Visual exploration of reaching space during left and right arm movements in 6-month-old infants

Infant's manual laterality and eye-hand coordination emerge during the second part of the first year of life with the development of reaching. Nevertheless, little is known about the potential asymmetric characteristics of this coordination. The aim of this study was to describe visuo-spatial exploration in 6-month-old infants during reaching, according to the hand used. More specifically, we examined if the use of the left or the right hand was linked to a specific type of visual exploration. Gaze direction during goal-directed reaching towards an object placed on the table was measured with a remote ASL 504 eye tracker (Bedford MA). Twelve babies aged 6 months were observed during six reaching sessions, alterning three sessions with an object on the left side of the subject and three with an object on the right side. Gaze direction and some hand variables (hand activity, hand opening and hand position from the body) were coded with The Observer software. Results showed that babies visually explore their reaching space differently according to the hand used: they look more at the object when they use their right hand and more around the object when they use their left hand; they also look more often at their left hand than at their right one. These results suggest that an asymmetric visuo-manual coordination exists as early as 6 months: vision seems to support (1) left hand during reaching for evaluate distances from object to baby by means of visual feedbacks and (2) right hand for identify what sort of object is. Results are discussed in light of manual specialization and specific hemispheric skills at this age.     

Stratégies et réactions des victimes et de leur entourage face au harcèlement scolaire : une étude rétrospective

The negative consequences faced by students who are victims of school bullying are clearly documented. Nevertheless, few studies have examined victim's reactions and strategies to cope with bullying. Yet a better understanding of these reactions would allow a better support from health professionals and to improved prevention actions. This study aims to explore the victim's coping strategies through the content-analysis of 32 interviews conducted with former victims. Given their decisive influence on the bullying's situation, spontaneous or requested reactions of peers, teachers and parents are examined as well. To include these two aspects in a common theoretical framework, this research proposes to combine two distinct approaches: the coping strategies and the Participant Role Approach (Salmivalli, 2010; Salmivalli et al., 1996). The efficiency of each highlighted strategy is analysed and discussed regarding current scientific knowledge. Results suggest that victims generally experiment a large panel of reactions and strategies to cope with bullying. Nevertheless, few of these strategies seem to have an effect on bullying itself, but some can improve the emotional well-being of the victims. Victims who attempted to be liked by their bullies by changing their own behaviour reported no improvement of their relations with the bullies, neither did the ones who used humour in order to get closer to bullies. Bullies didn’t get tired when victims passively endured the bullying, hoping that it would stop by itself. Stand up (verbally or physically) to the bully led to increased bullying (one situation excepted). Physical avoidance of bullies (e.g. staying in classroom during playtimes) allowed some victims to temporarily reduce their emotional distress. Several victims experimented positive interactions with peers in extra-curricular activities (e.g. sport, art, scouting) that helped them recovering confidence in their social skills. Most of victims sought social support at one point of the bullying time. The efficiency of this strategy entirely belongs to the warned person's reaction and is thus highly variable. Based on participants’ report, only increased connectedness with a peer could have an impact on the bullying behaviour through a better integration in the peer-group. On the contrary, parents and teachers’ reactions are often perceived by the victims as not appropriate and as leading to a worse situation. In terms of practical implications, these results highlight the importance of raising teachers and parents’ awareness of the bullying, as well as the significance of the peers group dynamic. Following-up any bullying situation observed or reported in the school would probably help ensuring relevant interventions.     

SCIENCE,RELIGION, AND ITALY'S SEVENTEENTH‐CENTURY DECLINE: FROM FRANCESCO DE SANCTIS TO BENEDETTO CROCE

Historians have often argued that from the mid‐sixteenth century onward Italian science began to decline. This development is often attributed to the actions of the so‐called Counter‐Reformation Church, which had grown increasingly intolerant of novel ideas. In this article, I argue that this interpretation of the history of science is derived from an Italian liberal historiographical tradition, which linked the history of Italian philosophy to the development of the modern Italian state. I suggest that although historians of science have appropriated parts of this distinctive narrative to underpin their account of Italy's seventeenth‐century scientific decline, they have not always fully appreciated its complexity. In this article, I consider the work of two scholars, Francesco de Sanctis and Benedetto Croce. Both explicitly suggested that although the actions of the Church caused Italy to enter into a period of decline, they in fact argued that science represented one of the few areas in which Italian intellectual life actually continued to thrive.     

Vocal responsiveness of preterm infants to maternal infant-directed speaking and singing during skin-to-skin contact (Kangaroo Care) in the NICU

Vocalizations of full-term newborns occur in a short latency time during the neonatal period. Contingent response time of preterm babies is still unknown. An increase of preterm babies’ vocalizations following exposure to parental speech was also observed. Mothers and babies co-modulate their vocalizations in preterm dyads. Purpose: To observe temporal features of maternal and infants’ vocalizations in speaking and singing conditions in preterm dyads. Methods: In a NICU mothers (N = 36) were invited to speak and to sing to their preterm infants during Kangaroo Care. Microanalysis of temporal units were performed with ELAN Software. Results and conclusions: Preterm infants vocalize less often while their mothers speak and sing than during baseline and their vocalizations tend to be more alternating in the speaking condition and more overlapping in the singing condition. It is also concluded that preterm infants take more time to respond to maternal speaking than to maternal singing.     

Sex differences in the development of physical aggression: An intergenerational perspective and implications for preventive interventions

This article reviews the state of knowledge on the development of chronic physical aggression (CPA), with the aim of identifying the most effective prevention strategies. We specifically focus on the early development of physical aggression, on sex differences in the use of physical aggression, and on the transmission of behavior problems from one generation to the other. The body of research on the development of CPA from the past three decades that we review shows increasing evidence that its prevention requires a long-term biopsychosocial developmental approach which also must include an intergenerational perspective. Recent genetic and epigenetic research has indicated that there are both important genetic and environmental effects on gene expression which start at conception. We conclude that one of the most effective strategies to break the intergenerational transmission of CPA involves giving long-term support to pregnant women with a history of behavior problems, their spouse, and their offspring.     

Reproductive justice and support for young fathers

The current article addresses the interests and contributions of fathers to child development and well-being within a reproductive and social justice framework. We present an overview of research on the role of fathers in the lives of children from the prenatal period through early childhood, with an emphasis on fathers as partners and caregivers in promoting the reproductive health and safety of women and the healthy development of young children. We explore especially the challenges of young, at-risk fathers as well as system and practice opportunities that support their contributions as partners and parents. Our goal of the article is to extend the discourse on reproductive and social justice to include the shared responsibility of all parents and facilitate circumstances whereby children experience the support needed to become nurturing caregivers for the next generation.     

Maternal depression and infant attachment security: A meta-analysis

The purpose of this study is to clarify the magnitude of the association between maternal depression and infant attachment nonsecurity, and to identify possible moderators of this relationship. An extensive literature search was conducted using multiple databases of both published and unpublished studies. A meta-analysis was conducted to determine the relationship between maternal depression and infant attachment security and to establish the effect size. The main findings from this meta-analysis, which included 42 studies, indicate that there is a small, yet significant, relationship between maternal depression and infant attachment nonsecurity. The rate of nonsecurity in infants of mothers with depression was approximately 20% higher than expected rates in a nonclinical population, and the association between depressive symptoms and nonsecurity was small, but significant. Infants of mothers with depression were nearly twice as likely to have a nonsecure attachment than were infants of healthy mothers. Depression measure and maternal sample source were identified as significant moderators of the odds ratio effect size. Results of this study demonstrate that there is a significant relationship between maternal depression and infant attachment nonsecurity, and suggest that interventions that focus on both maternal mental health and the attachment relationship are warranted.
