该研究运用事件相关电位技术,采用肯定和否定的表达方式呈现自我参照任务,探讨不同表达方式对自我积极偏向效应的影响。实验一中,行为数据显示,自我积极偏向效应表现的并不完整;ERP数据显示,P200波幅的结果与行为数据结果相一致。实验二中,行为数据显示,自我积极偏向效应表现得完整;ERP数据显示,P200成分上并未产生任何实验效应。综合两个实验结果,证明了不同表达方式对自我积极偏向效应的表现存在影响。导致这种差异的根本原因可能在于两种表达方式造成的注意资源不同。 相似文献

This study extends multisource feedback research by assessing the effects of rater source and raters' cultural value orientations on rating bias (leniency and halo). Using a motivational perspective of performance appraisal, the authors posit that subordinate raters followed by peers will exhibit more rating bias than superiors. More important, given that multisource feedback systems were premised on low power distance and individualistic cultural assumptions, the authors expect raters' power distance and individualism-collectivism orientations to moderate the effects of rater source on rating bias. Hierarchical linear modeling on data collected from 1,447 superiors, peers, and subordinates who provided developmental feedback to 172 military officers show that (a) subordinates exhibit the most rating leniency, followed by peers and superiors; (b) subordinates demonstrate more halo than superiors and peers, whereas superiors and peers do not differ; (c) the effects of power distance on leniency and halo are strongest for subordinates than for peers and superiors; (d) the effects of collectivism on leniency were stronger for subordinates and peers than for superiors; effects on halo were stronger for subordinates than superiors, but these effects did not differ for subordinates and peers. The present findings highlight the role of raters' cultural values in multisource feedback ratings. 相似文献

When children ask, "What is it?" are they seeking information about what something is called or what kind of thing it is? To find out, we gave 2-, 3-, and 4-year-olds (32 at each age) the opportunity to inquire about unfamiliar artifacts. An ambiguous question was answered with a name or with functional information, depending on the group to which the children were assigned. Children were inclined to follow up with additional questions about the object when they had been told its name, but seemed satisfied with the answer when they had been told the object's function. Moreover, children in the name condition tended to substitute questions about function for ambiguous questions over the course of the session. These results indicate that children are motivated to discover what kinds of things novel artifacts are, and that young children, like adults, conceive of artifact kinds in terms of their functions. 相似文献

Mood affects social cognition and "theory of mind", such that people in a persistent negative mood (i.e., dysphoria) have enhanced abilities at making subtle judgements about others' mental states. Theorists have argued that this hypersensitivity to subtle social cues may have adaptive significance in terms of solving interpersonal problems and/or minimising social risk. We tested whether increasing the social salience of a theory of mind task would preferentially increase dyspshoric individuals' performance on the task. Forty-four dysphoric and 51 non-dysphoric undergraduate women participated in a theory of mind decoding task following one of three motivational manipulations: (i) social motivation (ii) monetary motivation, or (iii) no motivation. Social motivation was associated with the greatest accuracy of mental state decoding for the dysphoric group, whereas the non-dysphoric group showed the highest accuracy in the monetary motivation condition. These results suggest that dysphoric individuals may be especially, and preferentially, motivated to understand the mental states of others. 相似文献

I argue that the moral distinction in double effect cases rests on a difference not in intention as traditionally stated in the Doctrine of Double Effect (DDE), but in desire. The traditional DDE has difficulty ensuring that an agent intends the bad effect just in those cases where what he does is morally objectionable. I show firstly that the mental state of a rational agent who is certain that a side-effect will occur satisfies Bratman's criteria for intending that effect. I then clarify the nature of the moral distinction in double effect cases and how it can be used to evaluate the moral blameworthiness of agents rather than the moral status of acts. The agent's blameworthiness is reduced not by his lack of intention but by his desire not to bring about the side-effect, and the 'counterfactual test' can be used to determine whether he desires the effect in acting. In my version, the DDE has its rationale in virtue ethics; it is not liable to abuse as the traditional version is; and it makes more plausible distinctions when applied to standard examples. 相似文献

Preliminary neuropsychological outcomes of angioplasty and stenting of extracranial cerebral arteries 总被引:1,自引:0,他引:1
Preliminary evaluation of the neuropsychological status of three Chinese-speaking patients receiving angioplasty and stenting of extracranial cerebral arteries showed no significant decline in their performance on cognitive tasks measuring (1) memory function, verbal and nonverbal memory, (2) attention, and (3) cognitive processing speed. Although angioplasty and stenting of extracranial cerebral arteries did not appear associated with detrimental changes in the cognitive status of the two patients completing all cognitive tasks, their relation must be confirmed as a neuropsychologically safe measure for reducing the risk of stroke in Chinese with significant extracranial cerebral artery stenosis by a randomized controlled study with a much larger sample. 相似文献

The authors examined the relation among different facets of loneliness and depression in a sample of 6,356 Chinese children and adolescents from Grades 4-9. Loneliness and depression were closely related among the primary (Grades 4-6) and secondary (Grades 7-9) students, both boys and girls. Although the different facets of loneliness were predictive of the various facets of depression, peer-related loneliness and aloneness were more predictive of depression in both groups than was parent-related loneliness. The students in Grades 5 and 6 scored lower for loneliness but a little higher for depression than did the students in Grade 4. The students in Grades 8 and 9 scored higher than the students in Grade 7 for loneliness and depression. The primary boys scored higher than the primary girls for both loneliness and depression. Among the secondary students, there was no difference between the scores of the boys and those of the girls for loneliness, but the boys scored lower than the girls for depression. 相似文献

Intrusive parenting, primarily examined among middle to upper-middle class mothers, has been positively associated with the presence and severity of anxiety in children. This study employed cross-sectional linear regression and longitudinal latent growth curve analyses to evaluate the main and interactive effects of early childhood paternal autonomy restriction (AR) and neighborhood safety (NS) on the trajectory of child anxiety in a sample of 596 community children and fathers from the NICHD SECYD. Longitudinal analyses revealed that greater paternal AR at age 6 was actually associated with greater decreases in child anxiety in later childhood. Cross-sectional analyses revealed main effects for NS across childhood, and interactive effects of paternal AR and NS that were present only in early childhood, whereby children living in safer neighborhoods demonstrated increased anxiety when experiencing lower levels of paternal AR. Findings further clarify for whom and when paternal AR impacts child anxiety in community youth. 相似文献

The Internet is becoming the preferred place for finding information. Millions of people go online in search of health and medical information. Likewise, health care professionals must be able to retrieve and manage information in an efficient, effective manner. The development of health technology and informatics (HTI) has been rapid, yet little is known about the knowledge and attitudes of nursing students with regard to using HTI. Therefore, the objective of the present study was to explore nursing students' knowledge of and attitudes toward using HTI and to use an e-learning workshop to enhance the effective use of HTI. In Phase I, 115 first-year full-time nursing students were invited to complete a 13-item questionnaire regarding knowledge of and attitudes toward computer and Internet use, knowledge of HTI, and attitudes toward the future development of HTI. Participants perceived themselves to be knowledgeable in computer and Internet use, while knowledge of HTI was perceived to be low and attitudes toward the future development of HTI were generally positive. Phase II was an e-learning HTI workshop; topics included an introduction to HTI, examples of HTI in use, and the application and implementation of various HTI projects. There were 30 participants in the E-learning workshop, and their feedback was positive. Nurses and all health care professionals must be prepared to participate in the development of health technology and informatics. Teaching and learning activities should be geared toward mastery of HTI in the nursing education curriculum in order to enhance health care quality and safety. 相似文献

The purpose of this experiment was to examine the effects of choice and environmental control on the development of the perception of control. The results showed that the perception of control develops from an opportunity to make choices. More deliberate (slower) decisions resulted in an increase in the perception of control, and these perceptual effects generalized to a dice-throwing task over which no choice was possible. A model was examined which assumes that subjects monitor their own behavior with the result that more thoughtful decisions lead subjects to infer higher levels of control.A portion of these results was presented at the annual meeting of the South Eastern Psychological Association, 1983. This research was supported in part by the VA Medical Research Services, the U.S. Army Human Engineering Laboratory, and Grant AGO 2300 from the National Institute on Aging. Appreciation is expressed to Kathleen Flannery for her assistance with the preparation of this paper and for her helpful comments. 相似文献
