Towards a broader scope of biomechanics in developmental studies: a commentary on Jensen (2005)

In this article, we discuss where biomechanical analysis can contribute to our understanding of motor development, and more particularly in what ways biomechanics can contribute to (1) explaining the universal sequence in motor milestones; (2) explaining variations in developmental sequence between individuals; (3) understanding the impact of context on the actions of an individual; and (4) understanding, preventing, and managing chronic disabilities. In our view, biomechanics is concerned with the dynamics of the musculo‐skeletal system (MSS) and thus provides insights in the way motion is affected by the activation of muscles and the mechanical interaction between the MSS and the environment. Biomechanical analysis is important in understanding the development of actions that depend on the perceptual‐motor loop although it cannot provide a full account of the changes in the behaviour. The contributions and limitations of specific biomechanical analyses such as the inverse and forward dynamical models are discussed in the light of the article of Jensen (2005).

儿童早期词汇获得的跨语言/文化研究

婴儿词汇学习是国际语言发展研究的前沿领域, 但大多数研究都是以英语婴儿为研究对象。目前国内关于汉语婴儿早期语言发展研究处于起步阶段。由于汉语在词法、句法等方面具有明显的特殊性, 另外, 成人“言语输入”的语用习惯以及非言语线索都会影响婴儿早期词汇学习, 使得不同语言文化下的婴儿呈现不同的单词学习模式。本项目力图从跨语言视角考察汉语和英语婴儿的早期单词学习(包括单词的理解和产生)以及促进婴儿语言发展的成人言语和非言语输入特征。研究将综合采用实验室实验、半结构化实验室观察和量表测量等研究方法, 利用新的研究技术(如习惯化和IPLP), 从多个角度探索婴儿词汇发展, 以及不同语言文化和个体环境对婴儿早期词汇学习的影响, 揭示词汇获得的跨语言一致性和特异性。研究结果有望对儿童的语言学习提供启示。     

The 'self' in analytical psychology: the function of the 'central archetype' within Fordham's model

This paper concerns the self as Fordham came to conceive it after a conceptual analysis of Jung's use of the term. Fordham identified a contradiction in Jung's usage, and resolved it by reserving 'self' for a definition of the psychosomatic entirety of the individual, and using a separate term for referring to expressions of the self in human experience (e.g. symbols). Fordham tentatively suggested that the latter be termed the 'central archetype', although this was neither developed nor dropped. I explore the value of this term from a developmental perspective and, more specifically in terms of the deintegration of psyche out of an early psychosomatic unity. This draws upon infant research and an observation of a 14-month old boy. Finally, further developments are briefly described and illustrated, whereby pre-symbolic expressions of the central archetype become symbolic and come to reflect what was for Jung, the 'ultimate', 'Formation, Transformation, Eternal Mind's eternal recreation'.     

Infant Mental Health assessment: the use of DC 0-3 in an outpatient child psychiatric clinic in Scandinavia

The study focuses on Infant Mental Health data from an outpatient psychiatric clinic using the "Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood" (DC 0-3) and parental questionnaires, CBCL and ITSC. In total, 138 infants (aged 0-3) went through the diagnostic procedure. Sixty-eight per cent were diagnosed within Axis I, with regulatory disorder, disorder of affect and traumatic stress disorder being the most frequent diagnoses. In addition, 48% were classified as having a relationship disorder according to Axis II, with an additional 40% being considered to be at risk of developing a relationship disorder. The mothers' and fathers' ratings of their children's externalized and sensitivity problems were in agreement with the clinicians, but the ratings of internalized problems as well as relationship problems presented a more complex pattern.     

Both maternal sensitivity and atypical maternal behavior independently predict attachment security and disorganization in adolescent mother-infant relationships

Extant theory holds that variation in attachment security is largely determined by caregiver sensitivity whereas disorganization has its roots in atypical interactions that frighten the infant. These hypotheses were confirmed in the current study of a high-risk sample but, contrary to current theory, both atypical maternal behavior and maternal sensitivity were also significant independent predictors of attachment disorganization and security.     

Patterns of maternal responding in postpartum mothers with schizophrenia

Little is known about how schizophrenia might affect how a mother responds to her infant, such as whether responding is reduced or impaired. The aim was to identify, from brief videotaped interactions, whether the responses of mothers with schizophrenia were fewer, less positive, more negative, and more ‘abnormal’ than mothers with affective disorder, and whether their infants (mean age: 15 weeks) lacked activity or initiation to which mothers could respond. Mothers with schizophrenia (N = 14) were as responsive as mothers with affective disorder (N = 31), but they showed markedly low positive responsiveness. Only the schizophrenia group exhibited non-responses as a result of being psychologically withdrawn from the interaction, and abnormal behaviors. Inconsistent to our hypothesis, infants in both groups showed similar levels of activity, initiative and negativity. The findings highlight the need for further research to examine the contribution of maternal response impairments to the developmental vulnerability of this genetically high-risk group.     

Infants’ expressive behaviors to mothers and unfamiliar partners during face-to-face interactions from 4 to 10 months

Changes in the organization of infant looking, facial expressions, and vocalizations were examined over age (4, 7, and 10 months) and with different social partners. Although infants at all ages accompanied smiling with looking at both mothers and unfamiliar partners, 7- and 10-month infants accompanied vocalization with looking only when they were with mothers. Seven- and 10-month-olds vocalized with unfamiliar partners only when they were smiling at the same time. When mothers stopped talking, infants reduced smiling significantly at all ages, yet vocalized more at 10 months. In the second half of the first year, there are fundamental changes in the coordination of infant expressive behaviors that reveal a keen attunement to variations in maternal behavior and the familiarity of social partners.     

African-American Women’s Conceptualizations of Health Disparities: A Community-Based Participatory Research Approach

Health disparities among African-American families represent a significant social problem. Nationally, African-American infants have dramatically worse birth outcomes than other racial and ethnic groups. A Community-Based Participatory Research approach was utilized to engage community residents. This study examined participants’ definitions of infant mortality, views on the community impact of infant mortality, and strengths and vulnerabilities in the health care service delivery system. Qualitative data were gathered in a rural North Florida community where health education groups are conducted. Eight focus groups were arranged with African-American women (n = 46), ranging in age from 14 to 35, who were pregnant, parenting children under the age of two. Respondents poignantly described personal experiences of loss associated with infant mortality. They indicated awareness of problems related to lack of accessibility and availability of medical and social services. The use of social-ecological theory and implications for policy and social justice are discussed.     

七氟醚与氯胺酮做基础麻醉在婴幼儿先天性唇腭裂手术中的应用比较

为了寻找婴幼儿先天性唇腭裂手术比较理想的基础麻醉方式,将该类手术患儿60例随机均分为氯胺酮肌肉注射基础麻醉组（K组）和高浓度七氟醚吸入基础麻醉组（S组）。患儿入手术室后常规监测生命体征,记录其哭闹时间、睫毛反射消失时间和疼痛反射消失时间,观察基础麻醉期间患儿的合作情况和有无并发症的发生。术后随访并发症的发生情况。S组与K组患儿相比,哭闹时间、睫毛反射时间、疼痛反射消失时间均显著缩短。K组患儿基础麻醉期间发生的并发症明显多于S组,且．术后呕吐的发生率亦显著高于S组。因此,高浓度七氟醚吸入做基础麻醉是婴幼儿先天性唇腭裂手术时较为理想的基础麻醉方式。
