类别不确定下的特征推理是基于类别还是基于特征联结

共有3个实验探讨归类不确定情况下的特征推理是基于类别进行还是基于特征联结进行。实验1在中文条件下重复了Verde等人2005的实验,得出了与之相符的结果,这个结果用基于类别的理性模型的设想或者是用基于特征联结的设想都可以解释。实验2考察被试在靶类别的类别特征频次并且特征结合出现频次高低不同的条件下特征推理的情况,实验2的结果表明,高集中与低集中两种条件下特征推理没有显著差异,不符合特征推理是基于类别进行的设想,而与特征推理是基于特征联结进行的设想吻合。实验3进一步考察被试在特征结合出现的总频次并且靶类别中特征结合出现的总频次高低不同的条件下特征推理的情况,结果表明,在高结合条件下进行特征推理要优于在低结合条件,支持了在归类不确定情况下的特征推理是基于特征联结进行的设想。据此可以认为,人们的特征推理是基于特征之间联结的频次进行,而不是基于类别进行     

转化医学应用现状及其困境分析

转化医学的理念已经蓬勃发展起来,但对大多数处于临床一线的医生而言,却产生了较多困惑:基础医学与临床医学之间仍相互脱节,许多先进的基础医学研究难以为临床实践所用,基础医学的先进成果向临床的转化难以实现。因此,对于转化医学理念的提出,应有所反思,使转化医学的价值得以充分地发挥。     

生命健康视野下的叙事闭锁

从弗里曼的叙事闭锁理论出发,将“叙事闭锁”重新定义为“将自己禁锢在停滞的故事空间里,无法吸纳推动叙事进程向前发展的生命状态”,并将其进一步分为职业型、创伤型、疑虑型和老年型四种类型。叙事闭锁不仅在老年人群中高发,在其他年龄阶段人群中也不少见,以至于人生故事提前进入结束状态或者处于无法更新的停滞状态。对叙事闭锁者开展叙事介入可以帮助他们提升叙事素养,重启再次体验和阐释人生的按钮,赋予他们由内而外突破闭锁的能量。当人处于一种叙事稳定性和叙事开放性的平衡状态之中时,主体经历的就是一种健康和谐的生命进程。     

神灵主义医学何以可能?

神灵主义医学,是人类历史上第一个医学范式,拥有一套完整的形而上学信念、方法论体系和解释机制。神灵主义医学已经长期存在,并且在当今世界也广泛存在,这是世界之中的事实,无需争论。站在当代医学发展的前沿回头看,神灵主义医学之所以能够长期指导人类的医疗实践,有其内在原因。人类的大量自限性疾病,为神灵主义医学的成功提供了广泛的归纳支持。安慰剂效应的发现,进一步揭示了神灵主义医学成功的内在可能性。超自然解释,是神灵主义医学治疗失败后,医师给予患者的无助安慰,却为巫医守住了信誉的最后堡垒。     

历史的沉思：医学伦理学与生命伦理学学科特点及定位

对医学伦理学与生命伦理学学科的特点及定位进行再认识,是推动两个学科发展的理性前提。再认识需要历史视野,即将其置于该学科发展尤其是生成该学科的实践资源演变的历史长河中加以动态考察。研究表明,医学伦理学具有在传承中追求完善的职业实践性系列特点,定位为医学与伦理学交叉学科不存异议,将其称为人文医学学科具有创新价值,但需充分论证;生命伦理学虽同医学伦理学联系密切且有所重叠,但却具有追踪生命科学发展前沿的专业实践性系列特点,因而可将其定位为生命科学、伦理学、医学伦理学等相互交叉的新学科。     

科学发展观与生态医学模式

分析了生物医学模式没有转型为生物心理社会医学模式的原因。认为生态危机背景下的医学发展模式研究,应把提高人的生命质量和改善人的生存、生活环境等相关条件,纳入视野之中,这正表现出生态医学模式的价值基础与科学发展观在根本上的一致性。以生态医学模式引领未来医学发展是实践科学发展观的必然要求和具体行动。     

USING PARENTS TO MAINTAIN IMPROVED DENTAL FLOSSING SKILLS IN CHILDREN

An experimenter-administered intervention involving prompts, self-monitoring, permanent product collection, rewards for plaque reduction, and corrective feedback was used to improve the flossing skills of four 7- to 11-year-old children. Parents were subsequently trained in the reward and feedback procedures to facilitate maintenance. In a multiple baseline across subjects design, all four subjects snowed improvement in plaque between teeth during experimenter-administered intervention. Three subjects maintained low plaque levels during the 3- to 4-month parent-administered rewards and feedback follow-up condition. Improved plaque levels on nontargeted tooth surfaces also were observed. Pediatric dentistry applications are discussed.     

Building a primary care discipline: Notes from a psychologist in family medicine

Psychologists of a variety of emphases have actively participated in the growth of family medicine as an academic discipline. Rather than simply collaborate, they have shaped the very nature of the field. This paper describes a number of contributions from psychologists in family systems and educational arenas. In particular, physician-psychologist collaborative work is highlighted.     

The anthropological tradition in the philosophy of medicine

The tradition of anthropological medicine in philosophy of medicine is analyzed in relation to the earlier interest in epistemological issues in medicine around the turn of the century as well as to the current interest in medical ethics. It is argued that there is a continuity between epistemological, anthropological and ethical approaches in philosophy of medicine. Three basic ideas of anthropologically-oriented medicine are discussed: the rejection of Cartesian dualism, the notion of medicine as science of the human person, and the necessity of a comprehensive understanding of disease. Next, it is discussed why the anthropological movement has been superseded by the increasing interest in medical ethics. It is concluded that the present-day moral issues cannot be interpreted and resolved without clarification of the underlying anthropological images.     

OPERANT TREATMENT OF OROFACIAL DYSFUNCTION IN NEUROMUSCULAR DISORDERS

The popularity and reported success of biofeedback treatment for neuromuscular disorders has occurred despite a lack of research identifying the critical variables responsible for therapeutic gain. In this study, we assessed the degree to which severe neurological dysfunction could be improved by using one of the components present in all biofeedback treatment, contingency management. Three cases of orofacial dysfunction were treated by reinforcing specific improvements reliably detectable without the use of biofeedback equipment. The results showed that contingency management procedures alone were sufficient to improve overt motor responses but, unlike biofeedback treatment, did not produce decreases in the hypertonic muscle groups associated with the trained motor behavior. The findings suggest that sophisticated, expensive biofeedback equipment may not be necessary in treating some neuromuscular disorders and that important clinical gains may be achieved by redesigning the patient's daily environment to be contingently therapeutic, rather than only accommodating the disabilities of the physically handicapped.
