麻疹是一种急性呼吸道传染病,常见于6月~5岁儿童。近年来婴儿和成人麻疹患者在总患者数中所占比率表现出上升的趋势,容易造成误诊、漏诊。作为临床工作者,我们认为临床医生应充分认识到麻疹发病人群及年龄的改变,在临床工作中减少误诊,并为患者提供及时有效的治疗,对高危人群的有计划干预对于减低成人麻疹发病率有着重要作用。本文针对婴儿和成人麻疹的诊断和治疗进行了综述,试图提供参考。  相似文献

近十年来,尺寸匹配误差作为年幼儿童生活中的一种常见的尺寸误用现象逐渐受到了一些研究者的关注。现有研究主要集中在尺寸匹配误差的特点、出现频率和产生原因等方面。抑制控制的失败、神经通路的协调失败、“计划-控制”模型和“感觉-行动”模型、功能性推理偏好以及身体意识发展的不成熟等观点能够对某些类型的尺寸匹配误差现象做出解释。未来的研究应从进一步深入探讨尺寸匹配误差与假装的区别、完善研究方法以及跨文化研究的开展几方面进行。  相似文献

A positive effect of breastfeeding on the mother–infant relationship is often assumed in the scientific literature, but this has not been systematically reviewed. This review aims to clarify the role of breastfeeding in the mother–infant relationship, which is conceptualized as the maternal bond toward the infant and infant attachment toward the mother. Our findings indicate that theoretical mechanisms through which breastfeeding may enhance the maternal bond or infant attachment (i.e., endocrine and sensory factors involved in breastfeeding) can be found in both humans and animal models. However, the few empirical studies investigating this association have not found convincing support for a relation between breastfeeding and the quality of the mother–infant relationship. We therefore conclude that assumptions on a positive role of breastfeeding on the mother–infant relationship are not supported by empirical evidence, and recommendation of breastfeeding should solely be based on its well-documented positive effects on infant and maternal health.  相似文献

From 1957 through the mid-1970s, John Bowlby, one of the founders of attachment theory, was in close personal and scientific contact with Harry Harlow. In constructing his new theory on the nature of the bond between children and their caregivers, Bowlby profited highly from Harlow’s experimental work with rhesus monkeys. Harlow in his turn was influenced and inspired by Bowlby’s new thinking. On the basis of the correspondence between Harlow and Bowlby, their mutual participation in scientific meetings, archival materials, and an analysis of their scholarly writings, both the personal relationship between John Bowlby and Harry Harlow and the cross-fertilization of their work are described.

Frank C.P. van der Horst   is a PhD student and Lecturer at the Centre for Child and Family Studies at Leiden University, The Netherlands. The work presented in this special issue is part of his doctoral thesis on the roots of Bowlby’s attachment theory. The defence of this thesis, titled John Bowlby and ethology: a study of cross-fertilization, is scheduled for early 2009. Helen A. LeRoy   recently retired from the Harlow Primate Lab at the University of Wisconsin-Madison after working there for nearly half a century. During that time, she worked closely with Harry Harlow from her arrival in 1958 until his retirement in 1974. She was Harlow’s executive assistant and was his help and stay in the editing of the Journal of Comparative and Physiological Psychology. René van der Veer   is Professor of History of Educational Thinking at Leiden University, The Netherlands. His research addresses the work of key educational thinkers such as Gal’perin, Janet, Piaget, Vygotsky, Werner, and Wallon. In a longer study the origin of the idea of the social mind was traced. He is on the Editorial Board of Integrative Psychological and Behavioral Sciences.  相似文献

ABSTRACT— Early theories of how infants develop spatial concepts focused on the perceptual and cognitive abilities that contribute to this ability. More recent research, however, has centered on whether experience with spatial language might also play a role. The present article reviews how infants learn to form spatial categories, outlining the perceptual and cognitive abilities that drive this learning, and examines the role played by spatial language. I argue that infants' spatial concepts initially are the result of nonlinguistic perceptual and cognitive abilities, but that, as infants build a spatial lexicon, spatial language becomes an important tool in the spatial categories infants learn to form.  相似文献

This paper presents data on the behaviours and food types associated with the transfer of individual food items in Temminck's red colobus (Procolobus badius temminckii). The relevance of (a) male–female differences and (b) the properties of the individual food items are addressed. Although the data are limited, it does suggest that food transfer, in this species, is infrequent, not particularly related to increasing nutritional knowledge or value, usually involve highly visible large items and is predominantly an aggressive male behaviour—from infancy through adulthood.

Social Anxiety Disorder (SAD) is a heterogeneous and distressing problem for many children and youth. This review focuses on the etiology and maintenance of SAD, and examines research findings in several key areas of investigation: genetic or hereditary factors (twin and family studies), temperament characteristics (behavioural inhibition), and parent–child interactions (attachment, parenting styles). It is concluded that genetic influences, behavioural inhibition, and parent–child interactions play significant and interactive roles in the development and maintenance of SAD. Other influences such as peer relationships, social skills deficits, and traumatic experiences are also acknowledged. Ultimately, an understanding of such pathways should facilitate effective early screening and intervention of children at risk for severe social anxiety.  相似文献

The author draws attention to something distinctive in the psychoanalytic 'air' from the early 1960s onwards: the strong emphasis upon the very early psychological, emotional and cognitive view of infants and young children. She focuses on the work of two analysts in particular, Esther Bick and Wilfred Bion, and the comparable, though differently expressed, centrality of the observational method in their work. Each explored not only the pathological picture but also the nature and integrative function of psychic containment in earliest mental life. Each also shared a preoccupation with what constituted a psychoanalytic attitude and with the process of becoming a psychoanalyst and, in Bick's case, a child analyst or psychotherapist. The author provides an historical background to the idea of observation, followed by an account, with detailed examples, of the nature of infant observation and the observational method as taught and practised at the Tavistock Clinic, London since the late 1940s, and subsequently in many other training institutions. Here the themes of Bick and Bion are constantly interrelated such that the prototype or model for the creation of emotional meaning and thought can be appreciated and learning from experience can take place.  相似文献

The subject of dream telepathy (especially patients' telepathic dreams) and related phenomena in the psychoanalytic context has been a controversial, disturbing ‘foreign body’ ever since it was introduced into psychoanalysis by Freud in 1921. Telepathy ‐ suffering (or intense feeling) at a distance (Greek: pathos + tele)‐is the transfer or communication of thoughts, impressions and information over distance between two people without the normal operation of the recognized sense organs. The author offers a comprehensive historical review of the psychoanalytic literature on this controversial issue, beginning with Freud' years‐long struggles over the possibility of thoughttransference and dream telepathy. She then describes her own analytic encounter over the years with five patients' telepathic dreams' dreams involving precise details of the time, place, sensory impressions, and experiential states that the analyst was in at that time, which the patients could not have known through ordinary sensory perception and communication. The author's ensuing explanation combines contributory factors involving patient, archaic communication and analyst. Each of these patients, in early childhood, had a mother who was emotionally absent‐within‐absence, due to the absence of a significant figure in her own life. This primary traumatic loss was imprinted in their nascent selves and inchoate relating to others, with a fixation on a nonverbal, archaic mode of communication. The patient's telepathic dream is formed as a search engine when the analyst is suddenly emotionally absent, in order to find the analyst and thus halt the process of abandonment and prevent collapse into the despair of the early traumatization. Hence, the telepathic dream embodies an enigmatic ‘impossible’ extreme of patient‐analyst deep‐level interconnectedness and unconscious communication in the analytic process. This paper is part of the author's endeavour to grasp the true experiential scope and therapeutic significance of this dimension of fundamental patient‐analyst interconnectedness.  相似文献

Infants’ procedural pain and parents’ treatment room anxiety has been largely ignored in the research and clinical domains. To understand and manage infant procedural pain, it is essential to examine the correlates and potential predictors of this pain. Given that parent anxiety is a strong predictor of preschoolers’ procedural anxiety and pain, it is likely that parents play a role in infants’ distress during medical procedures. The purpose of this study was to thoroughly examine parent anxiety and its effects on infant procedural pain for 37 parent-infant dyads. Results demonstrated that only parent self-report measures were intercorrelated and several measures of parent distress correlated with measures of infant distress. Treatment implications and recommendations for future research are discussed.This article is based on the master's thesis of the first author under the direction of the second, at West Virginia University.  相似文献
