This research is designed to evaluate the role of motivating operations on the rate of skill acquisition. Little research has been done on whether or not faster learning occurs when a reinforcer has been isolated for teaching a specific skill. The purpose of the current study is to determine whether deprivation of a preferred item will increase the rate of acquisition when compared to the acquisition rate when an individual has free access to a reinforcer. Preliminary results demonstrated that relative states of deprivation were associated with faster acquisition of simple discriminations. Preliminary findings resented at BABAT 2015.
