Visual search, a fundamental human activity, entails a series of eye movements that integrate both bottom-up and top-down information to make goal-driven decisions. This process engages executive functions such as attention, memory, and decision-making. Using computational models and a behavioral experiment, we address a key open question: to what degree are individuals conscious of their own computational processes? In this study, a total of 50 participants completed a visual search task within natural scenes, providing both objective responses (clicking on the target location) and subjective responses (encircling the perceived target area). We assessed the predictive capability of the Entropy-Limit Minimization model in terms of both gaze path prediction and human responses. Preliminary findings demonstrate the model’s proficiency in anticipating human behavior; however, certain limitations persist in fully capturing the underlying human actions.
