Eye movements along the establishment of functional stimuli classes
Nicolau K. Pergher, Edson M. Huziwara, Gerson Y. Tomanari

TL;DR
This study examines how eye movements change as people learn and adapt to visual stimuli during tasks involving reinforcement reversals.
Contribution
The study reveals new insights into how observing responses to stimuli shift during the formation and reversal of functional stimulus classes.
Findings
Participants showed longer observing responses to S– than to S+ stimuli.
Observing responses to all stimuli in a functional class changed immediately after a reversal in one stimulus.
Eye movement patterns provide insight into the dynamics of discriminative stimulus control.
Abstract
The present study analyzed the eye movement patterns of five typically developed adults who were exposed to a series of simple discrimination training tasks with reversals in the contingencies of reinforcement that led to the formation of functional stimulus classes. Two studies were planned. In Study 1, two visual stimuli were used to carry out one training phase and three consecutive reversals. In Study 2, the phases were repeated but four‐stimuli functional classes were established. In the second study, the selective observing responses to stimuli of functional classes following the reversal of the first stimulus were analyzed. The results showed shifts in the duration of observing responses as the discriminative functions of the stimuli were established and reversed. Unlike the existing literature, our study reveals that some participants maintain longer observing responses to S–…
