Elementary school children made same-different judgments of prototypes of letterlike forms paired with transforms of these prototypes generated on a dimension either critical or noncritical for object identification. Results challenge the view that dimensions irrelevant in object identification are ignored or not detected in graphic…

Thirty-six newborn infants were exposed to a visual stimulus until habituation was demonstrated; subjects were then presented with the same target or one of either moderate or large discrepancy from the standard stimulus. Following habituation, female infants displayed greater recovery of attention to moderate stimulus change. (SDH)

Reports research demonstrating that fourth-grade subjects could not solve a basic transverse patterning problem involving pairs of geometric forms even after 90 trials. The addition of one nonspatial dimension, however, resulted in solution. Also, the greater the number of nonspatial dimensions present, the better the learning. (Author/SDH)

A short-term memory task was used to explore the effects of verbal labeling and rehearsal on serial-position recall in mildly retarded 9-to 11-year-old children. Results support the view that verbal skills affect recall in mildly retarded children similarly to normal children. (Author/SDH)

Response rates and latencies of white, lower-, and middle-class preschool children were measured in an experimentally-induced frustration situation. Socioeconomic class differences in frustration situation. Socioeconomic class differences in frustration reactions were found; two possible hypotheses are offered in explanation. (SDH)

Recall performance of 5-, and 8-year-old children under distracting conditions was found to be inferior to recall performance under nondistracting conditions. Discussed are the similar degrees of performance differences for both age groups, the effectiveness of the distractors used, and evidence that the children adapted to the extraneous…

Preschool children were tested on their comprehension of the comparatives, "taller,""shorter,""more," and "less" in five types of sentences. Results suggest that many children can understand two-dimensional comparisons, but perform poorly on second-clause subjects pronoun sentences because of uncertainty about the referent of the pronoun. (SDH)

Cardiac response to stimulation of the left and right perioral region in infants was examined. Cardiac acceleration and ipsilateral head turning occurred more reliably to stimulation of the infant's right side than to stimulation of the left side. Results reflect a difference in sensitivity at the infant's two sides. (SDH)

The eye movements of subjects, ages 4 through 62, were recorded by a corneal reflection technique during familiarization with and recognition of random patterns of luminous dots. Findings were consistent with the views of both Soviet researchers and Piaget, that overt, perceptual activity diminishes with increasing age. (Author/SDH)

This study investigates the visual information storage capacity in 5-, 8-, 11-, and 21-year olds. A partial report technique is used to assess the amount of information that children can take in and what the course of information loss was over time. (DP)

Assesses the relative importance of synonymity and antonymity for memory encoding of words for second and sixth graders. Also, the variable of association strength is investigated for both groups through the presentation of false-recognition stimuli. (DP)

Investigates the degree to which nursery school and second grade children imitated one of two adult models. The variables of interest are (1) extent that the models had been differentiated as to proportion of reinforcement previously delivered by each, and (2) whether the model had previously reinforced imitations. (DP)

Investigates whether the asymmetry in children's acquisition of polar adjective pairs is based on linguistic factors related to differences in adult usage and frequency or on an underlying conceptual difference. Results suggest acquisition is based on an underlying conceptual asymmetry. (DP)

Examines the hypothesis that first, third, and sixth graders' recall of noun triplets would be facilitated by using (1) related pictures of nouns, (2) training in imagining relations between separate pictures of nouns, and (3) a combination of these two processes. (DP)

Assesses subjects' information output after presentation of pictorial, word, and sentence stimuli. Output is measured in two modes of response: reconstruction and verbal description. Complexity of the stimuli is demonstrated to have important effects on perceptual information processing. (DP)
