The relationship between temperament and personality: An exploratory study

Although the terms temperament and personality are often used interchangeably in the literature and clearly are conceptually related, there is little empirical data to illuminate their relationship. In this exploratory study we measured temperament (using the Dimensions of Temperament Survey), and personality (using the Eysenck Personality Questionnaire), in young adolescents and in adults. Some age and sex differences in relationships between the measures and their correlations were found. The temperament dimension of adaptability was clearly related to Eysenck's Extraversion factor and reactivity to Neuroticism in females. More substantial relationships emerged in the adult sample than in the adolescent group, Our data, combined with that of a 1984 Australian study using different techniques, provides substantial support for measurable overlap between some dimensions of temperament derived largely from the developmental literature, and Eysenck's personality theory.     

Loss of Religious or Spiritual Identities Among the LGBT Population

Lesbian, gay, bisexual, and transgender (LGBT) individuals are at risk of having negative experiences with religion because of mainstream religions’ non‐LGBT‐affirming stance. Negative religious experiences can lead to religious or spiritual (R/S) struggles and loss of R/S identity to maintain sexual identity. The authors describe R/S abuse, R/S struggle, and how these can result in loss of R/S identity in LGBT individuals. They provide a case study and discuss counseling implications and areas for future research.     

Behavioral treatment of adult obesity: Attentional controls and a 2-year follow-up

This research included controls for both amount of extra-therapy attention focused on target behaviors and for quality and duration of attention provided during therapy. Two pairs of therapists each conducted one group for each of four experimental conditions: nonspecific therapy, nonspecific therapy + attention prompting, behavior therapy, behavior therapy + positive induction (procedures designed to maximize favorableness of expectancies). Sixty-five obese adults ( OVERWEIGHT = 52%) attended 12 weekly group sessions and 3-month and 2-yr follow-ups. Ratings of expectancies, credibility and therapist characteristics were equivalent in all experimental conditions. Attrition was low (9.7%) and Ss averaged 1–2 lb weight losses per week during treatment, while improving concurrently in eating habits, cardiovascular fitness and adjustment. However, only participants who were in groups conducted by the therapist pair which was rated especially ‘democratic’ maintained average weight losses at the 2-yr follow-up. These results demonstrate the potentially vital role of several ‘nonspecific’ factors in long-term outcomes associated with behavioral treatments for adult obesity.     

The impact of posttraumatic growth,transformational leadership,and self-efficacy on PTSD and depression symptom severity among combat Veterans

Previous research has established self-efficacy as essential to postdeployment adjustment among Veterans, and perceived transformational leadership is well known for its positive effects on follower outcomes across contexts. However, little is known regarding how transformational leadership may relate to posttraumatic growth and self-efficacy in fostering psychological wellbeing among combat Veterans. The purpose of this study was to examine the role of transformational leadership in predicting posttraumatic stress disorder (PTSD) and depression symptoms among combat Veterans, as well as how posttraumatic growth and postdeployment coping self-efficacy may influence these relations. The study sample consisted of 130 combat Veterans recruited from a university, Veterans Affairs medical center, and the greater community. Path analysis based on bootstrapped resampling revealed postdeployment coping self-efficacy and perceived transformational leadership as predictors of lower PTSD and depression symptom severity. In addition, mediation modeling revealed that postdeployment coping self-efficacy mediated the relation between transformational leadership and both PTSD and depression, while posttraumatic growth did not predict PTSD symptoms. These findings may aid in the prediction of PTSD and depression symptoms among Veterans, which may then influence pre-deployment leadership training among military personnel as well as clinical treatment protocols for Veterans.     

Multicultural Incompetence and Other Unethical Behaviors: Perceptions of Therapist Practices

The present study examined nonprofessionals' perceptions of culturally based and noncultural ethical violations. One hundred seventy-four undergraduates students read 12 vignettes depicting situations in which a clinician committed either a culturally based violation (e.g., sexist or ageist behavior) or a noncultural violation (e.g., breeching confidentiality or multiple relationship). Results indicated that participants were more likely to have unfavorable views of clinicians who had committed culturally based violations. In addition, results suggested that participants would be more likely to report a clinician who had committed a culturally based violation to a supervisor or ethics board.     

RTSYS: A DOS application for the analysis of reaction time data

RTSYS is a menu-driven DOS application for the manipulation, analysis, and graphical display of reaction time data. It can be used either in a single-task environment under DOS, with access to a set operating system commands, or as an application under Windows. All functions have context-sensitive help. RTSYS fits the ex-Gaussian distribution to reaction time data without the difficulties usually associated with numerical parameter estimation. Distribution fitting and flexible censoring and rescaling options allow RTSYS to address the problems of reaction time distribution skew and outlying responses with reasonable sample sizes. RTSYS can automatically process multiple input files from experiments with arbitrary designs and produce formatted output of statistics for further processing by graphical and inferential statistical packages. The present article reviews and explains techniques used by RTSYS and provides an overview of the operation of the program.     

Using the Criterion-Predictor Factor Model to Compute the Probability of Detecting Prediction Bias with Ordinary Least Squares Regression

The study of prediction bias is important and the last five decades include research studies that examined whether test scores differentially predict academic or employment performance. Previous studies used ordinary least squares (OLS) to assess whether groups differ in intercepts and slopes. This study shows that OLS yields inaccurate inferences for prediction bias hypotheses. This paper builds upon the criterion-predictor factor model by demonstrating the effect of selection, measurement error, and measurement bias on prediction bias studies that use OLS. The range restricted, criterion-predictor factor model is used to compute Type I error and power rates associated with using regression to assess prediction bias hypotheses. In short, OLS is not capable of testing hypotheses about group differences in latent intercepts and slopes. Additionally, a theorem is presented which shows that researchers should not employ hierarchical regression to assess intercept differences with selected samples.     

Do humans integrate routes into a cognitive map? Map- versus landmark-based navigation of novel shortcuts

Do humans integrate experience on specific routes into metric survey knowledge of the environment, or do they depend on a simpler strategy of landmark navigation? The authors tested this question using a novel shortcut paradigm during walking in a virtual environment. The authors find that participants could not take successful shortcuts in a desert world but could do so with dispersed landmarks in a forest. On catch trials, participants were drawn toward the displaced landmarks whether the landmarks were clustered near the target location or along the shortcut route. However, when landmarks appeared unreliable, participants fell back on coarse survey knowledge. Like honeybees (F. C. Dyer, 1991), humans do not appear to derive accurate cognitive maps from path integration to guide navigation but, instead, depend on landmarks when they are available.
