This study describes utilization of coping strategies and evaluates the interaction between coping strategies, depression, and quality of life (QOL) in patients with Parkinson's disease (PD) who are being considered for neurosurgical intervention. Eighty patients (mean age 61.7 years) with PD being evaluated for possible deep brain stimulation completed self-report instruments of coping strategies (Coping Responses Inventory), depression (Beck Depression Inventory), and disease-specific QOL (Parkinson's Disease Questionnaire-39). Analyses showed that patients with PD cope with the acute stressor of approaching neurosurgery through a variety of strategies, but particularly avoidant and behavioral strategies. When the correlated but apparently opposing effects of cognitive and behavioral strategies were teased apart, greater use of cognitive strategies was associated with more severe depressive symptomatology (and poorer QOL), while greater use of behavioral strategies appeared to be associated with less depression. Depressive symptomatology, in turn, was associated with poorer QOL. However, coping had minimal direct association with QOL. From this it was concluded that patients with advanced PD generate a variety of coping responses to an acute stressor such as surgery, and the use of behavioral strategies, in particular seeking of alternative enjoyable activities, may be associated with better mood if salutary effects are not overwhelmed by less helpful cognitive coping techniques. The minimization of depressive symptomatology, in turn, is associated with better QOL. 相似文献

Early emotional experiences affect developing brain systems that subsequently mediate adult learning and memory in rodents. Here we test for similar effects in squirrel monkeys (Saimiri sciureus) four years after disruptions in early maternal availability. These conditions were previously shown to generate differences in emotional behavior, hypothalamic-pituitary-adrenal stress physiology, and right ventral medial prefrontal volumes determined in adulthood by magnetic resonance imaging. This report identifies in the same monkeys variability in reward-related memory on tests with a spatial reversal. Adult monkeys that more often selected locations repeatedly rewarded before each reversal had larger right ventral medial prefrontal volumes, but not hippocampal nor dorsolateral prefrontal volumes on the left or right brain side. Differences in performance were also discerned after each spatial reversal. These findings indicate that maternal availability alters developing ventral medial prefrontal brain regions involved in reward-related memory. 相似文献

We investigated primary and secondary psychopathy and the ability to detect high-stakes, real-life emotional lies in an on-line experiment (N = 150). Using signal detection analysis, we found that lie detection ability was overall above chance level, there was a tendency towards responding liberally to the test stimuli, and women were more accurate than men. Further, sex moderated the relationship between psychopathy and lie detection ability; in men, primary psychopathy had a significant positive correlation with the ability to detect lies, whereas in women there was a significant negative correlation with deception detection. The results are discussed with reference to evolutionary theory and sex differences in processing socio-emotional information. 相似文献

Studies comparing young and older adults suggest a deficit in processing context information as a key mechanism underlying cognitive aging. However, the genetic architecture of context processing has not been examined. Consistent with previous results, we found evidence of functionally dissociable components of context processing accuracy in 1127 late middle-aged twins ages 51-60. One component emphasizes use of context cues to prepare responses (proactive cognitive control), and the other emphasizes adjustment of responses after probes are presented (reactive control). Approximately one-quarter of the variance in each component was accounted for by genes. Multivariate twin analysis indicated that genetic factors underlying two important components of context processing were independent of one another, thus implicating more than one underlying mechanism. Slower reaction time (RT) on noncontext processing trials was positively correlated with errors on the strongly proactive control component on which young adults outperform older adults, but RT was negatively correlated with errors on the strongly reactive control component on which older adults perform better. Although this RT measure was uncorrelated with chronological age in our age-homogeneous sample, slower RT was associated with performance patterns that were more like older adults. However, this did not generalize to other processing speed measures. Genetic correlations, which reflect shared genetic variance, paralleled the phenotypic correlations. There was also a positive genetic correlation between general cognitive ability and accuracy on the proactive control component, but there were still mostly distinct genetic influences underlying these measures. In contrast, the reactive control component was unrelated to general cognitive ability. 相似文献

Sandal, G. M. Bye, H. H. & Pallesen, S. (2012). Personality trait inferences of Turkish immigrant and neutral targets: An experimental study. Scandinavian Journal of Psychology 53, 528–533. The study investigated whether personality traits attributed to immigrant targets differ from personality inferences made for a neutral target, and whether trait attributions differ for assimilated and integrated immigrant targets. Participants (n = 340) were randomized to one of three conditions in which they read the same story about a person, but where the person was described as either: (a) an assimilated Turkish immigrant; (b) an integrated Turkish immigrant; or (c) neutral (no nationality or religious practice indicated). Subsequently, they rated the personality of the described person on the NEO‐Five Factor Inventory (observer rating version) and completed the Balanced Inventory of Desirable Responding (Impression Management scale) with reference to themselves. Both immigrant targets were rated as significantly higher on extraversion and lower on neuroticism than the neutral target. The integrated target was rated as more open than the neutral target, and as higher than the assimilated target on neuroticism when controlling for impression management. 相似文献

A general insight of 20th‐century philosophy of science is that the acceptance of a scientific theory is grounded, not merely on a theory’s relation to data, but on its status as having no, or being superior to its, competitors. I explore the ways in which scientific realists might be thought to utilise this insight, have in fact utilised it, and can legitimately utilise it. In more detail, I point out that, barring a natural but mistaken characterisation of scientific realism, traditional realism has not utilised that insight regarding scientific theories, i.e., has not explicitly factored that insight into, and invoked it as justification for, what realists believe. Nonetheless, a new form of realism has. In response to a key historical threat, two of the most thoroughly developed contemporary versions of realism—one put forward by Jarrett Leplin, another by Stathis Psillos—are anchored on the sensible tactic of requiring that the theories to which realists commit themselves have no competitors. I argue, however, that the particular kind of non‐competitor condition they invoke is illegitimate in the context of the realism debate. I contend further that invoking a non‐competitor condition that is legitimate, sensible, and even, as it turns out, required in the context of the debate threatens to eliminate the possibility of scientific realism altogether. 相似文献

We studied 9,220 children referred to a comprehensive mental health crisis stabilization program to examine the impact of
caregiver capacity on crisis worker decisions to refer children for intensive community-based treatment as opposed to inpatient
psychiatric hospitalization. Due to the different role of caregivers in the child welfare system, analyses were stratified
by state custody status. Among both groups, there was a significant inverse association between child mental health need and
referral to intensive community-based treatment. For children not in state custody with low mental health need, there was
no difference in the likelihood of referral to intensive community-based treatment across levels of caregiver capacity. However,
for children not in state custody with medium and high mental health needs, those whose caregivers were deficient or severely
deficient were significantly more likely to be referred for intensive community-based treatment than were those who had capable
caregivers. Multivariate analyses demonstrated similar results after controlling for potential confounding variables and confirmed
that caregiver capacity contributes significantly to the logistic model’s classification accuracy. Results suggest further
investigation of the impact of caregiver capacity on mental health crisis worker referral decisions is needed. 相似文献
