An Attempt to Dissociate Effects of Response Requirements and Sample Duration in Conditional Discrimination Learning with Pigeons.

Description

Attempts to control various aspects of response requirements and sample viewing durations of sample stimuli show that an increase in both facilitates acquisition of conditional discriminations. Despite these attempts, few empirical data exist that demonstrate the relative contributions of both response- and time-dependent schedules. In addition, viewing opportunities of sample stimuli are present outside of the researchers' control, allowing for 'unauthorized sample viewing.' This study employed a titrating delay matching-to-sample procedure to systematically control various aspects of response requirements and sample viewing durations to independently assess their relative contributions towards conditional discrimination performance. Four pigeons worked on a titrating delay ... continued below

Description

Attempts to control various aspects of response requirements and sample viewing durations of sample stimuli show that an increase in both facilitates acquisition of conditional discriminations. Despite these attempts, few empirical data exist that demonstrate the relative contributions of both response- and time-dependent schedules. In addition, viewing opportunities of sample stimuli are present outside of the researchers' control, allowing for 'unauthorized sample viewing.' This study employed a titrating delay matching-to-sample procedure to systematically control various aspects of response requirements and sample viewing durations to independently assess their relative contributions towards conditional discrimination performance. Four pigeons worked on a titrating delay matching-to-sample procedure in which the delay between sample offset and comparison onset continuously adjusted as a function of the accuracy of the pigeons' choices. Results show sample viewing durations contribute most toward conditional discrimination performance. The data show 'unauthorized sample viewing' improved acquisition of conditional discriminations and should be a consideration in design of future research.
