Aging, metamemory, and high-confidence errors: a misrecollection account

Two experiments showed that older adults were worse than younger adults at judging the accuracy of their responses on source identification (i.e., who said what) and cued-recall tests. It is important to note that this age-related metamonitoring impairment occurred even after older and younger adults were matched on overall source accuracy and cued-recall accuracy. By contrast, older and younger adults showed comparable metamonitoring capacities when assessing the likely accuracy of old-new recognition judgments and responses to questions about general knowledge. These experiments are consistent with the misrecollection account of cognitive aging, which suggests that age-related memory impairments are due to older adults' vulnerability to making high-confidence errors when answering questions that require memory for specific details about recently learned events.     

A controlled evaluation of acceptance and commitment therapy plus habit reversal for trichotillomania

This randomized trial compared a combined Acceptance and Commitment Therapy/Habit Reversal Training (ACT/HRT) to a waitlist control in the treatment of adults with trichotillomania (TTM). Twenty-five participants (12 treatment and 13 waitlist) completed the trial. Results demonstrated a significant reduction in hair pulling severity, impairment ratings, and hairs pulled, along with significant reductions in experiential avoidance and both anxiety and depressive symptoms in the ACT/HRT group compared to the waitlist control. Reductions generally were maintained at a 3-month follow-up. Decreases in experiential avoidance and greater treatment compliance were significantly correlated with reductions in TTM severity, implying that targeting experiential avoidance may be useful in the treatment of TTM. Other implications and suggestions for future research are noted.     

An evaluation of the effectiveness of exposure and response prevention on repetitive behaviors associated with Tourette's syndrome

Exposure and response prevention (ERP) was evaluated as treatment for three repetitive behaviors in an 11-year-old boy using a multiple baseline across behaviors design. The repetitive behaviors and associated self-reported distress were eliminated. At 3-month follow-up, the frequency for two of the three behaviors returned to baseline levels. This study demonstrates that ERP may be a useful treatment for repetitive behaviors, although booster sessions may be needed to maintain the treatment effects.     

Assessing dimensions of competency to stand trial: construct validation of the ECST-R

Four decades of forensic research have left unanswered a fundamental issue regarding the best conceptualization of competency to stand trial vis-à-vis the Dusky standard. The current study investigated three competing models (discrete abilities, domains, and cognitive complexity) on combined data (N = 411) from six forensic and correctional samples. Using the Evaluation of Competency to Stand Trial-Revised (ECST-R), items representative of the Dusky prongs were used to test the three models via maximum-likelihood confirmatory factor analyses (CFA). Of the three, only the discrete abilities model evidenced a good fit, indicating that competency to stand trial should consider separately each defendant's factual understanding of the proceedings, rational understanding of the proceedings, and ability to consult with counsel. ECST-R competency scales, based on the current CFA, have excellent alphas (.83 to .89) and interrater reliabilities (.97 to .98).     

Dynamic self-efficacy and outcome expectancies: prediction of smoking lapse and relapse

According to social learning models of drug relapse, decreases in abstinence self-efficacy (ASE) and increases in positive smoking outcome expectancies (POEs) should foreshadow lapses and relapse. In this study, the authors examined this hypothesis by using ecological momentary assessment data from 305 smokers who achieved initial abstinence from smoking and monitored their smoking and their ASE and POEs by using palmtop computers. Daily ASE and POEs predicted the occurrence of a 1st lapse on the following day. Following a lapse, variations in daily ASE predicted the onset of relapse, even after controlling for concurrent smoking. ASE and POEs generally neither mediated nor moderated each other's effects. These data emphasize the role of dynamic factors in the relapse process.     

Corrections for range restriction in structured interview ethnic group differences: the values may be larger than researchers thought

Previous studies of standardized ethnic group differences in the employment interview have shown differences to be relatively small. Unfortunately, many researchers conducting interview studies have not considered the issue of range restriction in research design. This omission is likely to lead to underestimates of standardized ethnic group differences (d) when the interview is considered as an initial screening device or used in combination with other initial screening devices. The authors found that 2 forms of a behavioral interview were associated with standardized ethnic group differences of .36 and .56 when corrected for range restriction. These differences are substantially larger than previously thought and demonstrate the importance of considering a variety of study design characteristics in obtaining the appropriate parameter estimates.     

Measuring Up: Assessing the Measurement Properties of Two Self-Control Scales

Only recently has research explored patterns in the nature of violence within and across communities. Recent reports highlight the importance of both the individual characteristics and contextual environments of violent offenders, especially youth offenders. The current study examines the effects of both individual- and contextual-level characteristics on the nature of violence committed by youths as compared to adults. Specifically, we merge incident data from the National Incident Based Reporting System with contextual data on the cities in which the incidents occurred. We then use hierarchical linear modeling techniques to explore variations in predictors of offender gun use and victim injury.     

Do Boys Fight and Girls Cut? A General Strain Theory Approach to Gender and Deviance

Research finds that males are more likely to engage in delinquency than females. General strain theory (GST) suggests that males and females experience different emotions in response to strain leading to different deviant outcomes. Tests of GST to account for this issue are mixed, perhaps due to the reliance on measures that fail to take into account the gendered nature of responses to strain. The current study examines the mediation of strain by negative affect in the pathway to deviance using both a measure of externalizing deviance more commonly found among males (fighting) and a measure of internalizing deviance that is more commonly found among females (cutting oneself). Results indicate that emotions mediate some of the impact of strain on deviance and, while the path from strain to emotions is similar for boys and girls, emotions have differential effects on externalized and internalized deviance depending on sex.
