Reinforcement of vocalizations through contingent vocal imitation

Maternal vocal imitation of infant vocalizations is highly prevalent during face-to-face interactions of infants and their caregivers. Although maternal vocal imitation has been associated with later verbal development, its potentially reinforcing effect on infant vocalizations has not been explored experimentally. This study examined the reinforcing effect of maternal vocal imitation of infant vocalizations using a reversal probe BAB design. Eleven 3- to 8-month-old infants at high risk for developmental delays experienced contingent maternal vocal imitation during reinforcement conditions. Differential reinforcement of other behavior served as the control condition. The behavior of 10 infants showed evidence of a reinforcement effect. Results indicated that vocal imitations can serve to reinforce early infant vocalizations.     

Parenting and Adolescents' Depressive Symptoms: The Mediating Role of Future Time Perspective

This study investigated the relations between maternal and paternal rearing practices and adolescents' depressive symptoms, and whether time perspective in adolescence explains these links. The sample included 306 students (158 girls), aged between 10.83 and 14.42 years. Adolescents completed questionnaires assessing their perceptions of maternal and paternal acceptance and psychological control, and of their future time perspective and depressive symptoms. Adolescents who rated their mothers as more accepting and those who rated their fathers as less psychologically controlling also reported lower levels of depressive symptoms and greater future time perspective. Further, adolescents who had greater future time perspective reported lower levels of depressive symptoms. Finally, time perspective partially mediated the relations of maternal and paternal acceptance, and paternal control with depressive symptoms in adolescence. The findings highlight the unique relations of maternal acceptance and paternal psychological control with adolescents' depressive symptoms, and that future time perspective is one mechanism that might explain why parenting strategies are linked with depressive symptoms in adolescence.     

婴儿气质及母亲的养育态度与亲子日常活动的关系

本研究以430名母亲及其婴儿作为研究对象,应用婴儿气质行为评定量表(Infant Behavior Questionnaires,IBQ)、养育压力量表(ParentingStress Index,PSI)及母亲与婴儿的日常活动问卷对6个月婴儿气质、母亲的养育态度及母亲与婴儿的日常活动进行调查。结果表明婴儿气质中的积极情绪与母亲-婴儿日常活动有显著的正相关关系;母亲的养育态度,主要是母亲对养育困扰的评价,与亲子日常活动中的认知刺激活动呈显著的负相关性;多元回归分析表明母亲的受教育水平在婴儿气质、母亲的养育态度与亲子日常认知刺激活动之间的关系中具有调节作用。     

Maternal expectations about infant development of pre‐term and full‐term infants: a cross‐national comparison

In three European regions (The Netherlands, Northern Italy and Southern Italy) we investigated whether mothers of healthy pre‐term infants (n=92) adjust their expectations for the timing of developmental milestones in the first years of life as compared to mothers of full‐term infants (n=140). We examined whether these adjustments could be seen as reflecting a pessimistic view, as would be predicted from the ‘prematurity stereotype’ perspective. Partial corrections for prematurity were regularly made, but no indications were found for an overly pessimistic view. Moreover, the differences between the regions in the anticipated timing of mastery of milestones were larger than the effects of prematurity. Copyright © 2006 John Wiley & Sons, Ltd.     

Maternal beliefs concerning young children's private speech

The goal of this study was to understand maternal reports, beliefs, and attitudes about their young children's use of private speech. Mothers of 48 children between the ages of 3 and 5 participated in a semi‐structured interview in which they reported on the frequency and context of their child's use of private speech, maternal responses toward such speech use in children, and beliefs about the utility of such speech for children. Interviews were transcribed and responses coded. Mothers also completed surveys on children's self control and parenting style. Results indicated that practically all parents reported that their child engaged in private speech and that such speech was more likely to appear during fantasy play than during problem‐solving activities. Parents varied in their personal responses to children's self talk and, as a group, do not appear to actively discourage or encourage its use. Ignoring/allowing child private speech use was common and this response was positively associated with authoritative parenting. Parental reports of the frequency with which their child talks to himself were negatively associated with parental reports of children's self‐control. Crib speech, or bedtime monologue, was reported to be very common and was negatively associated with children's self‐control and positively associated with children's private speech use. Parents were uniformly positive in their belief that private speech serves important functions and that it helps young children during task activities. Copyright © 2006 John Wiley & Sons, Ltd.     

Maternal sensitivity and behaviour problems in young children with developmental delay

Children with developmental delay are at increased risk for behaviour problems, but little is known about risk and resilience factors. Previous research has established links between maternal sensitivity and behaviour problems in typically developing children, but no studies have examined maternal sensitivity in the development of behaviour problems in children with developmental delay. In this study, we coded videotaped interactions of 30 2‐year‐olds with developmental delay and their mothers using the maternal behaviour Q‐sort and a child behaviour coding system. Mothers completed the child behaviour checklist when their children were 2 and 3 years old. Results revealed significant inverse relations between maternal sensitivity and concurrent and later externalizing problems, and significant positive relations between maternal sensitivity and concurrent observed appropriate behaviour (compliance and social engagement). This study informs developmental theory and identifies an important maternal variable that may reduce the risk of behaviour problems in children with developmental delay.

母亲守门行为与父子依恋的关系：父亲教养投入的中介作用

以597个核心家庭的父亲、母亲和青少年为研究对象,通过问卷调查探讨了母亲守门行为与父子依恋的关系以及父亲教养投入在其中的中介作用。结果表明：（1）母亲开门行为正向预测父子依恋,母亲关门行为负向预测父子依恋;（2）母亲开门行为通过正向预测父亲教养投入的部分中介作用间接预测父子依恋,而母亲关门行为通过负向预测父亲教养投入的部分中介作用间接预测父子依恋。研究结果扩展了母亲守门行为的作用效果研究,对家庭教育实践具有一定的指导意义。     

9-24月龄婴儿母亲敏感性的预防性干预实验

本研究根据依恋理论和相关的干预研究成果编制了母亲敏感性干预手册,并对9-24月龄要儿的母亲实施了预防性干预.有16对母婴对分别进行了家庭录像观察.其中10位母亲作为培训组参加为期两个月的干预,干预目标集中于提高母亲敏感性,并提高母亲与婴儿的互动行为水平.另外6位母亲为对照组.三个月后,干预完成并再次对培训组和对照组进行家庭观察.用AinSwonh母亲敏感性量表和母亲行为Q分类方法分别对两次家庭观察录像进行编码分析.结果表明:培训组在信号敏感、可得、阻碍和接纳四个方面都有改善;该干预模式有效提高了母亲的敏感性.同时,该干预对母婴互动行为水平也略有提高.在文章中讨论了存在的问题和今后的研究方向.     

Maternal speech style with prelinguistic twin infants

The mother–infant communicative speech of a group of mothers of 4‐month‐old first‐born twin infants was compared to the speech of a group of mothers of first‐born singleton infants. Maternal groups were matched on age, education level, mother–infant attachment status and infant gender, and maternal depression was assessed as a control variable. Maternal speech was coded for focus, content, complexity and syntax of mothers' utterances. The findings of earlier studies with toddler age twins, that maternal speech style was more directive and less infant‐focused, were replicated in this prelinguistic period of infancy. Compared to mothers of singletons, mothers of twins used less infant‐focused speech, were less responsive to their infants' cues, and attributed less agency to their infants. Mothers of twins also used fewer questions and requests but did not differ from mothers of singletons in their use of negatives and imperatives. These early differences in the language learning environments of twin and singleton infants may be due to the reduced opportunities that mothers of twins have to establish dyadic communicative routines with their infants and to familiarize themselves with their infants as interactive partners, and may have implications for the early language development of twins.
