Epidemics in perspective

Irrational responses to patient with AIDS, particularly in regards to the transmissibility of HIV (human immunodeficiency virus) are examined from an historical and psychosocial perspective. Although these responses are similar to those reported from past epidemics such as plague and leprosy, they are in direct conflict with our current level of understanding regarding the transmission of this virus. Their genesis may relate to the human penchant to react to illness metaphorically. In order to allay effectively public concern about the transmissibility of AIDS, it is essential to recognize the metaphor associated with venereal disease in general and AIDS in particular.     

Harmonic accents in inference of metrical structure and perception of rhythm patterns

Research on rhythmic structure is somewhat fragmented, due in part to differential use ofterminology and a lack of research on the timing of harmonic accents. In this study, a harmonic and a temporal accent were pitted against each other in such a way as to form different rhythm patterns. In addition, two harmonic conditions that varied in the frequency of chord presentations (i.e., the composite rhythm) but not in the frequency of chord changes (i.e., the harmonic rhythm) were presented. Musicians and nonmusicians were requested to report perceived rhythm patterns inan attempt to determine the relative salience of the harmonic and temporal accents. In addition, a behavioral measure of the perceivedmeter was taken. Results indicated that the location of chord changes was the main determinant of subjects’ rhythmic perceptions and the perceived onset of a measure. Furthermore, although subjects primarily inferred different meters based on the composite rhythm, an interaction of metrical and rhythmic choices was found, indicating that perception ofrhythm patterns and inference of metrical structure may notalways be independent.     

Ethnic group-by-generation interactions in WAIS scores in the Hawaii family study of cognition

This paper is a comparatively small-scale replication of a paper by DeFries, Corley, Johnson, Vandenberg, & Wilson (1982), using that subset of the DeFries subject group that was administered the Wechsler Adult Intelligence Scale (WAIS) and comparing parent vs. offspring performance of Americans of European and of Japanese Ancestry. Like DeFries et al., significant ethnic group-by-generation interactions were obtained in WAIS scores, suggesting the existence of substantial cultural influences on cognitive-test performance.     

Self-Regulation: Reminders and Suggestions from Personality Science

La littérature sur l’autorégulation est couramment accusée de faiblesse théorique. Il est possible que les avancées dans les recherches sur la personnalité puissent ouvrir des horizons dans ce secteur. Notre objectif est double. Nous rappelons d’abord des distinctions conceptuelles qui, bien que parfois négligées, sont essentielles dans les études contemporaines sur la personnalité et incontournables pour accéder au niveau théorique dans la littérature sur l’autorégulation. Nous disons ensuite que ceux qui font des études fondamentales et appliquées sur l’autorégulation auraient intérêt à assimiler les progrès récents concernant la dynamique et la structure de la personnalité intra‐individuelle. Nous passons en revue la théorie de base et les recherches sur l’architecture des systèmes de la personnalité intra‐individuelle, ainsi que les retombées de ce travail dans trois domaines d’application: la psychologie du travail/industrielle/organisationnelle, la psychologie clinique et la santé. The self‐regulation literature commonly is said to lack theoretical order. This paper explores the possibility that advances in personality science may foster clarity in this literature. Our goals are two‐fold. We remind readers of conceptual distinctions that are central to contemporary personality science, that are necessary to the attainment of theoretical order in the self‐regulation literature, yet that sometimes are overlooked. Secondly, we suggest that basic and applied students of self‐regulation would profit by capitalising on recent advances in personality science that explore intra‐individual personality structure and dynamics. We review theory and research on the architecture of intra‐individual personality systems and applications of this work to three domains: health, clinical, and work/industrial/organisation psychology.     

Theoretical Purity Versus Theoretical Layering in Marriage and Family Therapy

There seem to be two competing streams of thought about the use of theory in the marriage and family therapy literature: theoretical purity versus integrationism. We examined influence of theoretical orientation on client experience in therapy. Level of academic training (masters' versus doctoral degree) was investigated as a possible confounding variable. Results suggest that therapists in private practice are less inclined to practice pure forms of therapy.     

When fit indices and residuals are incompatible

Standard chi-square-based fit indices for factor analysis and related models have a little known property: They are more sensitive to misfit when unique variances are small than when they are large. Consequently, very small correlation residuals indicating excellent fit can be accompanied by indications of bad fit by the fit indices when unique variances are small. An empirical example of this incompatibility between residuals and fit indices is provided. For illustrative purposes, an artificial example is provided that yields exactly the same correlation residuals as the empirical example but has larger unique variances. For this example, the fit indices indicate excellent fit. A theoretical explanation for this phenomenon is provided using relationships between unique variances and eigenvalues of the fitted correlation matrix.     

Action and coping planning with regard to dental brushing among Iranian adolescents

The aims of this study were two-fold: (i) to examine the validity of the proposed three-factor structure (intention, action-, and coping planning) in an Iranian sample of adolescents, and (ii) to assess the predictive ability of the Theory of Planned Behavior (TPB) measures of action planning and coping planning for dental brushing. Eight hundred adolescents were randomly selected to participate in the study. 90% (721) of adolescents agreed to participate. Perceived behavioral control, action and coping planning scales and a self-report questionnaire related to dental brushing behavior were completed by the adolescents at baseline. One month later (time-point 2), the adolescents were asked to reassess their frequency of dental brushing over the four week period. Data were analyzed by a confirmatory factor analysis (CFA) on an original three-factor structure (intention, action plan, and coping plan). A hierarchical linear regression analysis was also performed. The CFA for the original three-factor structure showed a good fit index (χ(2)?=?637.60, degrees of freedom df?=?116), goodness-of-fit index (GFI)?=?91, and root mean square error of approximation (RMSEA)?=?0.079. Adjusting for demographic variables, action- and coping planning together accounted for 7.9% of the variance associated with dental brushing behavior at one month. In conclusion, results suggest that action planning and coping planning are associated with higher frequency in dental brushing among Iranian adolescents.     

Social data analysis instruction and the MISSIS system

Social data analysis instruction is an enterprise providing experiences to develop problem solving skills. A proper focus upon analysis can best be provided with a data analysis package stressing simplicity rather than complexity. MISSIS is such a system, and it is designed to operate on small computers. Small technology can provide a training ground for making sound decisions in analyzing data.     

NORMUL: A FORTRAN program for testing multivariate normality

NORMUL is a FORTRAN program that provides a test of whether data conform to a multivariate normal distribution. The method involves correlating Mahalanobis distances for observed data with expected chi-square percentile values. This obtained correlation is then tested for significance by empirically evaluating the probability of its belonging to a distribution generated from multivariate normal data.
