Evaluating the convergence of muscle appearance attitude measures

There has been growing interest in the assessment of a muscular appearance. Given the importance of assessing muscle appearance attitudes, the aim of this study was to explore the convergence of the Drive for Muscularity Scale, Somatomorphic Matrix, Contour Drawing Rating Scale, Male Figure Drawings, and the Muscularity Rating Scale. Participants were 76 men and 103 women who each completed four measures of body image that were meant to evaluate two distinct domains of appearance attitudes: muscularity and body fat. For both genders, data indicated low convergence among muscularity measures, but high convergence among body fat measures. For men, the Drive for Muscularity Body Image subscale exhibited the greatest concurrent validity with behaviors used to increase muscularity. The results are discussed in light of the selection of methods for the assessment of muscle appearance attitudes.     

Self-injurious behavior and the efficacy of naltrexone treatment: a quantitative synthesis

People with mental retardation, autism, and related developmental disabilities who self-injure are treated with a wide array of behavioral techniques and psychotropic medications. Despite numerous reports documenting short-term and some long-term changes in self-injury associated with the opiate antagonist naltrexone hydrochloride, no quantitative review of its efficacy has been reported. We conducted a quantitative synthesis of the peer-reviewed published literature from 1983 to 2003 documenting the use of naltrexone for the treatment of self-injurious behavior (SIB). Individual-level results were analyzed given subject and study characteristics. A sample of 27 research articles involving 86 subjects with self-injury was reviewed. Eighty percent of subjects were reported to improve relative to baseline (i.e., SIB reduced) during naltrexone administration and 47% of subjects SIB was reduced by 50% or greater. In studies reporting dose levels in milligrams, males were more likely than females to respond. No significant relations were found between treatment outcomes and autism status or form of self-injury. Results are discussed with respect to future efficacy work related to study outcomes and the pharmacological treatment of self-injury.     

Change blindness and the primacy of object appearance

A large body of work suggests that the visual system is particularly sensitive to the appearance of new objects. This is based partly on evidence from visual search studies showing that onsets capture attention whereas many other types of visual event do not. Recently, however, the notion that object onset has a special status in visual attention has been challenged. For instance, an object that looms toward an observer has also been shown to capture attention. In two experiments, we investigated whether onset receives processing priority over looming. Observers performed a change detection task in which one of the display objects either loomed or receded, or a new object appeared. Results showed that looming objects were more resistant to change blindness than receding objects. Crucially, however, the appearance of a new object was less susceptible to change blindness than both looming and receding. We argue that the visual system is particularly sensitive to object onsets.     

Development and validation of the verbal commentary on physical appearance scale: Considering both positive and negative commentary

Two studies describe the development and validation of the Verbal Commentary on Physical Appearance Scale (VCOPAS). In Study 1, 320 undergraduate female students completed the scale and factor analyses were conducted. Study 2 included 246 undergraduate female students and a confirmatory factor analysis (CFA) replicated the initial factor structure. The final VCOPAS consists of 21 items and contains three subscales (Negative Weight and Shape, Positive Weight and Shape, and Positive General Appearance). The total scale and subscales demonstrated good internal consistency and test–retest reliability (all >.70). Significant correlations were found between VCOPAS subscales and measures of physical appearance-related feedback, body image disturbance, and self-esteem. Regression analyses indicated the utility of the Negative Weight and Shape, Positive Weight and Shape, and Positive General Appearance subscales in explaining significant variance associated with body image disturbance and self-esteem. The VCOPAS is likely to be useful in future research examining the role of appearance-related commentary in the development and maintenance of body image dissatisfaction and eating disturbance.     

Decomposing retrieval and integration in memory for actions: a multinomial modeling approach

Typically, action phrases are recalled better if participants are asked to enact the phrases than if they are just asked to remember them. When investigating which processes constitute this enactment effect a difficulty is that observable effects in standard memory tests are ambiguous because such tests require several processes. In the present article, we introduce a multinomial model that decomposes observable memory performance into a retrieval parameter and a parameter concerning the item-specific processing and integration of an action phrase. These parameters are estimated from free recall and cued recall performance. The model fitted the data of two experiments designed to test it. Experiment 1 demonstrated the basic usefulness of the model by showing expected differences in the integration parameter in the absence of unexpected differences in the retrieval parameter. Experiment 2 extended the conditions under which the model is useful by showing expected differences in the retrieval parameter even in the presence of unexpected differences in the integration parameter. Together, these findings support our theoretical framework according to which enactment generally boosts integration of action phrases, but increases retrieval only for phrases with context cues.     

NUANCE: Naturalistic University of Alberta Nonlinear Correlation Explorer

In this article, we describe the Naturalistic University of Alberta Nonlinear Correlation Explorer (NUANCE), a computer program for data exploration and analysis. NUANCE is specialized for finding nonlinear relations between any number of predictors and a dependent value to be predicted. It searches the space of possible relations between the predictors and the dependent value by using natural selection to evolve equations that maximize the correlation between their output and the dependent value. In this article, we introduce the program, describe how to use it, and provide illustrative examples. NUANCE is written in Java, which runs on most computer platforms. We have contributed NUANCE to the archival Web site of the Psychonomic Society (www.psychonomic.org/archive), from which it may be freely downloaded.     

Five-factor model (Big Five) personality traits and universal-diverse orientation in counselor trainees

In this study the authors explored the relationship between five-factor model (FFM: Big Five) personality traits (J. M. Digman, 1990; R. R. McCrae & O. P. John, 1992; J. S. Wiggins & P. D. Trappnell, 1997) and universal-diverse orientation (UDO; M. L. Miville et al., 1999) in counselor trainees. FFM traits were measured using the NEO-Personality Inventory-Revised (P. T. Costa & R. R. McCrae, 1992). Statistically significant relationships were found between UDO and one of the Big Five personality traits (Openness to Experience) in counselor trainees. Further regression analysis suggested a relationship between UDO and a particular facet of Openness to Experience, Openness to Aesthetics. This finding suggests that counselor trainees who are open to the creative expressions of others may be comfortable working with a wide variety of clients. These results suggest that counselor training that encourages experiences of aesthetic diversity in addition to an exploration of values may promote trainees' ability to work with diverse clients.     

The relative influence of attitudes and subjective norms from childhood to adolescence: between-participant and within-participant analyses

Children and adolescents (ages 8-16) were asked to indicate their behavioral intentions, attitudes, and subjective norms for 34 behaviors. Between-participant and within-participant analyses demonstrated that attitudes and subjective norms were good predictors of behavioral intentions both singly and in combination. In addition, attitudes generally were better predictors than were subjective norms both across behaviors and across participants. Most importantly, however, there were no differences in the relative importance of attitudes and subjective norms in predicting behavioral intentions across age groups.     

Empirical evidence supporting the conceptual relatedness of object representations and internal working models

The proliferation of new developmental and clinical theories broadly termed "psychoanalytic" demands a methodology for making systematic comparisons to establish the commonalities and distinctions among them. This article presents an empirical method for the comparative evaluation of such theories. The Mother-To-Child Object Representation / Internal Working Model Q-sort is a 100-item instrument constructed to assess the quality of the prototypical mother's object representation and internal working model of her child at age five. Object relations judges were asked to sort these items for a complex, differentiated, integrated object representation of a five-year-old, attachment judges for a secure, coherent, freely valuing internal working model of a five-year-old. Judges' criterion Q-sorts in each group yielded a composite criterion Q-sort of the quality of the prototypical mother's mental representation of her child according to each group's theoretical perspective. The Spearman-Brown correlation between the two composite criterion Q-sorts was r = .90, p < .001 , suggesting that when confined to a 100-item common vocabulary, judges representing each theoretical construct agreed on the conceptual relatedness of object representations and internal working models. The theoretical constructs of object representations and internal working models share common assumptions in need of further exploration.
