Choice in a variable environment: effects of unequal reinforcer distributions

Article Abstract:

The quantification of steady-state choice in concurrent schedules is analyzed. The results extended previous research using the same basic procedure that had included only reinforcer distributions symmetrical around 1:1 and the analysis suggests that the variables controlling choice operated at a number of levels.

A theory of attending, remembering, and reinforcement in delayed matching to sample

Article Abstract:

A theory of attending, reinforcement, working memory in delayed matching to sample, and disruption of attending during retentional interval was tested. Results made different predictions of the effects of reinforcer probabilities and disruptors on forgetting functions in multiple schedules.
