The algebra of factorial indeterminancy

Certain properties and consequences of factor indeterminancy are deduced from an orthogonal transformation derived by Ledermann [5]. The first deduction is the matrix of cosines between maximally distinct factor axes which represent the same factor solution. This result is used to investigate the indeterminancy of factor extensions.     

Personalized versus standard role plays in the assessment of depressed patients' social skill

Chronically depressed outpatients participated in a study of the role-play assessment of social skill. Patients role-played a series of standard situations typical of those employed in social-skills research and additional scenes drawn from critical situations in their personal lives. These “personalized” role-play situations were perceived as more relevant by patients and resulted in more discomfort and less skillful interpersonal behavior than standard scenes. Behavioral measures derived from personalized role plays were also found to be more strongly related to measures of depression than the same measures derived from the standard role-play scenes. Implications of these findings for the role-play assessment of social skill are discussed.     

Working through: in-session processes that promote between-session thoughts and activities

This study examined whether clients' ratings of the working alliance as well as their perception of cognitive-behavioral (CB) and psychodynamic-interpersonal (PI) techniques (delivered by therapists who used both) were associated with clients' intersession processes (i.e., their thoughts about therapy and therapeutic activity between sessions). Seventy-five clients who were currently in therapy at a large university counseling center participated in the current study. Multilevel regression analyses demonstrated that alliance and clients' perceptions of their therapists' use of PI techniques were positively associated with clients' general thoughts about therapy between sessions. Also, stronger alliances were associated with more therapeutic activities between sessions and more positive (and less negative) thoughts about therapy between sessions. In addition, clients at later sessions who described their therapists as using more PI techniques also reported engaging in more therapeutic activities between sessions (after controlling for the variance in the other variables, such as use of CB techniques). Clients' perceptions of their therapists' use of CB techniques in the most recent session were not related to thinking about therapy or therapeutic activities after controlling for the variance in the other variables.     

Hostile Attributional Bias,Negative Emotional Responding,and Aggression in Adults: Moderating Effects of Gender and Impulsivity

The current study examined the main effects of hostile attributional bias (HAB) and negative emotional responding on a variety of aggressive behaviors in adults, including general aggression, physical aggression, relational aggression, and verbal aggression. Effects of both externalizing (anger) and internalizing (embarrassment/upset) negative emotions were considered. In addition, the moderating roles of gender and impulsivity on the effects of HAB and negative emotional responding were explored. Multilevel models were fitted to data from 2,749 adult twins aged 20–55 from the PennTwins cohort. HAB was positively associated with all four forms of aggression. There was also a significant interaction between impulsivity and HAB for general aggression. Specifically, the relationship between HAB and general aggression was only significant for individuals with average or above‐average levels of impulsivity. Negative emotional responding was also found to predict all measures of aggression, although in different ways. Anger was positively associated with all forms of aggression, whereas embarrassment/upset predicted decreased levels of general, physical, and verbal aggression but increased levels of relational aggression. The associations between negative emotional responding and aggression were generally stronger for males than females. The current study provides evidence for the utility of HAB and negative emotional responding as predictors of adult aggression and further suggests that gender and impulsivity may moderate their links with aggression.

Compliance and personality: the vulnerability of the unstable introvert

The aim of the study was to assess the relationship of compliance with Eysenck's three personality dimensions: psychoticism, extraversion, and neuroticism. Three groups of participants (prison inmates, college students, and university students) completed the Gudjonsson Compliance Scale (GCS) and the Eysenck Personality Questionnaire (EPQ). As predicted, compliance correlated positively with neuroticism and negatively with extraversion in all groups, whereas for psychoticism the correlation was positive among the prison inmates, negative for college students, and non‐significant for university students. A quadrant analysis according to Eysenck's original two‐dimensional framework (neuroticism–stability and introversion–extraversion) showed that compliance was highest among unstable introverts and lowest among stable extraverts. The findings are discussed in relation to recent work on person‐type approaches. Copyright © 2004 John Wiley & Sons, Ltd.     

System JLZ – rational default reasoning by minimal ranking constructions

We present a powerful quasi-probabilistic default formalism for graded defaults based on a well-motivated canonical ranking construction procedure, System JLZ. It implements the minimal construction paradigm and verifies the major inference principles and inheritance desiderata, including rational monotony for propositions and structured cumulativity for default conditionals. With help from a structured ranking semantics for defaults, it also avoids some drawbacks of semi-qualitative entropy maximization and other competing accounts.     

Providing an escape option reduces retaliatory aggression

The purpose of this study was to examine whether providing an explicit means to escape future attacks by a provocative fictitious participant reduces retaliatory aggression. Using a laboratory measure of aggression (the Point Subtraction Aggression Paradigm), 25 participants were given the opportunity to earn points with monetary value on a fixed ratio (FR) 100 schedule, and to subtract points from a fictitious participant on an FR 10 schedule. Aggressive responding was defined as the number of point subtraction responses by the participant. Aggressive responding also produced intervals free from further attack by the fictitious participant. Provocation was manipulated by having the fictitious person subtract points from the participant. Each participant next completed the same task with an explicit FR 10 escape response option added. The escape option produced intervals free from attack identical to the aggressive option, but without taking points away from the fictitious participant. Results indicate that the availability of an escape response attenuated aggressive behavior in response to provocation. Aggr. Behav. 00:000–000, 2005. © 2005 Wiley‐Liss, Inc.
