Twenty subjects at each of four age levels (8, 10, 12, and 18) rated linguistic units of prose passages in terms of their importance. Third- and fifth-grade subjects did not differentiate items in terms of their relative importance to the text and at all ages such judgments were related to recall. (Author/JMB)

Children of 200 low-income families were studied to determine possible deleterious outcomes due to maternal employment in the child's first 3 years of life. When 8-year follow-up data were controlled for maternal variables, 30 differences in outcomes were found, 27 of which favored children of workers. (Author/JMB)

Examined the relationship of ability to conserve and comprehend of logical riddles in 33 first-, third- and fifth-grade boys of average intelligence. Although both riddle comprehension and cognitive maturity as assessed by Piagetian tasks increased with grade, the relation between them was not clearly demonstrated. (Author/JMB)

The development of perspective taking was explored in kindergarten and second grade children using a referential communication task. (BRT)

Cognitive and behavioral measures were administered to heterogeneous and homogeneous Mexican-American and Anglo groups at the beginning and end of the prekindergarten year. The results suggest that the learning environments of both homogeneous and heterogeneous groups have a facilitating influence. (SB)

The relationships between perception and conservation of length were investigated in a developmental comparison of judgments of length made by 5-year-olds, 8-year-olds and adults. (GO)

Reviewed in the paper are theories and concepts about intelligence, and proposed is a theory set forth in stimulus-response terminology. Available from: Ablex Publishing Corporation, 355 Chestnut Street, Norwood, New Jersey 07648. (CL)

Subjects in grades 4 through 12 were asked to respond to the question "Who am I?" Their responses were analyzed for self-conceptions by means of a 30-category scoring system. Results were in agreement with Werner's notion that cognitive development proceeds from a concrete to an abstract mode of representation. (Author/JMB)

It was hypothesized that Piaget's argument on behalf of the reorganization of cognitive processes would gain empirical support from a color/form, matching similar objects problem for 52 6-year-olds from a variety of socioeconomic backgrounds. (Author/MS)

A series of three experiments was conducted to verify the hypothesis that age differences in paired-associate learning proficiency across adolescence stem from the development of increasing eleaborative propensity. (Author/JMB)

In this, the third article in a series on the author's teaching methods, the teaching of fractions is described. The author examines the types of errors which children commonly make. (SD)

Cites efforts to relate macro-level research (studies examining science achievement as related to the economic development of a nation), intermediate-level research (e.g., achievement as related to institutional variables), and micro-level research (cognitive development, etc.) to determine a science of teaching science.

This article analyzes the potential conflict between student evaluations of teaching and higher-level cognitive outputs by reexamining data in existing studies and utilizing rationalistic models of human behavior. The author finds that students favor professors who emphasize lower level cognitive material. (Author/JR)
