Results of a study involving 13 color-deficient and 15 color-normal pupils in grades three through six, show no evidence of relationship between color vision and achievement. Supports findings of previous studies by Lorenz and McClure (1935), and Shearron (1965). (CJ)

Compares the performance of preschool and kindergarten children who were presented with 18 paired associates to learn under three conditions: control, mnemonic test-time instructions, and mnemonic plus retrieval instructions. Results are consistent with the claim that younger children need more explicit prompts. (RH)

The judgment of vocal affect was studied in 19 language delayed children and 19 children with normal language. The children identified utterances spoken in an angry, happy, or sad tone of voice. The language delayed children made significantly fewer correct judgments. (Author/SEW)

Three experiments examined whether the phenomena of visual search for single characters (Sternberg, 1966) generalizes to word and word-category search when target and distractor sets had varied and consistent mappings across trials. Previous results were replicated. Four principles of search are discussed within a theory of automatic/control…

The effect of uncertainty of movement increased reaction time and movement time significantly in a simple task of running for mildly retarded eight- and ten-year old children. No change in performance was noted for normal children. (Author/PN)

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. (Author/PN)

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…
