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).

EXPANDING INFANT MENTAL HEALTH TREATMENT SERVICES TO AT‐RISK PRESCHOOLERS AND THEIR FAMILIES THROUGH THE INTEGRATION OF RELATIONAL PLAY THERAPY

The expansion of infant mental health (IMH) to at‐risk preschoolers and their families has contributed to the integration of relational play therapy (RPT) into IMH treatment services for this population. Integrating RPT allows access to specialized play and expressive techniques specific to preschool and family development, which improves the clinical ability to meet the multiple and complex needs of at‐risk parent–child dyads and their families. This article will examine the RPT literature and explore the similarities and differences between IMH and RPT. In addition, two case studies will highlight a five‐phase, integrative clinical‐treatment process and provide insight into how IMH clinicians are integrating RPT models and maintaining adherence to the IMH treatment approach.     

Using psychoanalytic concepts to inform interpretations and direct interventions with a baby in working with infants and parents

Abstract

How can some classical Freudian concepts such as defense, transference, infantile sexuality, and the role of the body ego and superego in the first year of life be applied to help the analyst working with parent–infant dyads? The case of a newborn that could not look at her mother, who did not feel empathy towards this child conceived as a result of an egg donation, was understood using Winnicott’s notion of early superego and the lack of libidinal pleasure. The notion of defenses towards primitive anxiety and the role of unconscious maternal functioning were helpful in helping the child as well as the parents to regulate their interactions.     

Coordination of Emotions in Mother–Infant Dialogues

Eleven infant–mother dyads in Crete were videod during spontaneous interactions at home, from the second to the sixth month of life. Micro‐analysis was used to investigate‘coordination'and ‘non‐matching’ of facial expressions of emotion. ‘Emotional coordination’ was evaluated with four measures: matching of facial expressions, completion when one responded to the other with ‘pleasure’ or ‘interest’, synchrony by matching frequency of change or rhythm of emotional expressions, and attunement when shifts of emotional intensity of the two partners were in the same direction.‘Emotional non‐matching'was coded when neither the infant nor the mother showed interest in interacting with the other. In emotional coordination or non‐matching between mother and infant, who performed first was also recorded. We obtained evidence of emotional matching, synchrony, and attunement. Importantly, the probability of emotional non‐matching by the infant was higher than the probability of emotional matching and completion, indicating a tendency for thoughtful attention or playful rivalry in the responses of infants, who also initiated emotional matching, completion, and non‐matching more frequently than mothers. The probability of expression of emotional matching, completion, and non‐matching changed with age. Both mothers and infants act to obtain sympathetic complementarity of feelings and co‐operative inter‐synchrony of actions. Copyright © 2016 John Wiley & Sons, Ltd.     

婴儿图式及其加工的性别差异

婴儿图式 (baby schema, or Kindchenschema) 是指人们对一系列婴儿特征的一种心理表征, 这些特征包括婴儿所特有的高额头、大眼睛和圆脸蛋等知觉特征。婴儿图式可以诱发人们的积极情绪, 并引起关爱、照顾婴儿的行为, 从而满足个体生存以及繁衍的需要。对婴儿面孔的加工存在性别差异, 女性对婴儿特征比男性更敏感, 原因可能有四种：大脑结构的不同、女性独有的情绪反应、女性生殖激素的影响和早期环境的影响。未来的研究可以进一步揭示婴儿图式的特异性神经机制, 并从性别差异入手, 进一步探讨母爱与婴儿图式的相互作用。     

Infant‐holding biases in mothers and affective symptoms during pregnancy and after delivery

Several authors have reported that participants have a leftward bias when holding a newborn or young infant. Our study of mothers met before and after their infant's birth sought to ascertain whether particular combinations of affective symptoms (depression, anxiety) and holding positions (horizontal versus vertical) were related to holding‐side biases. Our results showed that (a) mothers displayed a significant leftward (71%) holding bias, (b) mothers with affective symptoms held their newborn on the right side and more frequently in the vertical position, and (c) hemispheric specialization for perceiving visual emotions had no significant effect on the holding‐side biases of new mothers. These results suggest that maternal affective symptoms have a dominant effect on the determination of holding‐side preferences, when associated with a particular holding position.

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。     

肺功能检查对婴幼儿哮喘诊断的价值

如何对婴幼儿哮喘进行早期诊断和进行早期干预已成为目前儿童哮喘防治的主要话题。随着肺功能检测技术的进步,临床上已有多项肺功能检测技术可应用于婴幼儿。正确地理解和掌握这些检测技术可为婴幼儿哮喘的诊断和鉴别诊断提供重要依据。本文对这些不同检测技术的原理、参数及其临床意义进行了阐述。
