Comparison of Visual “Safe-” and “Shock-”Cue Importance in Discriminated Avoidance Learning
Rats reached criterion for discriminated avoidance acquisition significantly faster under a 180-sec. than under a 30-sec. safebox confinement. Reversal (Exp. 1) and extinction (Exp. 2) of the original avoidance response were both facilitated by removal of either original safe or shock cues. No interaction was found between length of confinement in acquisition and safe- or shock-cue removal. The results were interpreted as only partially supportin…
Figural After‐effects, Sensory Coding, Expectation and Experience
Eight experiments on figural after‐effects (FAEs) are reported. The roles of induced set, and of experience in making judgements in a set‐free environment, were analysed. It was found that set can play a dominant part in the generation, or pseudo‐generation, of FAEs. Unless exceptional precautions are taken, set is likely to contaminate most reports of FAEs, and this factor probably accounts for most of the conflicting reports in the literature. …
Shape Recognition
Shape Recognition in Rats
Reasons are given for doubting whether certain of Lashley's experiments, purporting to be investigations of shape discriminations, really are such. In particular his finding concerning square-circle discrimination cannot be held to lend support to Deutsch's theory of shape recognition. An experiment is reported which shows that rats can discriminate square from circle under certain conditions of pre-training, and do so under these conditions by r…
