Sex differences in typical development can provide context for understanding ASD. Baron-Cohen ("Trends Cogn Sci" 6(6):248-254, 2002) suggested ASD could be considered an extreme expression of normal male, compared to female, phenotypic profiles. In this paper, sex-specific M-CHAT scores from N = 53,728 18-month-old toddlers, including n…

The current study examined the relations between individual differences in attention to emotion faces and temperamental negative affect across the first 2 years of life. Infant studies have noted a normative pattern of preferential attention to salient cues, particularly angry faces. A parallel literature suggests that elevated attention bias to…

Typically developing (TD) children refer to objects uniquely in gesture (e.g., point at a cat) before they produce verbal labels for these objects ("cat"). The onset of such gestures predicts the onset of similar spoken words, showing a strong positive relation between early gestures and early words. We asked whether gesture plays 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…

Several challenges arise when researchers or practitioners attempt to assess the literacy skills of toddlers, including a lack of developmentally appropriate measures, toddlers' more limited communication ability, and how literacy is defined in the years before age three. This paper describes four new measures of early literacy development and…

This article discusses how 2-year olds cope with various everyday activities as observed by kindergarten staff from a gender perspective. Everyday activities are part of the daily pedagogical life in a kindergarten and are linked to situations such as meals, dressing and undressing, grooming and potty/toilet training. Data were collected through…

Parents as partners in their children's learning is predicated by a notion of a mutual understanding of the learning as shared by educators. Documenting learning in early childhood education and care (ECE & C) settings has evolved from more traditional developmental approaches to include photographs, artefacts and social stories to make…

Whilst the role of interactive play, thought and language in children's development has been acknowledged, less is known of the role of interactive play, thought and "music." Children's early music-making is both generative and performative in nature and provides a means by which they engage with self and others. Their independent…

Children base trait inferences about people on direct observations of behavior. In some situations, these inferences might conflict with information supplied by others. This study examined 3- to 6-year-olds' willingness to change their own trait attributions about an actor after receiving a consistent or inconsistent trait label from an authority…

This study leverages nationally representative data (N ˜ 6,000) to examine the magnitude of quality differences between (a) formal and informal early childhood education and care providers; (b) Head Start, prekindergarten, and other center-based care; and (c) programs serving toddlers and those serving preschoolers. It then documents differences…

This report investigates tool learning and its relations to executive functions (EFs) in toddlers. In Study 1 (N = 93), 18-, 20-, 22-, and 24-month-old children learned equally well to choose a correct tool from observation, whereas performance based on feedback improved with age. Knowledge transfer showed significant progress after 22 months of…

For more than 20 years, the MacArthur-Bates Communicative Development Inventory (CDI) and its adaptations for languages other than English have been used as reliable measures of infants' and toddlers' early receptive and productive vocabulary size. This article introduces the OZI, the Australian English adaptation of the MacArthur-Bates CDI, now…

Despite the widely-recognized benefits of early childhood experiences in formal settings that enrich the social and cognitive environments of children, many children--particularly infants and toddlers--spend their days in unregulated (or very lightly regulated) "informal" childcare settings. Over half of all one- and two-year-olds are…

Children's frequency of stuttering can be affected by utterance length, syntactic complexity, and lexical content of language. Using a unique small-scale within-subjects design, this study explored whether language samples that contain more stuttering have (a) longer, (b) syntactically more complex, and (c) lexically more diverse utterances than…

Background: Preterm children have an increased risk regarding self-regulation development. Given the strong link between parenting behaviour (i.e., scaffolding and sensitivity) and children's self-regulation, parental training presents a promising way to counteract the negative consequences of preterm birth. Aims: We explored the effectiveness of…
