The purpose of this study was to examine the relation of depression and anxiety to cancer patients' medical decision-making. Participants were 79 rural and urban cancer patients undergoing chemotherapy. The four decisional styles of the Decisional Processing Model were the independent variables. Dependent variables were anxiety and depression, measured by Spielberger's State-Trait Anxiety and the Center for Disease Control Depression Scale, respectively. Consistent with the Decisional Processing Model, analysis suggested that patients make medical decisions by information seeking, information processing, advice following, or ruminating. Decisional style did not vary according to type or stage of cancer, prognosis, time elapsed since initial diagnosis, or whether cancer was initial or recurrent. Decisional style did not systematically vary with depression and anxiety suggesting how a person makes decisions is a stable personality trait. Thus, decision-making may follow a cognitive schema. It is likely that patients' decisional styles help to manage anxiety and depression when confronted with life-threatening illness. Implications for informed consent and patients' involvement in decision-making are discussed. 相似文献

In this article we describe a child affected by right parieto-occipital lesion due to head injury. The patient showed left hemianopia, but not unilateral spatial neglect on traditional paper-and-pencil tests and on "ecological" tests. However, his parents reported frequent collisions with obstacles on the left side. A specific test was set up: The patient had to kick down skittles put on both sides of a route traced on the floor. He kicked down 89% of skittles on the right, but only 38% on the left side. These findings are discussed in light of recent theories on unilateral neglect. 相似文献

Direct comparison of episodic encoding and retrieval of words: an event-related fMRI study 总被引:5,自引:0,他引:5

Functional magnetic resonance imaging (fMRI) was used to compare directly episodic encoding and retrieval. During encoding, subjects studied visually presented words and reported via keypress whether each word represented a pleasant or unpleasant concept (intentional, deep encoding). During the retrieval phase, subjects indicated (via keypress) whether visually presented words had previously been studied. No reliable differences were found during the recognition phase for words that had been previously studied and those that had not been studied. Areas preferentially active during encoding (relative to retrieval) included left superior frontal cortex, medial frontal cortex, left superior temporal cortex, posterior cingulate, left parahippocampal gyrus, and left inferior frontal gyrus. Regions more active in retrieval than encoding included bilateral inferior parietal cortex, bilateral precuneus, right frontal polar cortex, right dorsolateral prefrontal cortex, and right inferior frontal/insular cortex. 相似文献

The use of a factorial survey to measure the clinical judgments of professionals is described. This design allows the researcher to partial out the effects of variables on clinical decision making while using probability sampling. Methods frequently used to study judgments are reviewed and a study of nurses' judgments about patients' confusional episodes are used to illustrate the application of the factorial survey. Acute confusion in patients is a common clinical problem for nurses working in medical-surgical units in acute care hospitals. Using the factorial survey to study a real-life problem such as confusion demonstrates how this design can be used to test judgments in complex clinical situations, to aid in concept development, and to identify consensus among professionals. 相似文献

In this study we investigated the correlation between individual linguistic ability based on performance levels and their engagement of typical and atypical language areas in the brain. Eighteen healthy subjects between 21 and 64 years participated in language ability tests, and subsequent functional MRI scans measuring brain activity in response to a sentence completion and a word fluency task. Performance in both reading and high-level language tests correlated positively with increased right-hemispheric activation in the inferior frontal gyrus (specifically Brodmann area 47), the dorsolateral prefrontal cortex (DLPFC), and the medial temporal gyrus (Brodmann area 21). In contrast, we found a negative correlation between performance and left-hemispheric DLPFC activation.Our findings indicate that the right lateral frontal and right temporal regions positively modulate aspects of language ability. 相似文献

Recent evidence suggests that decision makers in criminal procedures are susceptible to biases. We previously found support for the presence of a feature positive effect (FPE, i.e., people attach more meaning to present than to absent information) in legal-decision making. In this study, we tried to uncover the mechanisms behind the FPE. Taking a cue from the literature on situation models in language comprehension, we investigated whether a FPE manifests itself in the memorization and use of forensic evidence. Students read a case file about a fistfight as well as additional evidence. The forensic evidence was manipulated such that a FPE on guilt estimation and conviction rate could be assessed. While subjects read additional forensic evidence, their eye movements were recorded to explore the presence of FPE in online processing. Afterwards, subjects were asked to decide on the suspect's guilt. They had to recall all information they remembered from the case file and indicate which parts of information they considered relevant to this decision. The results provided evidence for the occurrence of FPE in memorization and use of information and can be explained by the theoretical construct of situation models. 相似文献

Children with early developmental delays are at heightened risk for behavior problems and comorbid psychopathology. This study
examined the trajectories of regulatory capabilities and their potentially mediating role in the development of behavior problems
for children with and without early developmental delays. A sample of 231 children comprised of 137 typically developing children
and 94 children with developmental delays were examined during mildly frustrating laboratory tasks across the preschool period
(ages 3–5). Results indicated that children with delays had greater use of maladaptive strategies (distraction, distress venting)
and lower use of adaptive strategies (constructive coping) than typically developing children. For both groups, strategies
had similar rates of growth across time; maladaptive strategies decreased and adaptive strategies increased. The intercept
of strategy use, but not the slope, was found to mediate the relation between developmental risk and externalizing behaviors.
Findings support that dysregulation, rather than the developmental risk, may be responsible for the high levels of comorbid
psychopathology. 相似文献

Shame, embarrassment, compassion, and contempt have been considered candidates for the status of basic emotions on the grounds that each has a recognisable facial expression. In two studies (N=88, N=60) on recognition of these four facial expressions, observers showed moderate agreement on the predicted emotion when assessed with forced choice (58%; 42%), but low agreement when assessed with free labelling (18%; 16%). Thus, even though some observers endorsed the predicted emotion when it was presented in a list, over 80% spontaneously interpreted these faces in a way other than the predicted emotion. 相似文献
