Using a multimethod approach, the authors conducted 4 studies to test life span hypotheses about goal orientations across adulthood. Confirming expectations, in Studies 1 and 2 younger adults reported a primary growth orientation in their goals, whereas older adults reported a stronger orientation toward maintenance and loss prevention. Orientation toward prevention of loss correlated negatively with well-being in younger adults. In older adults, orientation toward maintenance was positively associated with well-being. Studies 3 and 4 extend findings of a self-reported shift in goal orientation to the level of behavioral choice involving cognitive and physical fitness goals. Studies 3 and 4 also examine the role of expected resource demands. The shift in goal orientation is discussed as an adaptive mechanism to manage changing opportunities and constraints across adulthood.  相似文献

An imbalance of the immune system and mixed personality profiles in suicide attempters have been reported. As suicidal behavior is common in patients with psychiatric disorders within the spectrum of depressive features, in this study we measured soluble interleukin-2 receptor concentrations in plasma (sIL-2R) and investigated temperament and character profile and their potential correlation in formerly depressed patients with a history of suicide attempt. We studied sIL-2R levels in plasma and personality characteristics (using Cloninger's Temperament and Character Inventory [TCI]) of formerly depressed patients who had attempted suicide a mean of 3 years previously (n = 25), and age and gender matched normal controls (n = 25). There was no significant difference in sIL-2R levels between formerly depressed suicide attempters and age and gender matched normal controls (0.23 ng/ml +/- 0.25 vs. 0.19 ng/ml +/- 0.16). When compared to normal controls, suicide attempt patients had a significantly higher score on the temperament dimension "harm avoidance" and a lower score on the character dimension "self-directedness." No significant correlation was found between sIL-2R values and TCI dimensions. We propose that the liability to suicidal behavior among suicide attempters susceptible to depressive symptomatology may be related to high harm avoidance and low self-directedness.  相似文献

Task preparation and stimulus-evoked competition   总被引:3,自引:0,他引:3  
The authors investigated how task competition evoked by a stimulus that affords both a currently relevant and a temporarily irrelevant task is affected by invalid preparation, i.e., preparation for the irrelevant task. Although invalid preparation was associated with a general performance cost, effects of stimulus-cued task competition were not enhanced on invalidly prepared trials. This result suggests that either preparation activates representations different from the ones by which stimulus cuing is mediated or that stimulus processing is postponed until invalid preparation has been corrected. In addition, invalid preparation resulted in impaired performance of the respective task when it became relevant on a subsequent trial. This result is consistent with the idea that competition due to invalid preparation is countered by task-specific inhibition.  相似文献

Hoffmann J  Lenhard A 《Journal of motor behavior》2004,36(4):384-5, 402-7; discussion 408-17
The authors argue that F. Mechsner's (2004) perceptual-cognitive approach is an important contribution to the current discussion of motor control. Mechsner presents convincing evidence against direct motor control. Nevertheless, the mechanisms by which perceptual-cognitive representations determine efferent commands must still be clarified.  相似文献

Two studies tested whether emotional disclosure increases feelings of closeness toward offenders. In Study 1, participants recalled either someone who had offended them or a neutral acquaintance. "Disclosure" participants then expressed their thoughts and feelings regarding their targets, and "suppression" participants described their targets nonemotionally. As predicted, disclosure increased closeness toward offenders but not toward acquaintances. Study 2 extended these results by including a good friend to test whether disclosure selectively increases closeness toward offenders, and not simply toward any person who evokes strong feelings. This prediction was confirmed. Furthermore, the disclosure effect remained reliable even after controlling for mood. Studies 1 and 2 also showed that closeness toward offenders, but not toward friends or acquaintances, was positively related to the proportion of emotion-related words disclosed. Collectively, these findings suggest that confronting the emotions associated with an offense may be an important first step toward forgiveness.  相似文献

This research tests whether people with high self-esteem are more informed by their emotions than are people with low self-esteem. In Study 1, participants listened to a series of disturbing baby cries, rated how much distress these cries conveyed, and reported their own emotional reactions to the cries. As predicted, the relation between participants' emotional reactions and their cry ratings was strongest at higher levels of self-esteem. In Study 2, self-esteem again determined how strongly participants' own emotional reactions influenced their baby cry ratings, even though esteem was measured weeks before the experiment and even after controlling for social desirability. Study 3 manipulated self-regard and showed that the correlation between participants' emotional reactions and their cry ratings was strong for high-regard participants, moderate for control participants, and weak for low-regard participants. These results suggest that self-esteem serves to validate the informational value of feelings.  相似文献

Human observers demonstrate impressive visual sensitivity to human movement. What defines this sensitivity? If motor experience influences the visual analysis of action, then observers should be most sensitive to their own movements. If view-dependent visual experience determines visual sensitivity to human movement, then observers should be most sensitive to the movements of their friends. To test these predictions, participants viewed sagittal displays of point-light depictions of themselves, their friends, and strangers performing various actions. In actor identification and discrimination tasks, sensitivity to one's own motion was highest. Visual sensitivity to friends', but not strangers', actions was above chance. Performance was action dependent. Control studies yielded chance performance with inverted and static displays, suggesting that form and low-motion cues did not define performance. These results suggest that both motor and visual experience define visual sensitivity to human action.  相似文献

A number of experimental data have shown that naming latency increases with length for pseudo-words but not for frequent real words. Different interpretations have been proposed by current models of reading to account for such a length effect. The aim of the present study was to assess the impact of lexicality on length effect in both the reading and lexical decision tasks. For this purpose, skilled readers were asked to either name or make a lexical decision on words and pseudo-words differing in length from one to three syllables. Skilled readers' results show that length effect is modulated by lexicality in the reading task but no length effect was found in the lexical decision task. The tasks were further proposed to a well-compensated dyslexic participant who exhibited a visual attentional disorder in the absence of any associated phonological problems. A length effect on RTs was found for both words and pseudo-words in lexical decision but naming latencies were affected by length for the pseudo-words only. The present results largely conform to the predictions of the ACV98 model of reading. They are not compatible with the PDP models of reading and can only be partially accounted for by dual route models.  相似文献

Eating disorders (ED), including anorexia and bulimia nervosa, are chronic illnesses with periods of symptom exacerbation and remission. Because symptoms are usually present from 6 to 24 months before a diagnosis is made, aetiological agents are believed to be active well before symptoms appear. It is proposed that neuropsychological deficits in various cognitive domains preexist and underlie the aetiology of ED. This paper provides a comprehensive review of the literature relevant to neuropsychological deficits in ED patients and explores the relationship between cognitive deficits, psychosocial development, and the development of ED. Although the role of neuropsychological deficits in the evolution of ED requires further research, the proposed association has significant implications for clinical practice.  相似文献

Mental health professionals' attitudes towards deaf people were examined in relation to their previous contact with deaf people and their knowledge of deafness. Data were gathered regarding different aspects of contact, including the number and type of relationships participants had had with deaf people. A cognitive-processing theory of attitude change following contact (Rothbart & John, 1985) was explored. Knowledge of deafness did not correlate with attitudes towards deaf people but a relationship was found between the amount of contact that professionals had with deaf people of equal or higher status and more positive attitudes.  相似文献
