Optimal Mixtures of Test Types in Paired-Associate Learning (Sensory Information Processing). Final Report.
Seven experiments were run to determine the precise nature of some of the variables which affect the processing of short-term visual information. In particular, retinal location, report order, processing order, lateral masking, and redundancy were studied along with the nature of the confusion errors which are made in the full report procedure. All seven experiments were carried out with a tacistoscope and display durations were kept at 200ms or less. In six of the experiments stress was placed on having the subjects process in a known order. In five of the experiments retinal location was varied independently of processing order. The results of the experiments led to the following conclusions: (1) retinal locus is an important variable; (2) processing order is an important variable; (3) stimuli inhibit other stimuli at the sensory level and the inhibition appears to be directed from the stimuli toward the fovea; (4) letters are processed at the feature level and some features are more important than others; and (5) no acoustic confusions are made in the full report procedure.
