These proceedings of a hearing before the Alcohol and Drug Abuse Subcommittee include testimony about the health and educational effects of marijuana on young people. The materials describe recent findings on the extent of drug use among youth, recent changes in drug use trends, and the consequences of marijuana use on health and intellectual…

A conceptual framework of attention can be organized around three functions of attention: determining how much capacity is to be deployed (attention allocation), for how long (attention maintenance), and to which potential information sources (attention direction). Within this framework, several critical distinctions can be made between processes…

A theory of textual processing signals--cues to guide the response of any reader to a narrative text--can be evolved from Gerald Prince's theory of reading interludes and William Labov's work on narrative evaluation. An examination of these signals in two personal experience narratives written by students in remedial and freshman writing courses…

A study investigated (1) the effectiveness of giving instructions to form mental images prior to reading a text and at the conclusion of the text, and (2) sex differences in the ability of below average readers to form mental images. Subjects were 47 sixth grade students who were below average readers. The subjects were randomly assigned, by sex,…

In response to the decline in thinking, reading, and writing skills, as indicated by the latest report of the National Assessment of Educational Progress, this paper offers elementary school teachers one framework for a classroom writing program to cultivate a reading-writing-thinking connection. Based on six categories of B. Bloom's taxonomy…

The learning of word problems in mathematics is viewed as particularly difficult. The first paper in this report takes into consideration the semantic aspects of problems, by viewing the difficulties that children have solving two-step multiplication problems. An initial study was carried out with 36 children between the ages of nine and fourteen…

Based upon Ausubel's theory of meaningful learning, this study focused on the use of concept maps (diagrams that portray relationships among concepts in a given area of study) to help students identify logical relationships between a new concept and concepts already known. Relationships of a learner's prior knowledge and cognitive development to…

This analysis considers several major areas in which cognition research would seem to have pregnant implications for the conscious design of social studies texts and sketches the ways in which the structure of texts might be shaped if research were applied. The first area discussed is matching texts to significant user characterics. There are at…

Research has provided support for the existence of certain actor-observer and self-serving biases in individuals' retrospective analyses about the causes of behavior. A question that has been relatively unexplored deals with whether the findings on actor-observer differences and the self-serving pattern in attributions are generalizable to…

Part of a sustained program that has involved the design of personally tailored information systems responsive to the needs of scientists performing common research and teaching tasks, this project focuses on the procedural and content requirements for accomplishing need diagnosis and presents these requirements as specifications for an…

When adequately elaborated, the basic method of Gestalt therapy can be traced to the phenomenological field theory of Gestalt psychology. Gestalt therapy differs from Gestalt psychology not because of a difference in philosophy or method, but because of different contexts; the clinical context has different demands than those of basic research.…

Only a longitudinal study, in which retrospective reports can be verified against data collected earlier, can determine what topics tend to be reported accurately and whether certain types of individuals are more likely to be accurate reporters. A representative group of adults who became parents 50 years ago are now part of the oldest and longest…

Only a longitudinal study, in which retrospective reports can be verified against data collected earlier, can determine what topics tend to be reported accurately and whether certain types of individuals are more likely to be accurate reporters. A representative sample of women who became mothers 50 years ago are now part of the oldest and longest…

Working under the hypothesis that a child's concept of a story and his or her concept of the task of narration used to tap comprehension emerge first in social interaction, a methodology was created for studying the process of development from dependent functioning in social interaction to independent functioning based on L. Vygotsky's theoretical…

A study investigated the theory that the affective dimension of words can have a significant effect on the process of word recognition. Specifically, the study examined whether word potency (the emotional impact of a word), frequency, and certain graphic characteristics affected word recognition in the parafoveal field under very brief exposure…
