Investigated simultaneous occurrence of emergent stimulus-response relations (functional equivalence) and stimulus-stimulus relations (stimulus equivalence). Trained 4- and 5-year olds to emit specified responses to pairs of stimuli in one setting (original training) and to emit other responses to one member of each pair in another setting…

Whisker deflection is an effective conditioned stimulus (CS) for trace eyeblink conditioning that has been shown to induce a learning-specific expansion of whisker-related cortical barrels, suggesting that memory storage for an aspect of the trace association resides in barrel cortex. To examine the role of the barrel cortex in acquisition and…

Children and adults were trained and tested on formation of novel simple discriminations and conditional stimulus relations. Subjects who formed these sets were trained and tested on formation of stimulus equivalence classes. A modest majority of children matched directly paired stimuli; a few matched indirectly paired stimuli. All normal adults…

Five children with autism were taught to match printed words to corresponding pictures. Participants' speed of learning was compared across three training conditions, each involving a 5-s delay of reinforcement, using a within-participants alternating treatments design. In the cue-value condition, a verbal phrase of approval (e.g., "good!") was…

An experimental treatment approach to teaching alcoholics controlled drinking utilizing a multi-modal treatment approach is presented. This approach included aversion conditioning contingent upon emission of such undesirable drinking behaviors as gulping, drinking straight drinks, Blood Alcohol Level of 0.065 or greater, and time between drinks.…

Rabbits were given reinforced training of the nictitating membrane (NM) response using separate conditioned stimuli (CSs), which were a tone, light, and/or tactile vibration. Then, two CSs were compounded and given further pairings with the unconditioned stimulus (US). Evidence of both overexpectation and summation effects appeared. That is,…

Reports on three experiments that do the following: 1) investigate the motivational and reinforcing structure underlying male sex role action in a three-person (a female and two males) exchange; and 2) contribute new information on females' interpersonal evaluation of males expressing masculine sex typed and androgynous sex role orientation. (MW)

We investigated the influence of the protein synthesis blocker anisomycin on contextual memory in the terrestrial snail "Helix." Prior to the training session, the behavioral responses in two contexts were similar. Two days after a session of electric shocks (5 d) in one context only, the context conditioning was observed as the significant…

We examined some conditions under which a response acquired as a tact might facilitate the establishment of a mand. We taught 3 participants with developmental disabilities to tact the items ranked highest and lowest in a preference assessment and subsequently tested to see if the responses occurred as mands. All participants manded for the highly…
