Different measures of risk perceptions yield different patterns of interaction for combinations of hazards: smoking,family history and cardiac events

Some combinations of hazards yield disease rates greater than would be expected from the risk attributable to each hazard in isolation. However, perceptions are often more consistent with the combined risk being seen as less than the sum of the individual factors, raising concerns over the validity of some measures of risk perception. Here, 249 adults estimated the risk of cardiac events for four hypothetical men, described as having high or low levels of smoking and family history of heart disease. Three distinct measures were used. A 9‐point scale produced a strong sub‐additive interaction, a 101‐point scale produced a weaker sub‐additive interaction, and an unbounded scale produced no interaction. In this study, as in all previous research, scales with relatively few points (here a 9‐point scale) yield sub‐additive interactions. Given the consistency of results yielded by such scales, irrespective of context, it is concluded that these scales are not valid for perceptions of multiple risk factors.

Development of the Spiritual Transcendence Index

In response to calls from the scientific community for improved conceptualizations and measures of spirituality, we describe the concept of "spiritual transcendence" and the development of the Spiritual Transcendence Index (STI). Spiritual transcendence refers to a perceived experience of the sacred that affects one'sself–perception, feelings, goals, and ability to transcend one'sdifficulties. The STI is an eight–item measure of this construct developed and refined based on rational considerations, input from three focus groups of religious leaders, and a reciprocal process of empirically testing the item pool and revising it across six successive surveys. The final scale, together with measures of related constructs, was tested in 220 randomly selected community residents. Although further study of the scale is needed, the STI demonstrated high consistency and validity across several samples in these initial exploratory studies.     

Catechol-O-methyltransferase Val158Met genotype affects neural correlates of aversive stimuli processing

It was previously shown that variation of the catechol-O-methyltransferase (COMT) gene modulates brain activity during the processing of stimuli with negative valence, but not for pleasant stimuli. Here, we tested whether the COMT genotype also modulates the electrophysiological correlates of emotional processing and explored whether the environmental factor of life stress influences this effect. Using the early posterior negativity (EPN) paradigm, event-related brain potentials were measured in 81 healthy individuals during the processing of pictures that evoked emotions of positive and negative valence. As was hypothesized, the COMT genotype affected the EPN amplitudes for unpleasant stimuli, but not for pleasant ones. Specifically, Met/Met carriers respond more sensitively to unpleasant stimuli, as compared with Val/Val carriers. We did not find evidence that life stress moderates the effect of the COMT genotype on emotional stimuli processing.     

Exploring numerical proportions in a unique context: The group support systems meeting environment

This paper reports the results of a study examining issues of group gender composition in a meeting setting employing group support systems (GSS). Research examining the effects of numerical proportions on group behavior has traditionally been conducted in settings where use of technology by groups is minimal. This research, however, examines the impact of varying group gender composition on brainstorming, social interaction patterns, and attitudes when technology is employed to facilitate and structure group process. In this setting, we find no gender-related differences in computer-based brainstorming. In the accompanying oral discussions, however, males display a higher proportion of task-related answers than females and uniform groups express more maintenance behavior than groups consisting of mixed genders. Our findings also show that uniform gender groups perceive greater participation in the decision process than skewed groups. Despite these gender-related differences, we found relatively little support for Kanter's Numerical Proportions Model in a GSS setting, given the range of measures explored in this study.     

Gender Bias in the Evaluation of Female Faculty at The Citadel: A Qualitative Analysis

The purpose of this study was to investigate the possibility of gender bias in student ratings of female faculty at The Citadel. Four (Caucasian) female faculty members, one at each level of academic rank, and four (Caucasian) male cadets were interviewed to determine their views on bias in the instructional process, especially with regard to ratings of faculty by students. From the data we concluded that there is a contradiction between beliefs about gender bias and the actual presence of bias for both faculty and students. Women are subjected to a double standard, and in the military setting of The Citadel, nontenure track female faculty are doubly penalized. Faculty women believe gender bias is part of the institutional culture, and contrapower harassment in ratings of female faculty by male students is likely.     

Relationships between Rorschach variables as relevant to the interpretation of structural data

The protocols of 100 adult nonpatients who had been administered the Rorschach twice in a long term temporal consistency study were used in this study. Separate intercorrelational matrices were calculated for each testing with R partialed. Means of the pairs of partial correlations were calculated, the square root of which is considered the best available estimate of the correlation between each pair of variables. Fifteen of the 120 partial correlations are considered to be significant. The findings are discussed in terms of their potential relevance for configurational interpretation of structural data.     

Paired-Associate Learning in Attention-Deficit/Hyperactivity Disorder as a Function of Hyperactivity-Impulsivity and Oppositional Defiant Disorder

A paired-associate learning (PAL) test was administered to 22 community volunteers without disruptive disorders and 197 children (7.5–13.5 years-old) presenting with the inattentive and combined subtypes of attention-deficit/hyperactivity disorder (ADHD) either in combination with or without oppositional defiant disorder (ODD). Participants were screened for learning disorders. In comparison to non-ADHD participants, children with ADHD achieved worse PAL and made errors rated as more acoustically and less semantically similar to the correct paired associates. These deficits were not related to hyperactivity–impulsivity or comorbid ODD. These results suggest that ADHD children are less competent at PAL and use less efficient learning strategies than their non-ADHD peers.     

But it's only an inkblot

The nature of the Rorschach is discussed using data from three temporal consistency studies with children of different ages, plus two other studies in which the retest reliability question was approached by experimental manipulation. It is postulated that the test response reflects the basic psychological styles or response tendencies that have developed within the personality, plus representations of the more private world of the person. The challenge for interpretation and research is to differentiate which of the test elements reflect each of these features, and to determine how they merge to create the response during a very brief time interval.
