Response Interruption and Differential Reinforcement of Alternative Behavior for the Treatment of Pica

Pica displayed by two individuals with autism was decreased by a treatment involving differential reinforcement and response interruption that altered the chain of behavior involved in pica (i.e., picking up items and placing them in the mouth). The treatment involved establishing prompts to ‘clean‐up’ as a new discriminative stimulus (SD) for picking up items from the floor; and holding potential pica items was established as an SD for discarding those items in a trash receptacle, putting them away, or using them appropriately. After demonstrating the effectiveness of the treatment in an analog setting, the treatment package was systematically generalized to community settings. Copyright © 2011 John Wiley & Sons, Ltd.     

The impact of depressive symptomatology on risky sexual behavior and sexual communication among African American female adolescents

Adolescents, particularly African American adolescents, are at high risk for sexually transmitted infections (STIs). The association between psychosocial factors and risky sexual behavior has been well established. However, only a small number of studies have examined the relationship between depressive symptomatology among African American female adolescents, specifically over time. The present study examined depressive symptoms as a predictor of risky sexual behavior, sexual communication, and STIs longitudinally among African American female adolescents between the ages 15 and 21. Binary generalized estimating equation models were conducted assessing the impact of depressive symptoms at baseline on risky sexual behavior and STIs over six- and 12-months follow-up. Age, intervention group, and baseline outcome measures were entered as covariates. The results indicated that high levels of depressive symptoms predicted no condom use during last sexual encounter and multiple sexual partners over six-months follow-up. Depressive symptoms also predicted having a main partner with concurrent partners, high fear of communication about condoms, and sex while high on alcohol or drugs over six- and 12-months follow-up. These findings could be used to inform HIV/STI prevention intervention programs and clinicians providing regular health care maintenance to African American female adolescents engaging in risky sexual behavior.     

A twin study of spatial and non-spatial delayed response performance in middle age

Delayed alternation and object alternation are classic spatial and non-spatial delayed response tasks. We tested 632 middle-aged male veteran twins on variants of these tasks in order to compare test difficulty, measure their inter-correlation, test order effects, and estimate heritabilities (proportion of observed variance due to genetic influences). Non-spatial alternation (NSA), which may involve greater reliance on processing of subgoals, was significantly more difficult than spatial alternation (SA). Despite their similarities, NSA and SA scores were uncorrelated. NSA performance was worse when administered second; there was no SA order effect. NSA scores were modestly heritable (h(2)=.25; 26); SA was not. There was shared genetic variance between NSA scores and general intellectual ability (r(g)=.55; .67), but this also suggests genetic influences specific to NSA. Compared with findings from small, selected control samples, high "failure" rates in this community-based sample raise concerns about interpretation of brain dysfunction in elderly or patient samples.     

Leader‐driven distortion of probability and payoff information affects choices between risky prospects

Research indicating that decision makers often distort new information to favor nascent preferences has focused primarily on riskless choice rather than risky choice. In addition, the critical assumption that information distortion mediates the link between the initially preferred alternative and the final choice has not been tested in a compelling manner. In an experiment designed to fill these gaps, participants made six choices involving pairs of hypothetical three‐outcome monetary gambles. We manipulated initial preferences by varying the order in which gamble features were presented. Multilevel regressions indicated that participants distorted their evaluations of precise probabilities and payoffs in the direction of their emerging preferences and that they used their biased evaluations to update those preferences. As expected, information distortion mediated the effect of initial preferences on final choices and final preference strength. In a follow‐up experiment, we compared a standard measure of information distortion (based on comparisons to mean ratings in a no‐choice control task) to a more personalized measure (based on participants' own ratings in the control task) and found the mean‐based measure to be superior for the probability and payoff information in question. Other findings in Experiment 2 corroborated the results of Experiment 1. In both studies, the distortion of quantitative inputs in a simple task highlights the non‐normative circularity of the choice process. Copyright © 2010 John Wiley & Sons, Ltd.     

Further evidence of the Narcissistic Personality Inventory’s validity problems: A meta-analytic investigation—Response to Miller, Maples, and Campbell (this issue)

Miller, Maples, and Campbell (this issue) present evidence that Rosenthal and Hooley’s (2010) concerns regarding the Narcissistic Personality Inventory’s (NPI) relation to psychological health may be unwarranted. To resolve this issue empirically, we conducted a meta-analysis (k = 54, N = 38,932). Meta-analytic results revealed that a subset of NPI items were indeed problematic; items that function poorly at differentiating narcissists from non-narcissists accounted entirely for the NPI’s connection to psychological health. These items were also strongly associated with self-esteem, but unrelated to aggression/anger. In contrast, the remaining NPI items were unrelated to psychological health, but associated with aggression/anger. We conclude that although the NPI measures narcissism, its poorest functioning items also link it to outcomes unrelated to narcissism.     

The relationship between identity, intimacy, and midlife well-being: findings from the Rochester Adult Longitudinal Study

The present study used longitudinal data on 182 adults between the ages of 20 and 54 (104 men, 78 women) from the Rochester Adult Longitudinal Study (RALS), assessed on four occasions, to test the hypothesis that identity and intimacy during the course of early and middle adulthood predict well-being at midlife. A cross-lagged panel model was estimated yielding the following findings: (a) Scores on both scales during the college years predicted midlife satisfaction-intimacy directly, and identity through the course of development from ages 20 to 54; moreover, identity in midlife, but not intimacy, was significantly linked with well-being at this same point in time; and (b) identity and intimacy unexpectedly did not predict one another over time, having been controlled for factor stability in identity and intimacy over time. The findings are discussed in terms of Erikson's psychosocial theory of development and the developmental moments and historical cohorts that characterize the present sample.

The Path from Identity Commitments to Adjustment: Motivational Underpinnings and Mediating Mechanisms

The present study focused on motivational underpinnings of identity commitments and mediating mechanisms underlying their effects on well‐being and distress in a sample of college freshmen (N = 399). Using a path model in a structural equation modeling approach, the authors found that causality orientations appeared to serve as motivational antecedents of identity commitments. Identity integration mediated the pathway from identity commitments to adjustment (i.e., well‐being and absence of distress). Suggestions for future research and implications for counseling are provided.
