Between- versus within-family factor analyses of cognitive abilities

Confirmatory factor analyses of the 15 cognitive abilities tests from the Hawaii Family Study of Cognition were conducted on between-family (BF) means and within-family (WF) differences for 370 AEA (Americans of European ancestry) and 116 AJA (Americans of Japanese ancestry) sibling pairs. Difference chi-square significance tests, goodness-of-fit indices, and congruence coefficients for the estimated loadings on four specific cognitive abilities factors and on the second-order general intelligence factor nearly all indicated that the between-family factor structures were not significantly different from the within-family structures for both AEA and AJA siblings (the AEA and AJA structures were also not significantly different). The similarity of the BF and WF structures suggests that the genetic and environmental influences underlying cognitive abilities are “intrinsic” in nature, that is, not just due to between-family differences in culture, status, values, and fortuitous cross-assortative mating.     

Gender and gender-role identity influences upon self- and other-reports of communicative competence

This study examines the influence of gender-role identity on interpersonal perceptions of communicative competence in a natural setting over an extended period of time. After working in small task-oriented groups for 15 weeks, 146 students (74 females, 72 males) completed a questionnaire containing measures of gender-role identity (Bem Sex Role Inventory) and communicative competence [J. M. Wieman, Explication and test of a model of communicative competence. Human Communication Research, 1977, 3, 195–213]. A three-way ANOVA (masculinity, femininity, gender) was used for analysis. Predictions based on prior models were only partially supported. Findings suggest that gender-role identity functions in more complex ways than prior models suggest. For all dimensions of communicative competence, gender-role identity resulted in different patterns for males and females. Furthermore, comparisons of self- vs other-perceptions indicate the possibility that one model may hold for self-perceptions and another for other-perceptions.The authors gratefully acknowledge the helpful comments contributed by Kenneth R. Wilson and Kristina Troost.     

Social phobia in disabled workers with chronic musculoskeletal pain

The present study assessed the prevalence and impact of social phobia and other anxiety disorders in disabled workers with chronic musculoskeletal pain. Potential participants were 200 disabled workers consecutively referred to an interdisciplinary tertiary care centre. A two stage screening process was used in which: (a) a self-report battery was given during a pre-admission visit, and (b) preplanned selection criteria were applied to the self-report instruments to select patients for a structured diagnostic interview. Fifty-four of the 146 patients who provided complete responses on the self-report battery met criteria for interview. Twenty-six patients (17.8%) met DSM-IV criteria for a current anxiety disorder and, of these, 16 (11.0%) were diagnosed with social phobia. Subjects with social phobia rated themselves as having less social support than subjects with no psychiatric disorder, but the groups did not differ in pain-related life interference, personal control, or health care utilization. The results suggest that social phobia is over-represented in disabled workers with chronic musculoskeletal pain and should be noted as a comorbid condition that may compound both suffering and disability.     

Ken and Barbie at life size

There has been considerable discussion in both the scientific literature and general media concerning the appropriateness of the body shape and proportions of the Ken and Barbie dolls, the most popular dolls in modern history. The greatest concern has been of the possible influence that these, and other cultural ideals for body shape, may have on young children. However, these concerns have been based entirely on the subjective interpretation of how one perceives the body dimensions of the dolls relative to an adult size. We therefore used our skills in anthropometry and the rules of allometry to scale the dolls to an adult height to determine the dimensions that these dolls would assume at this adjusted size. These were compared to actual proportions of several representative adult groups of predominantly Anglo-Australian males and females. The critics have been justified in their opinions since both Barbie and Ken are thin relative to the reference samples. Barbie's mean girth z-score relative to a reference cross-section of the young adult population was –4.2. This indicates that the probability for such a body shape is less than 1 in 100,000. Ken is more realistic at about 1 in 50.Special thanks to Melissa Clough, Brendon Dews, Loretta Downie, Judy Morris, and Kim Birchall.     

The lived experience of disability

In this paper I reflect upon my personal experience of chronic progressive multiple sclerosis in order to provide a phenomenological account of the human experience of disability. In particular, I argue that the phenomenological notion of lived body provides important insights into the profound disruptions of space and time that are an integral element of changed physical capacities such as loss of mobility. In addition, phenomenology discloses the emotional dimension of physical disorder. The lived body disruption engendered by loss of mobility includes a change in the character of surrounding space, an alteration in one's taken-for-granted awareness of (and interaction with) objects, the disruption of corporeal identity, a disturbance in one's relations with others, and a change in the character of temporal experience. The loss of upright posture is of particular significance since it not only concretely diminishes autonomy but affects the way one is treated by others. Such a change in posture is, therefore, particularly disruptive in the social world of everyday life. An understanding of the lived body disruption engendered by disability has important applications for the clinical context in devising effective therapies, as well as for the social arena in determining how best to resolve the various challenges posed by chronic disabling disorders.I should like to thank Frances Chaput Waksler for her helpful comments on my work.     

The ideal‐self inventory: A new measure of self‐esteem

This article reports on some research in progress developing a new measure of self‐esteem which we have called the Ideal‐Self Inventory (ISI). The inventory is based on a constructivist approach and simply asks participants to list ten characteristics to describe their ideal self together with the ten opposite characteristics to describe their not ideal self. The ISI has been tested on over 100 student volunteers and correlates significantly with the adult version of the Coopersmith Self‐Esteem Inventory. The applications of this new measure are discussed with particular reference to counselling and psychotherapy.     

Social approval and helping

An experiment was conducted to examine the role played by social approval as an incentive for helping behavior. After filling out the Marlowe-Crowne Social Desirability Scale, 95 female undergraduates were asked to make donations to a research fund under either public or private conditions. The following predictions, derived from social learning theory, were supported: (a) more money is donated under public conditions than under private conditions (p < .01), (b) more money is donated by individuals high in need for approval than those low in need for approval (p < .05), and (c) the effect of need for approval on donating is greater under public conditions than under private conditions (p < .05).
