The spread of encoding concept was tested visually by having subjects view pictures which varied in contour completeness. The hypothesis was supported that as contour completeness decreased, the amount of perceptual analysis and memory performance would increase. (Author/MH)

An experiment was conducted to examine the effects of presentation mode, picture content, and serial position upon the recall of brief television news items. Fifteen items were presented in either video- or audio-only mode to 40 subjects. The results are discussed in terms of various imagery hypotheses. (Author)

The study sought to identify some of the variables controlling the severely aggressive behavior of two severely retarded children (ages 9 and 14). Experiments conducted under various conditions showed that, while aggressive behaviors sometimes serve as an escape function, the behaviors can be terminated through reduction of the causative situation…

The Children's Television Workshop "3-2-1 Contact" project is a series of documentary programs on science and technology subjects aimed at 8- to 12-year-olds. Based on research on children's television viewing, the series attempts to pique children's interest, alter their stereotypes of scientists, and attract them to the experience of…

Studies the effects of distinctive features on incomplete picture recognition for three to four year olds, five to six year olds, and adults. (Author/SS)

A reaction time paradigm was used to investigate developmental differences in ability to rotate and compare imaginal representations. Subjects were 16 children from the third and fifth grades, and eight college students. (Author/MP)

Focuses on the differential representation of mental functions between the two human cerebral hemispheres. The manner in which right hemisphere function laterizes in childhood was studied in 98 five- to twelve-year-old children. (CM)

Outlines a concentrated in-service visual training program which incorporates (1) perceptual effects of visual stimuli, (2) synthetic and natural stimuli, (3) non-verbal stimuli, (4) pictorial communication, (5) visual persuasion, and (6) creative visualization. (Author/CMV)

Discusses factors that will aid teachers in their efforts to spark inner-city students to understand modes of discourse and therefore write interesting themes. (Author/RL)

Reports on two experiments, one performed on infants, the other on adults, designed to examine the issue of categorical perception of speech contrasts in infants in relation to linguistic processing and the innateness theory of speech perception. (AM)

Tested the hypotheses that errors of ommission would occur more frequently than errors of commission and errors would be related to stimulus complexity. A total of 48 children from grades 1 and 3 were given a memory task (involving visual and haptic memory) for recognition of random polygons. (MS)

A total of 84 Israeli middle- and upper-middle-class nursery school, second and fifth grade children were subjects for a study investigating parallel shifts in dimensional salience and the dominance of these dimensions as organizing principles in memory. (MS)

Pigeons learned discrimination rapidly and responded differentially to pictures seen for the first time. The essential feature of a natural discrimination--which is the ability to cope with natural ranges of variation--was approached and earlier experimental results were extended using other classes of stimuli. (Author/RK)

Two experiments are presented in which lateralization of monaural, auditory input affected the evaluation of verbal passages. Discusses lateral differences in evaluating auditory stimuli in the framework of the left hemisphere's specialization for the holistic processing of objective information and the right hemisphere's specialization for the…

Several experiments investigated the effect of word length on recognition thresholds for both familiar English words and unfamiliar pseudowords, the thresholds measured both with and without a stimulus mask. (Editor)
