自发性脑出血作为临床常见疾病,其背景复杂,对其予以准确诊断较为困难。除最常见于高血压性脑出血外,其既可作为某些疾病的首发表现,也可作为其他疾病的并发症或某些药物治疗的副作用而出现。其准确诊断除需具备完整临床知识结构外,亦要求我们具有辩证思维。本文旨在从辩证思维和临床角度探讨自发性脑出血的准确诊断。 相似文献

In this paper we examined the impact of a specific emotion, guilt, on focusing in decision-making. Through the focusing mechanism, when making decisions, individuals tend to restrict their thoughts to what is explicitly represented in the decisional task, disregarding alternatives. In this paper, three experiments are performed to investigate whether an emotional state of guilt can critically guide individuals' focusing, and even prevailing over the focusing mechanism. Guilty emotional state was induced by asking participants to write about a guilty related life event. The emotional state was thus neither generated by nor related to the tasks used in the experiments. Results of the first two studies show that guilt affects focusing in decision-making in the case of only one explicitly specified option (a positive or a negative one). Guilty participants, when presented with a stated option that has predominantly positive characteristics, prefer other, unspecified options over the positive one. Guilty participants faced with a stated option that has predominantly negative features tend to prefer it to other, unspecified, options, instead. Finally, experiment 3 shows that guilty participants presented with two different options (a negative vs. a positive one) having different degrees of explicitness (i.e. they are not equally represented in the decision frame), focus on the negative option, even though the latter was not explicitly represented but only hinted at the end of the text. Overall, these results suggest that guilt emotion state can play a crucial role in either strengthening or reducing the focusing mechanism. Copyright © 2006 John Wiley & Sons, Ltd. 相似文献

We explored how political beliefs and attitudes predict support for anti‐Muslim policies and extremist behavior in the United States following the 2015 Paris terrorist attacks. A large sample completed measures of authoritarianism, social dominance orientation (SDO), generalized prejudice, identification with all humanity (IWAH), perceptions of Muslim threat, and support for anti‐Muslim policies and behaviors. These measures accounted for 73% of the variance in moderate anti‐Muslim policies and 55% of the variance in extreme anti‐Muslim policies. Authoritarianism and SDO directly and indirectly predicted support for anti‐Muslim policies, with their effects partially mediated by generalized prejudice, IWAH, and perceptions of Muslims as threatening. Threat both mediated and moderated the relationship between authoritarianism and anti‐Muslim policies. A negative interaction between authoritarianism and perceptions of Muslims as threatening predicted moderate anti‐Muslim policies, but a positive interaction predicted extreme anti‐Muslim policies. A tentative explanation is offered. Perceptions of Muslim threat was consistently a powerful predictor of anti‐Muslim policies and willingness to engage in extremist behaviors targeting Muslims. Programs to combat anti‐Muslim prejudice should consider the role of threat‐related stereotypes in expressions of anti‐Muslim prejudice. 相似文献

本研究通过两个实验考察不同效价度和唤醒度的情绪刺激是否存在动机倾向上的分离模式。实验1要求被试对表情图片的动机倾向(趋近/回避)进行主观评分,发现被试对低唤醒表情或积极表情有更加趋近的倾向。实验2以运动的线索启动动机倾向(趋近/回避),完成情绪词效价判断任务,从内隐的角度考察情绪刺激是否存在动机倾向上的分离模式,结果发现,被试对动机倾向一致的情绪刺激的反应时更快。趋近的消极情绪词比趋近的积极情绪词的N2波幅更大,远离的低唤醒情绪词比趋近的低唤醒情绪词的LPC波幅更大。结果说明积极或者低唤醒的情绪刺激引发趋近倾向,而消极或高唤醒的情绪刺激引发回避倾向。 相似文献

Three experiments examined the assertion that presession handling cues that accompany training with reinforcement might account for spontaneous recovery when they reoccur following extinction. In Experiment 1, after extensive training on a variable-interval schedule, key pecking in pigeons was extinguished following either normal or distinctively different handling and transportational cues. Those cues resulted in enhanced spontaneous recovery 24 hr later when normal cues were reinstated. In Experiment 2, however, subjects tested following the normal handling cues showed no more spontaneous recovery than did subjects that spent the entire extinction-test interval in the experimental chambers and thus were tested without handling cues altogether. In Experiment 3, a group whose test for recovery began 10 min after being placed in the chambers yielded as much spontaneous recovery as did a group tested normally. Furthermore, a group for which extinction began at mid-session and for which handling therefore could not be a discriminative cue for extinction showed no more spontaneous recovery than did the other two groups. Handling cues thus contributed to spontaneous recovery only after explicit discrimination training, as provided in Experiment 1. 相似文献

A time delay procedure was used to increase spontaneous verbalizations of 3 autistic children. Multiple baseline across behaviors designs were used with target responses, selected via a social validation procedure, of two spontaneous responses (“please” and “thank you”) and one verbally prompted response (“you're welcome”). The results indicate gains across target behaviors for all children, with occurrence across other stimuli and settings. These gains were validated socially with 10 adults. Furthermore, increases in appropriate language had no effect on levels of inappropriate speech. 相似文献

We investigated the effectiveness of teaching parents of 3 autistic boys to use a time delay procedure to increase their children's appropriate spontaneous speech in several naturally occurring daily settings (e.g., saying “good morning” in the morning). Generalization across settings and within settings across persons and locations was assessed. Variation in the children's spontaneous speech was also assessed. In addition procedural errors in the parents' use of time delay were calculated. Results indicated that all children increased their daily spontaneous speech and generalized their speech to other locations and persons. 相似文献

Self-control is widely believed to be a valuable characteristic that contributes to leading a healthy, happy, and successful life through the effective pursuit of long-term goals. Yet, despite a prolific literature spanning decades, essential questions about the conceptual nature of trait self-control remain unanswered. Substantially different perspectives on the theoretical nature of (trait) self-control coexist side by side. We briefly review prominent views informing what trait self-control as a psychological construct is. On this basis, we identify four conceptual challenges that we think the field should address moving forward: (a) integrating theoretical notions, (b) addressing variability in individual goals, (c) acknowledging variability in dominant responses, and (d) anchoring trait self-control in a nomological network. We highlight why addressing these challenges is crucial for gaining a deeper understanding of trait self-control. We also suggest how theoretical conceptualizations of trait self-control might do so and the implications this would bear for measurement and interventions. 相似文献

We conducted a comprehensive literature review of studies of word retrieval in connected speech in healthy aging and reviewed relevant aphasia research that could shed light on the aging literature. Four main hypotheses guided the review: (1) Significant retrieval difficulties would lead to reduced output in connected speech. (2) Significant retrieval difficulties would lead to a more limited lexical variety in connected speech. (3) Significant retrieval difficulties would lead to an increase in word substitution errors and in pronoun use as well as to greater dysfluency and hesitation in connected speech. (4) Retrieval difficulties on tests of single-word production would be associated with measures of word retrieval in connected speech. Studies on aging did not confirm these four hypotheses, unlike studies on aphasia that generally did. The review suggests that future research should investigate how context facilitates word production in old age. 相似文献

This paper offers a unifying conceptual explanation for failures in competitive decision making across three seemingly unrelated tasks: the Monty Hall game (Nalebuff, 1987), the Acquiring a Company problem (Samuelson & Bazerman, 1985), and multiparty ultimatums (Messick, Moore, & Bazerman, 1997). We argue that the failures observed in these three tasks have a common root. Specifically, due to a limited focus of attention, competitive decision makers fail properly to consider all of the information needed to solve the problem correctly. Using protocol analyses, we show that competitive decision makers tend to focus on their own goals, often to the exclusion of the decisions of the other parties, the rules of the game, and the interaction among the parties in light of these rules. In addition, we show that the failure to consider these effects explains common decision failures across all three games. Finally, we suggest that this systematic focusing error in competitive contexts can serve to explain and improve our understanding of many additional, seemingly disparate, competitive decision‐making failures.
