Subliminal priming of winning images prompts increased betting in slot machine play

In 2 experiments (n = 327), participants played a computerized slot machine game. Some participants had the jackpot symbols repeatedly flashed for 30 ms during preliminary play. Exposure to the subliminal jackpot prime led to more betting and confidence on a final spin. In Experiment 2, this effect only occurred for those who placed their bets immediately following exposure to the primes. Betting and confidence returned to baseline levels if participants were forced to wait for 5 minutes before betting. This finding supports a category priming explanation rather than a goal activation explanation for the effect. Results are discussed in the context of research on subliminal priming, and as an example of an application of subliminal priming effects to consumer psychology.     

The Development of the Conceptual Organization of Self

This study posed a cognitive-differentiation hypothesis for the development of the concept of self. Children from kindergarten through sixth grade (N = 112), divided equally between the sexes, were administered a class-inclusion task and two measures of the concept of self. The Imaginary Audience Scale for the Young Child (IAS; Elkind & Bowen, 1979) indexed two aspects of the Jamesian “I,” or self-as-subject. A newly developed instrument, the Part-of-Me Scale (PMS), measured the various constituents of the Jamesian “me,” or self-as-object. The results indicated a sex difference on the IAS subscales and a grade effect for constituents judged as integral to self-definition. The results suggest that a relational concept of self, characterized by individuation from and integration with the external world, may be a developmental achievement not apparent until middle adolescence.     

Transfer of Motor Learning Engages Specific Neural Substrates During Motor Memory Consolidation Dependent on the Practice Structure

The authors investigated how brain activity during motor-memory consolidation contributes to transfer of learning to novel versions of a motor skill following distinct practice structures. They used 1 Hz repetitive Transcranial Magnetic Stimulation (rTMS) immediately after constant or variable practice of an arm movement skill to interfere with primary motor cortex (M1) or dorsolateral prefrontal cortex (DLPFC). The effect of interference was assessed through skill performance on two transfer targets: one within and one outside the range of practiced movement parameters for the variable practice group. For the control (no rTMS) group, variable practice benefited delayed transfer performance more than constant practice. The rTMS effect on delayed transfer performance differed for the two transfer targets. For the within-range target, rTMS interference had no significant affect on the delayed transfer after either practice structure. However, for the outside-range target, rTMS interference to DLPFC but not M1 attenuated delayed transfer benefit following variable practice. Additionally, for the outside-range target, rTMS interference to M1 but not DLPFC attenuated delayed transfer following constant practice. This suggests that variable practice may promote reliance on DLPFC for memory consolidation associated with outside-range transfer of learning, whereas constant practice may promote reliance on M1 for consolidation and long-term transfer.     

Assessing Interpersonal Aspects of Schizoid Personality Disorder: Preliminary Validation Studies

In 2 studies, we examined the reliability and validity of an interpersonal measure of schizoid personality disorder (SZPD) based on nonverbal behaviors and interpersonal interactions occurring during interviews. A total of 556 male jail inmates in the United States participated in Study 1; 175 mentally disordered offenders in maximum security hospitals in the United Kingdom participated in Study 2. Across both samples, scores on the Interpersonal Measure of Schizoid Personality Disorder (IM–SZ) exhibited adequate reliability and patterns of correlations with other measures consistent with expectations. The scale displayed patterns of relatively specific correlations with interview and self-report measures of SZPD. In addition, the IM–SZ correlated in an expected manner with features of psychopathy and antisocial personality and with independent ratings of interpersonal behavior. We address implications for assessment of personality disorder.     

Psychometric Properties and Norms for the Personality Assessment Inventory in Egg Donors and Gestational Carriers

Although psychological evaluations are an integral element of screening for third-party reproduction and the Personality Assessment Inventory (PAI) is commonly used for these evaluations, little is known about the psychometric properties or normative scores on the PAI among egg donors and carriers. We evaluated the PAI among 1,044 egg donors and gestational carriers from various fertility clinics across the United States. PAI scales were generally internally consistent in this population, although range restriction appeared to attenuate reliability on several scales. The PAI profiles of egg donors and carriers had elevated positive impression management and suppressed clinical scale scores relative to the community standardization sample, as would be expected given the contingencies of this assessment context. Scores were similar across egg donors and carriers and were similar whether the carrier or donor was known or not known to the prospective parents. Sample-specific norms are provided for the use of the PAI in this setting.     

Group Treatment of Sexually Abused Adolescent Girls: A Review of Outcome Studies

Abstract

This paper considers factors that make children “at risk” for postdivorce maladjustment. The risk factors include (a) demographic variables of sex, age and socioeconomic status; (b) predivorce family functioning; (c) postdivorce relationship with the ex-spouse; (d) postdivorce parentchild interaction; and (e) social support systems. Treatment programs incorporating these factors are briefly described. Recommendations are provided for the clinician and researcher.     

The Use of a Socially Constructed Genogram in Clinical Practice

This paper discusses the rationale for a socially constructed genogram, allowing for multiple definitions of family to be represented. It describes the role of the problem system and the utility of this genogram in these situations. It describes the set-up of a socially constructed genogram and provides clinical examples.     

Heart Rate and Affective Reactions to State Self-Objectification as a Function of Gender

The purpose of the present study was to examine heart rate (HR) and affective reactions to state self-objectification as a function of gender. We examined negative affect, positive affect, guilt, and HR at 6-second and 5-minute intervals across baseline, control, high objectification, low objectification, and cologne conditions in men (n = 53) and women (n = 57). Mixed factorial MANOVA results indicated a statistically significant Gender × Condition interaction. Both men and women showed a cardiac orienting response to high versus low objectification. Cardiac stress reactions to objectification were higher among women. Negative affective reactions to objectification were more pervasive across conditions among women.
