The theory proposed (recognition-by-components) hypothesizes the perceptual recognition of objects to be a process in which the image of the input is segmented at regions of deep concavity into an arrangement of simple geometric components. Experiments on the perception of briefly presented pictures support the theory. (Author/LMO)

Human visual recognition on the basis of shape but regardless of size was investigated by reaction time methods. Results suggested two processes of size scaling: mental-image transformation and perceptual-scale transformation. Image transformation accounted for matching performance based on visual short-term memory, whereas scale transformation…

The experiments reported here are aimed at exploring in more detail the possibility that context can improve perception itself. In particular, they are concerned with clarifying the conditions under which context might aid perception and with localizing the stage of processing at which context would have its effects.

This chapter describes current research in cognitive psychology and considers how this work may be applied to the design of instructional materials. The nature of knowing--and of meaningful knowing--are examined, and findings from psycholinguistics and pattern recognition are integrated to provide an understanding of concept and memorization…

A relationship was postulated between the experienced difficulty of patterns and the amount of disorientation of their reproduction. It was proposed that the underlying factor, in the comparison of Africans to Europeans, might be the development of the concept of horizontality, which reduces dependence on the perceptual pull of the prevailing…
