Abstract:

A feature analytic process is proposed as a basic mechanism in the encoding and storage of visual shapes by humans. It is hypothesized that local features, encoded as feature prototypes plus deviations, are stored in memory according to their positional relationships in the pattern. Two studies explored methodologies for the study of feature selection and attempted to determine if humans would agree in their selection of features. Inspection of the results showed that humans do agree in their selection of features and tend to repeat the selection of similar visual configurations as features across patterns. It is proposed that the consistency of feature selection, both within and between patterns, is a function of both the informational properties of the feature and the population of features present in the patterns.
