Linguistic Mediation of Perceptual Adjustment in University Students

Students from different areas of academic training (Psychology vs. Optometry) completed a task in which they had to locate a "lost moving target" in a simulated forest on a computer screen. The effects of three independent variables were assessed: a) the type of trajectory of the moving target (regular and irregular), b) the time elapsed since the loss of visual contact with the moving target (delays of 1, 4 and 6 seconds), and c) administration / non administration of verbal consequences for localization responses. Results indicated that accuracy in localization responses was higher on 1) regular trajectories, 2) shortest delays, 3) verbal consequences condition, and 4) Optometry students. Findings are discussed in terms of the parameters of the task. Contributions of the academic training of the participants are discussed as a linguistic scenario in which differential modes of the contact with the environment’s mediation are learned.
