Self-regulation and personality: how interventions increase regulatory success, and how depletion moderates the effects of traits on behavior

Self-regulation is a highly adaptive, distinctively human trait that enables people to override and alter their responses, including changing themselves so as to live up to social and other standards. Recent evidence indicates that self-regulation often consumes a limited resource, akin to energy or strength, thereby creating a temporary state of ego depletion. This article summarizes recent evidence indicating that regular exercises in self-regulation can produce broad improvements in self-regulation (like strengthening a muscle), making people less vulnerable to ego depletion. Furthermore, it shows that ego depletion moderates the effects of many traits on behavior, particularly such that wide differences in socially disapproved motivations produce greater differences in behavior when ego depletion weakens the customary inner restraints.     

Spontaneous emotion regulation during evaluated speaking tasks: associations with negative affect, anxiety expression, memory, and physiological responding

In these studies, the correlates of spontaneously using expressive suppression and cognitive reappraisal during stressful speeches were examined. Spontaneous emotion regulation means that there were no instructions of how to regulate emotions during the speech. Instead, participants indicated after the speech to what extent they used self-motivated expressive suppression or reappraisal during the task. The results show that suppression is associated with less anxiety expression, greater physiological responding, and less memory for the speech while having no impact on negative affect. In contrast, reappraisal has no impact on physiology and memory while leading to less expression and affect. Taken together, spontaneous emotion regulation in active coping tasks has similar consequences as experimentally induced emotion regulation in passive tasks.     

Romantic love and sexual desire in close relationships

Drawing on recent claims in the study of relationships, attachment, and emotion, the authors hypothesized that romantic love serves a commitment-related function and sexual desire a reproduction-related function. Consistent with these claims, in Study 1, brief experiences of romantic love and sexual desire observed in a 3-min interaction between romantic partners were related to distinct feeling states, distinct nonverbal displays, and commitment- and reproductive-related relationship outcomes, respectively. In Study 2, the nonverbal display of romantic love was related to the release of oxytocin. Discussion focuses on the place of romantic love and sexual desire in the literature on emotion.     

Testing differences between nested covariance structure models: Power analysis and null hypotheses

For comparing nested covariance structure models, the standard procedure is the likelihood ratio test of the difference in fit, where the null hypothesis is that the models fit identically in the population. A procedure for determining statistical power of this test is presented where effect size is based on a specified difference in overall fit of the models. A modification of the standard null hypothesis of zero difference in fit is proposed allowing for testing an interval hypothesis that the difference in fit between models is small, rather than zero. These developments are combined yielding a procedure for estimating power of a test of a null hypothesis of small difference in fit versus an alternative hypothesis of larger difference.     

Cardiovascular disease prevalence and risk factors of persons with mental retardation

This paper reviews the recent literature on cardiovascular disease (CVD) prevalence, CVD-related mortality, physiological CVD risk factors, and behavioral CVD risk factors in adults with mental retardation (MR). The literature on the potential influences of modifiable behavioral CVD risk factors and the physiological CVD risk factors are also reviewed. Adults with mild to moderate MR residing in community settings appear to have an elevated disease prevalence, elevated CVD-related mortality, more adverse physiological CVD risk factors, and elevated behavioral risk compared to others with and without MR. Preliminary evidence supports the benefits of participating in the recommended physical activity levels and consuming the recommended diets to reduce the risk for CVD. The lack of large-scale longitudinal or experimental research indicates a gap in the research. The development of research-based, appropriate, primary prevention programs and intervention strategies aimed at lowering the risk for CVD is highly recommended. Programs should focus on educating individuals with MR along with direct care providers and family members on the importance of appropriate dietary concepts, physical activity habits, and regular health screenings by physicians. Programs should be individualized to regional and cultural issues.     

Progress in the Molecular-Genetic Study of Intelligence

ABSTRACT— The past decade has seen a major shift in the genetic study of human intelligence; where classic studies aimed to quantify the heritability of intelligence, current studies aim to dissect this heritability into its molecular-genetic components. Five whole-genome linkage scans have been published in the past year, converging on several chromosomal (or genomic) regions important to intelligence. A handful of candidate genes, some of which lie in these genomic regions, have shown significant association to intelligence and the associations have been replicated in independent samples. Finding genes brings us closer to an understanding of the neurophysiological basis of human cognition. Furthermore, when genes are no longer latent factors in our models but can actually be measured, it becomes feasible to identify those environmental factors that interact and correlate with genetic makeup. This will supplant the long nature–nurture debate with actual understanding.     

AN EMPIRICAL ANALYSIS OF MEASUREMENT EQUIVALENCE WITH THE INDCOL MEASURE OF INDIVIDUALISM AND COLLECTIVISM: IMPLICATIONS FOR VALID CROSS-CULTURAL INFERENCE

The INDCOL measure of individualism and collectivism ( Singelis et al., 1995 ) has been used increasingly to test complex cross-cultural hypotheses. However, sample differences in translation, culture, organization, and response context might threaten the validity of cross-cultural inferences. We systematically explored the robustness of the INDCOL, for various statistical uses, in the face of those 4 threats. An analysis of measurement equivalence using multigroup mean and covariance structure analysis compared samples of INDCOL data from the United States, Singapore, and Korea. The INDCOL was robust with regard to the interpretability of correlations, whereas differences in culture and translation pose an important potential threat to the interpretability of mean-level analyses. Recommendations regarding the interpretation of the INDCOL and issues in the analysis of measurement equivalence in cross-cultural research are discussed.     

Norme de motivation intrinsèque et utilité sociale : recherches dans le champ organisationnel

Numerous theoretical models have been proposed to explain motivation in organizational settings. Several authors such as Herzberg, Deci and Ryan distinguish between intrinsic and extrinsic motivation. A new approach to intrinsic motivation (François, 2003) is now developping in France. It consists of considering that “intrinsic motivation” is a social norm. We have tested the normativity of intrinsic motivation in two field studies using the judge's paradigm. The first study was conducted on 52 recruiters, the second was conducted on 25 experts evaluating a project concerning the creation of an organization. Results show that evaluators prefered intrinsically motivated than extrinsically motivated candidates in both studies. Finally evaluators used utilitarians traits to describe intrinsically motivated candidates. This result gives force to a normative interpretation of intrinsic motivation.
