External Correlates of the Personality Assessment Inventory Higher Order Structures

This brief report explores the external correlates of 2 higher order structures of the Personality Assessment Inventory (PAI; Morey, 1991, 2007); Hoelzle and Meyer's (2009a, 2009b) PAI Components and Hopwood and Moser's (2011) Internalizing and Externalizing Dimensions. Scores from these higher order structures were correlated with life-event data including education, marital status, employment, suicide attempts, psychiatric hospitalizations, trauma, medical problems, hallucinations, paranoid ideation, drug abuse, alcohol abuse, and arrest. Although some differences were noted, the results showed that both Hoelzle and Meyer's Components and Hopwood and Moser's Dimensions were meaningfully correlated with a wide range of life outcomes in a conceptually consistent manner. Overall, these findings provide support for the utility of these higher order variables.     

The Suicide (SPI) and Violence Potential Indices (VPI) from the Personality Assessment Inventory: A Preliminary Exploration of Validity in an Outpatient Psychiatric Sample

Assessing risk of harm to self and others is an important component of psychological assessment, although methods for risk assessment vary considerably. The Personality Assessment Inventory (PAI) is frequently administered to evaluate general psychological functioning, as well as to provide information about suicide and violence risk. The purpose of this study was to evaluate the construct validity of the PAI Suicide (SPI) and Violence Potential (VPI) indices in a sample of 158 psychiatric outpatients referred for psychological and neuropsychological assessment within a large northeastern academic medical center between 2007 and 2011. Results generally supported the convergent and divergent validity of both SPI and VPI when evaluating groups with and without a history of suicide and violence risk, and effect sizes were moderate to large even after controlling for other covariates. SPI and VPI scores were also found to vary significantly across different psychiatric groups in ways that would be expected. Finally, we explored the relationship between SPI and VPI, and executive functioning impairment??a neuropsychological variable found to be associated with impulsive self and other-harming behaviors. Consistent with prior research, SPI and VPI were found to be significantly elevated in groups demonstrating executive dysfunction. The implications of these findings and specifically the utility of using SPI and VPI in the assessment of risk are discussed.     

Apes' and children's understanding of cooperative and competitive motives in a communicative situation

Chimpanzees (Pan troglodytes) and bonobos (Pan paniscus) (Study 1) and 18- and 24-month-old human children (Study 2) participated in a novel communicative task. A human experimenter (E) hid food or a toy in one of two opaque containers before gesturing towards the reward's location in one of two ways. In the Informing condition, she attempted to help the subject find the hidden object by simply pointing to the correct container. In the Prohibiting condition, E held out her arm toward the correct container (palm out) and told the subject firmly 'Don't take this one.' As in previous studies, the apes were at chance in the Informing condition. However, they were above chance in the new Prohibiting condition. Human 18-month-olds showed this same pattern of results, whereas 24-month-olds showed the opposite pattern: they were better in the Informing condition than in the Prohibiting condition. In our interpretation, success in the Prohibiting condition requires subjects to understand E's goal toward them and their behavior, and then to make an inference (she would only prohibit if there were something good in there). Success in the Informing condition requires subjects to understand a cooperative communicative motive - which apparently apes and young infants find difficult.     

Effects of slow-release caffeine and a nap on driving simulator performance after partial sleep deprivation

A driving simulator was used to evaluate the effectiveness of a 30-min. nap and 300-mg slow-release caffeine as countermeasures to drivers' sleepiness induced by partial sleep deprivation. 12 participants were allowed 45 hr. time in bed at the laboratory. Driving performance then was measured twice--at 9 a.m. and at 1 p.m.--by a 45-min. driving task on a simulator. Subjective sleepiness/alertness and mood were assessed four times on the Stanford Sleepiness Scale and the Profile of Mood States. Driving performance was assessed as Lane Drifting, Speed Deviation, and Accident Liability. A 30-min. nap opportunity and 300 mg of slow-release caffeine both were successful in counteracting drivers' sleepiness. The remedial effect of slow-release caffeine lasted longer than that of the nap, that is, it was also effective in the afternoon session. This suggests that slow-release caffeine represents a valuable countermeasure that, in the case of partial sleep deprivation, is preferred to a nap when sleepiness has to be counteracted for a longer time.     

Reactions to a black professional: motivated inhibition and activation of conflicting stereotypes

The motivation to form a particular impression of an individual can prompt the inhibition of applicable stereotypes that contradict one's desired impression and the activation and application of stereotypes that support it. Participants, especially those high in prejudice, inhibited the Black stereotype when motivated to esteem a Black individual (because he had praised them). Participants motivated to esteem a Black doctor also activated the doctor stereotype. In contrast, participants motivated to disparage a Black doctor (because he had criticized them) inhibited the doctor stereotype. Participants motivated to disparage a Black individual also applied the Black stereotype to him, rating him as relatively incompetent. All these effects were driven by the self-protective motives of recipients of feedback from Black evaluators; detached observers showed no such effects.     

Adrenocortical reactivity and social competence in seven year-olds

We examined temporal changes in salivary cortisol in response to a peer self-presentation task in a group of seven year-olds, some of whom scored high, average, and low on the Harter, 1983 Perceived Social Competence Scale. Salivary cortisol was measured pre-task, and 20 and 35 min post-task. We found a significant relation between individual differences in perceived social competence and salivary cortisol reactivity in response to the task. Children who perceived themselves as socially competent exhibited a significantly greater decrease in salivary cortisol from 20 to 35 min following the task compared with children who self-reported a relatively lower degree of social competence. We speculate on the meaning of salivary cortisol changes in childrens socio-emotional development.     

Risk of sexual revictimization: A theoretical model

Survivors of child sexual abuse suffer serious short- and long-term psychological consequences. Sexual revictimization as an adult is one of the consequences that has been reported. At present, there is no theoretical model identifying the risk factors that result in child sexual abuse survivors being at greater risk of experiencing an adult sexual assault. The proposed model is designed to integrate existing research, stimulate further empirical work, and eventually aid in the development of a program to prevent revictimization. The variables hypothesized to play a mediating role in the pathway to revictimization include: severe psychological symptoms as a consequence of the child sexual abuse, poor coping styles, an insecure attachment style, hyperfemininity, delinquent behavior, drug use, and high risk sexual behavior.     

A computer-graphic technique for the study of body size perception and body types

We present a novel approach for measuring body size estimation in normal and eating-disordered women and men. Clinical categories of body types were used as prototypes. By comparing the subjective appearance of a person’s body with prototypes, we can understand how different attributes of his or her body shape contribute to perception of body size. After lifelike random distortions have been applied to parts of their body image, individuals adjust their body shapes until they converge on their perceived veridical appearance. Exaggeration and minimization of particular body areas measured with respect to their true shape and with different prototypes can be expressed as numerical deviations. In this way, perceived body size and body attractiveness can be appraised during the course of diagnosis and treatment of eating disorders.     

Otto Rank's Conception of the Will

Rank is the only psychoanalyst to introduce the concept of will as central to an understanding of human psychology. The function of willing and the clear uniqueness of each individual challenge the causal, deterministic thinking of Freudian psychoanalysis and thereby the predictability of behavior. Thus, for the individual will means choice, and therefore moral responsibility for one's own acts. It also means the opportunity to create the new. The very formation of the individual self as it separates and differentiates itself from the maternal matrix is a creative act—one which inevitably precipitates a certain, but normally manageable, amount of guilt because of empathic feelings for the one who has been left—originally the mother. Beyond the creation of self, the will, through its creative role, helps to allay the inevitable human fear of the final separation, namely death by producing those manifestations of civilization—art, literature, music, and science—which in their generative capacity insure immortality.     

Correlates of Satisfaction with a Peer Evaluation System: Investigation of Performance Levels and Individual Differences

The present research examined the effects of performance level and individual differences on participants' satisfaction with a peer evaluation system. One hundred and fifty-three individuals working in groups completed a questionnaire assessing self-monitoring, self-esteem, and individualism. A peer evaluation system was used at the end of the project. Subjects indicated their satisfaction with and reaction to the peer evaluation system. The findings demonstrated that performance level, individualism, self-esteem, and self-monitoring helped to understand and to predict group members' reactions to the peer evaluation system. Implications for future research and implementation of peer rating systems are discussed.
