Construct Validity of the Rotter Incomplete Sentences Blank With Clinic-Referred and Nonreferred Adolescents

Inferred latent entities, whether those of psychoanalysis, factor analysis, or cluster analysis, have declined in value for many clinical psychologists, both as tools of practice and as objects of theoretical interest. Behavior modification, rational-emotive therapy, crisis intervention, psycho-pharmacology, and actuarial prediction all tend to minimize reliance on latent entities in favor of purely dispositional concepts. Behavior genetics is, however, a powerful movement to the contrary. As regards categorical entities (types, taxa, syndromes, diseases), history reveals no impressive examples of their discovery by cluster algorithms; whereas organic medicine and psychopathology have both discovered many taxonic entities without reliance on formal (statistical) cluster methods. I offer eight reasons for this strange condition, with associated suggestions for ameliorating it. Adopting a realist instead of a fictionist approach to taxonomy, I give high priority to theory-based mathematical derivation of quantitative consistency tests for all taxometric results. I urge a large scale cooperative survey of taxometric methods based on Monte Carlo runs, biological pseudoproblems where the true taxon is independently known, and live problems in genetics, organic medicine, and psychopathology. An empirical example of taxometric bootstrapping and consistency testing was presented from my own current research on schizotypy.     

On interchangeability of Nash equilibria in multi-player strategic games

The article studies properties of interchangeability of pure, mixed, strict, and strict mixed Nash equilibria. The main result is a sound and complete axiomatic system that describes properties of interchangeability in all four settings. It has been previously shown that the same axiomatic system also describes properties of independence in probability theory, nondeducibility in information flow, and non-interference in concurrency theory.     

Attachment Style and Early Maladaptive Schemas as Mediators of the Relationship between Childhood Emotional Abuse and Intimate Partner Violence

Theoretical and empirical research suggests possible pathways between women's experiences of childhood emotional abuse (CEA) and later intimate partner violence victimization (IPV-V) and perpetration (IPV-P), including attachment style and early maladaptive schemas. This study tested a model examining the unique mediating effects of insecure attachment and early maladaptive schemas on the relationship between CEA and IPV-V (n?=?396) or IPV-P (n?=?409) in college women. Contrary to hypotheses that both attachment style and maladaptive schema endorsement would mediate the relationship between CEA and IPV-V and IPV-P, regression analyses indicated the disconnection/rejection schema domain was the only significant mediator between CEA and IPV-V (p = .01). This same relation held for childhood emotional abuse and IPV-P (p < .001). These findings provide preliminary clinical utility for examining schema endorsement, the use of schema therapy (Young, Klosko, &; Weishar, 2003 Young, J. E., Klosko, J. S. and Weishar, M. E. 2003. Schema therapy: A practitioner's guide, New York: NY: Guilford.  [Google Scholar]), or both with women who have emotional abuse and IPV histories.     

Parental rearing behavior prospectively predicts adolescents’ risky decision‐making and feedback‐related electrical brain activity

The present study examined the role of parental rearing behavior in adolescents’ risky decision‐making and the brain's feedback processing mechanisms. Healthy adolescent participants (n = 110) completed the EMBU‐C, a self‐report questionnaire on perceived parental rearing behaviors between 2006 and 2008 (T1). Subsequently, after an average of 3.5 years, we assessed (a) risky decision‐making during performance of the Balloon Analogue Risk Task (BART); (b) event‐related brain potentials (ERPs) elicited by positive (gain) and negative feedback (loss) during the BART; and (c) self‐reported substance use behavior (T2). Age‐corrected regression analyses showed that parental rejection at T1 accounted for a unique and significant proportion of the variance in risk‐taking during the BART; the more adolescents perceived their parents as rejecting, the more risky decisions were made. Higher levels of perceived emotional warmth predicted increased P300 amplitudes in response to positive feedback at T2. Moreover, these larger P300 amplitudes (gain) significantly predicted risky decision‐making during the BART. Parental rearing behaviors during childhood thus seem to be significant predictors of both behavioral and electrophysiological indices of risky decision‐making in adolescence several years later. This is in keeping with the notion that environmental factors such as parental rearing are important in explaining adolescents’ risk‐taking propensities.     

Effects of cultural themes in psychotic symptoms on the diagnosis of schizophrenia in African Americans

Cultural themes focusing on race-related issues and religiosity were identified via content analysis in the delusions and hallucinations of a sample of 118 African American psychiatric patients. The purpose of the study was to determine whether cultural themes in psychotic symptoms influence the diagnosis from different sources (i.e., chart, SCID, and best estimate) of schizophrenia for Black patients. It was hypothesized that the best estimate diagnoses of cultural experts would diagnose schizophrenia in African Americans more frequently when they exhibit race-related themes in their psychotic symptoms. It was also hypothesized that diagnosis of the paranoid subtype would yield a stronger difference among the sources than the broader category of schizophrenia. The results did not support the hypotheses. Implications for understanding the relationship between culture and psychosis among African Americans are discussed.     

Social relevance enhances memory for impressions in older adults

Previous research has demonstrated that older adults have difficulty retrieving contextual material over items alone. Recent research suggests this deficit can be reduced by adding emotional context, allowing for the possibility that memory for social impressions may show less age-related decline than memory for other types of contextual information. Two studies investigated how orienting to social or self-relevant aspects of information contributed to the learning and retrieval of impressions in young and older adults. Participants encoded impressions of others in conditions varying in the use of self-reference (Experiment 1) and interpersonal meaningfulness (Experiment 2), and completed memory tasks requiring the retrieval of specific traits. For both experiments, age groups remembered similar numbers of impressions. In Experiment 1 using more self-relevant encoding contexts increased memory for impressions over orienting to stimuli in a non-social way, regardless of age. In Experiment 2 older adults had enhanced memory for impressions presented in an interpersonally meaningful relative to a personally irrelevant way, whereas young adults were unaffected by this manipulation. The results provide evidence that increasing social relevance ameliorates age differences in memory for impressions, and enhances older adults’ ability to successfully retrieve contextual information.     

Work Stressors,Depressive Symptoms,and Hazardous Drinking Among Navy Members Across Deployment

Few studies have attempted to examine how changes in work stressors from predeployment to postdeployment and reintegration may be associated with changes in mental health symptoms and hazardous drinking. The present study examined associations between work stressors, depressive symptoms, and hazardous drinking, and whether depressive symptoms mediated the association between work stressors and hazardous alcohol use or vice versa across deployment (predeployment, postdeployment, and 6-month reintegration). Participants were 101 U.S. Navy members (72 men; mean age = 28.34 years; SD = 5.99 years) assigned to an Arleigh Burke-class destroyer that experienced an 8-month deployment after recent wars in the Middle East. They completed measures that assessed work stressors, depressive symptoms, and alcohol use at each time point (i.e., predeployment, postdeployment, and 6-month reintegration). Using a parallel process latent growth modeling approach, we found a significant indirect effect at postdeployment such that an increase in work stressors contributed to increases in hazardous drinking via increases in depressive symptoms. Specifically, increases in work stressors significantly predicted increases in depressive symptoms, which in turn significantly predicted increases in hazardous drinking from pre- to postdeployment. Our findings garner support for affect regulation models and indicate that work stressors and changes in work stressors and depressive symptoms may be key to hazardous alcohol use among U.S. Navy members experiencing high pace of deployment. Taken together, our results help identify targets for alcohol prevention efforts among current military members.     

Similarities and differences between mind-wandering and external distraction: A latent variable analysis of lapses of attention and their relation to cognitive abilities

The current study examined the extent to which task-unrelated thoughts represent both vulnerability to mind-wandering and susceptibility to external distraction from an individual difference perspective. Participants performed multiple measures of attention control, working memory capacity, and fluid intelligence. Task-unrelated thoughts were assessed using thought probes during the attention control tasks. Using latent variable techniques, the results suggested that mind-wandering and external distraction reflect distinct, yet correlated constructs, both of which are related to working memory capacity and fluid intelligence. Furthermore, the results suggest that the common variance shared by mind-wandering, external distraction, and attention control is what primarily accounts for their relation with working memory capacity and fluid intelligence. These results support the notion that lapses of attention are strongly related to cognitive abilities.
