Empirical comparison of item parameters based on the logistic and normal functions

Maximum likelihood estimates of item parameters of a scholastic aptitude test were computed using the normal and logistic models. The goodness of fit of ogives specified by the pairs of item parameters to the observed data was determined for all items. While negligible differences in the limen values were found, differences in item discrimination indices indicated that interpretation of these indices requires separate frames of reference. The empirical results showed the logistic model to be a useful alternative to the normal model in item analysis.

Tests of hypothesis in a repeated measures design from a permutation viewpoint

Repeated measures designs have been widely employed in psychological experimentation, however, such designs have rarely been analyzed by means of permutation procedures. In the present paper certain aspects of hypothesis tests ina particular repeated measures design (one non-repeated factor (A) and one repeated factor (B) withK subjects per level ofA) were investigated by means of permutation rather than sampling processes. The empirical size and power of certain normal theoryF-tests obtained under permutation were compared to their nominal normal theory values. Data sets were established in which various combinations of kurtosis of subject means and intra-subject variance heterogeneity existed in order that their effect upon the agreement of these two models could be ascertained. The results indicated that except in cases of high intra-subject variance heterogeneity, the usualF-tests onB andAB exhibited approximately the same size and power characteristics whether based upon a permutation or normal theory sampling basis.This research prepared under Contract No. 2593 from the Cooperative Research Branch of the U.

Transfer of pattern recall skills may contribute to the development of sport expertise

Superior recall of domain‐specific patterns is well established as a defining attribute of expert performers. Recent studies on the developmental histories of expert team ball sport players (e.g. Baker, Côté, & Abernethy, 2003a ) also suggest that experts characteristically receive exposure to a wide range of sports in their developing years and that this related sports experience may reduce the amount of sport‐specific training needed to become an expert. This study examined whether the facilitation of expertise associated with other sport experience might arise from positive transfer of pattern recall skills from one sport to another. Expert netball, basketball and field hockey players and experienced non‐experts performed a recall task for patterns of play derived from each of these sports. Experts from sports different to those shown in the presented pattern consistently outperformed non‐experts in their recall of defensive player positions, suggesting some selective transfer of pattern recall skills may indeed be possible.

The Relational Health Indices: A Study of Women's Relationships

A new measure of women's relationships, the Relational Health Indices (RHI), comprises three scales that assess growth-fostering connections with peers, mentors, and communities. The RHI was developed using the Relational Model (Jordan, Kaplan, Miller, Stiver, Surrey, 1991; Miller & Stiver, 1997), a theory of women's psychological development. The 37-item measure assesses three conceptual dimensions of growth-fostering relationships: engagement, authenticity, and empowerment/zest. This study examined the psychometric properties of the RHI with a group of 450 students at a women's liberal arts college, providing evidence for the reliability, validity, and utility of the new measure. The factor analyses confirmed a three-subscale structure: engagement, authenticity, empowerment/zest. The RHI's components generally demonstrate good overall internal consistency. Furthermore, associations between RHI scales and convergent validation scales were significant and in the direction hypothesized. Correlations with adjustment scales varied across the RHI components. The RHI has potential for enriching our understanding of important, subtle qualities and complex dynamics of both dyadic and group relationships, especially among women. The instrument is available for use by researchers interested in continuing the scale and theory development.     

Extratest validity of selected personality assessment inventory scales and indicators in an inpatient substance abuse setting

The purpose of this study was to extend previous findings regarding the extratest validity of the Personality Assessment Inventory (Morey, 1991, 2007) scales and indicators in forensic contexts to an inpatient substance abuse setting. The Aggression Scale, and particularly the Physical Aggression subscale, related to assault history; the Suicide Scale and Suicide Probability Index related to history of suicide attempts; Antisocial Features, and particularly the Antisocial Behaviors subscale, predicted rule infractions; and the Treatment Process Index predicted treatment completion. We discuss clinical implications in the context of extant findings.     

Before Reproduction: The Distortion of Generation

Jean Baudrillard has posited a theory of ‘the precession of simulacra’, arguing that it is no longer possible to tell the difference between an image and the meaning it purports to represent because technology allows the image to precede its meaning. Christa Wolf, while researching Cassandra: A Novel and Four Essays (1984), traveled to Greece and discovered the ways in which language in the rational, Western model of civilization has been distorted. Both Baudrillard and Wolf are disturbed by the ways in which sign systems can be manipulated and generated, and both demonstrate the effect this has in the political and cultural arenas. This analysis intends to show how Baudrillard’s theories play out in Wolf’s narrative, and how Wolf resolves the problems thus posed through the shock of the aesthetic experience, which forces communication while it defies representation.

Alcohol consumption, smoking urge, and the reinforcing effects of cigarettes: an ecological study.

Smokers (N=74) who volunteered for a smoking cessation study monitored their daily experiences for up to 6 weeks prior to the quit date. Self-reports from 7,707 diary records were used to examine the associations among alcohol consumption (present in 607 diary records), situational factors, smoking, urge to smoke, and subjective consequences of smoking. Alcohol use, smoking urge, and the subjective effects of smoking were context dependent. Momentary reports of smoking and alcohol consumption were associated with one another. Alcohol use predicted smoking even when contextual factors were covaried. Alcohol use was associated with more frequent reports of urge to smoke. Alcohol was also associated with more frequent reports that the last cigarette produced a rush/buzz, was good tasting, and reduced the urge. However, effects for rush/buzz and urge reduction were qualified by interactions between alcohol use and the latency since smoking. Rush/buzz tended to be associated with alcohol use, regardless of smoking recency. Alcohol was associated with urge reduction only when the cigarette being appraised was smoked more than 15 minutes prior to the diary entry.     

Stresses reported by UK trainee counselling psychologists

This study examined stressors and psychological distress in 109 UK counselling psychology trainees. The research focus was two-fold. What is the profile of stressors that counselling psychology trainees report about the components of training? What relationship is there between this profile, and other characteristics of trainees, including their level of current psychological distress? Data from a stress survey and from the General Health Questionnaire were examined. High stress scores were found on three aspects of the stress survey (‘academic’, ‘placements’, ‘personal and professional development’), but not–surprisingly–on the aspect, ‘lack of support systems’. Significant stress differences were reported for gender and age of participants, and highly significant positive relationships were found between General Health Questionnaire and stress scores. Overall, the results suggest actions to be taken. Further research is needed to clarify unavoidable and avoidable stressors in training, and the reduction of trainees’ experience of training stress to the necessary minimum needs to be adopted as an active target by programmes.     

Male risk-taking as a context-sensitive signaling device

Evolutionary theorists have suggested that sex differences in risk-taking are due ultimately to greater intrasexual competition among men (compared with women) over access to mating opportunities. The current work provides one of the first direct tests of the hypothesis that risk-taking serves self-presentational functions associated with mating. Results of an experimental study indicated a strong positive relationship between sexual arousal and risk-taking, but only in men exposed to a romantically available female confederate who purportedly would view their risk-taking performance. Findings suggest that risk-taking can serve as a signaling device in the context of mating, that this function is sex-specific, and that it is highly sensitive both to the situational context and to the current psychological state of the risk-taker. This research highlights the utility of an evolutionary approach in understanding the proximate social psychological determinants of risky decision-making.
