The Effects Of A Reinforcer On Behavior Maintained By A Second External Reinforcer, Jeanne Marie Lamere

Masters Theses

A number of studies has shown that providing extrinsic rewards for performing an "intrinsically interesting" task decreases an individual's subsequent interest in that task when the rewards are no longer available (e.g., Deci, 1971, 1972; Lepper, Greene, & Nisbett, 1973). Based on these results, many have argued that extrinsic rewards decrease an individual's "intrinsic motivation." A fundamental premise of this argument is that "extrinsic" and "intrinsic motivation" are functionally different, a distinction that is not supported by a behavioral analysis. This study examined whether similar subsequent decrements in task performance would be observed when a behavior is maintained by one …

Generalization Of Promise-Do Correspondence Training With Respect To The Individual To Whom The Promise Is Made, Robert J. Latka

Masters Theses

This study used 3 subjects of normal (non-impaired) intelligence, 1 female and 2 males, between the ages of 10 and 13 years to study generalization of promise-do correspondence training effects. In a replicated AE design, contingent monetary reinforcers were used to establish promise-do correspondence in playing nonpreferred computer games. This study demonstrated that the effects of correspondence training procedures could be generalized to an alternative listener or individual to whom the promise was made. Generalization was less evident when there was no listener present. This study also provided some evidence that effects of promise-do correspondence training may not generalize to …

Research And Theory On The Housing And Care Of Laboratory Pigeons And Rats, Dylan David Schmorrow

Masters Theses

This study was an experimental analysis of: (a) housing preference of laboratory pigeons and, (b) the effects of housing on laboratory rat health. Pigeon preference between containment cages and fly cages was determined on the basis of exit time from the containment cage to the fly cage. Rat health was determined by the departmental veterinarian. The rats were exposed to traditional and alternative methods of housing.

The findings from this study indicate that (a) on the basis of pigeons' preferences concerning size, it may be more appropriate to house pigeons in fly cages; and (b) alternative methods of care and …
