Investigates the perceptual basis of metaphor by asking 5-, 7-, and 10-year-old children and adults to pair and discuss films of natural objects, both stationary and moving. Concludes that motion information makes metaphoric similarity relatively easy to perceive and influences the form of descriptive metaphors. (Author/CB)

Reports the results of structured interviews with mothers of 29 children three and one-half to 12 years of age, documenting the development of four categories of food rejection based on distaste, danger, disgust, and inappropriateness. Suggests that lack of contamination sensitivity in younger children is due to their belief that chemical…

Replies to argument presenting evidence against a model of habituation during early infancy which was based on the selective adaptation of feature detectors. (Author/BB)

Assesses preschoolers' and adults' relative ability to solve classification problems in which a similarity criterion is the only criterion appropriate for solution. Also investigates effects of the salience of individual dimensions on solution-relevant similarity classifications. (AS)

Comparisons of age and test score correlations, comparisons of cross-sequential means, and trends of means for diagnostic subgroups and normal controls suggest developmental delay for all measured skills at all ages for autistic and schizophrenic children. Findings also suggest a trend for steady prepubertal cognitive skill development, followed…

Two experiments were conducted to assess the relative effectiveness of stimulus shaping and "traditional" prompting procedures with six low-functioning retarded children (one-six years old). Stimulus shaping procedures required less training time than to criterion, resulted in fewer errors, required fewer and less intrusive therapist's prompts,…

Reports on age differences found in children's (1) ability to execute appropriate differences in the uses of color while completing partially drawn scenes; and (2) sensitivity to differences between heraldic, gradation, harmonic, and pure use of color in a matching task. (GC)

Forty-eight neonates were randomly assigned to view a moving stimulus either in the horizontal or the upright position, with or without added vestibular stimulation and with or without pacifier sucking. Results indicate that vestibular proprioceptive stimulation, provided horizontally or semi-vertically, significantly enhanced visual tracking.…

Serial habituation of visual fixations was investigated through a design permitting cross-sectional, within-subject longitudinal, cohort longitudinal, and time-lag analyses. Results suggested that for all ages habituation was under way to the parts of the stimulus in order of the realitive saliencies. No one methodology appeared to significantly…

The Rorschach was given to 60 school children in two designs: chronological age (CA) and mental age (MA) orthogonal and CA=MA. Responses were scored for Form Accuracy, Complexity, Movement and Friedman's Developmental Level (DL) Scoring System. The results suggest that the DL system does assess MA independently of CA. (Author/DEP)

To assess the development of monocular slant perception as well as the relative effectiveness of different sources of information, 90 children in first, third, and fifth grades and 30 college adults were asked to make judgments of surface slant on the basis of monocular texture gradient information. (Author/JH)

Five developmental experiments examine the role of context in visual search. (Author/JH)

Twenty-four subjects at each of four grade levels (first, third, fifth, and college) made judgments of physical slant of surfaces with three levels of variability. Absolute error of judgment decreased with age, but texture variability had no effect at any grade level. (JH)

The size of the effective visual field during the first weeks of life is found to depend on two factors: It increases with age, but contracts in the face of competition from ongoing activity such as fixation of a central stimulus or nonnutritive sucking. (Author/SB)

This study investigated the hypothesis that as children become older they are increasingly likely to make efficient use of accessible retrieval cues. Results confirmed the hypothesis. (ST)
