Attainment relative to six cognitive operations and four number and computational skills was assessed for 90 elementary students using clinical procedures. Variance associated with conservation of number, seriation, and logical classification competency accounted for a significant proportion of the variance in achievement scores. (Author/MK)

To examine the association between reversal errors and neurological disorders, 409 first graders were asked to name the letters of the lowercase alphabet presented in fixed, nonalphabetical order. (Author)

The results suggested that all Ss used similar temporal frames of reference, but that hearing impaired Ss demonstrated developmental lags. (Author/DLS)

This study sought to develop the picture-interpretation strategies of fourth-grade children by providing training in the use of such verbal guidelines as "Help yourself to all the given information." The program apparently helped the children produce more inferences, but did not enhance their skills in evaluating inferences. (Author/JEG)

This theoretical model for message design directs the designer to design a block of time that optimizes the information load and message complexity within the constraints of the receiver's abilities and experience, the requirements of the source, and the capabilities and limitations of the medium.

Two experiments demonstrated that third and sixth graders consistently selected certain strategies for solving old and new, empirical and value, contradictory information. Subjects were 320 children. (MP)

A visual search task was used to investigate the development of word processing skills used in reading meaningful text, and to evaluate the relative difficulty of employing different types of units. Subjects were 20 second graders, 19 fourth graders, and 20 college students. (MP)

The optional shift performance of 52 reflective and 50 impulsive second-grade girls was assessed under two response-consequence conditions: (1) reward for correct responses only, and (2) reward for correct responses and a penalty for incorrect responses. (Author/MP)

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)

Suggests that the general ability structure for retardates is more complex than the structure for normals, containing a "stimulus trace" factor in addition to verbal-educational and spatial-perceptual parameters. (RL)

The degree of relationship between academic achievement, as assessed by college grade-point average, and information processing habits, as measured by the scales of the Inventory of Learning Processes (ILP) was investigated. Results specify differences in processing between successful and unsuccessful students. (Author/JKS)

The distinction between "stereotype" as a cognitive structure and "stereotyping" as a complex set of intra- and inter-personal processes is discussed in light of relevant research in cognitive and social psychology. (Author/EB)

Over 100 systems have been developed that permit the recording and categorizing of teacher and student behavior. The cognitive processes of practicing teachers' decision making must be studied in order to deduce a common base whereby teaching decisions could be improved. (Author/JKS)
