DEVELOPMENT OF THE PARENT‐CHILD PLAY SCALE FOR USE IN CHILDREN WITH FEEDING DISORDERS

The Parent‐Child Play Scale was developed as a scale that complements the Parent‐Child Feeding Scale, created by I. Chatoor et al. (1997), to evaluate mother–infant/toddler interactions in two different caregiving contexts of a young child's everyday life, specifically play and feeding. This Play Scale can be used with infants and toddlers ranging in age from 1 month to 3 years and provides reliable global ratings of mother–child interactions during 10 min of videotaped free‐play in a laboratory setting. The scale consists of 32 mother and infant/toddler interactive behaviors which are rated by trained observers from videotaped observations. Four subscales are derived: Dyadic Reciprocity, Maternal Unresponsiveness to Infant's/Toddler's Cues, Dyadic Conflict, and Maternal Intrusiveness. Construct validity and interrater and test‐retest reliability of the Play Scale have been demonstrated. This Play Scale discriminates between children with and without feeding disorders as well as between children with different subtypes of feeding disorders as defined by the Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood, Revised (DC:0–3R) (Feeding Disorder of State Regulation, Feeding Disorder of Caregiver‐Infant Reciprocity, and Infantile Anorexia). It can be used for research or clinical practice in the diagnosis and treatment of early feeding problems, to assess the pervasiveness of mother–infant/toddler difficulties and to monitor changes following therapy.     

INTERFACING INFANT MENTAL HEALTH KNOWLEDGE: PERSPECTIVES OF SOUTH AFRICAN SUPERVISORS SUPPORTING LAY MOTHER–INFANT HOME VISITORS

This article is part of a project investigating the interfacing of clinically and research‐generated knowledge in the field of infant mental health (IMH) with local cultural models of child care and development. The article explores the experiences and challenges reported by psychology‐trained supervisors in supervision with local, lay, trained home visitors. Supervisors and supervisees were drawn from two early intervention programs which apply relational IMH mental health models in socioeconomically deprived townships in South Africa. Literature that considers supervisors’ experiences of conducting supervision with lay counselors has been limited, and even more so in settings where there are marked cultural and contextual differences between supervisors and supervisees. These differences pose particular challenges regarding the finding of a shared theoretical understanding of the work as well as to the establishment of a secure working alliance. While it was found that psychoanalytic and attachment‐informed theories of infant development are applicable in these South African settings, differences in race, language, education, socioeconomic status, and culture between supervisors and supervisees challenge the supervisor–supervisee relationship and require psychological processing and creative solutions to ensure integrity in the application of the model.     

感知社会支持与学生学业成就关系的元分析：学习投入的中介作用

学业成就是衡量学生学习认知能力和检测其学习效果的重要指标,受到感知社会支持和学习投入等因素的显著影响,先前的研究已经考察了这两个因素对学业成就的共同作用机制,但感知社会支持与学业成就的关系强度不明,且尚不完全清楚中介效应、调节效应对二者关系的影响。因此当前研究采用元分析方法检验效应量的可靠性、学习投入的中介效应以及一系列调节效应。研究共纳入符合要求的原始文献41篇,含78个研究。结果发现：(1)感知社会支持及子类型与学业成就呈现显著的正相关,但效应值偏小,即二者之间存在的是弱相关。此外,感知社会支持及子类型显著正向预测学习投入,且对学习投入的效应量高于对学业成就的效应量。(2)学段仅对感知教师支持的调节效应显著,学业成就指标调节了感知社会支持及子类型与学业成就之间的关系,而经济水平和文化背景的调节效应不显著。(3)学习投入在感知社会支持及子类型对学业成就的影响中起到部分中介作用,且中介效应只存在于初中群体,在高中群体中介效应不显著。     

Infant irritability and early mother–infant reciprocity patterns

This study investigated how various forms of neonatal irritability (at 3 days) and irritability at 10 weeks are related to reciprocal interactions between mothers and their infants. Fifty‐six fullterm, first‐born male infants were examined using the Neonatal Behavioral Assessment Scale (NBAS‐K) at 3 days postpartum. Each infant was rated for irritability to aversive stimuli, general irritability, consolability and responsiveness to visual–auditory stimuli. At 10 weeks of age, during a home visit, mother–infant reciprocity was scored for gaze, smile, vocalization and hold behaviors. Based upon maternal reports and behavioral observations, infant irritability was scored at 10 weeks using the NBAS‐K scoring system. Findings revealed that: (1) there were two distinct forms of reciprocity: social and physical; (2) general irritability at 3 days was negatively related to reciprocal hold interaction and positively related to reciprocal social interaction at 10 weeks, and (3) neonatal irritability to aversive stimuli (at 3 days) was positively related to subsequent reciprocal social interaction. Regression analyses showed that neonatal variables were the foremost predictors of reciprocal hold at 10 weeks. Findings are discussed in terms of (1) the need to differentiate between social and physical behavioral patterns, and (2) time‐lag effects with respect to mother–infant interactions.

The prosodic expression of anger: Differentiating threat and frustration

A theory relating aggression and the pitch of vocalizations [Ohala, 1983, 1984] predicts that the expression of anger in humans should have a low pitch; however, experimentally anger is found to have a high pitch. A possible resolution of this discrepancy is that there are two different prosodic expressions of anger, one with low pitch and one with high pitch. To investigate this possibility, 27 different expressions of the phrase “Don't do that” were tape-recorded. Subjects first rated how angry each utterance sounded and then categorized each utterance as expressing either frustration, threat, disgust, advice, or emotional neutrality. Some utterances were rated as angry and categorized as frustration; other utterances were also rated as angry, but categorized as threat. Frustration correlated with higher fundamental frequency (F₀). Threat did not correlate with lower F₀, but it correlated with lower perceived pitch.     

Do early parental postnatal depression,attachment style and perceived social support affect neurodevelopmental outcomes of premature infants?

BackgroundThe birth of a premature infant is both a stressful event for both parents and associated with an increased rate of postnatal depression (PND). Additionally some mothers may have delayed feelings of attachment to their babies because of the medical procedures or possible medical complications. Social support is known as an important factor for well-being in the postnatal period. However there is scarce data about these factors for fathers. We aimed to identify the impact of parental PND, attachment style and social support on premature infant development considering the prematurity degree and risk groups.MethodsThis prospective study was conducted by including 96 infants who were born preterm. Mothers and fathers were given Edinburgh Postnatal Depression Scale (EPDS), Adult Attachment Style Scale (AASS), and Multidimensional Scale of Perceived Social Support (MSPSS) to fill out when their infants’ corrected age was 3 months. The developmental evaluation was conducted with Bayley III at the corrected 6 months and 18 months of age.ResultsPostnatal depression scores were more in mothers than fathers, the rates of secure attachment and social support were similar between mothers and fathers. Factors associated with the neurodevelopmental outcomes including prematurity degree and risk groups, EPDS, AASS and MSPSS scores were analyzed for both parents. In multivariate analysis, fathers’ depression scores were inversely associated with cognitive development (p = 0.030, R² = 0.080, B=-0.283) and mothers’ anxious/ambivalent attachment style was inversely associated with language development (p = 0.011, R² = 0.108, B=-0.329) at the age of corrected 6 months old.ConclusionsOur findings underscore that the efforts to improve developmental outcomes of premature infants should include parental well-being taking into account new fathers’ depressive symptomatology and maternal anxious/ambivalent attachment.     

Intentional action processing across the transition to crawling: Does the experience of self-locomotion impact infants’ understanding of intentional actions?

Motor developmental milestones in infancy, such as the transition to self-locomotion, have cascading implications for infants’ social and cognitive development. The current studies aimed to add to this literature by exploring whether and how crawling experience impacts a key social-cognitive milestone achieved in infancy: the development of intentional action understanding. Study 1 used a cross-sectional, age-held-constant design to examine whether locomotor (n = 36) and prelocomotor (n = 36) infants differ in their ability to process a failed intentional reaching action. Study 2 (n = 124) further probed this question by assessing how variability in locomotor infants’ experience maps onto variability in their failed intentional action understanding. Both studies also assessed infants’ tendency to engage in triadic interactions to shed light on whether self-locomotion impacts intentional action understanding directly or indirectly via changes in infants’ interactions with social partners. Altogether, results showed no evidence for the role of self-locomotion in the development of intentional action understanding. Locomotor and prelocomotor infants did not differ in their failed action understanding or levels of triadic engagement (Study 1) and individual differences in days of crawling experience, propensity to crawl during play, and maximum crawling speed failed to predict infants’ intentional action understanding or triadic engagement (Study 2). Explanations for these null findings and alternative influences on the development of intentional action understanding are considered.     

Revisiting the roots of attachment: A review of the biological and psychological effects of maternal skin-to-skin contact and carrying of full-term infants

During the early period of hypothesis building and empirical testing of attachment theory, a major emphasis was placed on mother-infant physical contact. In spite of this, mother-infant contact has received scant attention amongst attachment and child development researchers in the past decades. Here, a brief theoretical framework for mother-infant contact is presented, drawing on animal studies as well as human studies of preterm infants and neonates. Salient mechanisms may include an extended sensitive period during early infancy, requiring specific somatosensory stimuli for bio-behavioral homeorhesis; oxytocinergic and epigenetic pathways; kinesthetic stimuli and face-to-face proximity allowing for increased social interaction. Studies of extended human mother-full-term infant physical contact have demonstrated positive effects in multiple domains. For infants, these include sleep organization, temperature and heart rate regulation, behavioral response, crying/colic, socio-emotional development, attachment quality, speech development opportunities and mother-child interactions. For mothers, studies demonstrate improved depressive symptomatology, physiological stress regulation, contingent responsivity, breastfeeding and mother-child interactions. Parent-infant attachment quality has gained prominence as a trauma-resilience factor as well as a predictor of adult physical health. The potential role of mother-infant contact as an attachment promoting intervention as well as future research subjects are discussed. Current evidence supports the original attachment research that early maternal touch provision may influence infant socio-emotional development and attachment quality, with positive implications for mother-child relationship functioning.     

Substance use and mothers’ neural responses to infant cues

Substance use may influence mothers’ responsiveness to their infants and negatively impact the parent–infant relationship. Maternal substance use may co-opt neural circuitry involved in caregiving, thus reducing the salience of infant cues and diminishing the sense of reward experienced by caring for infants. Gaps in understanding exist with regard to the mechanisms by which substance use operates to influence mothers’ processing of infant cues and how this translates to caregiving. Therefore, we examined how substance use might relate to maternal neural responses to infant cues using event-related potentials (ERPs). Substance-using (n = 29) and nonsubstance-using (n = 29) mothers viewed photographs of infant faces and heard recordings of infant vocalizations while electroencephalography was recorded simultaneously. Three specific ERP components were used to examine initial processing of infant faces (N170) and cries (N100), and attentional allocation to infant faces and cries (P300). Substance-using mothers did not discriminate facial affect at early encoding stages (N170), were generally slower to orient to infant cries (N100), showed heightened responses to neutral faces (P300), and failed to adaptively differentiate between high-distress versus low-distress cries (P300). These differences may be important to caregiving behaviors associated with the formation of mother–child attachment. Implications are discussed, as are limitations and future directions.
