Autism is currently one of the most prominent and widely discussed human conditions. Its increased prevalence has intensified the demand for effective educational and therapeutic services, and intervention science is providing mounting evidence about practices that positively impact outcomes. The purpose of this report is to describe a set of…

Previous research has shown that 3- to 4-month-old infants form a global categorical representation for cats that includes female lions, whereas 6- to 7-month-old infants differentiate between cats and lions. Three experiments using familiarization-novelty preference procedures attempted to determine whether the differentiation of a global…

Addresses two questions that may be unique to perceptual learning: What are the circumstances that produce learning? and What is the content of learning? Suggests a critical principle for each question. Provides a discussion of perceptual learning theory, how learning occurs, and what gets learned. Includes a 121-item bibliography. (DR)

Four studies examined 10- to 18-month-old infants' ability to detect and encode correlations among features in a motion event. Findings indicated that the youngest infants process static features in an event independently but do not process correlations among dynamic features; the oldest detect correlations between all three features when the…

Two experiments examined 8-month-olds' use of absolute and relative pitch cues in a tone-sequence statistical learning task. Results suggest that, given unsegmented stimuli that do not conform to rules of musical composition, infants are more likely to track patterns of absolute pitches than of relative pitches. A third experiment found that adult…

Three experiments examined 4- to 10-month-olds' perception of audio-visual (A-V) temporal synchrony cues in the presence or absence of rhythmic pattern cues. Results established that infants of all ages could discriminate between two different audio-visual rhythmic events. Only 10-month-olds detected a desynchronization of the auditory and visual…

Four experiments confirmed the widely accepted hypothesis that, although children as young as two engage in pretend play, even four and five year olds do not understand that pretending requires mental representation. Children appear to misconstrue pretense as its common external manifestations, such as actions, until at least age six. (MDM)

The impact of age effects on nonverbal memory for auditory or tactual patterns has been largely neglected in research studies. The effects of age on nonverbal memory were investigated by comparing subjects (N=120), divided by age decades into six groups (N=20), through tests using visual, auditory, and tactual items which were resistant to verbal…

Describes two experiments that examined the effects of quantity and depth of processing on elementary school children's time perception. (HOD)

Tested 32 4-year-olds and 32 6-year-olds for free and cued recall following either play-and-remember or sort-and-remember instructions and assessed them for their metamemory of the efficacy of conceptual and perceptual sorting strategies. Younger children recalled more items under sort-and-remember, whereas no recall differences were found for the…

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)

In order to examine the nature of dimensional processing in children, 20 kindergarten and 20 third grade Chinese-American children were asked to make similarity judgments for unidimensional sets of stimuli differing in color (hue), size, and shape, respectively. Age differences were generally confined to the color set. The judgments of the older…

Current research and though regarding the relationship of individual difference (ID) factors to achievement in the basic skills is reviewed. Four major categories and nine subcategories of ID factors are defined and serve as the framework for the review: status factors (age, sex, and race, ethnic group, and socioeconomic status); intelligence…
