Positive life events and social support and the relationship between life stress and psychological disorder

Conclusion In conclusion, the present research demonstrated the deleterious effects of negative life events. Number of negative events was a significant predictor of psychological disorder even when initial disorder was statistically controlled. The cross-sectional regression findings provided some support for the stress-buffering effects of positive life events, but these effects were nonsignificant when initial disorder was statistically controlled. The cross-sectional and prospective regression findings suggest that received social support, as measured by the ISSB, does not have a direct or stress-buffering effect on psychological disorder. These analyses, however, demonstrated the direct and stress-buffering effects of perceived social support, as measured by the ISEL, and the data suggest that the ISEL is a promising measure of this construct.The authors thank Sheldon Cohen who provided helpful comments on an earlier version of this article.     

Religion and the morality of mentality

Christian doctrine considers mental states important in judging a person's moral status, whereas Jewish doctrine considers them less important. The authors provide evidence from 4 studies that American Jews and Protestants differ in the moral import they attribute to mental states (honoring one's parents, thinking about having a sexual affair, and thinking about harming an animal). Although Protestants and Jews rated the moral status of the actions equally. Protestants rated a target person with inappropriate mental states more negatively than did Jews. These differences in moral judgment were partially mediated by Protestants' beliefs that mental states are controllable and likely to lead to action and were strongly related to agreement with general statements claiming that thoughts are morally relevant. These religious differences were not related to differences in collectivistic (interdependent) and individualistic (independent) tendencies.     

Emotional and personality changes following cingulotomy

The effects of bilateral anterior cingulate cortex (ACC) lesions on emotional and personality functioning were studied. Patients undergoing cingulotomy for chronic intractable pain were assessed on the Minnesota Multiphasic Personality Inventory (MMPI), the Profile of Mood States (POMS), cognitive tests, and pain ratings, pre- and postsurgically. Patients with intractable pain, not treated with cingulotomy, served as controls. Cingulotomy patients experienced reductions in POMS-Tension, POMS-Anger, and MMPI Scale 7 (Psychasthenia) compared with baseline and the controls. POMS-Tension was significantly correlated with attention-intention performance. The results indicate that the ACC modulates emotional experience, related to self-perceived tension, and that there is relationship between the emotional and the attentional effects of cingulotomy.     

Daily affective reactivity as a prospective predictor of depressive symptoms

Daily affective reactivity refers to the within-subject relationship between daily stress and daily mood. Most stress researchers have conceptualized daily affective reactivity as a dependent variable to be predicted by individual difference variables such as personality and psychopathology. In contrast, in our recent research, we have conceptualized daily affective reactivity as an independent variable that can predict depressive symptoms. In this article, we summarize three studies that relied on a daily process methodology and multilevel modeling to assess affective reactivity in the context of daily stressful events. Two of the studies (Cohen, Butler, Gunthert, & Beck, 2005; Gunthert, Cohen, Butler, & Beck, 2005) sampled adult outpatients in cognitive therapy and evaluated the predictive role of daily affective reactivity in treatment outcome (depression reduction). A third study (O'Neill, Cohen, Tolpin, & Gunthert, 2004) evaluated the predictive role of college students' daily affective reactivity in the development of depressive symptoms. We consider the strengths and weaknesses of a daily process methodology for research on depression in both clinical and nonclinical samples.     

Does positive affect influence health?

This review highlights consistent patterns in the literature associating positive affect (PA) and physical health. However, it also raises serious conceptual and methodological reservations. Evidence suggests an association of trait PA and lower morbidity and of state and trait PA and decreased symptoms and pain. Trait PA is also associated with increased longevity among older community-dwelling individuals. The literature on PA and surviving serious illness is inconsistent. Experimentally inducing intense bouts of activated state PA triggers short-term rises in physiological arousal and associated (potentially harmful) effects on immune, cardiovascular, and pulmonary function. However, arousing effects of state PA are not generally found in naturalistic ambulatory studies in which bouts of PA are typically less intense and often associated with health protective responses. A theoretical framework to guide further study is proposed.     

Look little, look often: the influence of gaze frequency on drawing accuracy

The present article attempts to determine what those who draw accurately do differently than those who do not. Four experiments explore the relation between drawing accuracy and the rate at which artists glance between their drawing and the stimulus (termed gaze frequency). Experiment 1 revealed a positive relation between gaze frequency and drawing accuracy (r2 = .33). Experiments 2, 3, and 4 demonstrated that gaze frequency directly influences drawing accuracy. High gaze frequencies may facilitate drawing accuracy by (1) allowing the artist to hold less information in working memory, (2) reducing memory distortion, and (3) facilitating the reduction of context effects through inattentional blindness.     

A mechanism for error detection in speeded response time tasks

The concept of error detection plays a central role in theories of executive control. In this article, the authors present a mechanism that can rapidly detect errors in speeded response time tasks. This error monitor assigns values to the output of cognitive processes involved in stimulus categorization and response generation and detects errors by identifying states of the system associated with negative value. The mechanism is formalized in a computational model based on a recent theoretical framework for understanding error processing in humans (C. B. Holroyd & M. G. H. Coles, 2002). The model is used to simulate behavioral and event-related brain potential data in a speeded response time task, and the results of the simulation are compared with empirical data.     

The role of the locus coeruleus in mediating the attentional blink: a neurocomputational theory

The attentional blink refers to the transient impairment in perceiving the 2nd of 2 targets presented in close temporal proximity. In this article, the authors propose a neurobiological mechanism for this effect. The authors extend a recently developed computational model of the potentiating influence of the locus coeruleus-norepinephrine system on information processing and hypothesize that a refractoriness in the function of this system may account for the attentional blink. The model accurately simulates the time course of the attentional blink, including Lag 1 sparing. The theory also offers an account of the close relationship of the attentional blink to the electrophysiological P3 component. The authors report results from two behavioral experiments that support a critical prediction of their theory regarding the time course of Lag 1 sparing. Finally, the relationship between the authors' neurocomputational theory and existing cognitive theories of the attentional blink is discussed.     

The children in the community study of developmental course of personality disorder

The Children in the Community (CIC) Study is an ongoing investigation of the course of psychiatric disorders including personality disorders (PDs) in an epidemiological sample of about 800 youths. In addition to tracking developmental trajectories over 20 years from adolescence into adulthood, the CIC Study has used prospective data to investigate early risks for Axis II disorders and symptoms (including both environmental factors and early characteristics), implications of comorbidity with Axis I disorders, and associated negative prognostic risk of adolescent PDs into adulthood. The substantial independent impact of PD on subsequent Axis I disorders, suicide attempts, violent and criminal behavior, interpersonal conflict, and other problematic adult outcomes confirms the importance of attention to these problems when they manifest in early adolescence. The implications of study findings for potential changes in the DSM are discussed.
