Joint Influence of Visual and Auditory Words in the Stroop Task

We conducted four Stroop color–word experiments to examine how multiple stimuli influence interference. Experiments 1a and 1b showed that interference was strong when the word and color were integrated, and that visual and auditory words made independent contributions to interference when these words had different meanings. Experiments 2 and 3 confirmed this pattern when the word information and color information were not integrated, and hence when overall interference was substantially less. Auditory and visual interference effects are comparable except when the visual distracter is integrated with the color, in which case interference is substantially enhanced. Overall, these results are interpreted as being most consistent with a joint influence account of interference as opposed to a capture account.     

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior

Sex differences in the genetic and environmental influences on childhood conduct disorder and adult antisocial behavior were examined in a large community sample of 6,383 adult male, female, and opposite-sex twins. Retrospective reports of childhood conduct disorder (prior to 18 years of age) were obtained when participants were approximately 30 years old, and lifetime reports of adult antisocial behavior (antisocial behavior after 17 years of age) were obtained 8 years later. Results revealed that either the genetic or the shared environmental factors influencing childhood conduct disorder differed for males and females (i.e., a qualitative sex difference), but by adulthood, these sex-specific influences on antisocial behavior were no longer apparent. Further, genetic and environmental influences accounted for proportionally the same amount of variance in antisocial behavior for males and females in childhood and adulthood (i.e., there were no quantitative sex differences). Additionally, the stability of antisocial behavior from childhood to adulthood was slightly greater for males than females. Though familial factors accounted for more of the stability of antisocial behavior for males than females, genetic factors accounted for the majority of the covariation between childhood conduct disorder and adult antisocial behavior for both sexes. The genetic influences on adult antisocial behavior overlapped completely with the genetic influences on childhood conduct disorder for both males and females. Implications for future twin and molecular genetic studies are discussed.     

Disordered gambling as defined by the Diagnostic and Statistical Manual of Mental Disorders and the South Oaks Gambling Screen: evidence for a common etiologic structure

In a previous article, we demonstrated in a large twin study that disordered gambling (DG), as defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV), ran in families, that about half of the variation in liability for DG was due to familial factors, and that all of this was explained by shared genetic rather than shared environmental influences (Slutske, Zhu, Meier, & Martin, 2010). The purpose of the present study is to extend this work to include an alternative conceptualization of DG that is provided by the South Oaks Gambling Screen (SOGS) item set in order to (a) compare the magnitude of the familial resemblance obtained when using the two definitions of DG (based on the DSM-IV and the SOGS), (b) examine the extent to which the 2 definitions tap the same underlying sources of genetic and environmental variation, and (c) examine whether the same results will be obtained among men and women. The results of bivariate twin model-fitting analyses suggested that DG, as defined by the DSM-IV and the SOGS, substantially overlapped at the etiologic level among both men and women, which supports the construct validity of both the DSM and the SOGS conceptualizations of DG. This study highlights the utility of twin studies for appraising the validity of the diagnostic nomenclature.     

Developmental origins of perfectionism among African American youth

The present study used a person-centered latent variable approach to classify types of perfectionism among 6th-grade African American children living in an urban setting. In particular, the authors were interested in determining whether an adaptive subtype could be found and validated against external criteria. The authors also attempted to identify any developmental precursors that could reliably differentiate the perfectionist subtypes. A social learning and competence framework was used to select potential 1st-grade risk and protective factors for future perfectionism profiles. Four classes best described the children's perfectionism scores in 6th grade. Three of these classes resembled the profiles most commonly seen in prior perfectionism research (Non-Critical/Adaptive, Critical/Maladaptive, and Non-Perfectionist). The fourth class, Non-Striving, was characterized by extremely low levels of reported personal standards. Sixth-grade correlates confirmed the distinctiveness of these classes. In particular, the Critical/Maladaptive and Non-Striving classes had higher rates of internalizing symptoms and disorders. Additionally, several 1st-grade predictors suggested unique developmental origins of these classes. The Critical/Maladaptive class was characterized by lower academic skills and elevated teacher-rated attention problems, hyperactivity, shyness, and peer rejection. The Non-Striving class had higher rates of family alcohol problems and lower levels of parent praise. Implications regarding the universal and culture-specific origins and effects of perfectionism are discussed.     

What Do Chaplains Contribute to Large Academic Hospitals? The Perspectives of Pediatric Physicians and Chaplains

This article analyzes interviews with pediatric physicians (N = 30) and chaplains (N = 22) who work at the same large academic medical centers (N = 13). We ask how pediatric physicians understand and work with chaplains and how chaplains describe their own work. We find that physicians see chaplains as part of interdisciplinary medical teams where they perform rituals and support patients and families, especially around death. Chaplains agree but frame their contributions in terms of the perspectives related to wholeness, presence, and healing they bring. Chaplains have a broader sense of what they contribute to patient care than do physicians.     

The pull of the past: when do habits persist despite conflict with motives?

To identify the factors that disrupt and maintain habit performance, two field experiments tested the conditions under which people eat out of habit, leading them to resist motivational influences. Habitual popcorn eaters at a cinema were minimally influenced by their hunger or how much they liked the food, and they ate equal amounts of stale and fresh popcorn. Yet, mechanisms of automaticity influenced habit performance: Participants ate out of habit, regardless of freshness, only when currently in the context associated with past performance (i.e., a cinema; Study 1) and only when eating in a way that allowed them to automatically execute the response cued by that context (i.e., eating with their dominant hand; Study 2). Across all conditions, participants with weaker cinema-popcorn-eating habits ate because of motivations such as liking for the popcorn. The findings reveal how habits resist conflicting motives and provide insight into promising mechanisms of habit change.     

The impact of adopting ethnic or civic conceptions of national belonging for others' treatment

National belonging is often defined in terms of "ethnic" ancestry and "civic" commitment (with the latter typically implying a more inclusive conception of belonging). The authors report three Scottish studies manipulating the prominence of these criteria. In Study 1 (N = 80), a Chinese-heritage target was judged more Scottish (and his criticisms of Scotland better received) when Scotland was defined in civic terms. In Study 2 (N = 40), a similar manipulation in a naturalistic setting showed a civic conception of belonging resulted in more help being given to a Chinese-heritage confederate. Study 3 (N = 71) replicated Study 2 and showed the effect was mediated by judgments of the confederate's Scottishness. These studies emphasize the importance of exploring how ingroup identity is defined.     

Hope as a Mediator and Moderator of Multidimensional Perfectionism and Depression in Middle School Students

The authors examined the relationship of perfectionism, hope, and depression in a sample of 153 middle school students. Adaptive perfectionists differed significantly from both maladaptive perfectionists and nonperfectionists on their levels of hope and depression. Hope mediated the relationship between maladaptive perfectionism and depression and supported an indirect effects model for hope and the relationship between adaptive perfectionism and depression. No evidence was found for hope as a moderator in the relationship between perfectionism and depression.     

What do Non-clergy Spiritual Care Providers Contribute to End of Life Care in Israel? A Qualitative Study

Spiritual care is an increasingly important component of end of life care. As it emerges in Israel, it is intentionally built on a nonclerical model. Based on interviews with spiritual care providers in Israel, we find that they help patients and families talk about death and say goodbyes. They encourage the wrapping up of unfinished business, offer diverse cultural resources that can provide meaning, and use presence and touch to produce connection. As spiritual care emerges in Israel, providers are working with patients at the end of life in ways they see as quite distinct from rabbis. They offer broad frames of meaning to which patients from a range of religious traditions can connect.
