This study used an ethological approach to explore the behavioural adaptation of nineteen infants during their first six weeks in Residential Care (RC), or a Foster Family (FF) or an Infant-Mother Centre (IMC). Direct observations were conducted once a week at bath time. Observed behaviours were: sleep-wake states, visual exploration, motor…

This study used an ethological approach to explore the baby-caregiver dyadic exchanges (Attempted interactions, Triggers, Interactions) of nineteen infants during their first weeks in Residential Care (RC), or a Foster Family (FF) or an Infant-Mother Centre (IMC). Direct observations were conducted at feeding time. Observed behaviours were: baby…

Recent research suggests that infants prefer prosocial behaviour. However, some studies have failed to report this preference, raising the question of which specific parameters allow it to be observed. We attempted to answer this question by investigating whether the preference varies (1) with age (by testing infants aged 6, 12 and 18 months), (2)…

When children are confronted with an emotional problem, affective flexibility mobilizes their cognitive and emotional resources to optimally address it. We investigated the contribution of executive functions to cognitive and affective flexibility in preschoolers. We assessed affective flexibility in 67 preschoolers (30 girls; M[subscript months]…

Iconic gestures illustrate complex meanings and clarify and enrich the speech they accompany. Little is known, however, about how children use iconic gestures in the absence of speech. In this study, we used a cross-sectional design to investigate how 3-, 4- and 5-year-old children (N = 51) communicate using pantomime iconic gestures. Children…

The role of language as a tool to support the self-regulation has been widely studied, yet there is little evidence on the role of prelinguistic communication in the early development of self-regulation. To address this gap, we developed behavioural indicators of preverbal cognitive self-regulation, and described how can parents support it through…

Babysign classes are increasingly popular across the UK. Benefits are said to include increasing child vocabulary, reducing frustration, and improving parent-child relations. A further relationship between the use of babysign and maternal mind-mindedness (MM) has been suggested. It was hypothesized here that parents choosing babysign classes would…

Based on interviews with 120 children ranging from age 3 to 12, legal interviewers rated the grade school and middle school age children as competent and as understanding the meaning of lying. The interviewers rated the grade school children as more credible "witnesses in court" than either the preschool or the middle school age…

This longitudinal and naturalistic study investigated fathers' and infants' emotional expressions during free infant-father "protoconversation" and the preceding/following pauses. Eleven infant-father dyads were observed during spontaneous interactions at home, from the second to the sixth month after birth. Micro-analysis of infant and…

In this study, the effects of eliciting positive and negative emotions on various cognitive functions of four- to five-year-old preschool children were examined. Emotions were elicited through presentations of "happy" and "sad" video clips, before the children performed the cognitive tasks. Behavioural (facial expressions) and…

Cultural display rules govern the manifestation of emotional expressions. In compliance with display rules, the facial expressions displayed (i.e. apparent emotion) may be incongruent with the emotion experienced (i.e. real emotion). This study investigates Australian Caucasian children's understanding of display rules. A sample of 80 four year…
