In spoken languages, children acquire locative terms in a cross-linguistically stable order. Terms similar in meaning to in and on emerge earlier than those similar to "front" and "behind," followed by "left" and "right." This order has been attributed to the complexity of the relations expressed by…

Williams syndrome (WS) is a rare genetic syndrome. As with all rare syndromes, obtaining adequately powered sample sizes is a challenge. Here we present legacy data from seven UK labs, enabling the characterisation of cross-sectional and longitudinal developmental trajectories of verbal and non-verbal development in the largest sample of…

Purpose: The purpose of this study was to investigate the relationship of the grunt vocalizations to cognitive and expressive language status in children with disabilities. Children with typical development produce communicative grunts at the onset of referential word production and comprehension at 14-16 months of age and continue to use this…

Adults' and 8-year-old children's perception of emotional faces is disrupted when faces are presented in the context of incongruent body postures (e.g., when a sad face is displayed on a fearful body) if the two emotions are highly similar (e.g., sad/fear) but not if they are highly dissimilar (e.g., sad/happy). The current research investigated…

In recent years, the intersection of cognitive psychology, developmental psychology, and neuroscience with regard to deaf individuals has received increasing attention from a variety of academic and educational audiences. Both research and pedagogy have addressed questions about whether deaf children learn in the same ways that hearing children…

Speakers convey meaning not only through words, but also through gestures. Although children are exposed to co-speech gestures from birth, we do not know how the developing brain comes to connect meaning conveyed in gesture with speech. We used functional magnetic resonance imaging (fMRI) to address this question and scanned 8- to 11-year-old…

Using 20 levels of intensity, we measured children's thresholds to discriminate the six basic emotional expressions from neutral and their misidentification rates. Combined with the results of a previous study using the same method ("Journal of Experimental Child Psychology, 102" (2009) 503-521), the results indicate that by 5 years of age,…

The primary purpose of this study was to examine the effect of the intensity of emotion expression on children's developing ability to label emotion during a dynamic presentation of five facial expressions (anger, disgust, fear, happiness, and sadness). A computerized task (AFFECT--animated full facial expression comprehension test) was used to…

Susan Goldin-Meadow's "Hearing Gestures: How Our Hands Help Us to Think" synthesizes findings from various domains to demonstrate that gestures convey meaning and comprise a critical and fundamental form of communication. She also argues convincingly for the cognitive utility of gesture for the gesturer. Goldin-Meadow presents an airtight case…

To examine the neurobiological consequences of early institutionalization, the authors recorded event-related potentials (ERPs) from 3 groups of Romanian children--currently institutionalized, previously institutionalized but randomly assigned to foster care, and family-reared children--in response to pictures of happy, angry, fearful, and sad…

In this study, self-regulation was investigated in 7- to 10-year-old children using three different measures: (1) parent and child report questionnaires measuring temperamental effortful control, (2) a conflict task assessing efficiency of executive attention, and (3) the mistaken gift paradigm assessing social smiling in response to an…

This research extends the range of domains within which children's gestures are found to play an important role in learning. The study involves children learning about balance, and the authors locate children's gestures within a relevant model of cognitive development--the representational redescription model (A. Karmiloff-Smith, 1992). The speech…

When a behavior disappears and then resurfaces, developmental psychologists typically look more closely at the behavior to figure out what is different before and after--that is, they increase the grain with an eye toward discovering how the system that generates that behavior has changed. But what ought to count as a U-shaped phenomenon? How…

Examined the development of communicative competence in deaf children and its interactions with use of communicative gestures and/or words. Data indicated (1) the use of communicative gestures increased with age while speech remained constant; and (2) the number of gestures used correlated with communicative accuracy. Difficulty level influenced…

Studies of children's deceptive behavior have scientific merit and can be carried out in an ethically defensible manner. Many arguments against studies requiring children to deceive others in an experimental context are relatively easy to refute. It is true, though, that the debriefing phase of deception studies presents ethical problems,…
