Abstract : Both male and female rats were used to investigate the effects of positive and negative subcortical stimulation on a conditioned escape task. The study utilized (1) non-contingent stimulation and (2) stimulation during extinction. Studies were made to test the 'Theory of Choice' and to investigate horizontal and vertical line preferences in the rat using a simple T-maze. A pilot study was also made in an attempt to furnish some basic data to determine a feasible acquisition criterion in animal escape learning. (Author)
