Cognitive and perceptual measures as predictors of fourth-grade achievement

This study used a multivariate approach and longitudinal design to examine the relationship of early perceptual and cognitive development to later school achievement. The extent to which a set of 4th-grade achievement measures could be predicted from a set of variables collected when the students were in first grade was determined through a series of canonical and multiple correlation analyses. These results were compared to results of an earlier phase of the study. Similarities between the two phases indicated that: (a) A measure of visual perception added significantly to the prediction of achievement afforded by consideration of sex and academic aptitude. (b) The variables used to predict achievement may differ somewhat between boys and girls. (c) The usefulness of sex as a predictor of school achievement depends upon the specific achievement area under consideration. Differences in the two phases involved the extent to which sex was a predictor of a specific achievement area.     

A guide to McCarthy interpretation

The aim of the present study was to develop a system of tables to facilitate interpretation of the McCarthy Scales of Children's Abilities. Tables are presented that organize the McCarthy subtests according to Bannatyne's, Sattler's, and Meeker's systems of interpretation. In addition, tables that organize the McCarthy Scales into categories that reflect factors likely to influence various subtests are presented. These tables will provide a more structured approach to McCarthy interpretation and a straightforward empirical method for generating hypotheses regarding individual strengths and weaknesses in intellectual ability.     

The effects of extrinsic reinforcement on intrinsic motivation

In this paper, the role of extrinsic reinforcement in intrinsic motivation is discussed in terms of Deci's cognitive attribution theory. The competing response hypothesis and the frustration hypothesis are presented as alternative modes of analysis. “Undermining” is the phenomenon proposed by the cognitive attribution theorists that accounts for reported decrements in intrinsically motivated behaviors following external rewards. The literature regarding undermining in token economy research is critically evaluated. The author concludes that: (a) Cognitive attribution theory lacks parsimony, in that extant reinforcement analysis can account for undermining with equal facility. (b) Undermining is of little significance as a concept, due to its elusive and transient impact on operant behavior.     

Interjudge agreement in classifying students as learning disabled

Eighteen judges with backgrounds in assessment, decision making, and learning disabilities were asked to use an array of information to differentiate learning disabled and nonlearning disabled students. Each judge was provided with forms containing information on 42 test or subtest scores of 50 school-identified LD students and 49 non-LD students. Judges were extremely inaccurate in their classifications and in little agreement with each other. Also, it appeared that different judges emphasized different factors when making their decisions. The results suggest that, given current definitions of the condition called “learning disabilities,” there is considerable doubt that school personnel can accurately and reliably identify such students.     

Does the WISC-R measure verbal intelligence for nonenglish-speaking children?

Zarske, Moore, and Petersen's (1981) article that examined the factor structure of the WISC-R for “diagnosed learning disabled” children was critiqued. These authors concluded that the WISC-R “is an appropriate measure of general intellectual abilities” (p.407), but the present author suggests that this conclusion does not follow from their factor analytic data. The makeup of the sample also is questioned, and implications of their findings for the practitioner are discussed.     

Information, systems and the construction of meaning

The term ‘information’ is seldom given a careful definition and is in practice used in more than one sense. In particular there is often a failure to distinguish ‘information’ from concepts such as ‘knowledge’, ‘belief’ and ‘meaning’. One attempt to build a suitable conceptual scheme with a firm philosophical basis has been made by Dretske. In corporate contexts, the meaning and significance of information can be seen as lying in its contribution to the maintenance and development of ‘systems’ of activities. It follows that a competent analysis of corporate information requirements and a specification of the characteristics of data collection, communication and processing needed to satisfy them, both depend on an appropriate form of systems analysis. The methods used by Checkland and Wilson provide means of exploring the requirements, while the approaches of Beer and Espejo define patterns of information flow necessary for their realization. As advanced techniques of information processing develop, clearer understanding of such approaches and their theoretical basis will become important in exploiting their potential.     

Youth on the street: Abuse and neglect in the eighties

This paper discusses the findings of a study of runaways and homeless youth who were interviewed on the street the last week of every month on five week nights from late afternoon until 2 a.m. over a period of one year. The data derived from 489 interviews provided some interesting insights. Two distinct groups emerged from the analysis, generating a tentative hypothesis that the true "runners" tend to leave their homes with the intention of not returning and thus their runs are extended; the second group, designated "in and outers," use the run as a temporary coping mechanism. Their runs tend to be impulsive and of short duration. The study found that runaways (in particular the runners) are at great risk of being drawn into illegal activities. Major factors affecting this risk are distance from home and length of time on the run. A significant proportion of the youth interviewed had run from substitute care arrangements, and a disturbing implication emerging from the research is that adolescents in our society suffer from systemic abuse and neglect. One outcome of this piece of research was the opening of a safe house for early runners in January 1987. The operation of the house includes careful compilation of data to further advance understanding of the runaway population and its needs.
