Review of empirical studies of Rorschach performance by older adults (age 65+) indicates that previous research findings of declining cognitive flexibility and impoverishment of personality may be artifacts of design methodologies that have failed to adequately account for biosocial-psychological differences between age groups and within the older age group itself. When findings are assessed in terms of variables reflective of age cohort as well as residential status, diagnosis, health status, and test-taking attitude, important data become available. Suggestions concerning test interpretation are offered in lieu of the current lack of age matched base rates for Rorschach scoring variables.  相似文献

Self-perception processes have been postulated to occur only to the extent that initial attitudes are weak. The present research asked whether the outcome of such a process is a strengthening of the attitude in question. Two experiments investigated the accessibility of attitudes from memory following self-inference from behavior. Experiment 1 examined the consequence for attitude accessibility of reviewing and considering previously performed religious behaviors that were recent and primarily unmanded versus distant in time and "manded" in nature. Experiment 2 involved the performance of a new behavior that was either required or freely chosen. In each case, control subjects either did not review prior behaviors or did not perform a new behavior. In both experiments, attitude accessibility, as measured by the latency of response to attitudinal inquiries, was enhanced by the consideration or performance of unmanded behavior, but not by manded behavior. The relevance of this finding to issues regarding attitude-behavior consistency and attitudinal persistence is discussed.  相似文献

Considering the opposite: a corrective strategy for social judgment   总被引:1,自引:0,他引:1  
It is proposed that several biases in social judgment result from a failure--first noted by Francis Bacon--to consider possibilities at odds with beliefs and perceptions of the moment. Individuals who are induced to consider the opposite, therefore, should display less bias in social judgment. In two separate but conceptually parallel experiments, this reasoning was applied to two domains--biased assimilation of new evidence on social issues and biased hypothesis testing of personality impressions. Subjects were induced to consider the opposite in two ways: through explicit instructions to do so and through stimulus materials that made opposite possibilities more salient. In both experiments the induction of a consider-the-opposite strategy had greater corrective effect than more demand-laden alternative instructions to be as fair and unbiased as possible. The results are viewed as consistent with previous research on perseverance, hindsight, and logical problem solving, and are thought to suggest an effective method of retraining social judgment.  相似文献

Attributions, beliefs about control, and adjustment to breast cancer   总被引:9,自引:0,他引:9  
Attributions for cancer and beliefs about control over cancer were examined for their association with adjustment to breast cancer. Although 95% of the respondents made attributions for their cancer, no particular attribution (e.g., stress, diet) was associated with better adjustment. Analyses of attributions of responsibility for the cancer to the self, environment, another person, or chance yielded only a negative relation between adjustment and blaming another person. In contrast, both the belief that one could now control one's cancer and the belief that others (e.g. the physician) could now control the cancer were significantly associated with good adjustment. Of the different types of control, cognitive control was most strongly associated with adjustment, behavior control was less strongly associated with adjustment, and information control and retrospective control were unassociated with adjustment. The theoretical and practical implications of these results are discussed.  相似文献

The present investigation sought to further delineate the Type A coronary-prone behavior pattern and to elucidate the psychophysiological process through which this behavioral disposition is translated into heart disease. Type A and Type B male subjects engaged in tasks that required varying degrees of activity before an assessment of challenge-seeking tendencies. Type A participants sought greater degrees of challenge than did their Type B counterparts. In addition, the more active the person with Pattern A had been immediately before the challenge-seeking opportunity, the greater the degree of challenge sought. Precedent activity level did not significantly influence challenge seeking in the Type B population. The Type A subjects also had significantly faster heart rates during performance of a challenging task. Pattern A behavior may be translated into heart disease through the cumulative deleterious effects of chronic and excessive challenge-induced cardiovascular excitation.  相似文献

Attributional models of depression suggest that depression is associated with internal, stable, and global causal explanations of events. However, the models do not specify whether the depressive attributional process involves the selection of certain causes, the assignment of dimensional meanings to those causes, or both. A distinction between these two processes was suggested by the findings that the choice of causes does not reliably indicate the perceived dimensions and that there is poor convergence between existing methods that assess causes and those that assess dimensions. When causes and dimensions were each measured in a manner that avoided confounding by the other, each made a unique contribution to the prediction of depression scores. Cause ratings alone were significantly associated with depression scores, but the optimal prediction of depression included both causes and dimensions. The implications of the distinction between these two processes for experimental manipulations of attributions and for reattribution training programs are discussed.  相似文献

It has been proposed that the law of non-contradiction be revised to permit the simultaneous truth and falsity of the key sentences of the logical paradoxes, e.g., This sentence is false. In an attempt to show to what extent this bizarre suggestion of inconsistent models or truth-value gluts is a coherent suggestion it is proved that a first-order language for number theory can be semantically closed by having its own global truth predicate under some non-standard interpretation and thus that it actually can contain the Liar sentence. It is proved that in this interpretation the Liar sentence is both true and false, although not every sentence is.  相似文献

Complaints of anxiety, often meetingDiagnostic and Statistical Manual of Mental Disorders, 3rd ed. (DSM-III), criteria for anxiety disorder, are among the most common problems presenting to health practitioners. In spite of the frequency of anxiety and anxiety disorders, little is known about the basic psychopathology of these conditions that would lead to the development of more efficient and effective treatments and possible preventive efforts. Recently, there has been an increase in research on the psychopathology of anxiety disorders from biological, psychological, and social perspectives. The National Institute of Mental Health's Clinical Research Branch sponsored a 2-day workshop of investigators representing diverse research approaches to discuss emerging issues and research practices within the anxiety disorders. Discussions centered on a review of the general areas of classification, phenomenology, and etiology. A selective summary of this workshop is presented along with recommendations for specific research directions.  相似文献
