Reactions of preschool children from urban and rural Quebec to several animated and other representational television characters were obtained. Visual elements consistently appealing are identified, and responses are reviewed for sex, cultural, and location differences. Application of results in the production of a televised antismoking promotion…

Describes a computer-based methodology that obtains simple timed responses to sets of words and word-like nonsense items, then presents pilot data depicting estimated vocabulary knowledge and relating it to word frequency and decision response time. (FL)

Tests seven- , 10- , and 13-year-olds for developmental differences in processes and strategies involved in geometric matrix solution and the relationship between strategy differences and item complexity. (AS)

A study involving eight boys with autism and eight boys with Down syndrome (ages 6-10) with similar adaptive behavior levels used an ecological approach to study the in-depth structure of the behavior stream. Narrative records were collected and analyzed based on duration and frequency of behaviors. Each record was analyzed by marking the behavior…

A study of foreign students' English acquisition used short-term memory tasks to determine if phonological encoding of visually presented verbal material occurred during reading. Students not using oral repetition in English showed greater phonological interference and longer reaction times. Correlation with reading proficiency was small.…

Down's syndrome adolescents were compared with age- and I.Q.-matched non-Down's syndrome retardates on a two-point finger tapping task. Results supported the hypothesis that Down's syndrome retardates show a deficit in developing and utilizing preprogramed motor sequences. (CM)

Ratcliff's theory of memory retrieval which posits parallel processing and Sternberg's serial processing explanation of memory scanning are reviewed and contrasted. Discrepancy between the two theories may arise because they focus on different aspects of the data. If scanning without comparisons takes place, the two views may be reconciled.…

A cross-section method was used to study the developmental changes in elementary decoding and encoding processes of 163 Swedish-German bilingual students, whose length of residence in Sweden varied. It was demonstrated that decoding in two languages, expressed in terms of reaction time, develops faster than encoding. (SW)

Assessed effects of sleep restriction and extension on 9- to 12-year-olds' neurobehavioral functioning. Found that modest sleep restriction led to improved sleep quality but to reduced reported alertness. Children who extended sleep improved significantly from baseline their performance on the digit forward memory test and reaction time on the…

Three experiments obtained same-different judgments from children and adults to trace normal development of local and global processing of hierarchical visual forms. Findings indicated that reaction time was faster on global trials than local trials; bias was stronger in children and diminished to adult levels between ages 10 and 14. Reaction time…

Forty-eight male and 54 female left-handed junior college students in Stockholm were grouped according to familial sinistrality and strength of handedness. Performance on computerized reaction time (RT), maze, and verbal ability tests was assessed. Sex was the only factor differentiating left-handers on RT, and no factors affected verbal ability.…

Hypothesized that arithmetic calculating procedures and types of problems that necessitate more subproblems will lead to longer solution times. Data from 36 third grade students who mentally computed problems with sums greater than 20 and less than 100, confirmed both hypotheses. (RH)

This study assessed the differential effectiveness of two types of response delays on correct responding (with communicative gestures) by three individuals with severe mental handicaps to training instructions. Results showed that response delay was effective in increasing the number of correct responses in two of the three individuals. (DB)

Tested three competing structural equation models concerning auditory inspection time (AIT) and cognitive ability. Found that auditory inspection times near age 11 correlate most strongly with later high IQ. (ET)

Two experiments conducted with 49 Chicano high school students, aged 15-17, found that balanced-proficient bilingual speakers had slower rates of cognitive information processing at the level of short-term memory than did unbalanced bilingual speakers. The groups did not differ in rates of cognitive information processing at the simpler level of…
