Results argue against the too frequent use of human figure drawings as a single, stable, and accurate measure of intellectual ability. (Authors/CB)

Perceptual and cognitive development were investigated in two recall tasks with 48 Ss from each of the grades kindergarten, third, and sixth. (Author)

Reports two studies. The first study compared adults and children (aged four, six, and eight) on ability to sort paintings according to artist, a conceptual task that can reveal cognitive organization. The second study compared three groups of eight- to nine-year-olds using slightly different procedures. The results showed strong developmental…

Studied discriminative and investigatory response behavior and effects of response training on children 4-5 to 6-5 years of age. (DR)

Five experiments used a categorization habituation-of-looking paradigm to investigate infants' categorization of animals and vehicles based on static versus dynamic attributes of stimuli (color images versus dynamic point-light displays). Findings showed that 6-month-olds categorize animals and vehicles based on static and dynamic information, and…

Kindergartners and second, fourth, and sixth graders were shown a series of pictures that depicted an object with increasing completeness and were asked to identify the object. Found that, with increasing age, children correctly identified the object earlier in the sequence and that reaction time was longest for second graders. (BC)

Demonstrates the need for a process-oriented, constructivist approach to understanding infants' categorization abilities. Suggests that emphasizing the distinction between perceptual and conceptual categorization has been an obstacle to forging an approach. Proposes a more microanalytic consideration of features available to infants at different…

Examined degree to which analytic and holistic modes of processing play a role in children's and adults' categorization of faces. Found a developmental trend from analytic to holistic processing and an effect of face inversion with increasing age. Seven-year-olds processed faces comparably to nonfacial visual stimuli, whereas a growing proportion…

This article discusses findings concerning the plasticity of auditory cortical processing mechanisms in adults, including the effects of restricted cochlear damage or behavioral training with acoustic stimuli on the frequency selectivity of auditory cortical neurons and evidence for analogous injury- and use-related plasticity in the adult human…

A bird study found that with sufficient time and training after hair cell and hearing loss and hair cell regeneration, the mature avian auditory system can accommodate input from a newly regenerated periphery sufficiently to allow for recognition of previously familiar vocalizations and the learning of new complex acoustic classifications.…

Trained 1- to 3-year-olds to touch a video screen displaying a unique target and appearing among varying numbers of distracters; correct responses triggered a sound and four animated objects on the screen. Found that children's reaction time patterns resembled those from adults in corresponding search tasks, suggesting that basic perceptual…
