Selective age-related differences in source memory relative to item memory, and individual differences in memory performance in relation to anxiety were explored with high- and low-anxious subjects screened from normal young and elderly adults. They were read false facts about the locations of well-known and unknown sights in a male or female voice. Intentional and incidental learning instructions were administered for source memory. Selective age-related deficits in source memory were observed under both encoding conditions. Higher level of anxiety was related to lower memory performance only in the old group; this relation was stronger in source recall. The findings suggest that the presence of such selectivity is unrelated to the tradeoff between item encoding and source encoding. Anxiety affects the variability, and mediates the selectivity of age effects on episodic memory. 相似文献

中小学生对父母管教信息的认知、情绪与行为反应倾向 总被引:4,自引:0,他引:4
运用情境模拟的方法,对中小学生对父母管教信息的认知、情绪与行为反应倾向进行了研究。被试是616名中小学生。结果表明:(1)小学中年级以上学生对家长管教信息的情绪有较准确的认知;(2)不同管教信息的教育效能有优劣之分:诱导教诲最能引起被试的正面反应,其次是困扰担忧,伤心失望能引起部分学生的顺从反应,愤怒批评易引起子女的消极情绪和对抗行为。(3)父亲发出的管教信息比母亲更具权威性,更易引起子女积极的情绪体验与行为倾向。(4)学生对家长管教信息的反应具有明显的年龄和性别差异,小学生比中学生更易接受、顺从家长管教,女生比男生易产生更多的积极情绪与服从行为。(5)被试的认知评价与其情绪反应、行为倾向有较高的一致性。学生对父母管教信息的情绪体验和行为反应很大程度上取决于对管教信息的认知。如果学生的认知较为积极,更易引起积极的情绪体验和行为倾向。 相似文献

The safety and efficacy of medications for preventive treatment of migraine is the subject of current concern and investigation in health care. Two single-center, double-blind, placebo-controlled studies were conducted to evaluate the efficacy and safety of topiramate for migraine prophylaxis. Seventy patients with a diagnosis of migraine were randomly assigned to topiramate-treated and placebo groups. The studies consisted of a 4-week baseline phase, a 6-8 week titration, and 8-12 weeks of maintenance. Topiramate was titrated from an initial dose of 25 mg/day to a target dose of 100 mg BID. The primary efficacy measure, the mean 28-day migraine frequency, was lower in topiramate-treated patients than in the placebo group (3.2 versus 3.8, P=.001). Similarly, topiramate treatment resulted in a significantly greater mean reduction in migraine frequency than did placebo (1.55 versus 0.47, P=.001) and a significantly higher responder rate (35.3% versus 8.3%, P=.008). Paresthesia was the most common side effect reported with topiramate treatment. Other topiramate-associated adverse events included altered taste, memory impairment, diarrhea, and appetite suppression/weight loss. The rates of discontinuation were similar for the topiramate group (n=10) and the placebo group (n=8). These results suggest that topiramate is effective and well tolerated in the preventive treatment of migraine headaches. 相似文献

人体系统非优性的进化论诠释 总被引:3,自引:2,他引:1
吴廷瑞 《医学与哲学(人文社会医学版)》1999,20(1):20-23
从进化论的角度论述了人体系统非优性的成因,说明了生物竿化在人体系统中保留下大量的时空沉迹,其形式与特征表现为层次套叠,多元集合,转化退化。从而成为新与旧,高级与低级,复杂与简单,一句话就是优 与非优相互缠绕,相互作用,互补关联的协同统一性,而疾病的发生则是这种辩证统一的失调或破坏。 相似文献

兴奋性氨基酸(EAAs) 广泛分布于中枢神经系统,参与多种生理过程包括学习、记忆和伤害感受等。然而,EAAs 受体的过度兴奋却可引发一系列细胞事件,最终导致神经元的损伤与死亡。许多神经退行性疾病如早老性痴呆、癫痫和肌侧索硬化症等都与EAAs 的兴奋毒作用有关。目前的研究表明,由EAAs 受体过度兴奋所引发的细胞内钙超载是导致神经元死亡的最终途径 相似文献

思维风格测验在大学生中的初步应用 总被引:21,自引:1,他引:20
本文介绍了斯腾伯格的心理自我管理理论并使用斯腾伯格所编制的思维风格问卷对大学生的思维风格进行了测量,比较了思维风格在性别、文理科、地域等方面的个体差异,得出了中国大学生在思维风格方面的一些特点;研究了思维风格与一般智力的关系,发现思维风格与智力相关很低,说明思维风格是一种独立于智力的特质;同时对思维风格量表的信、效度及量表的结构进行了探讨。 相似文献

Two experiments were conducted to examine bidirectional semantic associations between power and weight using a priming paradigm. Bidirectionality in the relationship between power and weight was demonstrated, utilising tasks that were identical except that the orders in which the stimuli were presented were reversed. In Experiment 1, an empty scale leaning either leftward or rightward was used as a priming stimulus, and a scale that appeared in equilibrium with a pair of power words was used as a target stimulus. In Experiment 2, a scale with a pair of words that appeared in equilibrium was used as a priming stimulus, and an empty scale leaning either leftward or rightward was used as a target stimulus. We identified interaction effects between power and weight in both experiments. Associations between power and weight provide evidence for both conceptual metaphor views and evolutionary theory. The bidirectionality of metaphorical effects is in line with the strong version of metaphoric structuring. Both language and experiential correlations play important roles in the development of the mapping between power and weight. 相似文献

Middle school students in Lushan county (N = 315) were assessed 6 months after the Yaan earthquake using a trauma severity questionnaire, a posttraumatic fear questionnaire, a social support questionnaire and a posttraumatic growth inventory to examine the effects of posttraumatic fear and social support in the relationship between trauma severity and posttraumatic growth (PTG). The results showed that posttraumatic fear mediated the relationship between trauma severity and PTG, and social support moderated the relationship between posttraumatic fear and PTG. These findings suggested that trauma severity could be positively associated with PTG in a direct way or in an indirect way through posttraumatic fear. Moreover, posttraumatic fear had a positive relation to PTG under the condition of high social support level, whereas the relation was non‐significant when the level of social support was low. These results were discussed in terms of their implications for adolescents after trauma. 相似文献
