Positive and negative mood are independent psychological responses to stressful events. Negative mood negatively impacts well-being and co-occurring positive mood leads to improved adjustment. Women undergoing core needle breast biopsies (CNB) experience distress during CNB and awaiting results; however, influences of mood are not well known. This longitudinal study examines psychosocial and biopsy- and spirituality-related factors associated with mood in patients day of CNB and one week after receiving results. Ninety women undergoing CNB completed questionnaires on psychosocial factors (chronic stress, social support), biopsy experiences (pain, radiologist communication), and spirituality (peace, meaning, faith) day of CNB. Measures of positive and negative mood were completed day of CNB and one week after receiving results (benign n = 50; abnormal n = 25). Multiple linear regression analyses were conducted. Greater positive mood correlated with greater peace (β = .25, p = .02) day of CNB. Lower negative mood correlated with greater peace (β = ?.29, p = .004) and there was a trend for a relationship with less pain during CNB (β = .19, p = .07). For patients with benign results, day of CNB positive mood predicted positive mood post-results (β = .31, p = .03) and only chronic stress predicted negative mood (β = .33, p = .03). For women with abnormal results, greater meaning day of CNB predicted lower negative mood post-results (β = ?.45, p = .03). Meaning and peace may be important for women undergoing CNB and receiving abnormal results. 相似文献

Transgender individuals face heightened risks for discrimination, harassment, and violence that impact their psychosocial well-being and physical health. However, few studies have thoroughly examined the general physical and mental health of transgender adults or within-group health differences by race/ethnicity and income. To that end, after controlling for health insurance status, age, and engagement in exercise, this study asks: (a) Are transgender people of color more likely than White transgender individuals to experience poor health outcomes? and (b) Is lower annual household income among transgender adults associated with poorer health outcomes? The study analyzes secondary data from a survey of transgender adults (N = 417) in one state in the western United States using multiple linear regression and logistic regression models. Results showed that transgender people of color had significantly greater odds than their White counterparts of having arthritis/rheumatoid arthritis/gout/lupus/fibromyalgia, or asthma but lower odds of being told by a provider that they had depression. Having a lower income was significantly associated with worse general health as well as multiple indicators of poor physical and mental health, including depression, anxiety, and suicidal ideation. We discuss implications for health care delivery for transgender people and for future research. 相似文献

Although a group of people working together recalls more items than any one individual, they recall fewer unique items than the same number of people working apart whose responses are combined. This is known as collaborative inhibition, and it is a robust effect that occurs for both younger and older adults. However, almost all previous studies documenting collaborative inhibition have used stimuli that were neutral in emotional valence, low in arousal, and studied by all group members. In the current experiments, we tested the impact of picture-stimuli valence, picture-stimuli arousal, and information distribution in modulating the magnitude of collaborative inhibition. We included both younger and older adults because there are age differences in how people remember emotional pictures that could modulate any effects of emotion on collaborative inhibition. Results revealed that when information was shared (i.e., studied by all group members), there were robust collaborative inhibition effects for both neutral and emotional stimuli for both younger and older adults. However, when information was unshared (i.e., studied by only a single group member), these effects were attenuated. Together, these results provide mixed support for the retrieval strategy disruption account of collaborative inhibition. Supporting the retrieval strategy disruption account, unshared study information was less susceptible to collaborative inhibition than shared study information. Contradicting the retrieval strategy disruption account, emotional valence and arousal did not modulate the magnitude of collaborative inhibition despite the fact that participants clustered the emotional, but not neutral, information together in memory. 相似文献

In Memory: A Philosophical Study, Bernecker argues for an account of contiguity. This Contiguity View is meant to solve relearning and prompting, wayward causation problems plaguing the causal theory of memory. I argue that Bernecker’s Contiguity View fails in this task. Contiguity is too weak to prevent relearning and too strong to allow prompting. These failures illustrate a problem inherent in accounts of memory causation. Relearning and prompting are both causal relations, wayward only with respect to our interest in specifying remembering’s requirements. Solving them requires saying more about remembering, not causation. I conclude by sketching such an account. 相似文献

Objectives: Attribution of symptoms as medication side effects is informed by pre-existing beliefs about medicines and perceptions of personal sensitivity to their effects (pharmaceutical schemas). We tested whether (1) pharmaceutical schemas were associated with memory (recall/recognition) for side effect information (2) memory explained the attribution of a common unrelated symptom as a side effect.Design: In this analogue study participants saw the patient leaflet of a fictitious asthma drug listing eight side effects.Main outcome measures: We measured recall and recognition memory for side effects and used a vignette to test whether participants attributed an unlisted common symptom (headache) as a side effect.Results: Participants who perceived pharmaceuticals as more harmful in general recalled fewer side effects correctly (rCorrect Recall = ?.273), were less able to differentiate between listed and unlisted side effects (rRecognition Sensitivity = ?.256) and were more likely to attribute the unlisted headache symptom as a side effect (rside effect attribution = .381, ps < .01). The effect of harm beliefs on side effect attribution was partially mediated by correct recall of side effects.Conclusion: Pharmaceutical schemas are associated with memory for side effect information. Memory may explain part of the association between pharmaceutical schemas and the attribution of unrelated symptoms as side effects. 相似文献

A distributed connectionist network can account for both bookkeeping (M. Rothbart, 1981) and subtyping (M. B. Brewer, V. Dull, & L. Lui, 1981; S. E. Taylor, 1981) effects. The finding traditionally regarded as demonstrating subtyping is that exposure to moderate (compared with extreme) disconfirmers leads to subsequent ratings of the group that are less stereotypic. Despite learning that is incremental and analogous to bookkeeping, the simulations replicate this finding and suggest that the "subtyping" pattern of results will be drastically reduced if disconfirmers are encountered before the stereotype is well-established. This novel prediction holds with human participants and offers a tantalizing suggestion: Although moderate disconfirmers may produce more stereotype change. stereotype development might be discouraged by exposure to either extreme or moderate disconfirmers. 相似文献

In the present study, the contributions of spatial and object features to chimpanzees' comprehension of scale models were examined. Seven chimpanzees that previously demonstrated the ability to use a scale model as an information source for the location of a hidden item were tested under conditions manipulating the feature correspondence and spatial-relational correspondence between objects in the model and an outdoor enclosure. In Experiment 1, subjects solved the task under two conditions in which one object cue (color or shape) was unavailable, but positional cues remained. Additionally, performance was above chance under a third condition in which both types of object cues, but not position cues, were available. In Experiment 2, 2 subjects solved the task under a condition in which shape and color object cues were simultaneously unavailable. The results suggest that, much like young children, chimpanzees are sensitive to both object and spatial-relational correspondences between a model and its referent. 相似文献

Theories concerning the value of avoiding versus attending to trauma-related thoughts provide mixed support for specific coping strategies such as repression. The goal of this study is to examine the usefulness of the concept of repression in understanding chronic Posttraumatic Stress Disorder (PTSD). One hundred and fifty individuals who had been in a motor vehicle accident were included. Participants were classified into four groups (repressors, low anxious, high anxious, and defensively high anxious) based on methodology introduced by Weinberger et al. [J. Abnormal Psychol. 88 (1979) 369]. These four groups were compared on measures of PTSD symptomatology, anxiety, depression, and where appropriate, perceived pain and disability. Results revealed a fairly consistent pattern of group differences such that repressors reported fewer PTSD symptoms, fewer additional anxiety disorders, less depression, and less physical disability due to pain relative to the high anxious and defensively high anxious groups. Regression analyses examining the separate and interactive effects of anxiety and social desirability to predict PTSD symptomatology showed that the majority of the variance was explained by anxiety. In many respects, these data suggest that repression may not be a useful concept for understanding chronic PTSD. 相似文献
