The experiment was an attempt to gain a more precise understanding of the temporal relation between the development of analytic units and equivalence relations. Two prompting procedures were used during training to pinpoint when eight subjects learned the conditional discriminations. Near simultaneous presentation of probe and training trials allowed for examination of the temporal relation between conditional discrimination acquisition and derived performances on stimulus equivalence probes. The data show that, for seven of eight subjects, a decreased reliance on prompts was coincident with the development of equivalence-consistent choices on either all or some probe trials, which suggests that the development of analytic units is sufficient to give rise to equivalence relations among stimuli.

The present thesis investigates the effects of lesions to several hypothesized learning and memory systems on the morphine conditioned cue preference on the radial maze. Lesions of the structures thought to be centered to learning systems: the lateral nucleus of amygdala, fornix/fimbria, anterior dorsal striatum and posterior dorsal striatum, were made, In Experiment One, each structure was lesioned separately. Only lesions of the lateral nucleus of amygdala blocked morphine CCP learning. In Experiment Two, rats with combined lesions of fornix/fimbria and dorsal striatum, the lateral nucleus of amygdala and fornix/fimbria, as well as the lateral nucleus of amygdala and dorsal striatum were all impaired on morphine CCP. All of the rats with combined lesions were impaired in this CCP learning. These findings suggest that the lateral nucleus of amygdala is necessary for the morphine CCP. Participation of dorsal striatum or fornix/fimbria is also required. Some hypotheses about the interactions among the structures are discussed.
