Increasing amounts of screen time among young children has become a growing concern. Childcare centres maybe one important setting to intervene. This study aimed to examine the prevalence of screen time and screen time policies within childcare centres as well as the association between these policies and screen time among toddlers (19-35 months)…

Whether high quantities of center-based care cause behavior problems is a controversial question. Studies using covariate adjustment for selection factors have detected relations between center care and behavior problems, but studies with stronger internal validity less often find such evidence. We examined whether within-child changes in hours in…

Around the world, musical engagement frequently involves movement. Most adults easily clap or sway to a wide range of tempos, even without formal musical training. The link between movement and music emerges early--young infants move more rhythmically to music than speech, but do not reliably align their movements to the beat. Laboratory work…

Four experiments examined Canadian 2- to 3-year-old children's (N = 224; 104 girls, 120 boys) thoughts about shared preferences. Children saw sets of items, and identified theirs and another person's preferences. Children expected that food preferences would be more likely to be shared than color preferences, regardless of whether the items were…

This study tested a 5-year sequential mediation model linking paternal mind-mindedness in toddlerhood to child early academic achievement through a developmental process unfolding in the preschool years. A sample of 128 mostly White middle-class families (68 girls) living in Montreal, Canada was assessed for paternal mind-mindedness when children…

The current study examined the interaction between maternal depressive symptoms and child temperament in predicting subsequent child language skills. Participants were 252 mother-child dyads recruited from the All Our Families longitudinal cohort, a primarily middle-class sample (62.9% completed postsecondary education) from Alberta, Canada (90.5%…

Background: Child care centers are important for children's behaviors. Aims: To examine the cross-sectional associations between child care environmental characteristics and physical activity and sedentary time in children. Methods: Participants were 124 toddlers and 118 preschoolers from 19 centers in Alberta and Ontario, Canada, in the…

This study aimed to test a 5-wave sequential mediation model linking maternal mind-mindedness during infancy to children's school readiness in kindergarten through a serial mediation involving child language and effortful control in toddlerhood and the preschool years. Among a sample of 204 mother-child dyads, we assessed maternal mind-mindedness…

In December, 2013, revised Alberta child care accreditation standards were released by the Alberta Government in Canada that included a new standard for physical activity and sedentary behavior in accredited child care settings. The main purpose of this study was to examine the effectiveness of the new accreditation standard in increasing physical…

A growing body of theoretical and empirical work has been attempting to answer the questions of how and how much of the effects of children's early experience may depend on their inner characteristics. Theory and evidence suggest that some children, notably those with difficult temperaments, are more susceptible to both negative and positive…

Observed 32 preschoolers' interactions with their toddler siblings. Preschoolers' references about emotions were more likely to be about the toddler than the self. Preschoolers who were skillful perspective takers talked more about internal emotional states and more frequently about the toddler and themselves than did poor perspective takers. (BC)

Toddlers (2 to 3 years) and preschool children (5 to 6 years) were repeatedly presented with a six-tone melody, then tested for their discrimination of a variety of pattern features, including the specific component frequencies, successive intervals, and general melodic contour. To manipulate the information-processing demands of the task, the…

Addressing methodological limitations, Study One compared parent-child interactions of normal and language-delayed children; Study Two investigated whether mothers adjust the length of their utterances to the child's ability to comprehend or to produce language; Study Three probed interactional variables associated with variations in the…

Examines the development of children's understanding of the difference between "want" and "need" in two different experiments. The first experiment required the children to respond verbally in choosing between the two concepts; the second required them to give an object to one of two characters who had made a request using…
