Children's performance on cognitive tasks is often described in categorical terms in that a child is described as either passing or failing a test, or knowing or not knowing some concept. We used binomial mixture models to determine whether individual children could be classified as passing or failing two search tasks, the DeLoache model room…

Previous research indicates learning words facilitates categorisation. The current study explores how categorisation affects word learning. In the current study, we investigated whether learning about a category facilitates retention of newly learned words by presenting 2-year-old children with multiple referent selection trials to the same object…

This study examined the longitudinal relations of mother-child affect exchanges at 18?months with children's mastery motivation at 39?months. Observation and questionnaire data were collected from mother-child dyads when children were 18?months; 43 mothers again rated their children's mastery motivation at 39?months. Results suggested…

Maternal self-efficacy (MSE) has been shown to be important, yet little is known about how it develops over time and whether increasing knowledge about child development and parenting results in feeling more efficacious, especially for first-time mothers. Furthermore, research is lacking about whether increased maternal self-efficacy results in…

Two recent advances in the study of fearful temperament (behavioural inhibition) include the validation of dysregulated fear as a temperamental construct that more specifically predicts later social withdrawal and anxiety, and the use of conceptual and statistical models that place parenting as a mechanism of development from temperament to these…

This study examined the extent that inhibition among familiar peers was related to inhibition among unfamiliar peers versus exclusion by familiar peers at 2?years of age. Peer inhibition at 2?years of age was assessed by both mothers and teachers on versions of the Behavioral Inhibition Questionnaire and the Preschool Play Behavior Scale (N?=?141…

This longitudinal study (n?=?106) examined associations between temperament, attachment, and styles of compliance and noncompliance. Infant negative temperamental reactivity was reported by mothers at 3, 5 and 7?months. Infant attachment was assessed (Strange Situation) at 12 (mothers) and 14?months (fathers). Toddlers' styles of…

This research investigated the developing inter-relationships between language, graphic symbolism and symbolic play both concurrently and longitudinally from the fourth to the fifth year of childhood. Sixty children ("n"?=?60) aged between 3 and 4?years completed multiple assessments of language and assessments of graphic symbolism,…

Evaluative food categories are value-laden assessments, which reflect the healthfulness and palatability of foods (e.g. healthy/unhealthy, yummy/yucky). In a series of three studies, this research examines how 3- to 4-year-old children (N?=?147) form evaluative food categories based on input from external sources of information. The results…

The development of proficient communication skills in infants and toddlers is an important component to child development. A popular trend gaining national media attention is teaching sign language to babies with normal hearing whose parents also have normal hearing. Thirty-three websites were identified that advocate sign language for hearing…

Rapid changes in language skills and social competence, both of which are linked to sensitive parenting, characterize early childhood. The present study examines bidirectional associations among mothers' sensitive parenting and children's language skills and social competence from 24 to 36?months in a community sample of 174 families. In…

Children's talk about the mind has been scarcely studied in non-English speakers. For this reason, this longitudinal study documents age-related changes in German-speaking children's internal state language. At 24, 30 and 36?months, children were administered general language tests and their internal state vocabulary levels were obtained…

This longitudinal assessment concentrated on the relation between the home literacy environment (HLE) and early language acquisition during infancy and toddlerhood. In study 1, after controlling for socio-economic status, a broadly defined HLE predicted language comprehension in 50 infants. In study 2, 27 children returned for further analyses.…

Myriad studies support a relation between parental beliefs and behaviours. This study adds to the literature by focusing on the specific relationship between parental goals and their communication with toddlers. Do parents with different goals talk about different topics with their children? Parents' goals for their 30-month olds were gathered…

Deficits in executive function, and in particular, reduced capacity to inhibit a dominant action, are a risk factor for externalizing problems (EP). Inhibitory control (IC) develops in the later preschool and early childhood periods, such that IC might not regulate EP in toddlers and younger preschoolers. Aggression was observed during peer play…
