The three conditions differed only in one aspect: regarding the type of instruction presented to the participant in the beginning of Phase 1. In Condition I, a minimal instruction was presented; in Condition II a corresponding instruction was presented; and in Condition III a discrepant instruction was presented. In Phase 2, un-signalized changes in the programmed contingencies of reinforcement occurred. The task was to click with a computer mouse on one of two stimuli presented simultaneously. The results generally showed that in Condition I most of the participants presented discriminated performance in Phases 1 and 2, looking more frequently towards S- and at the irrelevant property of the stimulus by the end of the phase. In Condition II, all participants presented a discriminated performance, according to the what was specified in the corresponding instruction, since the beginning of Phase 1 and looked more frequently to S+, having most participants looked more frequently at the relevant part of the stimulus for discrimination. In Phase 2, most participants did not present performance under contingency control, looking with similar frequency rates towards S+ and S-, presenting different response patterns when stimulus parts were analyzed. In Condition III, most of the participants abandoned discrepant rule-following, presented in the beginning of Phase 1, and emitted discriminative performances according to the programmed contingencies in Phases 1 and 2. Most of the participants stared more frequently towards S+ and at the relevant property for discrimination by the end of the phases. The data of the three conditions indicate that instructions can interfere in eye movement patterns, as contingencies do, but generating different choice response and eye movement patterns.porAcesso AbertoMovimento dos olhosDiscriminação (Psicologia)Discriminação simplesInstruçõesDissertaçãoCNPQ::CIENCIAS HUMANAS::PSICOLOGIA::PSICOLOGIA EXPERIMENTAL
