Resilient, undercontrolled, and overcontrolled personality prototypes among persons with spinal cord injury

A sample of 199 persons with spinal cord injury (SCI) were assessed on Big Five personality dimensions using the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992) at admission to an inpatient medical rehabilitation program. A cluster analysis of the baseline NEO-FFI yielded 3 cluster prototypes that resemble resilient, undercontrolled, and overcontrolled prototypes identified in many previous studies of children and adult community samples. Compared with normative samples, this sample had significantly fewer resilient prototypes and significantly more overcontrolled and undercontrolled prototypes. Undercontrolled individuals were the modal prototype. The resilient and undercontrolled types were better adjusted than the overcontrolled types, showing lower levels of depression at admission and higher acceptance of disability at discharge. The resilient type at admission predicted the most effective reports of social problem-solving abilities at discharge and the overcontrolled type the least. We discuss the implications of these results for assessment and interventions in rehabilitation settings.     

Toward international normative reference data for the comprehensive system

We build on the work of all the authors contributing to this Special Supplement by summarizing findings across their samples of data, and we also draw on samples published elsewhere. Using 21 samples of adult data from 17 countries we create a composite set of internationally-based reference means and standard deviations from which we compute T-scores for each sample. Figures illustrate how the scores in each sample are distributed and how the samples compare across variables in eight Rorschach Comprehensive System (CS; Exner, 2003) clusters. The adult samples from around the world are generally quite similar, and thus we encourage clinicians to integrate the composite international reference values into their clinical interpretation of protocols. However, the 31 child and adolescent samples from 5 countries produce unstable and often quite extreme values on many scores. Until the factors contributing to the variability among these samples are more fully understood, we discourage clinicians from using many CS scores to make nomothetic, score-based inferences about psychopathology in children and adolescents.     

Introduction to the JPA special supplement on International Reference Samples for the Rorschach Comprehensive System

This Introduction provides an overview to the JPA Special Supplement on International Reference Samples for the Rorschach Comprehensive System (CS; Exner, 2001). It contains a history of this project and a table including all of the lead authors, their country and the type and size of their sample. Suggestions for conducting this type of research are offered, including information on normative vs. nonpatient samples, inclusion/exclusion criteria, the use of collateral instruments, and concerns relative to representativeness. Reliability and coding concerns are addressed, and information on the Popular response in Japan are reviewed. Finally, trends within and across the data are highlighted.     

Rorschach Comprehensive System data for a sample of 37 nonpatient/nondelinquent adolescents from the United States

This study is composed of 37 American adolescents, ages 15 to 17 years of age, all from the United States. The principal author was the sole examiner. Inclusion criteria are described. Interrater reliability statistics at the response level are presented along with scores for the Rorschach Comprehensive System (CS; Exner, 2003). The results revealed differences from the published norms on variables that reflect poor form quality, fewer popular responses, more attention to detail, more poor human relationship responses, and a more simplistic, affective-free approach to the environment, among others.     

Distress in response to emotional and sexual infidelity: evidence of evolved gender differences in Spanish students

The authors studied gender differences in response to hypothetical infidelity in Spanish students. Using a forced-choice methodology, the authors asked a sample of 266 participants to indicate which kind of infidelity would be more distressing: emotional or sexual. Men were significantly more distressed by sexual infidelity than were women, and women were significantly more distressed by emotional infidelity than were men. Results supported the hypothesis that particular infidelity types, which resemble adaptive problems that human beings faced in the past, contribute to the psychology of jealousy. The results are consistent with previous cross-cultural research.     

The effects of reinforcer magnitude on timing in rats

The relation between reinforcer magnitude and timing behavior was studied using a peak procedure. Four rats received multiple consecutive sessions with both low and high levels of brain stimulation reward (BSR). Rats paused longer and had later start times during sessions when their responses were reinforced with low-magnitude BSR. When estimated by a symmetric Gaussian function, peak times also were earlier; when estimated by a better-fitting asymmetric Gaussian function or by analyzing individual trials, however, these peak-time changes were determined to reflect a mixture of large effects of BSR on start times and no effect on stop times. These results pose a significant dilemma for three major theories of timing (SET, MTS, and BeT), which all predict no effects for chronic manipulations of reinforcer magnitude. We conclude that increased reinforcer magnitude influences timing in two ways: through larger immediate after-effects that delay responding and through anticipatory effects that elicit earlier responding.     

Norm-Narrowing and Self- and Other-Perceived Aggression in Early-Adolescent Same-Sex and Mixed-Sex Cliques

We examined the relations between group context and self- and other-perceptions of aggressive behavior in an ethnically-diverse sample of 168 male and female grade 7 adolescents. We used self- and peer-reports of aggression in high- and average-aggressive mixed-sex and same-sex cliques to examine whether group members would assimilate their self-report of aggression to the aggression report of their peers by way of perceived homophily or, conversely, engage in contrast and see their level of aggression as comparatively low in the face of high-aggression peers. Among boys in mixed-sex groups, comparison with highly-aggressive others resulted in a self-perception of lower levels of aggression than those perceived by their peers. Conversely, girls in mixed-sex groups reported their own levels of aggression to be higher than those perceived by their peers. We interpret these findings in terms of the notion of “norm narrowing”: rather than being set by the larger social environment, such as the school, norms are more narrowly determined within one's immediate peer group.     

Application scenarios for nonstandard log-linear models

In this article, the authors have 2 aims. First, hierarchical, nonhierarchical, and nonstandard log-linear models are defined. Second, application scenarios are presented for nonhierarchical and nonstandard models, with illustrations of where these scenarios can occur. Parameters can be interpreted in regard to their formal meaning and in regard to their magnitude. The interpretation of the meaning of parameters is the main focus of this article. Design matrices are used to describe the hypotheses tested in models and to illustrate cases in which parameters are interpretable. Also, design matrices are used to show where and how nonstandard models differ from standard hierarchical models. Coding schemes are discussed, in particular, dummy coding and effects coding. Data examples are given with data and models discussed in the literature.
