Relations between behavior analysis and ecological psychology have been strained for years, notwithstanding the occasional comment on their affinities. Harry Heft's (2001) Ecological Psychology in Context provides an occasion for reviewing anew those relations and affinities. It describes the genesis of ecological psychology in James's radical empiricism; addresses Holt's neorealism and Gestalt psychology; and synthesizes Gibson's ecological psychology and Barker's ecobehavioral science as a means for understanding everyday human behavior. Although behavior analysis is excluded from this account, Heft's book warrants a review nonetheless: It describes ecological psychology in ways that are congruent and complementary with behavior analysis (e.g., nonmediational theorizing; the provinces of natural history and natural science). After introducing modern ecological psychology, I comment on (a) Heft's admirable, albeit selective, historiography; (b) his ecological psychology—past and present—as it relates to Skinner's science and system (e.g., affordances, molar behavior); (c) his misunderstandings of Skinner's behaviorism (e.g., reductionistic, mechanistic, molecular); and (d) the theoretical status of Heft's cognitive terms and talk (i.e., in ontology, epistemology, syntax). I conclude by considering the alliance and integration of ecological psychology and behavior analysis, and their implications for unifying and transforming psychology as a life science, albeit more for the future than at present. 相似文献

慢性乙型肝炎病毒感染呈世界分布并且引起不良结局,是极为严重的健康问题。慢性乙型肝炎治疗最重要的目标是长期抑制病毒以改善预后,防止出现肝硬化、肝衰竭和肝癌。目前,抗病毒药物主要有干扰素和口服核苷(酸)类似物,核苷(酸)类似物的缺点主要在于长期治疗中出现耐药。路线图概念被用于监测耐药预测疗效。HBV DNA定量水平被作为路线图较好的监测指标。由于血清转换率及清除率过低,HBeAg、HBsAg定量检测不适合用于路线图监测,但对于使用聚乙二醇干扰素的慢性乙肝患者,可作为预测治疗应答的指标。 相似文献

为了解流行性乙型脑炎(乙脑)患儿血清神经元特异性烯醇化酶(NSE)、S-100蛋白(S-100)、髓鞘碱性蛋白(MBP)含量变化及其临床意义,用酶联免疫吸附法检测100例乙脑患儿血清NSE、S-100、MBP含量变化。结果显示,乙脑组患儿血清NSE、S-100、MBP含量与对照组比较显著增高(P均〈0.01),增高程度与病情严重程度相平行(P〈0.01)。因此,血清NSE、S-100、MBP含量测定对乙脑患儿脑损伤严重程度及临床预后判断有重要参考价值。 相似文献

捡了西瓜,就该丢掉芝麻吗——浅谈医源性Wernicke脑病 总被引:3,自引:0,他引:3
探讨医源性Wernicke脑病(WE)的病因、临床及磁共振图像特点,回顾性分析6例医源性WE病例。医源性WE病前均有禁食史,其临床表现多样。磁共振图像为中脑导水管周围T2WI及Flair高信号。大部分病例补充维生素B1后可好转。提示医源性禁食导致体内维生素B1耗竭是医源性WE的病因,及时补充维生素B1是预防及治疗本病的关键。 相似文献

The humor response has long been considered mysterious, and it is given relatively little attention in modern experimental psychology, in spite of the fact that numerous studies suggest that it has substantial benefits for mood and health. Existing theories of humor fail to account for some of the most basic humor phenomena. On most occasions when a humor response occurs, certain verbal or visual stimuli (the "setup" stimuli, which function as an establishing operation) must precede a critical stimulus (such as a "punch line" or the final panel or critical feature of a cartoon), which then occasions a sudden "revelation" or "understanding"; this revelation is often accompanied by the humor response. We suggest that the setup stimuli increase the strength of the revelatory response to a point just below the threshold of awareness and that the critical stimulus, properly designed and timed, edges the revelatory response to a point just above threshold. We also suggest that it is this threshold phenomenon that produces most instances of the humor response. We discuss these issues in the context of some notable humor of Carl Rogers and B. F. Skinner. 相似文献

我国是乙型病毒性肝炎高发区,母婴传播感染是一条极其重要且不易阻断的感染途径,由母婴传播导致的儿童乙肝病毒感染问题,不仅仅是现阶段我国严重的公共卫生问题,同时也是严重的社会伦理问题。HBV感染儿童在成长过程中所面临的社会歧视和自身权利保障是每一个患儿家庭迫切关心的,也是社会伦理学工作者的研究范畴。 相似文献

情绪记忆及其增强效应存在广泛的个体差异,这种个体差异可能有其神经与遗传基础。近来的行为遗传学与神经遗传学证实人类ADRA2B基因缺失突变以及BDNF Val66Met基因的多态性与情绪记忆增强及其神经机制的个体差异相联系。本文重点介绍与人类情绪记忆相关的这两种基因,梳理了行为与神经遗传学研究的最新进展,指出未来应关注更多候选基因,并重视多个脑区之间的交互作用;还应使用情绪面孔刺激探索BDNF Val66Met基因多态性对情绪记忆编码和提取的影响等。 相似文献

Peter B. Dews played a significant role in shaping the distinctive characteristics and defining the underlying principles of the discipline of behavioral pharmacology. His early and sophisticated use of schedules of reinforcement in the 1950s, incorporated from research in the experimental analysis of behavior and integrated into the discipline of pharmacology, provided tremendous insight, inspiration, and impetus to the newly emerging field of behavioral pharmacology. The experimental findings generated by Dews' research, blending the sophisticated use of behavior and pharmacological principles together with the elegant manner of their presentation and far-reaching implications, provided the force and momentum to establish and direct behavioral pharmacology for several decades. This article attempts to capture some of Dews' research that integrated and inspired the blending of sophisticated behavioral work with that of pharmacology. 相似文献
