We examined whether infants aged 6-8 months show object-based attention using the preferential looking method. In object-based attention, which is a prerequisite function for efficient real-world processing of various stimuli, a target that appears at a cued object is detected and processed faster than a target appearing at an uncued object. We presented 6- to 8-month-old infants with the visual stimuli consisting of two white vertical rectangles side by side, in which a target appearing at 1) the cued location, 2) the end opposite to the cued location, and 3) another rectangle's end following the cue, using an established paradigm, and measured each infant's first saccade to the target...

This exploratory application of the infant simulator with two couples is designed to illustrate individual reactivity and coparenting behaviors in young couples in serious relationships who do not yet have children. A 35-min protocol with standardized onsets and offsets of inconsolable baby cries was used to capture partner's individual behavioral and physiological responses as well as the couple's joint efforts to soothe the crying baby. Task feasibility was demonstrated by couples' persistent and wide-ranging efforts to calm the baby including rocking, feeding, changing, talking to the baby, and singing...

Research has demonstrated that an understanding of and engagement in cooperative activities emerges early in life. However, little is known about the expectations infants hold about the consequences of cooperative action. We demonstrate that 14-month-old infants expect that cooperative partners will share the recently attained cooperative goal instead of keeping it for themselves. Interestingly, this prediction does not hold if infants saw the two individuals work towards individual goals. These findings contribute to the growing body of literature suggesting that infants possess at least a basic understanding of cooperation well before their second birthday...

Infants use others' emotional signals to regulate their own object-directed behavior and action reproduction, and they typically produce more actions after having observed positive as compared to negative emotional cues. This study explored infants' understanding of the referential specificity of others' emotional cues when being confronted with two actions that are accompanied by different emotional displays. Selective action reproduction was measured after 18-month-olds (N = 42) had observed two actions directed at the same object, one of which was modeled with a positive emotional expression and the other with a negative emotional expression...

PURPOSE: To investigate the observation that perpetrators of abusive head trauma engage in repeated shakings because shaking "works" to quiet the infant. METHODS: Sixty first-time parent couples individually cared for a programmable model infant in two consecutive 7-min trials. After six minutes of consolable followed by inconsolable crying, parents selected one of three soothing techniques. For trial one, parents were randomized to a "Successful" or "Failed" Soothing Condition...

The relations among maternal depression risk, maternal mind-mindedness, and infants' attachment behavior were longitudinally examined in a community sample of mother-infant dyads. Maternal self-reported depression risk was measured at the infant ages of 6 weeks, 4 months, and 12 months. Maternal mind-mindedness, assessed from mothers' comments about infants' mental states (e.g., infants' thoughts, desires, or emotions), was measured during mother-infant interactions when infants were 4 months. Infants' attachment behavior was assessed at one year...

The increasing prevalence of postnatal anxiety highlights the need for summarizing the recent research on this condition to inform screening and intervention efforts. This narrative review of the literature was derived from a search on PubMed and PsycINFO for papers published since 2010. The demographic risk factors for postnatal anxiety include being a young mother, having more education and being employed. Childbirth risk factors include being primiparous in one sample and multiparous in another, caesarean delivery, fear of the birth and of death during delivery, lack of control during labor, low self-confidence for the delivery and the delivery staff, and premature delivery...

PURPOSE: Although the negative consequences of maternal depression on infants has been documented in several Western societies, similar studies have not been conducted in Middle-Eastern countries where cultural norms and traditions may differ. The main objective of this study was to determine the risk factors for postpartum depression (PPD) and its relationship to mother -infant bonding in a Lebanese population. METHODS: One hundred and fifty participants were administered the Edinburgh Postpartum Depression Scale (EPDS), and the social support scale at 2-3 days postpartum...

Based on limitations in previous research evidence, we concluded that more research is needed for deeper understanding of how social-emotional and behavioral (SEB) outcomes among infant-toddler-aged children in the general population are associated with early motor development. In this study, we investigated associations between early competencies and problems, as measured by the Brief Infant-Toddler Social and Emotional Assessment (BITSEA), and the timing of achievement of the main gross and fine motor milestones usually attained during the first year of life in a general population context...

Combining the joint attention approaches of Mundy and colleagues' (2007) experimental coding of infants' specific initiating and responding acts and of Bakeman and Adamson's (1986) descriptions of both infants' and mothers' behaviors during joint engagement, this study examined 29 infants' and mothers' initiatives and responses leading to success in achieving joint attention (JA) episodes during naturalistic interactions when infants were 13 and 17 months old. Analyses revealed developmental changes in initiative frequencies and in the origins of JA episodes...

BACKGROUND: Adolescent motherhood is accompanied by a constellation of risk factors that translate into developmental risk for the off-spring. Socioeconomic risk that is associated with adolescent motherhood as well as maternal interactive behaviors may contribute to the impact of adolescent motherhood on children's developmental outcome. OBJECTIVE: Therefore, the aim of the current study was to investigate differences in children's cognitive development between children of adolescent and adult mothers in their first two years of life and to examine whether socioeconomic risk (e...

Recent empirical studies reporting sex differences in attachment relationships have prompted investigators to consider why and under what conditions such results might be observed. This study was designed to explore possibilities of identifying sex differences in the organization of attachment-relevant behavior during early childhood. Observations of 119 children (59 boys) with their mothers and (separately) with their fathers were completed and children were described using the AQS. Results indicated that girls and boys did not differ with respect to global attachment security but at more specific level analyses revealed differences between parents that reflected differences in the behaviors of girls vs...

BACKGROUND: Exposure to HIV during pregnancy is a risks to development. Exposed child should have assessed its development since birth. Alberta Infant Motor Scale is a tool which assess gross motor skills, with easy application and low cost. Up to now, this scale had not proven its validity for the population exposed to HIV. It's necessary to compare its with a gold standard tool, Bayley scale, which assess gross and fine motor skills, has a high cost and longer application time required...
