In a novel version of the classic dot-pattern prototype-distortion paradigm of category learning, Homa et al. (2019) tested a condition in which individual training instances never repeated, and observed results that they claimed severely challenged exemplar models of classification and recognition. Among the results was a dissociation in which…

This article concerns the effect of context on people's judgments about sequences of chance outcomes. In Experiment 1, participants judged whether sequences were produced by random, mechanical processes (such as a roulette wheel) or skilled human action (such as basketball shots). Sequences with lower alternation rates were judged more likely to…

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…

Details two experiments that deal with the questions: Does organization influence recognition performance? and Does recognition involve search and retrieval? (GB)

Four commissurotomy patients were tested for ability to match tachistoscopically presented stimuli with pictures in free vision, according to either structural appearance or functional/conceptual category. (Editor)

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 report describes the experimental studies conducted to examine the role of mental structures in four different areas of research. The first area involves the structural analysis of isolable subsystems involved in visual and auditory pattern recognition. The second area involves the study of the encoding and retrieval of emotional or…
