Two conditioned taste aversion experiments with rats were conducted to establish if a target taste that had received a prior pairing with illness could be subject to second-order conditioning during extinction treatment in compound with a flavor that also received prior conditioning. In these experiments, the occurrence of second-order…

Animals recognize a taste cue as aversive when it has been associated with post-ingestive malaise; this associative learning is known as conditioned taste aversion (CTA). When an animal consumes a new taste and no negative consequences follow, it becomes recognized as a safe signal, leading to an increase in its consumption in subsequent…

Data are presented from two experiments investigating whether covert responses can be modified. Imagery was chosen as a target because of its significant role in behavior therapy techniques. Resent evidence on the facilitative effects of imagery in paired-associate learning suggested to the experimenters the use of performance on a…

Three procedures for use in assessing imagery behavior were examined with the intent of finding a prognastic tool that would help the behavior therapist evaluate the applicability and/or the progress of an imagery intervention such as covert sensitization or implosion therapy. The authors attempted to replicate and extend portions of earlier…

One member from each of two object pairs was assigned as a reinforcer during a generalized requesting intervention using manual signs or graphic symbols with two severely handicapped learners (age 18). Prior generalized request training and reinforcer use did not influence effectiveness of later instruction in acquisition and generalized use of…
