An exploratory study of social support, distress, and life disruption among low-income Hispanic women under treatment for early stage breast cancer.

Relationships between distress and perceived availability of social support were examined in 51 Hispanic women being treated for early stage breast cancer. Distress and different types (emotional, instrumental) and sources (spouse, women family members, other family members, friends) of support were measured at presurgery, postsurgery, and at 3-, 6-, and 12-month follow-ups. Emotional support from friends and instrumental support from spouse at presurgery predicted lower distress postsurgery. No other prospective benefits of perceived support emerged. Distress at several time points predicted erosion of subsequent support, particularly instrumental support from women in the family. In contrast to the adverse effects of distress (and independent of them), illness-related disruption of recreational and social activities at 6 months elicited greater support at 12 months.     

Generalization, Adverse Events, and Development of Depressive Symptoms

Many diathesis-stress models have been proposed in which cognitive processes of various types are presumed to represent vulnerabilities to development of depressive symptoms. This study tested three potential vulnerabilities as prospective predictors of such symptoms: the holding of especially high standards, the tendency to be self-critical after failure, and the tendency to generalize from a single failure to the broader sense of self-worth. At the start of a semester, college students completed a measure of these cognitive tendencies and a measure of depressive symptoms. Six weeks later they completed the same measure of depressive symptoms and a brief measure of intervening life events. Hierarchical regression analysis yielded evidence that Generalization interacted with adverse events to predict subsequent depressive symptoms. Self-Criticism also tended to predict later symptoms, but only if the symptoms were present initially. High Standards had no adverse effect.     

Optimism, coping, and health: assessment and implications of generalized outcome expectancies

This article describes a scale measuring dispositional optimism, defined in terms of generalized outcome expectancies. Two preliminary studies assessed the scale's psychometric properties and its relationships with several other instruments. The scale was then used in a longitudinal study of symptom reporting among a group of undergraduates. Specifically, respondents were asked to complete three questionnaires 4 weeks before the end of a semester. Included in the questionnaire battery was the measure of optimism, a measure of private self-consciousness, and a 39-item physical symptom checklist. Subjects completed the same set of questionnaires again on the last day of class. Consistent with predictions, subjects who initially reported being highly optimistic were subsequently less likely to report being bothered by symptoms (even after correcting for initial symptom-report levels) than were subjects who initially reported being less optimistic. This effect tended to be stronger among persons high in private self-consciousness than among those lower in private self-consciousness. Discussion centers on other health related applications of the optimism scale, and the relationships between our theoretical orientation and several related theories.     

Effects of amount of attention allocated to the location of visual stimulus pairs on perception of simultaneity

This study examined whether a change in the amount of attention equally allocated to two locations affects judgments of the simultaneity or successiveness of stimuli presented at those locations. Observers were cued to expect two brief flashes either to the left and right of fixation or above and below fixation. Stimulus onset asynchrony was randomly varied. On a small proportion of trials, the stimuli appeared at the unexpected locations. Observers were more likely to report the stimuli as simultaneous when they appeared in the unexpected locations. A model proposed to account for the data assumes that a brief stimulus event is represented by a probability distribution reflecting the uncertainty in determining the time of the event’s occurrence, and two events are judged to be simultaneous if they are perceived to fall within some critical temporal interval, c, which is a function of the amount of attention allocated to the task.     

Physical aggression as a function of objective self-awareness and attitudes toward punishment

Based on a theory of self-awareness, it was hypothesized that subjects would use their attitudes to determine their behaviors when (a) that attitude was salient and (b) their attention was directed toward themselves. Subjects, who on questionnaires had indicated that they opposed or condoned the use of punishment, were given the opportunity to shock a male confederate in two (bogus) learning experiments. Each subject was instructed to use his own attitude in choosing shocks to punish incorrect responses. Self-awareness was increased among half the subjects by the presence of a mirror. In each experiment a Punitiveness by self-awareness interaction resulted: High Punitive-Mirror subjects shocked higher than Low Punitive-Mirror subjects, but their respective No Mirror controls did not differ from each other.     

Facilitation of physical aggression through objective self-awareness

Based on a theory of self-awareness it was hypothesized that induced attention to the self would facilitate aggression if the salient standard of behavior was one in which high aggression was positively valued. Female subjects were given an opportunity to shock a male confederate of the experimenter in a presumed learning experiment. Self-awareness was induced in half the subjects by the presence of a mirror. The Mirror group delivered significantly higher shocks to the confederate than did the No-Mirror control group.
