Learning to categorize perceptually similar stimuli can result in people becoming more sensitive to differences along perceptual dimensions that are relevant to category membership and/or less sensitive to equivalent differences along irrelevant perceptual dimensions. These effects of acquired distinctiveness and acquired equivalence may be caused…

From a perceptual learning perspective, infants use social information (like gaze direction) in a similar way as other information in our physical environment (like object movements) to specify action possibilities. In the current study, we assumed that infants are able to learn an affordance upon observing an adult failing to act out that…

Sensory judgments improve with practice. Such perceptual learning is often thought to reflect an increase in perceptual sensitivity. However, it may also represent a decrease in response bias, with unpracticed observers acting in part on a priori hunches rather than sensory evidence. To examine whether this is the case, 55 observers practiced…

Fifty two- to three-year olds performed paired-associate or control tasks with response items that were related or unrelated. Children in the related task performed more slowly than children in the unrelated task. Findings suggest that children in the related task experienced interference in the acquisition or retrieval of paired-associate items.…

Findings of this Israeli study suggest that perception is affected by lables, learning, and selective attention; that these effects are determined developmentally; and that as age increases, the effects of verbal cues diminish, while the effects of perceptual cues increase. (Author/DLS)

Explores the relationship between drawing pictures and the development of reading skills in preschool and primary grades. Maintains that a definite link exists between the two and briefly notes some of the relevant research. Concludes that further investigation is warranted. Includes an 11-item related bibliography.
