Interpersonal perception and personality disorders: Utilization of a thin slice approach

Study 1 expands upon previous research by looking at the ability of untrained raters to detect pathological traits within a normal population of college students. In Study 1, 30-s video clips of 81 target persons were shown to 42 raters. Ratings of traits of personality disorders made by thin slice raters reliably predicted scores on the personality pathology measures obtained from the targets themselves and from close peers. Study 2 is a preliminary examination of how pathological rater traits impacts thin slice accuracy. In Study 2, peer and self-report data were examined regarding 87 thin slice raters. Raters who exhibited traits of narcissistic personality disorder were significantly less accurate in making personality predictions regarding targets. Three clusters of personality items were identified based on rater characteristics related to accuracy in predicting behavior.     

The regression trunk approach to discover treatment covariate interaction

The regression trunk approach (RTA) is an integration of regression trees and multiple linear regression analysis. In this paper RTA is used to discover treatment covariate interactions, in the regression of one continuous variable on a treatment variable withmultiple covariates. The performance of RTA is compared to the classical method of forward stepwise regression. The results of two simulation studies, in which the true interactions are modeled as threshold interactions, show that RTA detects the interactions in a higher number of cases (82.3% in the first simulation study, and 52.3% in the second) than stepwise regression (56.5% and 20.5%). In a real data example the final RTA model has a higher cross-validated variance-accounted-for (29.8%) than the stepwise regression model (12.5%). All of these results indicate that RTA is a promising alternative method for demonstrating differential effectiveness of treatments.

Warm and homely or cold and beautiful? Sex differences in trading off traits in mate selection

Prior research and theory suggest that people use three main sets of criteria in mate selection: warmth/trustworthiness, attractiveness/vitality, and status/resources. In two studies, men and women made mating choices between pairs of hypothetical potential partners and were forced to make trade-offs among these three criteria (e.g., warm and homely vs. cold and attractive). As predicted, women (relative to men) placed greater importance on warmth/trustworthiness and status/resources in a potential mate but less importance on attractiveness/vitality. In addition, as expected (a) ratings of ideal standards partly mediated the link between sex and mate choices, (b) ideal standards declined in importance from long-term to short-term relationships, with the exception of attractiveness/vitality, and unexpectedly, (c) sex differences were higher for long-term (compared to short-term) mate choice. Explanations and implications are discussed.     

Short- and Long-Term Impact of Receiving Genetic Mutation Results in Women at Increased Risk for Hereditary Breast Cancer

Forty-seven unaffected women from high-risk breast cancer families who had received results for hereditary breast/ovarian predisposition genes between 1 month and 5 years ago were interviewed regarding their experiences. Women responded to open-ended questions. The initial emotional turmoil reported by most was generally short lived. However, the impact of genetic testing went beyond the individual to the extended family and social context, particularly in the short-term. A common theme was the difficulty associated with divulging a result to family members, who were also adjusting to their own result. The majority of carriers reported advantages that were both physical (options for surveillance programs and prophylactic surgery) and emotional (reduced uncertainty, increased awareness of options and knowledge about risk, preparation time). Most carriers reported no change in lifestyle although some reported discovering their mutation status as a positive life-changing experience. Implications for genetic counseling and further research are discussed.     

A visit from the Candy Witch: factors influencing young children's belief in a novel fantastical being

Factors hypothesized to affect beliefs in fantastical beings were examined by introducing children to a novel fantastical entity, the Candy Witch. Results revealed that among older preschoolers, children who were visited by the Candy Witch exhibited stronger beliefs in the Candy Witch than did those who were not. Among children who were visited, older children had stronger beliefs than did younger children. Among children who were not visited, those with a high Fantasy Orientation believed more strongly than did those with a low Fantasy Orientation. Belief remained high one year later. At both time points, the number of other fantastical beings in which a child believed was significantly related to belief in the Candy Witch.     

Reliability and validity of the Parent-Child Relationship Inventory (PCRI): evidence from a longitudinal cross-informant investigation

Psychometric properties of the Parent-Child Relationship Inventory (PCRI) were examined using data collected from adolescents and their parents in the Fullerton Longitudinal Study. Results revealed acceptable internal consistency for most scales and moderate to high 1-year stability for all scales. Both parents' PCRI scores correlated with their views of family climate. Cross-informant concordance was pervasive and strong between mothers' PCRI scores and adolescents' perceptions of the parent-child relationship and family climate; however, convergence was not evident between fathers' and adolescents' reports. Additionally, poor performance was observed for the Autonomy scale. In conjunction with other research on parent-adolescent relationships, concerns are raised regarding the utility of scales to contrast mother-adolescent with father-adolescent relationships.     

False pretense and deviant exploitation: Fortunetelling as a con

This paper presents a dramaturgical analysis of the backstage manipulations carried out by practitioners of the deviant occupation known as fortunetelling. It is generally believed that con games require a dishonest victim, although many practitioners manipulate their impressions with clients who are seeking a service rather than a profit. The group of fortunetellers included in this study are nonbelievers and hence fundamentally misrepresent themselves to their clients. Drawing upon depth interviews with 21 non‐Gypsy fortunetellers, including two key informants, six backstage routines are analyzed. Each routine in the fortuneteller's performance presents the client with a frontstage definition of the activity designed to sell more and more “psychic services.” The implications of the dramaturgical analysis of con games are discussed.     

Testing Case Formulation Hypotheses in Psychotherapy: Two Case Examples

We describe two cases that illustrate and demonstrate the effectiveness of a case formulation–driven approach to psychotherapy in which the therapist, in collaboration with the patient, develops a hypothesis (formulation) about the psychological mechanisms that cause and maintain the patient’s difficulties, uses the formulation to guide intervention, and collects data to test the formulation and evaluate the effectiveness of the intervention plan. As shown by the cases reported here, a key strength of this collaborative empirical process is that it enables the patient and therapist to quickly determine when a treatment is failing and take action to rescue it.
