Sense, nonsense, and the use of personality measures

Criticize measurement-based personality research by recounting a well-known limitation: indices of relationship are often inflated because of the similarity of content across measures of presumably different constructs. In this paper we endorse the major contention of Nicholls et al. that measurement-based research may be conducted thoughtlessly, and we extend their thinking by pointing out an important underlying issue—the problem of defining what constitutes a “syndrome.” In contrast to them, however, we argue that the problems in measurement they cite do not entail the consequences they foresee and, in addition, have limited application.     

Perceived force in fatiguing isometric contractions

An integrative approach emphasizing both psychological and physiological components in force perception has started to emerge in motor psychophysics. In this experiment, the relation between isometric force (produced by the elbow flexors~ and perceived force was examined over a range of forces maintained until maximal endurance. A contralateral-limb matching procedure in which subjects estimated the force of a sustained, constant force contraction by contracting their unfatigued arm at regular intervals was employed. A linear increase in perceived force was observed during the fatiguing contractions, the rate of which depended on the level of force exerted. The sensation of force at maximal endurance was also found to vary with the force exerted. Based on the similarity between these results and those derived from electromyographic studies, we propose that observers use the efferent input to the muscle in preference to its afferent responses in judging the force of muscular contractions.     

A tutorial on some issues and methods in serial pattern research

In a review of major trends in serial pattern research, the issue of structural ambiguity and its relationship to representations of hierarchical and nonhierarchical patterns is considered. Also discussed is the role of various kinds of serial rules that can relate events within a sequence (e.g., nominal, ordinal, interval rules), as well as new developments in representing time relationships. Some practical problems that arise in the study of perception of serial structure are shown to involve its formal specification and the enlistment of appropriate controls. Major pitfalls are illustrated using recent research with music-like patterns (e.g., Deutsch, 1980).     

Dimensions of adolescent career development: A multi-instrument analysis

Dimensions of adolescent career development were assessed by several well-established, objectively scored instruments. Attention was given to the correlations between measures of academic achievement and career development. Correlations among 19 scales administered to 237 eleventh graders revealed three clusters of converging scale pairs, labeled “Certainty,” “Decision-Making,” and “Activity.” Four orthogonal factors were identified and given the following heuristic labels: “Cognitive Resources for Decision-Making,” “Decision-Making Style,” “Systematic Involvement in Career Decision-Making,” and “Decision-Making Stage/Certainty.” Results are discussed in relation to practical problems of instrument selection and score interpretation and in the context of theories of adolescent career development.     

The relative efficacy of predicting IQ from mother-child interactions using ratings versus behavioral count measures

The relative efficacy of using ratings versus behavioral count measures to predict intelligence from mother-child interactions was investigated for 45 mother-child dyads who constituted a heterogeneous sample with respect to socioeconomic status. These dyads were observed when the children were 36 months of age; children were tested with standardized IQ tests at 36 and 60 months. Social interactions between mothers and children were coded from video tapes with two different systems by independent observers. The behavioral count system was used to code second-by-second the duration and frequency of behaviors during the session. The rating system was used to judge maternal behaviors on three scales following the session. A series of forced stepwise multiple regression analyses compared the predictive utility of the two systems both concurrently and over time. The ratings of maternal behavior yielded high correlations with child IQ both concurrently and over time and were not contributed to significantly by the behavioral count measures. The authors speculate that ratings proved more efficacious because the raters could make more subjective and intuitive judgments concerning maternal behavior.     

Language and Literacy in a Developmental Perspective

Snow et al. have provided an unusually comprehensive, even-handed, and thoughtful review of research on early reading development. Here we expand on an important theme—the value of a developmental and transactional perspective. Using results from studies of verbally precocious children and children with language impairments, we illustrate the qualitatively changing nature of the task of learning to read, and its connection to oral language development. We also discuss the bidirectional influence of adults and children on each other. This perspective has implications for what, when, and how to teach reading.
