本文遵循信念指导我们的行动这一皮尔士观点,将基本信念描述为地图,而具有普遍内容的普遍信念则根本就不是命题,而是形成“说话者迎接未来的系统”的变形假言陈述。因果律是一种变形假言陈述,具有特殊的重要性和客观性。对于量化语句所表达的普遍信念,本文认为它们表达的是认知态度而非命题,从而明确支持了实用主义意义理论的核心论题。  相似文献

意义疗法是以存在积极心理学为理论基础,以构建个体生命意义为目的,实现生活正负两极性的动态平衡,从而解决其心理困扰获得心理治愈与成长的一种整合性心理咨询与治疗方法。起源于Frankl意义学说的意义疗法是通往人类美好生活的路径,它源于对苦难生活所隐含意义的本质认识。在理论上,意义疗法以意义定向看世界为中心,以意义管理理论和双系统模型为支架; 在方法上,为保障意义获得,应遵循8个基本问题和12条原则,充分发挥意义源的作用,实现意义获得的双路径统一; 在技术上,灵活采用趋向性(PURE)策略、回避性(ABCDE)策略、以及双视角双通道策略或其它策略的整合。意义疗法因包含了精神成分而超越了心理动力学和个体心理学等传统心理治疗方式。未来研究还需明确意义疗法整合了哪些流派的具体方法和技术,细化意义疗法主要的技术与策略的操作步骤,考察成熟幸福感量表在中国文化下的适用性,以及充分整合质性与量化研究方法检验意义疗法在中国的适用性  相似文献

生命意义是人类生命存在的永恒追求。东西方的理论均认为意义源于个体内在的自我结构,即自我概念。为了验证自我概念对生命意义的影响,对68名大学生进行实验研究。现场实验结果显示,控制生命意义基线水平和正负情绪后,自我概念仍显著预测生命意义;且自我概念提高组的生命意义得分显著高于降低组。行为实验结果显示,在高、低生命意义词汇记忆任务中,相比于低生命意义词,自我概念提高组对高生命意义词的再认率更高;相比于高生命意义词,自我概念降低组对低生命意义词的再认率更高。这些结果均表明,自我概念影响生命意义。结果暗示构建积极的自我概念形成强大的内心才是个体生命意义构建的根本途径。  相似文献

恰达也夫的《哲学书信》引起了一场争论。该信断言,俄国与其他国家不同,它没有任何深厚而又牢固的历史传统,它的历史也缺乏任何共同的思想和发展规律。俄国社会还是第一次见到有人对祖国的历史持这种观点,尽管这种观点流露出深深的痛苦和无法掩饰的悲观情绪。社会对上述观点不能不作出反应。在1830—1850年间,历史传统问题在俄国的思想争论中占有重要地位。  相似文献

Three pigeons chose between random-interval (RI) and tandem, continuous-reinforcement, fixed-interval (crf-FI) reinforcement schedules by pecking either of two keys. As long as a pigeon pecked on the RI key, both keys remained available. If a pigeon pecked on the crf-FI key, then the RI key became unavailable and the crf-FI timer began to time out. With this procedure, once the RI key was initially pecked, the prospective value of both alternatives remained constant regardless of time spent pecking on the RI key without reinforcement (RI waiting time). Despite this constancy, the rate at which pigeons switched from the RI to the crf-FI decreased sharply as RI waiting time increased. That is, prior choices influenced current choice-an exercise effect. It is argued that such influence (independent of reinforcement contingencies) may serve as a sunk-cost commitment device in self-control situations. In a second experiment, extinction was programmed if RI waiting time exceeded a certain value. Rate of switching to the crf-FI first decreased and then increased as the extinction point approached, showing sensitivity to both prior choices and reinforcement contingencies. In a third experiment, crf-FI availability was limited to a brief window during the RI waiting time. When constrained in this way, switching occurred at a high rate regardless of when, during the RI waiting time, the crf-FI became available.  相似文献

In a study of the discourse of 100 people with Alzheimer's disease treated for 12 months with donepezil, we observed that, as a group, they used a form of tag, described here as a self-referential tag (SRT), 14 times more frequently than did caregivers. Patients use SRTs to check propositions dependent on episodic memory as in I haven't seen the doctor recently, have I? and to monitor information flow as in I told you that already, didn't I? Based on criteria developed for distinguishing checking from monitoring tags, we document the type and frequency of patients' SRT use in the ACADIE corpus and analyze these in relation to standard measures of cognitive function (Mini Mental State Exam and Alzheimer's Disease Assessment Scale-cognitive sub-scale) at baseline and 12 months. Patients using monitoring SRTs (N=31), with or without checking SRTs, show significantly better cognitive test scores at 12 months, than are seen in patients who never use tags (N=29), or who only use checking tags (N=40). SRT use may be an independent measure of potential treatment responsiveness.  相似文献

Emerging evidence suggests that a traumatic brain injury (TBI) in childhood may disrupt the ability to abstract the central meaning or gist-based memory from connected language (discourse). The current study adopts a novel approach to elucidate the role of immediate and working memory processes in producing a cohesive and coherent gist-based text in the form of a summary in children with mild and severe TBI as compared to typically developing children, ages 8-14 years at test. Both TBI groups showed decreased performance on a summary production task as well as retrieval of specific content from a long narrative. Working memory on n-back tasks was also impaired in children with severe TBI, whereas immediate memory performance for recall of a simple word list in both TBI groups was comparable to controls. Interestingly, working memory, but not simple immediate memory for a word list, was significantly correlated with summarization ability and ability to recall discourse content.  相似文献

There are a number of problems and challenges in relating the science of epidemiology to mental retardation (MR). These relate to how MR is defined and classified and how these definitions may change over time. These as well as other differences in ascertainment sources and methods need to be considered when comparing MR prevalence over time and place. On the other hand, advances in technology also provide new and efficient methods of data collection both by data linkage and by use of web-based methods to study rare diseases. While prevalence studies have not been individually reviewed, we have examined the range of data including recent studies relating to how prevalence differs according to age, gender, social class and ethnicity. Some problems with available etiological classification systems have been identified. Recent etiological studies, most of which use different classification systems, have been reviewed and explanations have been postulated to account for differences in results. Individual risk factors for MR are considered whilst the option of considering a population as opposed to a high risk strategy to MR prevention is raised. This might well involve improving the social milieu surrounding the occurrence of individual risk factors. The impact of biotechnological advances such as antenatal and neonatal screening and assisted reproduction on MR are discussed. The issue of how inequalities in access to technology may impact on case identification and even have the potential to further widen inequalities is raised. The importance of extending the use of epidemiological tools to study the social, health and economic burden of MR is also emphasized. However, in order to apply to MR the "prevention-intervention-research" cycle, which surely underpins all epidemiology, it is vital to ensure that the methodological challenges we raise are adequately addressed.  相似文献

The work of a COPE study group on boundary violations is summarized, with particular focus on the impact on institutes and societies of sexual misconduct by training analysts. Difficulties in evaluating such situations are discussed, and the dynamics of institutional avoidance explicated. In addition, psychodynamic themes that are commonly observed in analysts who engage in sexual boundary violations with their patients are elaborated. Finally, suggestions are made for managing, through existing mechanisms, instances of boundary violations by training analysts.  相似文献

The medical records of 110 patients receiving conventional antipsychotics at two geographically distinct Veterans Administration hospitals (Syracuse, New York, and Omaha, Nebraska) were reviewed. The most common reasons for continuation of conventional antipsychotics were good response and patient or physician choice. Frequently, physicians did not discuss the reasons for continuing conventional antipsychotics or the availability of alternative therapies with their patients. Geographic differences in physicians' prescribing practices of conventional antipsychotics were apparent.  相似文献
