Aims: Children with neuromotor delays are at risk for reaching and object exploration impairments, which may negatively affect their cognitive development and daily activity performance. This study evaluated the effectiveness of the Sitting Together And Reaching To Play (START-Play) intervention on reaching-related exploratory behaviors in…

Deixis -- a fundamental part of communication -- involves combinations of speech, gesture and eye-gaze, yet little is known about the temporal dynamics of this coordination. The authors analysed eye-gaze, pointing gestures and verbal productions in 514 deictic episodes during triadic, semi-naturalistic, book-reading sessions performed by Italian…

Research on the effects of nursery school attendance still presents divergent results: a possible explanation is that the effects of child care on development outcomes can be modulated by individual characteristics, such as gender or temperament. In the present study, gender differences in nursery adaptation (evaluated by social skills and…

We collaborated with Early Head Start (EHS) coaches to qualitatively explore the feasibility delivering a professional development approach designed to enhance the quality of conversations in infant-toddler (I/T) classrooms and family child care homes. First, we reviewed empirical literature about oral language discourse skills in infants and…

The study examines phases in developing specification of grammatical marking of emergent clause-combining (CC) as indicative of children's growing ability to integrate two or more independent predications. To this end, both intra- and inter-clausal analyses were applied to all CC utterances produced by three Hebrew-acquiring children aged 2;0-3;0,…

Identification of language disorders in children younger than 3 years remains challenging despite agreement that early intervention improves outcomes. This study of twin language and gesture development substantiated the twinning effect, an unexplained lag in expressive and receptive language seen in twins, for a group of 88, 16- to 18-month-old…

A wealth of research evidences the positive impact of the outdoors for young children. Yet there is little relating to the experiences of babies and toddlers who attend daycare settings. This paper offers new knowledge about outdoor provision for under twos in the English context where there is a lack of explicit policy support for outdoor…

Aim: There is a lack of evidence-based tools for measuring problem-solving in young children with motor delays. The purpose of this study was to evaluate the construct validity and responsiveness of the Assessment of Problem-Solving in Play. Methods: 125 young children (10.72, SD 2.62 months) with mild, moderate, and severe motor delays were…

As the rates of Autism Spectrum Disorder (ASD) increase and early screening efforts intensify, more toddlers with high likelihood of ASD are entering the United States' (US') publicly funded early intervention system. Early intervention service delivery for toddlers with ASD varies greatly based on state resources and regulations. Research…

Associative word learning, i.e., associating a word with an object, is an important building block of early word learning for TD infants. This study investigated the development of word-I object associations by TD infants and infants and toddlers with Williams syndrome (WS), a rare genetic disorder associated with delayed language and cognitive…

Typically developing (TD) infants adapt to the social world in part by shifting the focus of their processing resources to the relevant aspects of a visual scene. Any impairment in visual orienting may therefore constrain learning and development in domains such as language. However, although something is known about visual orienting in infants at…

Parents' reactions to toddlers' emotions were examined in relation to toddler shyness and gender in a sample of 103 parents (99 mothers, 4 fathers) of 2 year olds. Toddlers were grouped as shy (N = 52; 23 boys) or non-shy (N = 51; 25 boys) using a temperament survey administered by phone, then parents completed questionnaires regarding their…

Meta-analyses of head circumference in autistic individuals exist; however, simple meta-analytic approaches are limited. Consequently, we gathered head circumference raw data of autistic (N = 2381) and typically developing participants (N = 994) by re-analysing the data from previously published studies together. The present study found no mean…

It has been suggested that due to functional similarity, sortal object individuation might be a primordial form of psychological essentialism. For example, the relative independence of identity judgment from perceived surface features is a characteristic of essentialist reasoning. Also, infants engaging in sortal object individuation pay more…

This study estimates the effect of physical punishment on the cognitive development of 1,167 low-income Colombian children (M[subscript age] = 17.8 months old) using 3 analytic strategies: lagged-dependent variables, a difference-in-differences-like approach (DD), and a novel strategy combining matching with a DD-like approach. Across approaches,…
