Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann
Effects Of Altering Motivation In Pigeons Performing A Titrating-Delayed-Matching-To-Sample Task, Zachary J. Zimmermann
Masters Theses
In order to better understand the role motivating operations (MOs) serve in preceding and evoking behavior, it is useful to examine the effects of whether manipulating motivation can influence performance on tasks with known behavioral outcomes. It is well established that altered stimulus control is responsible for changes in responding on tasks of generalization and discrimination. Therefore, if stimulus control could be influenced by MOs, then perhaps stimulus discriminations could be improved by manipulating the relevant MO. To this end, the effects of altering motivation via food deprivation were examined in pigeons using a titrating-delayed-matching-to-sample task. Additional pharmacological variables (i.e., …
Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell
Relative Reward Effects On Operant Behavior: Incentive Contrast,Induction And Variety Effects, Howard Cromwell
Howard Casey Cromwell
Comparing different rewards automatically produces dynamic relative outcome effects on behavior. Eachnew outcome exposure is to an updated version evaluated relative to alternatives. Relative reward effectsinclude incentive contrast, positive induction and variety effects. The present study utilized a novelbehavioral design to examine relative reward effects on a chain of operant behavior using auditory cues.Incentive contrast is the most often examined effect and focuses on increases or decreases in behavioralperformance after value upshifts (positive) or downshifts (negative) relative to another outcome. Weexamined the impact of comparing two reward outcomes in a repeated measures design with three ses-sions: a single outcome and …
