, we speculate daily life can world globally peripheral vision always need movements only decide focus foveally selectively attending seems necessary.
