Objectives Fibromyalgia, a chronic pain syndrome, is often accompanied by psychological distress and increased basal sympathetic tone.
In a previous report it was shown that mindfulness-based stress-reduction (MBSR) reduced depressive symptoms in patients with
fibromyalgia with gains maintained at two months follow-up (Sephton et al., Arthr Rheum 57:77–85, 2007). This second study
explores the effects of MBSR on basal sympathetic (SNS) activation among women with fibromyalgia. Methods Participants (n = 24) responded to a television news appearance, newspaper, and radio advertisements. Effects on anxiety, depressive symptoms,
and SNS activation measures were tested before and after MBSR using a within-subjects design. Results The MBSR treatment significantly reduced basal electrodermal (skin conductance level; SCL) activity (t = 3.298, p = .005) and SCL activity during meditation (t = 4.389, p = .001), consistent with reduced SNS activation. Conclusions In this small sample, basal SNS activity was reduced following MBSR treatment. Future studies should assess how MBSR may
help reduce negative psychological symptoms and attenuate SNS activation in fibromyalgia. Further clarification of psychological
and physiological responses associated with fibromyalgia may lead to more beneficial treatment. 相似文献

This study examined the memorization of information after a night of normal sleep and total sleep deprivation (TSD) by means of event-related potentials (ERPs). We expected a disfacilitatory effect of TSD on memory processing. Eighteen subjects were tested twice in a counterbalanced fashion. During the study session, subjects were presented with unfamiliar face stimuli and asked to memorize them for a subsequent memory test. At the test session, the subjects were presented with the studied faces intermixed with “new” faces and asked to indicate the previously presented stimuli. The N100 was used as a covariate to control for the differences in level of vigilance between the two sessions. Sleep deprivation decreased subjects’ ability to discriminate new from previously studied stimuli and decreased the peak amplitude of the early component (N200) to the decrement of performance. In addition, following TSD the amplitude of the late frontal component (LFC), which is thought to reflect contextual processing, was decreased in covariance with the N100 vigilance component. The amplitude of the late posterior component (LPC/P600) was also reduced but was unrelated to the vigilance component of the ERP. Based on prior studies, this LPC reduction can be interpreted to indicate a decrease in information retrieved after TSD. In summary, a night of TSD decreased the amplitude of the ERPs associated with complex episodic memory task stimuli, affected the frontal cortex during episodic retrieval, and prevented the elaboration process. Furthermore, there was an inability to discriminate what is and what is not in memory, possibly due to less local processing of details. 相似文献

研究主要采用4(自尊类型)×2(词汇效价)混合设计,探讨了178名不同自尊水平或不同自尊类型大学生对自我相关信息的记忆偏好。结果发现:(1)高外显自尊者比低自尊者有更积极的记忆偏好,消极记忆偏好差异不显著;高内隐自尊者则比低自尊者有更弱的积极回忆偏好及更弱的消极回忆偏好。(2)就作为组内差异存在的记忆偏好而言,所有被试均有积极偏好;就作为组间差异存在的记忆偏好而言,脆弱的高自尊者有更强的积极偏好,但低自尊者也没有表现出明显的消极偏好。结果提示不同自尊者对自我相关信息有不同记忆偏好。 相似文献

小学四年级儿童简算策略获得的认知过程研究 总被引:1,自引:0,他引:1
研究策略获得的过程是了解认知机制的重要途径。本研究采用口语报告和教学实验的结合研究,采用策略意识和策略状况两个维度的评价指标考察,结果表明:策略运用从低到高体现出8级认知序列,策略获得者在策略的掌握过程中有四种认知状态:策略运用初期的倒退状态、策略从不熟练向熟练发展过渡的不稳定状态、策略运用的不彻底状态、有较强的策略意识但缺乏条件化知识的刻板状态。这四种状态反映出,学习者在策略获得过程中策略运用缺陷的常见状况。 相似文献

普通高校高水平运动员职业生涯规划的SWOT分析 总被引:1,自引:0,他引:1
“教体结合”模式已经成为高校高水平运动员培养和教育的重要形式,不仅有利于高水平运动员培养的可持续发展,而且有利于进一步提升校园文化内涵。但目前普遍存在的一个问题就是高水平运动员入校后,学训矛盾突出,职业生涯规划也难以开展,有待进一步探索。本文借鉴人力资源管理职业生涯规划理论和市场营销SWOT理论为基础,以SWOT分析为工具探讨如何科学实施高水平运动员职业生涯规划。 相似文献

不同复述条件下命名难度对图形记忆的影响 总被引:1,自引:0,他引:1
采用学习 -再认的方法对自由复述、部分特征的言语命名复述和视觉表象复述三种实验条件下图形的记忆效果进行了研究。结果表明 ,(1)图形记忆中存在明显的难度效应 ,难以命名图形的再认正确率高于易命名图形 ,反应时低于易命名图形。 (2 )被试在复述图形时 ,更倾向于选择那些难以命名的特征作为复述对象 ,以便把整个图形都记住。 (3)易命名图形的言语命名复述成绩好于视觉表象复述 ;而难以命名图形则不存在这种差异。两者自由选择时 ,将加快记忆提取的速度 相似文献

Periods of 24 to 48 hours of food deprivation reliably induced pup-killing in 30–50% of non-killer male mice. The behavior was prevented by previous experience with young and did not perseverate to non-deprived states. Castrated males and intact females also exhibited pup-killing following food deprivation, suggesting that the behavior is neither sexdependent nor related to the presence of testosterone. The findings are discussed in terms of their relationship to predatory behaviors and population dynamics. 相似文献

We tested Lykken’s (1995) theory that the personality trait of fearless dominance (FD) can result in positive or negative life outcomes depending on whether the socialization process was successful or not. We tested FD’s predictive and moderated relations with vocational success over a time interval of 4 years. We found that the relations between FD and change in income were moderated by level of education. When educational level was high (low), there was a positive (negative) relation between FD and change in income. Change in income mediated the relation between FA and vocational satisfaction. Finally, FD directly predicted vocational satisfaction after 4 years. Implications and limitations are discussed. 相似文献
