In contrast to a recent finding (Macdonald, G. E., & De Toledo, L. Learning and Motivation, 1974, 5, 288–298.) the results of three experiments investigating various partial reinforcement (PRF) manipulations under conditions of thirst motivation demonstrated strong similarity to analogous manipulations involving food reward. Specifically, for animals receiving water reinforcement, PRF was shown to generate greater resistance to extinction than continuous reinforcement (Expt 1 & 3), the schedule of reinforcement was shown to interact with level of acquisition (Expt 1 and 2), and the magnitude of the partial reinforcement extinction effect was shown to be a function of reward magnitude (Expt 3). These results provide strong evidence that mechanisms which operate in partial reinforcement situations are highly similar, regardless of the type of appetitive reinforcement. 相似文献

McCauley, Stitt, Woods and Lipton's finding that groups were more conservative than individuals when betting at a race track has been criticized on statistical and methodological grounds. The present study which does not suffer the shortcomings for which McCauley et al. were legitimately criticized does, nonetheless, sustain their general results and conclusions. Groups were significantly more cautious than individuals when wagering $2.00 on a horse race. 相似文献

通过回顾国内外相关文献,从研究的意义、现状及研究的难点等方面综述慢性病患者及其配偶的二元应对纵向研究进展。结果显示夫妻的二元应对在不同疾病中随着时间推移呈不同的发展趋势;患者和配偶的二元应对方式及应对一致性对双方远期心理健康、关系质量等有重要的预测作用,且可能存在角色、性别、应对方式的差异。国内目前在该方面的研究较少,可借鉴国外研究方法,探究不同疾病背景下夫妻二元应对的发展及其对心理社会适应的预测作用,为制定有针对性的二元干预措施提供指导。

慢性非传染性疾病的急剧增加, 亚健康状态的出现, 不良生活方式的广泛存在, 对人们的健康产生了越来越显著的影响。研究认为, 科学的慢性病管理应当包括亚健康和不良生活方式在内的全人群的慢性病预防。从两种体检、三个状态、九种体质、四种干预方法出发, 提出以健康帮扶、健康促进、体质调理为特色的“二三九四”中西医结合慢性病管理模式。进一步联合企业和社区的初步实践证明, 该模式有利于降低亚健康的现患率, 可提高健康人群的比例, 为中西医结合防治慢性病提供了一定的参考。 相似文献

慢性非传染性疾病对居民健康的威胁与日俱增。预防和控制慢性病的蔓延是卫生工作者和公共卫生系统面临的挑战, 也关系到国家社会经济能否持续健康的发展。在社会资本理论这一全新视角下, 分析如何构建社区慢性病防治体系, 整合社会资源, 改善人际网络关系。社区慢性病防治体系的建立将为社会资本的重组和再生形成助推器, 并有助于实现二者的相互促进, 同时, 对提高医疗资源的使用效率, 减轻患者及其家属的经济负担, 建立互信互利的社区慢性病防治平台具有重要的现实指导意义。 相似文献

We tested the hypothesis that a narrative approach may enhance a bio‐psycho‐social model (BPS) in caring for chronically ill children. Forty‐eight narratives were collected from 12 children with six different medical conditions, their mothers, physicians, and nurses. By a textual analysis, narratives were classified on their predominant focus as disease (biological focus), illness (psychologic focus), or sickness (social focus). Sixty‐one percent of narrative’ text were classified as illness, 28% as disease and 11% as sickness. All narratives had a degree of illness focus. Narratives by patients and physicians on the one hand, and nurses’ and mothers’ on the other were disease focused. Narratives were also evaluated with respect to the type of medical condition: Illness was largely prevalent in all but Crohn’s disease and HIV infection, the latter having a predominance of sickness most probably related to stigma. Narrative exploration proved a valuable tool for understanding and addressing the needs of children with complex conditions. Narrative approaches allow identification of the major needs of different patients according to health conditions and story tellers. In the narratives, we found a greater illness and disease focus and surprisingly a low sickness focus, except with HIV stories. Narrative medicine provides a tool to strengthen the BPS model in health care. 相似文献
