In this article, the author describes a new theoretical perspective on positive emotions and situates this new perspective within the emerging field of positive psychology. The broaden-and-build theory posits that experiences of positive emotions broaden people's momentary thought-action repertoires, which in turn serves to build their enduring personal resources, ranging from physical and intellectual resources to social and psychological resources. Preliminary empirical evidence supporting the broaden-and-build theory is reviewed, and open empirical questions that remain to be tested are identified. The theory and findings suggest that the capacity to experience positive emotions may be a fundamental human strength central to the study of human flourishing.

Erik Eriksen is a remarkable individual. He has no college degrees yet is Professor of Human Development at Harvard University. He came to psychology via art, which explains why the reader will find him painting contexts and backgrounds rather than stating dull facts and concepts. He has been a training psychoanalyst for many years as well as a perceptive observer of cultural and social settings and their effect on growing up. This is not just a book on childhood. It is a panorama of our society. Anxiety in young children, apathy in American Indians, confusion in veterans of war, and arrogance in young Nazis are scrutinized under the psychoanalytic magnifying glass. The material is well written and devoid of technical jargon. The theme of the volume is that it is human to have a long childhood which will leave a lifelong residue of emotional immaturity in man.

We are in the midst of a technological revolution whereby, for the first time, researchers can link daily word use to a broad array of real-world behaviors. This article reviews several computerized text analysis methods and describes how Linguistic Inquiry and Word Count (LIWC) was created and validated. LIWC is a transparent text analysis program that counts words in psychologically meaningful categories. Empirical results using LIWC demonstrate its ability to detect meaning in a wide variety of experimental settings, including to show attentional focus, emotionality, social relationships, thinking styles, and individual differences.

Policy-makers are considering large-scale programs aimed at self-control to improve citizens’ health and wealth and reduce crime. Experimental and economic studies suggest such programs could reap benefits. Yet, is self-control important for the health, wealth, and public safety of the population? Following a cohort of 1,000 children from birth to the age of 32 y, we show that childhood self-control predicts physical health, substance dependence, personal finances, and criminal offending outcomes, following a gradient of self-control. Effects of children's self-control could be disentangled from their intelligence and social class as well as from mistakes they made as adolescents. In another cohort of 500 sibling-pairs, the sibling with lower self-control had poorer outcomes, despite shared family background. Interventions addressing self-control might reduce a panoply of societal costs, save taxpayers money, and promote prosperity.

Few models of self-control have generated as much scientific interest as has the limited strength model. One of the entailments of this model, the depletion effect, is the expectation that acts of self-control will be less effective when they follow prior acts of self-control. Results from a previous meta-analysis concluded that the depletion effect is robust and medium in magnitude (d = 0.62). However, when we applied methods for estimating and correcting for small-study effects (such as publication bias) to the data from this previous meta-analysis effort, we found very strong signals of publication bias, along with an indication that the depletion effect is actually no different from zero. We conclude that until greater certainty about the size of the depletion effect can be established, circumspection about the existence of this phenomenon is warranted, and that rather than elaborating on the model, research efforts should focus on establishing whether the basic effect exists. We argue that the evidence for the depletion effect is a useful case study for illustrating the dangers of small-study effects as well as some of the possible tools for mitigating their influence in psychological science.

Publication bias and the limited strength model of self-control: has the evidence for ego depletion been overestimated?

In 3 studies, the authors investigated whether within-persons increases in rumination about an interpersonal transgression were associated with within-persons reductions in forgiveness. Results supported this hypothesis. The association of transient increases in rumination with transient reductions in forgiveness appeared to be mediated by anger, but not fear, toward the transgressor. The association of rumination and forgiveness was not confounded by daily fluctuations in positive affect and negative affect, and it was not moderated by trait levels of positive affectivity, negative affectivity, or perceived hurtfulness of the transgression. Cross-lagged associations of rumination and forgiveness in Study 3 more consistently supported the proposition that increased rumination precedes reductions in forgiveness than the proposition that increased forgiveness precedes reductions in rumination.

Objective
There is increased interest in measuring peripheral oxytocin levels to better understand the role of this peptide in mammalian behavior, physiology, and disease. The purpose of this study was to compare methods for plasma oxytocin measurement using a commercially available enzyme immunoassay (EIA) and radioimmunoassay (RIA), to evaluate the need for sample extraction, and to assess the immunospecificity of the assays.

Background. The purpose of the study was to examine religious attendance as a predictor of survival in older adults. Methods. A probability sample of 3,968 community-dwelling adults aged 64-101 years residing in the Piedmont of North Carolina was surveyed in 1986 as part of the Established Populations for the Epidemiologic Studies of the Elderly (EPESE) program of the National Institutes of Health. Attendance at religious services and a wide variety of sociodemographic and health variables were assessed at baseline. Vital status of members was then determined prospectively over the next 6 years (1986-1992). Time (days) to death or censoring in days was analyzed using a Cox proportional hazards regression model. Results. During a median 6.3-year follow-up period, 1,777 subjects (29.7%) died. Of the subjects who attended religious services once a week or more in 1986 (frequent attenders), 22.9% died compared to 37.4% of those attending services less than once a week (infrequent attenders). The relative hazard (RH) of dying for frequent attenders was 46% less than for infrequent attenders (RH: 0.54, 95% CI 0.48-.0.61), an effect that was strongest in women (RH 0.51, CI 0.43--0.59) but also present in men (RH 0.63,95% CI 0.52--0.75). When demographics, health conditions, social connections, and health practices were con­ trolled, this effect remained significant for the entire sample (RR 0.72,95% CI 0.64-.81), and for both women (RH 0.65,95% CI 0.55--o.76,p<.OOOI)and men (RH 0.83, 95% CIO.69-1.00,p=.05).
