Kindergarten students (n=102) were randomly assigned to one of four conditions (play, puppet, picture, repetition-control) to examine the effects of play as a mediator of listening comprehension. The play condition gained more than all other conditions and all conditions gained more than the control condition. (Author/PN)

Visual screening, a mildly aversive response suppression procedure in which the child's eyes are briefly covered, was evaluated across two studies for its effectiveness in reducing topographically similar and dissimilar stereotypic behaviors of four moderately or profoundly retarded children (aged 9 or 13 years).

Based upon a sample of 1,428 randomly selected adults, this study provided evidence regarding the appropriateness of the Thematic Apperception Test in assessing interpersonal processes and examined whether the individual concerns expressed by respondents reflect their covert needs or their behavioral inclinations.

In two experiments, preschool children had better recall when the subjects and objects of sentences read aloud were also depicted pictorially. Learning was not enhanced by illustrating only the sentence subject or object. Sixteen references are listed. (Author/JJD)

Patterns of bureaucratization and democratization in voluntary organizations may be explained by four principles of embryology: (1) the irreversibility of embryological development, (2) the canalization or branching of developmental pathways, (3) the induction of developmental change by the interaction of internal stimuli, and (4) the…

To determine the auditory acuity levels and responsiveness of seven deaf blind multihandicapped young children, the authors developed systematic observation procedures that can be used by parents, teachers, and teacher aides. The advantages of this approach and suggestions for further work are described. A case study is reported. (Author)

This study, designed to determine whether contextual organizers presented before prose passages can improve learning and retention among undergraduates with no prior knowledge of the subject, compared the effects of two types of organizers--images and their verbal equivalents--as well as organizers versus a control group. Twenty-five references…

Children's abilities to judge "who is older" without using size as a cue were studied. Five-year-olds were better able to discriminate age than four-year-olds but were not equal to adults. No significant sex differences were found. (Author/RD)

A model of context effects in perception is applied to perception of letters. Perception results from excitatory and inhibitory interactions of detectors for visual features, letters, and words. The model produces facilitation for letters in pronounceable pseudowords as well as words and accounts for rule-governed performance without any rules.…

The hypothesis that overall-similarity relations structure both adults' and children's classifications of heterogeneous objects (objects that differ in a variety of ways) was supported in two experiments. When objects varied simultaneously on many dimensions, adults and children constructed classifications that maximized within-category similarity…

To examine developmental aspects of auditory sensory memory, a series of experiments was conducted on the stimulus suffix effect with the primary variables being age of subject (7 and 11 years), rates of presentation, and length of list. Effects were nearly identical across age groups when a fast presentation rate was used. (Author/DB)

Studied male students who viewed an aggressive television program or a neutral one. Half of the students were then angered by a confederate. Results indicated angered men who had seen the aggressive film were most aggressive and exhibited the lowest average pulse rates both before and after shock delivery. (Author/JAC)

Two studies were conducted with 8- and 10-year-old children to examine sources of age and skill differences in verbal analogical reasoning. Discussion focuses on the child's "problem space" for the analogy task and possible differences in task understanding that lead to strategy and process differences in older versus younger and skilled versus…

Eleven infants with Down's syndrome and 10 of 11 nonhandicapped infants operated an automatic device which enabled them to choose to listen to nursery rhymes sung or played on musical instruments. Both groups preferred the singing, and the Down's Syndrome infants had much longer response durations for the more complex auditory stimuli. (Author/DB)

Human and geometric forms were presented to 12-month-old male infants to determine if infants with a large number of minor physical anomalies would show different habituation than infants with a small number. Differences were found in dishabituation and in response decrement. (Author/RH)
