焦虑个体“冷”、“热”执行功能Stroop效应量比较 总被引:1,自引:0,他引:1
该文采用Stroop实验范式对筛选出的49名高焦虑个体和48名低焦虑个体的“冷”、“热”执行功能进行测量,以探讨不同焦虑程度个体“冷”、“热”执行功能间的差异。结果表明,在“冷”执行功能方面,高焦虑个体与低焦虑个体Stroop效应量之间没有显著差异;在“热”执行功能方面,两组被试情绪Stroop的效应量无差异;两类词;12的Stroop效应量差异显著;词汇类型×被试类型的交互作用非常显著;进一步的简单效应分析表明,两组被试的情绪Stroop效应量在消极词汇水平差异显著,两类词汇Stroop效应量在低焦虑组差异显著。说明高、低焦虑个体在“冷”执行功能上没有显著差异,高焦虑个体的“冷”执行功能正常,而“热”执行功能下降,表现为高焦虑个体对两极情绪的趋避关系失调,即对消极情绪具有偏向性,对积极情绪具有回避性。 相似文献

The standard Corsi blocks task is frequently used to measure the capacity of visuospatial working memory, but the implications of the use of both forward and backward recall are still unclear. In the present study, we showed that the backward Corsi task is particularly powerful in discriminating between low- and high-spatial-ability individuals and involves different processes from those involved in the forward task. From a sample of 425 participants we selected one group of 20 high-spatial-ability participants and one of 20 low-spatial-ability participants. The results demonstrated that a backward spatial span offers specific information not available from a forward spatial span, and that there was no facilitation due to a descending format. In particular, in the low-spatial-ability group, performance was generally poorer, but backward Corsi recall was lower than forward recall, and participants did not show any advantage following the descending presentation format—which in some contexts is considered to reduce proactive interference. We conclude that the backward Corsi task has specific value and that the assumption of fully parallel verbal and visuospatial working-memory systems can lead to a variety of misunderstandings. 相似文献

医护人员人文素质缺乏的管理责任及干预策略 总被引:3,自引:0,他引:3
医护人员人文素质缺乏与医学教育缺陷、人文管理意识不强、后续人文素质培养不利及执业环境恶化等综合因素密切相关。卫生行政主管部门和医院管理者首先应当确立人文管理理念,营造医院的人文氛围,承担起促进医学教育体制改革、加强岗位培训和着力培养社会需要的“人文科学型”医护人员的责任。 相似文献

Two experiments investigated preschoolers' interference control in variants of the day–night task. The day–night task involves instructing children across 16 trials to say the word ‘day’ when viewing a card depicting a nighttime sky and to say ‘night’ when shown a picture of the daytime sky. The purpose of the experiments was to investigate whether the depiction on each card distracts children because it is semantically associated with the instructed response or because the depicted item cues the alternative (incorrect) response within the response set. The results in the first study (N=23, M=52.65 months) and second study (N=54, M=50.81 months) indicate that a close semantic relation between the picture and the target response does not pose substantial interference for preschoolers. In contrast, the pictured item poses a significant challenge for preschoolers when it depicts the interfering alternative in the response set. Theoretical implications of these results for the development of interference control are discussed. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

Although attentional biases have been demonstrated in individuals with posttraumatic stress disorder (PTSD), the cognitive methodologies used have not allowed for disambiguation of two types of attentional biases. It remains unclear if PTSD involves difficulty disengaging attention from threatening stimuli (interference) or facilitated detection. To differentiate between attentional interference and facilitation, 57 male Vietnam-era veterans (30 High PTSD and 27 Low PTSD) completed a visual search task with a lexical decision component. High PTSD veterans who engaged in the interference task first showed increased interference to threat-relevant words relative to Low PTSD veterans. However, no evidence was found for facilitated detection of threatening stimuli in PTSD. 相似文献

Morrison and colleagues have proposed that auditory hallucinations are the result of cognitive intrusions being misattributed to an external source due to such thoughts being inconsistent with the person's beliefs about his or her own mental processes (metacognitive beliefs). The aim of this study was to investigate the applicability of this model to psychotic symptoms of thought interference. Fifty psychotic patients with and without thought interference were compared on (i) frequency of cognitive intrusions, (ii) metacognitive beliefs, (iii) source monitoring and (iv) appraisals of an unrelated anomalous event (a card trick). As predicted, individuals with thought interference had an increased frequency of cognitive intrusions and of maladaptive metacognitive appraisals, lower perceived cognitive control, and were more likely to endorse appraisals regarding 'permeability' of the mind, on the card trick task, in comparison to individuals without thought interference. No significant differences were found on any measure when the patient group was divided into hallucinators and non-hallucinators, once other variables were controlled for. These findings suggest that Morrison's model may be more parsimonious for symptoms of thought interference than for auditory hallucinations. 相似文献

The philosophical debate on paternalism is conducted as if the property of being paternalistic should be attributed to actions.
Actions are typically deemed to be paternalistic if they amount to some kind of interference with a person and if the rationale
for the action is the good of the person interfered with. This focus on actions obscures the normative issues involved. In
particular, it makes it hard to provide an analysis of the traditional liberal resistance to paternalism. Given the fact that
actions most often have mixed rationales, it is not clear how we should categorize and evaluate interfering actions for which
only part of the rationale is the good of the person. The preferable solution is to attribute the property of being paternalistic
not to actions, but to compounds of reasons and actions. The framework of action–reasons provides the tools for distinguishing where exactly paternalism lies in the complex web of reasons and actions. 相似文献

Purpose We adopted the conservation of resources model (COR, Hobfoll Am Psychol 44:513–524, 1989; Hobfoll in Stress, culture, and community: the psychology and philosophy of stress, Plenum, New York, 1998) to examine the associations among emotional labor, work family interference, and quality of work life.
Design/Methodology/Approach Cross-sectional, self-reported data were obtained from 442 Hong Kong Chinese service employees.
Findings Correlation and hierarchical regression analyses showed that surface acting was a salient correlate of work-to-family interference,
even when organizational display rules and employees’ demographic information were controlled. Furthermore, quality of work
life had partially mediated the relationship between surface acting and work-to-family interference. However, deep acting
and expression of naturally felt emotion did not relate to work-to-family interference. Finally, we found that family-to-work
interference was a salient correlate of the use of surface acting in workplace.
Implication This study provided useful information of how adopting different emotional labor strategies related to work family interference.
Based on our results, the use of deep acting should be promoted in workplace because it related positively to quality of work
life and it did not amplify the work-to-family interference.
Originality/value While past studies often explored the role of emotional labor as the precursor of work family interference, our study is among
the first attempt to examine family-to-work interference as the antecedent of emotional labor. Additionally, we had also confirmed
the role of quality of work life as an important mediator between emotional labor-work-to-family interference. 相似文献

免疫分析中抗体干扰相关问题的探讨 总被引:1,自引:0,他引:1

免疫分析是一项应用广泛的技术,抗体是免疫分析的关键问题。循环中内源性抗体对免疫分析的干扰与该技术本身一样古老,由于抗体干扰造成的可疑或错误的结果一直与其并存。但对于其机制、类型扣对策并未廓清。有鉴于此,有必要对抗体干扰免疫分析的诸多问题进行更深入的基础与临床研究,以提高临床诊断水平。 相似文献
