Interrelationships between Reading Disability and Attention-Deficit/Hyperactivity Disorder

Evidence from a number of investigations suggests a considerable overlap between reading disability (RD) and attention deficit-hyperactivity disorder (ADHD). We investigate the relationship between RD and ADHD in a cohort of 186 children 7.5–9.5 years of age, recruited explicitly to address classification and definitional issues in these disorders. Using multivariate methods, we examine the hypothesis that RD and ADHD represent separate diagnostic entities that frequently co-occur in the same individual. The results suggest that RD is characterized by deficits within the language system, in particular a subcomponent within that system, phonological processing; in contrast, such linguistic deficits are not characteristic of ADHD unless ADHD is associated with RD. When children with both RD and ADHD are examined, both the linguistic deficits associated with RD and the behavioral characteristics associated with ADHD are apparent, but these deficits are not synergistic. We conclude that RD and ADHD represent separate disorders that frequently co-occur.     

Validating Measures of Psychological Well-being by Contrasting Samples Employed in Hazardous and Less Hazardous Work

The study investigated whether differences between contrasting groups reflect significant differences in psychological well-being scores. Membership of hazardous vs. less hazardous occupations in the same profession served as proxy measures of well-being. Antonovsky's Sense of Coherence (SOC), Block & Kremen's Ego-resiliency, and Goldberg's Emotional Stability scales were validated. Study 1 compared mine rescue team members and ordinary miners (n = 34, 41) and Study 2 police special task force members and regular officers (n = 43, 41). In Study 1, SOC and job satisfaction predicted group membership. In Study 2, satisfaction with life and extraversion scales predicted group membership, as did SOC in a secondary analysis. The SOC scale could predict psychological well-being in hazardous work settings.     

Omimigrid-Pc: A new development in computerized repertory grids

A new approach to computer programs used to administer and/or analyze repertory grids is described. The system outlined here, OMNIGRID-PC, is a variation of OMNIGRID, which was designed to have broad practical and theoretical applications. The general features of OMNIGRID are discussed; then the unique features of the OMNIGRID-PC system, Versions 1.0 and 1.5, are explained in detail along with their underlying theoretical rationale. The Appendix more fully explicates the interpretive significance of the most substantive new feature of Version 3.5–Cromwell Format data collection.     

Exemplification and Constituent Realism: A Clarification and Modest Defense

In this article I present and (modestly) defend a hybrid position which we may call a Platonist constituent ontology. More specifically, I present a version of exemplification which entails (1) a certain form of Platonism, (2) a constituent ontology of ordinary objects, (3) a view of exemplification as a “tiedto” nexus, and (4) a view of properties as abstract objects that are non-spatially “in” ordinary objects. I clarify two sets of preliminary issues, present my hybrid analysis of exemplification, raise and seek to undercut an argument against my constituent realism, and surface some of the costs and benefits relevant to assessing the relative merits of relational versus constituent realism.     

Collective Intentionality,Evolutionary Biology and Social Reality1

Abstract

The paper aims to clarify and scrutinize Searle”s somewhat puzzling statement that collective intentionality is a biologically primitive phenomenon. It is argued that the statement is not only meant to bring out that “collective intentionality” is not further analyzable in terms of individual intentionality. It also is meant to convey that we have a biologically evolved innate capacity for collective intentionality.The paper points out that Searle”s dedication to a strong notion of collective intentionality considerably delimits the scope of his endeavor. Furthermore, evolutionary theory does not vindicate that an innate capacity for collective intentionality is a necessary precondition for cooperative behavior. ^{1 1}Useful comments made by the participants of the Amsterdam seminar in Philosophy and History of Economics (11 November 2002), by the participants of the Third Workshop in Collective Intentionality (Rotterdam, 12-14 December 2002), and by the editors of this special issue are gratefully acknowledged.

Temperament Styles of Nigerian and U.S. Children

Abstract

Temperament styles of 400 Nigerian children are described in reference to possible gender and age differences and compared with those of 3200 U.S. children in light of Jung's theory of temperament as modified by Myers and Briggs, one that highlights four bipolar qualities: extroversion-introversion, practical-imaginative, thinking-feeling, and organized-flexible styles. Nigerian children generally prefer introverted to extroverted styles, practical to imaginative styles, feeling to thinking styles, and organized to flexible styles. In contrast to males, females are more likely to prefer feeling and organized styles. Age differences are seen only on organized-flexible styles, with a preference for flexible styles increasing with age. In contrast to U.S. children, Nigerian children tend to express higher preferences for introversion, practical, feeling, and organized styles.     

Modulation sensitivity in the perceptual organization of speech

In a spoken utterance, a talker expresses linguistic constituents in serial order. A listener resolves these linguistic properties in the rapidly fading auditory sample. Classic measures agree that auditory integration occurs at a fine temporal grain. In contrast, recent studies have proposed that sensory integration of speech occurs at a coarser grain, approximate to the syllable, on the basis of indirect and relatively insensitive perceptual measures. Evidence from cognitive neuroscience and behavioral primatology has also been adduced to support the claim of sensory integration at the pace of syllables. In the present investigation, we used direct performance measures of integration, applying an acoustic technique to isolate the contribution of short-term acoustic properties to the assay of modulation sensitivity. In corroborating the classic finding of a fine temporal grain of integration, these functional measures can inform theory and speculation in accounts of speech perception.     

Context and Prior Impression Effects on Attention, Judgment Standards, and Ratings: Contrast Effects Revisited

The present study extended research on contrast effects by (a) examining the effect of context performances on ratings of a target performance when a prior impression of the target performer already exists, and (b) clarifying the issue of whether contrast is caused by attention to context-discrepant behavior or shifts in judgment standards. The results demonstrated that the existence of a prior impression mitigates the influence of context performances on ratings. Judgment standards were found to be unstable and dependent on information provided to raters by the experimental manipulations. Regression analyses showed that both attention and standards of judgment mediate the relationship between context and ratings. Implications of these findings for contrast effects, performance ratings, and the importance of reliable judgment standards for real-world performance appraisals are discussed.     

Emergent persons

Recent psychological theorizing about the emergence of persons makes a number of ontological claims that are not always explicit. A critical consideration of such claims reveals both considerable convergence and some points of disagreement across different psychological theories of emergent personhood. What is clear is that all such theories resist the reduction of persons to biophysical or sociocultural properties, conditions, and processes. In various ways, they each call for a nonreductionistic recognition of the sociocultural constitution of important aspects of personhood, without denying the necessity of biophysical requirements of personhood. Because standard emergentist positions in physical science and the philosophy of physical science mostly ignore the sociocultural level of reality, psychological theorizing about the emergence of persons requires an alternative ontological framework. It is proposed that an ontology of levels of reality that includes the physical, chemical, biological, sociocultural, and personal/psychological is appropriate for understanding how persons are both substantively and relationally emergent within the biophysical, sociocultural world. With such an ontological framework in place, it is possible to understand human activity in the world as the primary vehicle for both the phylogenetic evolution and ontogenetic development of persons.
