What is so special about male adolescent sexual offending? A review and test of explanations through meta-analysis.

We tested special and general explanations of male adolescent sexual offending by conducting a meta-analysis of 59 independent studies comparing male adolescent sex offenders (n = 3,855) with male adolescent non-sex offenders (n = 13,393) on theoretically derived variables reflecting general delinquency risk factors (antisocial tendencies), childhood abuse, exposure to violence, family problems, interpersonal problems, sexuality, psychopathology, and cognitive abilities. The results did not support the notion that adolescent sexual offending can be parsimoniously explained as a simple manifestation of general antisocial tendencies. Adolescent sex offenders had much less extensive criminal histories, fewer antisocial peers, and fewer substance use problems compared with non-sex offenders. Special explanations suggesting a role for sexual abuse history, exposure to sexual violence, other abuse or neglect, social isolation, early exposure to sex or pornography, atypical sexual interests, anxiety, and low self-esteem received support. Explanations focusing on attitudes and beliefs about women or sexual offending, family communication problems or poor parent–child attachment, exposure to nonsexual violence, social incompetence, conventional sexual experience, and low intelligence were not supported. Ranked by effect size, the largest group difference was obtained for atypical sexual interests, followed by sexual abuse history, and, in turn, criminal history, antisocial associations, and substance abuse. We discuss the implications of the findings for theory development, as well as for the assessment, treatment, and prevention of adolescent sexual offending.

Does human capital matter? A meta-analysis of the relationship between human capital and firm performance.

Theory at both the micro and macro level predicts that investments in superior human capital generate better firm-level performance. However, human capital takes time and money to develop or acquire, which potentially offsets its positive benefits. Indeed, extant tests appear equivocal regarding its impact. To clarify what is known, we meta-analyzed effects drawn from 66 studies of the human capital–firm performance relationship and investigated 3 moderators suggested by resource-based theory. We found that human capital relates strongly to performance, especially when the human capital in question is not readily tradable in labor markets and when researchers use operational performance measures that are not subject to profit appropriation. Our results suggest that managers should invest in programs that increase and retain firm-specific human capital. (PsycINFO Database Record (c) 2011 APA, all rights reserved)     

Are health and happiness the product of wisdom? The relationship of general mental ability to educational and occupational attainment, health, and well-being.

This study tested a structural model explaining the effects of general mental ability on economic, physical, and subjective well-being. A model was proposed that linked general mental ability to well-being using education, unhealthy behaviors (smoking and excessive drinking), occupational prestige, and health as mediating variables. The sample consisted of 398 individuals, from whom measures were collected across 4 periods. The results supported a model that includes direct and indirect (through unhealthy behaviors and occupational prestige) links from mental ability to physical well-being (i.e., health) and economic well-being. Furthermore, the results supported the relationships of economic well-being and physical well-being to subjective well-being. Overall, the study underscores the importance of general mental ability to work and nonwork outcomes, including physical, economic, and psychological well-being.

What explains the relationship between the therapist structure × patient reactance interaction and drinking outcome? An examination of potential mediators.

Recent research found that among patients in aftercare treatment for alcoholism the level of therapist structure interacted with the level of patients' interpersonal reactance to predict alcohol use outcomes. The present study examined two sets of potential mediators of this interaction effect among a sample from two aftercare sites of Project MATCH (n = 127). The mediator constructs were types of pro-recovery change talk and resistance to therapeutic work. Dependent variables were percentage of days abstinent (PDA) and percentage of heavy drinking days (PHDD) across the year after treatment. Multiple-mediator models using bootstrapped estimates of indirect effects were used to test for mediation. Results indicated that the 'taking steps' aspect of change talk partially mediated the Structure × Reactance interaction effect on both PDA and PHDD post treatment. Resistance was not found to mediate the interaction effect though resistance did predict worse drinking outcomes. Depending on patients' openness to being influenced by others, therapist structure early in treatment may promote or inhibit pro-recovery steps taken by aftercare patients between treatment sessions. Those steps in turn play an important role in predicting future alcohol use. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Reasoning rats or associative animals? A common-element analysis of the effects of additive and subadditive pretraining on blocking.

Beckers, Miller, De Houwer, and Urushihara (2006) described the results of 3 blocking experiments conducted with rats. Beckers et al. concluded that the results of these experiments cannot be accounted for with existing theories of associative learning, and argued, instead, that the results were a consequence of the rats engaging in a process akin to effortful reasoning. Simulations of the Rescorla and Wagner (1972) theory of learning presented here challenge this conclusion by providing an alternative, associative, explanation for the results presented by Beckers et al.

Do mastery approach goals and research outcome expectations mediate the relationship between the research training environment and research interest? Test of a social cognitive model.

The conduct of research is inherently an achievement-oriented process, yet little research has examined the role of achievement motives relative to important research-relevant outcomes. The present study examined the role of mastery approach goals as potential mediators of the relations between the research training environment (RTE) on one hand, and research outcome expectations and research interest on the other. Participants consisted of 217 doctoral students in counseling psychology. Structural equation modeling with maximum likelihood estimation was used to test the mediational hypotheses. Results of χ2 difference testing indicated that both mastery approach goals and research outcome expectations mediated the relationship between the RTE and research interest. Sobel tests of indirect effect further indicated that (a) mastery approach goals mediated the relationship between the RTE and research outcome expectations, and (b) research outcome expectations mediated the relationship between mastery approach goals and research interest. Practical and theoretical implications for research training are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

From the American Psychological Association to the American Psychology Association--An organization for psychologists or for the discipline? 2007 annual report of the APA Policy and Planning Board.

Each year, the American Psychological Association's Policy and Planning Board takes the pulse of the Association and the discipline as a whole and writes a report that represents the Board's best appraisal of a fundamental policy. Our main objective, however, is not simply to assess the current situation but to look forward on behalf of the Association and our membership. In 2007, the Policy and Planning Board examined APA's mission in the context of a changing professional and scholarly environment. This report thus explores alternative visions of a future American Psychological Association and takes on the ambitious task of rethinking the Association's mission and how the American Psychological Association might best serve its members, the discipline, and society. In this article, we envision the promise of rethinking the American Psychological Association's mission in the profession and in society. We discuss the American Psychological Association's function and identity and then introduce a conceptual framework that would move us toward becoming the American Psychology Association to promote the work of "psychology." We then proceed to outline the benefits and pitfalls of such a change in mission, as well as some practical and ideological barriers that might block such change. We conclude by summarizing our thought experiment and identifying avenues for productive discussion. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Less power or powerless? Egocentric empathy gaps and the irony of having little versus no power in social decision making.

The authors investigate the effect of power differences and associated expectations in social decision making. Using a modified ultimatum game, the authors show that allocators lower their offers to recipients when the power difference shifts in favor of the allocator. Remarkably, however, when recipients are completely powerless, offers increase. This effect is mediated by a change in framing of the situation: When the opponent is without power, feelings of social responsibility are evoked. On the recipient side, the authors show that recipients do not anticipate these higher outcomes resulting from powerlessness. They prefer more power over less, expecting higher outcomes when they are more powerful, especially when less power entails powerlessness. Results are discussed in relation to empathy gaps and social responsibility. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Catching up or falling behind? Initial English proficiency, concentrated poverty, and the reading growth of language minority learners in the United States.

This study contrasts growth trajectories in English reading for 2 groups of language minority (LM) learners--those who enter kindergarten with limited oral English proficiency and those who enter kindergarten proficient in oral English--with that of native English speakers. Fitting a multilevel model for change to longitudinal data on a nationally representative sample, this study examines students' growth trajectories from kindergarten through 5th grade. Three noteworthy findings emerge. First, LM learners entering kindergarten proficient in English have trajectories similar to those of native English speakers, but LM learners entering kindergarten with limited English have trajectories that diverge from those of native English speakers, yielding large differences in achievement by the 5th grade. Second, controlling for demographic risk factors, including socioeconomic status (SES), reduces the effect of initial English proficiency from large to moderate and yields differences that narrow over time. Finally, these differences depend on school poverty, with smaller differences evident among students in high-poverty schools than among students in low-poverty schools. Results emphasize the need for academic interventions for LM learners who enter school with limited English proficiency. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

To transfer or not to transfer? Investigating the combined effects of trainee characteristics, team leader support, and team climate.

Eighty pilots participated in a study of variables influencing the transfer process. Posttraining performance was assessed in a flight simulation under 1 of 2 conditions. Those in the maximum performance condition were made aware of the skill to be assessed and the fact that their teammates were confederates, whereas those in the typical performance condition were not. The results indicated that (a) simulator ratings correlated with a measure of transfer to the cockpit for those in the typical condition only; (b) team leader support, manipulated in a pretask brief, moderated the disparity between maximum and typical performance; (c) team climate mediated the impact of support on performance in the typical condition; (d) those with a stronger predisposition toward the trained skill viewed their climate as more supportive; and (e) perceptions of team climate were better predictors of performance for those with a more external locus of control.

The Ninth Circuit Court's treatment of the history of suicide by Ancient Jews and Christians in Compassion in Dying v. State of Washington: historical naivete or special pleading?

In this article, Prof. Darrel Amundsen critiques Judge Reinhardt's comments regarding "Historical Attitudes Toward Suicide" in his Compassion in Dying opinion. Amundsen demonstrates that the court's characterization of ancient Jewish and Christian practices is inaccurate and misleading because it fails to acknowledge the complexities of the moral issue of suicide. Amundsen discusses martyrdom, suicide in general, suicide by the ill, and euthanasia in ancient Judaism. In contrast to the court's commentary, Amundsen demonstrates that regard for human life is a central feature of Jewish ethical monotheism. Furthermore, the author challenges the court's conclusions about early Christianity, and explains why its treatment of the issue of suicide in early Christianity is misleading and inaccurate. Amundsen's discussion of early Christianity includes suicide, martyrdom, and especially the Augustinian teaching on suicide. He concludes that the court's treatment of the issue of suicide in early Christianity is so historically and conceptually muddled as to be fundamentally inaccurate.     

Does contact reduce prejudice or does prejudice reduce contact? A longitudinal test of the contact hypothesis among majority and minority groups in three european countries.

A widely researched panacea for reducing intergroup prejudice is the contact hypothesis. However, few longitudinal studies can shed light on the direction of causal processes: from contact to prejudice reduction (contact effects) or from prejudice to contact reduction (prejudice effects). The authors conducted a longitudinal field survey in Germany, Belgium, and England with school students. The sample comprised members of both ethnic minorities (n = 512) and ethnic majorities (n = 1,143). Path analyses yielded both lagged contact effects and prejudice effects: Contact reduced prejudice, but prejudice also reduced contact. Furthermore, contact effects were negligible for minority members. These effects were obtained for 2 indicators of prejudice: negative intergroup emotions and desire for social distance. For both majority and minority members, contact effects on negative emotions were stronger when outgroup contacts were perceived as being typical of their group. Contact effects were also mediated by intergroup anxiety. This mediating mechanism was impaired for minority members because of a weakened effect of anxiety on desire for social distance. Theoretical and practical implications of these findings are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Can the influence of childhood socioeconomic status on men’s and women’s adult body mass be explained by adult socioeconomic status or personality? Findings from a national sample.

Objectives: On the basis of a life-course risk-chain framework, the authors examined whether (a) residual associations between childhood socioeconomic status (SES) and adult obesity and body mass index (BMI) would be observed in women but not men after adjusting for adult SES, (b) adult Big Five personality traits would be associated with adult body mass in both genders, and (c) personality would explain unique variation in outcomes beyond child and adult SES. Design: National survey (Midlife Development in the United States study; N = 2,922). Main Outcome Measures: BMI and obesity. Results: (a) In both genders, association between childhood SES and adult obesity were accounted for entirely by adult SES, but its effect on adult BMI was observed only in women; (b) higher conscientiousness was associated with lower obesity prevalence and BMI in both genders, although more strongly in women, and in men, greater obesity prevalence was associated with higher agreeableness and neuroticism; and (c) personality explained unique outcome variation in both genders. Conclusions: Early social disadvantage may affect adult weight status more strongly in women owing to gender differences in the timing and nature of weight-management socialization. Personality may enhance or detract from risks incurred by childhood or adulthood SES in either gender, necessitating the consideration of dispositional differences in prevention and intervention programs.
