RESUMO

Six undergraduate students were exposed to two simple discrimination procedures each. Three learned a simultaneous discrimination, followed by its reversion; and then learned a successive discrimination, also followed by its reversion. The other three learned a successive discrimination, followed by its reversion; and then learned a simultaneous discrimination, also followed by its reversion. Each participant used, during all sessions, an eye-tracking device, which records video streamings with a cursor indicating the users eye fixation. That allowed to calculate the time intervals for events related to the participants eye fixations during the discrminations. Results show that all three participants who learned the simultaneous discrimination first exhibited strong evidence of select-control, and two of them also exhibited later strong evidence of rejectcontrol. Participants who learned the simultaneous discrimination after the successive discrimination exhibited strong evidence of reject-control since the beginning, and two of them did it even before showing evidence of select-control.
