We examined how culture influences perceptions of applicant attributes when assessing employment suitability. In two studies (N = 408), we compared members from a collectivistic society (Singapore) to two samples from individualistic societies (the United States and Australia) on their perceptions of applicant attributes across job contexts. For each job, participants either chose between candidates with different attribute profiles or created ideal candidates by allocating a fixed amount of percentile points across different attributes. More often than Australians, Singaporeans chose the candidate with higher levels of the trait (e.g., openness to experience) uniquely associated with the job (e.g., graphic designer). More so than either Americans or Australians, Singaporeans prioritized having the trait most associated with each job. Members from collectivistic societies may require higher levels of the traits most associated with different jobs than members from individualistic societies, who prefer more well-rounded individuals for each job. As discussed, the study of lay perceptions may have implications for training hiring professionals and managers.     

The relational self revealed: integrative conceptualization and implications for interpersonal life

The authors offer a new, integrative conceptualization of the relational self based on a synthesis of recent approaches to the self and significant others. This conceptualization provides a sharper and fuller definition of the relational self than does any existing approach alone and a common framework to interpret findings from separate literatures. The authors then present 5 propositions and evidence to support the thesis that relational selves exert a pervasive influence on interpersonal life. Specifically, relational selves (a) shape a wide range of psychological processes and outcomes, (b) exert their influence automatically, (c) serve basic orientation and meaning functions, (d) provide continuity and context-specific variability in personality, and (e) carry implications for psychological well-being. Discussion focuses on remaining issues and implications for future research.     

Self-verification and contextualized self-views

Whereas most self-verification research has focused on people's desire to verify their global self-conceptions, the present studies examined self-verification with regard to contextualized selfviews-views of the self in particular situations and relationships. It was hypothesized that individuals whose core self-conceptions include contextualized self-views should seek to verify these self-views. In Study 1, the more individuals defined the self in dialectical terms, the more their judgments were biased in favor of verifying over nonverifying feedback about a negative, situation-specific self-view. In Study 2, consistent with research on gender differences in the importance of relationships to the self-concept, women but not men showed a similar bias toward feedback about a negative, relationship-specific self-view, a pattern not seen for global self-views. Together, the results support the notion that self-verification occurs for core self-conceptions, whatever form(s) they may take. Individual differences in self-verification and the nature of selfhood and authenticity are discussed.     

An overview on Primary Progressive Aphasia and its variants

We present a review of the literature on Primary Progressive Aphasia (PPA) together with the analysis of neuropschychological and neuroradiologic profiles of 42 PPA patients. Mesulam originally defined PPA as a progressive degenerative disorder characterized by isolated language impairment for at least two years. The most common variants of PPA are: 1) Progressive nonfluent aphasia (PNFA), 2) semantic dementia (SD), 3) logopenic progressive aphasia (LPA). PNFA is characterized by labored speech, agrammatism in production, and/or comprehension. In some cases the syndrome begins with isolated deficits in speech. SD patients typically present with loss of word and object meaning and surface dyslexia. LPA patients have word-finding difficulties, syntactically simple but accurate language output and impaired sentence comprehension. The neuropsychological data demonstrated that SD patients show the most characteristic pattern of impairment, while PNFA and LPA overlap within many cognitive domains. The neuroimaging analysis showed left perisylvian region involvement. A comprehensive cognitive, neuroimaging and pathological approach is necessary to identify the clinical and pathogenetic features of different PPA variants.     

Etiological contributions to heavy drinking from late adolescence to young adulthood

The authors examined genetic and environmental contributions to stability and change in heavy drinking from late adolescence to young adulthood in a sample of 1,152 twin pairs. In men, heavy drinking was similarly heritable at ages 17 (h2=.57) and 20 (h2=.39), and its stability owed primarily to common genetic factors. In women, heavy drinking was less heritable than in men at ages 17 (h2=.18) and 20 (h2=.30) and its stability was primarily due to enduring shared environmental influences. P3 amplitude, an event-related brain potential marker of alcoholism risk, was less predictive of heavy drinking in women than in men, providing further support for the proposition that biological factors have less impact on heavy drinking in young adult women than in young adult men.     

Psychological-state theories about significant others: implications for the content and structure of significant-other representations

Three studies tested a theory-based approach to significant-other representations. The central hypothesis was that perceivers are especially likely to possess lay theories to explain the responses of their significant others, and this is reflected in the content and structure of significant-other representations. Theories were defined in IF-THEN terms as beliefs about the psychological states (e.g., "IF Bill wants to make a good impression.") that explain others' responses (e.g., ". THEN he acts friendly"). All three studies yielded evidence indicating that the content of significant-other representations is especially likely to include such psychological-state theories (PSTs). Study 3 assessed the internal structure of PSTs-specifically, the strength of the linkages between psychological-state IFs and the THENs they are believed to elicit-and showed that such linkages are particularly strong for PSTs about significant others. Overall, the findings add to the growing literature on the role of explanatory or lay-theoretical forms of knowledge in how perceivers make sense of the social world.     

The Validity of the Child Problematic Trait Inventory in 6–12 Year Old Italian Children: Further Support and Issues of Consistency Across Different Sources of Information and Different Samples

In the present study, teacher’s ratings, mother’s ratings, and father’s ratings on the Child Problematic Trait Inventory (CPTI) were obtained on two independent samples (N?=?381 and N?=?406, respectively) of Italian school age children (age range: 6–12 years). Cronbach alpha values greater than 0.80 were observed for all CPTI scale scores based on teacher’s ratings, mother’s ratings, and father’s ratings respectively. Although intraclass correlation values suggested poor parent-teacher agreement, robust weighted least square Confirmatory Factor Analyses (WLSMV CFAs) suggested that the three-factor model of the CPTI was consistently replicated as the best fitting model across all informants. Logistic regression analysis conducted in one of the samples showed that teacher’s ratings and mother’s ratings of the CPTI, but not CPTI father’s ratings, significantly predicted child’s problem behavior at school. Multiple regression analyses showed that CPTI scores were significantly predicted by selected temperament dimensions, but with different relationships for different sources of information. Overall, our findings suggest that the CPTI is a reliable and valid measure of problematic traits with a three-factor structure, although this study indicates that multiple sources of information may prove necessary when assessing psychopathy in school-age children with the CPTI.     

Multiple racial identities as sources of psychological resilience

Much of the research on multiracial individuals has focused on the impact of a multiracial background on psychological well‐being. This work, often using clinical samples, identified a higher prevalence of negative psychological outcomes among multiracial individuals, such as low self‐esteem, poor grades, or self‐hatred, and has emphasized that these negative outcomes stem from the unique challenges associated with navigating multiple racial identities. However, research on nonclinical samples finds that multiracial individuals fare as well as monoracial individuals on these, and other, outcomes. We put forth a synthesizing theory aimed at understanding how multiracial individuals develop adaptive coping strategies, which help them learn to navigate multiple identities and maintain positive psychological outcomes. In the current contribution, we build on existing research to theorize that multiracial individuals can engage in two psychological strategies that increase resilience: (a) switching between multiple racial identities and (b) reduced essentializing of race. Evidence and consequences of these two strategies are discussed. Taken together, in contrast to traditional depletion models of coping, this work highlights the unique experience of multiracial individuals and the potential psychological benefits of belonging to multiple racial groups in a racialized world.     

Musical expertise has minimal impact on dual task performance

Studies investigating effect of practice on dual task performance have yielded conflicting findings, thus supporting different theoretical accounts about the organisation of attentional resources when tasks are performed simultaneously. Because practice has been proven to reduce the demand of attention for the trained task, the impact of long-lasting training on one task is an ideal way to better understand the mechanisms underlying dual task decline in performance. Our study compared performance during dual task execution in expert musicians compared to controls with little if any musical experience. Participants performed a music recognition task and a visuo-spatial task separately (single task) or simultaneously (dual task). Both groups showed a significant but similar performance decline during dual tasks. In addition, the two groups showed a similar decline of dual task performance during encoding and retrieval of the musical information, mainly attributed to a decline in sensitivity. Our results suggest that attention during dual tasks is similarly distributed by expert and non-experts. These findings are in line with previous studies showing a lack of sensitivity to difficulty and lack of practice effect during dual tasks, supporting the idea that different tasks may rely on different and not-sharable attentional resources.
