An experiment with 72 three-year-olds investigated whether encoding events while seeing iconic gestures boosts children's memory representation of these events. The events, shown in videos of actors moving in an unusual manner, were presented with either iconic gestures depicting how the actors performed these actions, interactive gestures, or no…

This study took a novel approach to understanding the role of language in spatial development by combining approaches from spatial language and gesture research. It analyzed forty-three 4.5- to 6-year-old's speech and gesture production during explanations of reasoning behind performance on Spatial Analogies and Children's Mental Transformation…

Studies have suggested that language and executive function (EF) are strongly associated. Indeed, the two are difficult to separate, and it is particularly difficult to determine whether one skill is more dependent on the other. Deafness provides a unique opportunity to disentangle these skills because in this case, language difficulties have a…

In humans, effortful cognitive processing frequently takes place during social interaction, with eye contact being an important component. This study shows that the effect of eye contact on memory for nonsocial information is different in children with typical development than in children with autism, a disorder of social communication. Direct…

Emotion recognition was investigated in typically developing individuals and individuals with autism. Experiment 1 tested children (5-7 years, n = 37) with brief video displays of facial expressions that varied in subtlety. Children with autism performed worse than the control children. In Experiment 2, 3 age groups (8-12 years, n = 49; 13-17…

This study provides experimental evidence for automatic, relationship-specific social information processing in 13-year-old adolescents. Photographs of participants' liked, disliked, and unknown peers were used as primes in an affective priming task with happy and angry facial expression probes and in a hypothetical vignette task. For the…

Given that gestures may provide access to transitions in cognitive development, preschoolers' performance on standard tasks was compared with their performance on a new gesture false belief task. Experiment 1 confirmed that children (N45, M age54 months) responded consistently on two gesture tasks and that there is dramatic improvement on both the…

Proposes that young children employ two ordered, nonverbal classification strategies to interpret vague referential instructions: first, they rely on context; then, if the first strategy fails, they guess. If the guess goes uncorrected, they conclude that it was correct. Two studies provide evidence supporting children's use of the hypothesized…

Three studies examined theory-of-mind concepts among children ages 6-13 years with deafness or autism, and 4-year-olds with normal development. Findings indicated that while the children with deafness or autism scored significantly lower on standard tests of false belief understanding, they scored higher on even the most challenging drawing-based…
