Effects of fixed ratio schedules of reinforcement on exercise by college students.

Response-contingent reinforcement was expected to increase the time spent riding a stationary exercise cycle by college women. A single-subject experimental design was used. Three college-age women rode a stationary cycle until they were either too tired ...

Marijuana effects on sensitivity to reinforcement in humans.

Under controlled laboratory conditions, eight adult subjects smoked placebo and three different potencies of marijuana cigarettes ranging in Delta(9) THC content. Immediately following smoking, subjects were exposed to a laboratory task that provided ...

Within-subject comparison of real and hypothetical money rewards in delay discounting.

A within-subject design, using human participants, compared delay discounting functions for real and hypothetical money rewards. Both real and hypothetical rewards were studied across a range that included $10 to $250. For 5 of the 6 participants, no ...

Possible amotivational effects following marijuana smoking under laboratory conditions.

Human participants earned money by responding on a progressive-ratio (PR) schedule (initial value $50) or received money without responding on a fixed-time (FT) schedule. During the session, participants could terminate the PR schedule and initiate an FT ...

The effects of interpolated reinforcement on resistance to extinction in children diagnosed with autism: a preliminary investigation.

Studies on the "interpolation of reinforcement" effect (IRE) suggest that switching from an intermittent (INT) to a continuous (CRF) reinforcement schedule may result in less resistance to extinction than if extinction had followed INT alone. The finding ...
