Moral development, executive functioning, peak experiences and brain patterns in professional and amateur classical musicians: interpreted in light of a Unified Theory of Performance

This study compared professional and amateur classical musicians matched for age, gender, and education on reaction times during the Stroop color-word test, brainwaves during an auditory ERP task and during paired reaction-time tasks, responses on the Gibbs Sociomoral Reflection questionnaire, and self-reported frequencies of peak experiences. Professional musicians were characterized by: (1) lower color-word interference effects (Stroop task), (2) faster categorization of rare expected stimuli (P3b), and a trend for faster processing of rare unexpected stimuli (P3a), (3) higher scores on the Sociomoral Reflection questionnaire, and (4) more frequent peak experiences during rest, tasks, and sleep. Both groups had high values on the Brain Integration Scale. These findings are interpreted in light of a Unified Theory of Performance, which posits that effectiveness in any area is influenced by one’s level of mind-brain development—emotional, cognitive, moral, ego and cortical development—with higher mind-brain development supporting greater effectiveness in any domain.     

Exploratory regression analysis: A tool for selecting models and determining predictor importance

Linear regression analysis is one of the most important tools in a researcher’s toolbox for creating and testing predictive models. Although linear regression analysis indicates how strongly a set of predictor variables, taken together, will predict a relevant criterion (i.e., the multiple R), the analysis cannot indicate which predictors are the most important. Although there is no definitive or unambiguous method for establishing predictor variable importance, there are several accepted methods. This article reviews those methods for establishing predictor importance and provides a program (in Excel) for implementing them (available for direct download at . The program investigates all 2 ^p – 1 submodels and produces several indices of predictor importance. This exploratory approach to linear regression, similar to other exploratory data analysis techniques, has the potential to yield both theoretical and practical benefits.     

Toward a new approach to the study of personality in culture

We review recent developments in the study of culture and personality measurement. Three approaches are described: an etic approach that focuses on establishing measurement equivalence in imported measures of personality, an emic (indigenous) approach that studies personality in specific cultures, and a combined emic-etic approach to personality. We propose the latter approach as a way of combining the methodological rigor of the etic approach and the cultural sensitivity of the emic approach. The combined approach is illustrated by two examples: the first with origins in Chinese culture and the second in South Africa. The article ends with a discussion of the theoretical and practical implications of the combined emic-etic approach for the study of culture and personality and for psychology as a science.     

Can I retake it? Exploring subgroup differences and criterion-related validity in promotion retesting

Despite recent interest in the practice of allowing job applicants to retest, surprisingly little is known about how retesting affects 2 of the most critical factors on which staffing procedures are evaluated: subgroup differences and criterion-related validity. We examined these important issues in a sample of internal candidates who completed a job-knowledge test for a within-job promotion. This was a useful context for these questions because we had job-performance data on all candidates (N = 403), regardless of whether they passed or failed the promotion test (i.e., there was no direct range restriction). We found that retest effects varied by subgroup, such that females and younger candidates improved more upon retesting than did males and older candidates. There also was some evidence that Black candidates did not improve as much as did candidates from other racial groups. In addition, among candidates who retested, their retest scores were somewhat better predictors of subsequent job performance than were their initial test scores (rs = .38 vs. .27). The overall results suggest that retesting does not negatively affect criterion-related validity and may even enhance it. Furthermore, retesting may reduce the likelihood of adverse impact against some subgroups (e.g., female candidates) but increase the likelihood of adverse impact against other subgroups (e.g., older candidates).     

The metacognitions of climate change

How do individuals think about global climate change? Although a body of research on the cognitive elements of climate change has begun to accumulate (e.g., Bord, O'Connor, & Fisher, 2000, few studies have distinguished between categories of cognitions. One key distinction is between primary, direct thoughts such as perceptions and evaluations, and secondary, indirect thoughts which reflect upon and control primary cognitions (Petty, Brinol, Tormala, & Wegner, 2007); secondary thoughts are thus considered metacognitive. This distinction is important to climate change engagement given that primary and secondary thoughts may exert independent effects on behavior. Three metacognitive elements of climate change are delineated: metacognitive knowledge, or assessments of confidence in one's thoughts; metacognitive certainty, or assessments of the likelihood of an outcome; and metacognitive importance, or the relative emphasis placed on one's thoughts. The relations between these dimensions and climate change-relevant behaviors are explored. Possibilities for future research are also discussed.     

The elephant in the room: collaboration and competition among relief organizations during high-profile disasters

The non-governmental organizations (NGOs) that assume the bulk of emergency care during large-scale disasters in the developing world must expend considerable time and resources to ensure donations to sustain their field operations. This long-standing dilemma for the humanitarian community can create a competitive environment that: Compromises the delivery and quality of services, Allows the effectiveness of operations to be compromised by a lack of cooperation and collaboration, Disrupts the timely and accurate coordination and analysis of outcome measures that are crucial to successful response in the future, and Undermines the long-term capacity of indigenous aid organizations. This article addresses problems and potential solutions for improved coordination and long-term capacity-building of humanitarian aid.     

Voluntary task switching under load: Contribution of top-down and bottom-up factors in goal-directed behavior

The present study investigated the relative contribution of bottom-up and top-down control to task selection in the voluntary task-switching (VTS) procedure. In order to manipulate the efficiency of top-down control, a concurrent working memory load was imposed during VTS. In three experiments, bottom-up factors, such as stimulus repetitions, repetition of irrelevant information, and stimulus-task associations, were introduced in order to investigate their influence on task selection. We observed that the tendency to repeat tasks was stronger under load, suggesting that top-down control counteracts the automatic tendency to repeat tasks. The results also indicated that task selection can be guided by several elements in the environment, but that only the influence of stimulus repetitions depends on the efficiency of top-down control. The theoretical implications of these findings are discussed within the interplay between top-down and bottom-up control that underlies the voluntary selection of tasks.     

Integrating cross-cultural psychology research methods into ethnic minority psychology

Multicultural psychology has 2 related but often disconnected streams, namely cross-cultural psychology and racial and ethnic minority psychology (Hall & Maramba, 2001). We propose that advances in both fields will be facilitated if there is greater cross-fertilization, especially in methodological approaches given that proponents in both fields are interested in studying and understanding the role and impact of culture on human behavior. To facilitate this cross-fertilization, we present 3 methodological approaches that would be of value in racial and ethnic minority psychology. First, we present an overview of the importance of and the approaches to evaluating and establishing measurement equivalence. Second, we discuss recent advances in the understanding of conceptual equivalence in light of indigenous approaches, cultural manipulation, and multilevel analysis. Third, we present a combined etic-emic approach to cross-cultural personality research as illustrated by the Cross-Cultural Personality Assessment Inventory developed by Fanny Cheung and her colleagues.     

Automatic and controlled response inhibition: associative learning in the go/no-go and stop-signal paradigms

In 5 experiments, the authors examined the development of automatic response inhibition in the go/no-go paradigm and a modified version of the stop-signal paradigm. They hypothesized that automatic response inhibition may develop over practice when stimuli are consistently associated with stopping. All 5 experiments consisted of a training phase and a test phase in which the stimulus mapping was reversed for a subset of the stimuli. Consistent with the automatic-inhibition hypothesis, the authors found that responding in the test phase was slowed when the stimulus had been consistently associated with stopping in the training phase. In addition, they found that response inhibition benefited from consistent stimulus-stop associations. These findings suggest that response inhibition may rely on the retrieval of stimulus-stop associations after practice with consistent stimulus-stop mappings. Stimulus-stop mapping is typically consistent in the go/no-go paradigm, so automatic inhibition is likely to occur. However, stimulus-stop mapping is typically inconsistent in the stop-signal paradigm, so automatic inhibition is unlikely to occur. Thus, the results suggest that the two paradigms are not equivalent because they allow different kinds of response inhibition.     

The UCLA Body Project II: Breast and Body Dissatisfaction among African, Asian, European, and Hispanic American College Women

Breast and global body dissatisfaction were examined in Asian (n = 237), European (n = 196), Hispanic (n = 109), and African (n = 58) American college women. Asian American women reported the lowest body satisfaction on the Appearance Evaluation Scale (Cash, T. F. The multidimensional body-self relations questionnaire users’ manual: 3rd revision, 2000) and greatest breast dissatisfaction on one of two breast dissatisfaction measures. Ethnic differences in breast dissatisfaction, but not in body dissatisfaction, disappeared when body size (BMI) was statistically controlled. Results were consistent with research showing that (1) ethnic differences in body dissatisfaction are small, (2) studies of ethnic differences must include appropriate controls for total or specific body size, and (3) Asian college women report lower global body satisfaction than women of African, European, or Hispanic heritage.
