Four heads are better than one: combining face composites yields improvements in face likeness

Four participants constructed face composites, of familiar and unfamiliar targets, using Pro-Fit, with reference images present or from memory. The "mean" of all 4 composites, created by morphing (4-morph) was rated as a better likeness than individual composites on average and was as good as the best individual likeness. When participants attempted to identify targets from line-ups, 4-morphs again performed as well as the best individual composite. In a second experiment, participants familiar with target women attempted to identify composites, and the trend showed better recognition from multiple composites, whether combined or shown together. In a line-up task with unfamiliar participants, 4-morphs produced most correct choices and fewest false positives from target-absent or target-present arrays. These results have practical implications for the way evidence from different witnesses is used in police investigations.     

Out of sorts? Some remedies for theories of object concepts: a reply to Rhemtulla and Xu (2007)

Responds to comments made by Rhemtulla and Xu on the current authors' original paper Concepts of individual objects (e.g., a favorite chair or pet) include knowledge that allows people to identify these objects, sometimes after long stretches of time. In an earlier article, the authors set out experimental findings and mathematical modeling to support the view that judgments of identity depend on people's beliefs about the causal connections that unite an object's earlier and later stages. This article examines M. Rhemtulla and F. Xu's (2007) critique of the causal theory. The authors argue that M. Rhemtulla and F. Xu's alternative sortal proposal is not a necessary part of identity judgments, is internally inconsistent, leads to conflicts with current theories of categories, and encounters problems explaining empirical dissociations. Previous evidence also suggests that causal factors dominate spatio-temporal continuity and perceptual similarity in direct tests. The authors conclude that the causal theory provides the only existing account consistent with current evidence. (PsycINFO Database Record (c) 2007 APA, all rights reserved).     

Unexpected reduction in migraine and psychogenic headaches following rTMS treatment for major depression: a report of two cases

Our objective is to report a coincident reduction in headache pain in patients treated with repetitive transcranial magnetic stimulation (rTMS) for major depressive disorder (MDD). Two patients with a Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition diagnosis of MDD, non-responsive to prior antidepressant treatment who were enrolled in a sham-controlled, double-blind study of rTMS for MDD. After the study, it was revealed that both were in the active-treatment arm. Both patients suffered from near daily headaches and kept logs of headache frequency and severity before, during, and after the study. Headache pain was significantly reduced under double-blind conditions with rTMS treatment, but returned to baseline following cessation of rTMS treatment. Ultimately, when receiving rTMS post-study as a maintenance intervention for MDD (approximately 2 rTMS sessions/week), the positive effects on headache amelioration were sustained. Headache pain is frequently comorbid with mood disorders and has been reported as the most common side effect with rTMS. In these subjects, rTMS was, in fact, associated with relief of depressive symptoms and preexisting headache pain. This indicates that rTMS may be beneficial for both disorders in some patients.     

Childhood behavioral inhibition and the experience of social anxiety in American Indian adolescents

American Indian youth may be at increased risk for anxiety-related problems. Social anxiety is the most common form of anxiety experienced by adolescents, yet little research specific to American Indians has been conducted. Childhood temperament, especially behavioral inhibition (BI), has been identified as an important risk factor for social anxiety in other racial and ethnic groups. This study examined BI in relation to social anxiety in a cross-sectional community-based sample of 86 rural southeastern American Indian adolescents. Patterns of childhood BI suggested cultural variations in the way temperament relates to adolescent social anxiety. Specifically, nonsocially based fears in childhood were associated with social anxiety symptoms in adolescence, which is in contrast to previous findings in non American Indian samples that have suggested continuity between social inhibition in childhood and social anxiety in adolescence. It is recommended that major psychological risk factors, including temperament, be evaluated within the specific social and cultural context of the adolescent population of interest.     

Choosing the best method for local validity estimation: relative accuracy of meta-analysis versus a local study versus Bayes-analysis

This study assessed the relative accuracy of 3 techniques--local validity studies, meta-analysis, and Bayesian analysis--for estimating test validity, incremental validity, and adverse impact in the local selection context. Bayes-analysis involves combining a local study with nonlocal (meta-analytic) validity data. Using tests of cognitive ability and personality (conscientiousness) as predictors, an empirically driven selection scenario illustrates conditions in which each of the 3 estimation techniques performs best. General recommendations are offered for how to estimate local parameters, based on true population variability and the number of studies in the meta-analytic prior. Benefits of empirical Bayesian analysis for personnel selection are demonstrated, and equations are derived to help guide the choice of a local validity technique (i.e., meta-analysis vs. local study vs. Bayes-analysis).     

Peer group membership and a sense of belonging: their relationship to adolescent behavior problems

This study explored three aspects of peer group membership in adolescence: peer group affiliation, the importance of group membership, and a sense of peer group belonging. Each is considered in relationship to adolescents' behavior problems as measured by the Achenbach Youth Self-Report. Participants included an ethnically and socioeconomically diverse sample of 733 adolescents ranging in age from 11 to 18 years. Girls reported more internalizing problems and boys reported more externalizing problems. Girls also reported a higher sense of peer group belonging than boys. When controlling for adolescent age, gender, ethnicity, parent's educational level, and family structure, a sense of peer group belonging was negatively related to internalizing and externalizing behavior problems. Adolescents who viewed peer group membership as very important to them and had a positive sense of peer group belonging had significantly fewer behavior problems than those who viewed peer group membership as very important but did not have a positive sense of peer group belonging.     

Balancing Justice and Mercy

The concept of forgiveness is analyzed as a moral gesture toward the offender designed to help restore that individual's moral standing. Jewish sources on the conditions under which forgiveness is obligatory are explored and two contrasting positions are presented: one in which the obligation to forgive is conditional on the repentance of the offender and another in which people are required to forgive unconditionally. These two positions are shown to represent different ways of framing the offending behavior that rest, in turn, on different ways of balancing the need for justice and for mercy respectively. In the final analysis, Judaism's two contrasting attitudes toward forgiveness are rooted in different theological assumptions and different ways of construing the very goals of the moral life. The author points out the merits and shortcomings of both positions and concludes with the suggestion that the two complement each other in important ways.     

A Realist Sexual Ethics

A very liberal sexual ethics now holds sway in Western culture, such that mutual consent alone is widely seen as morally legitimizing almost any sexual activity between adults. It is further commonly assumed by both philosophers and nonphilosophers that arguing for some alternative to liberal sexual ethics requires appeal to ethical commands specific to some religious tradition or other. The purpose of this paper is to challenge that assumption by suggesting some purely naturalistic and independently‐plausible premises that can be used to argue for a much more conservative system of sexual ethics than is widely accepted today.
