Session Duration And The Vi Response Function: With-In Session Prospective And Retrospective Efffects, James Dougan, Alfred Kuh, K. Vink Nov 1993

Session Duration And The Vi Response Function: With-In Session Prospective And Retrospective Efffects, James Dougan, Alfred Kuh, K. Vink

Scholarship

Two experiments examined the effects of session duration on responding during simple variable-interval schedules. In Experiment 1, rats were exposed to a series of simple variable-interval schedules differing in both session duration (10 min or 30 min) and scheduled reinforcement rate (7.5 s,15 s, 30 s, and 480 s). The functions relating response rate to reinforcement rate were predominantly monotonic for the short (10-min) sessions but were predominantly bitonic for the long (30-min) sessions, when data from the entire session were considered. Examination of responding within sessions suggested that differences in the whole-session data were produced by a combination of …
