The effects of three levels of food deprivation, and shift in reinforcement patterns were investigated in selectively bred high-(RHA/Lu) and low( RLA/Lu) avoidance strains. The high-avoidance strain responded to the ...

The effects of Variable Interval (VI) schedules of reinforcement on the dispersion patterns and aggregate densities of a small population of rats was studied. Eight male rats were permanently housed in an arena in which ...

In two separate experiments, an 8 rat 8 station operant arena was used to study resistance to extinction to test learning and optimal foraging theories of behaviour. The learning theory, called the generalized decrement ...

Experimental interest for the present research stemmed from the traditionally accepted notion that qualitatively different reinforcers, such as food and water, have similar effects on learning. The present investigation ...

Reinforced practice was used to treat children for fear of water. The primary measure of fear reduction was a behavioural task involving approach and entry to water. A comparison of pre-and post-test scores on the ...

The rationale for the study was to determine if music could be used as an effective reinforcer for increasing appropriate practice behaviors, and reduce problem behaviors in the competitive swimming environment. The ...

A group consisting of eight male Hooded rats was tested for risk-sensitive foraging preferences in an eight station operant arena, under conditions of open and closed economies. The group could choose to forage at either ...
