A defining feature of ASD is atypical gaze behaviour, however, eye-tracking studies in 'real-world' settings are limited, and the possibility of improving gaze behaviour for ASD children is largely unexplored. This study investigated gaze behaviour of ASD and typically developing (TD) children in their classroom setting. Eye-tracking technology…

Neurofibromatosis Type 1 (NF1) is a common autosomal dominant single-gene disorder, in which the co-occurrence of autism spectrum disorder (ASD) has attracted considerable research interest recently with prevalence estimates of 21-40%. However, detailed characterization of the ASD behavioral phenotype in NF1 is still lacking. This study…

Eye gaze plays a pivotal role during communication. When interacting deceptively, it is commonly believed that the deceiver will break eye contact and look downward. We examined whether children's gaze behavior when lying is consistent with this belief. In our study, 7- to 15-year-olds and adults answered questions truthfully ("Truth" questions)…

Examines children's ability to use their knowledge to guide their behavior in a dimensional change, color-shaped card sort. Subjects were asked to sort cards according to different guidelines. Four experiments were carried out which show a disassociation between knowledge and its use. Findings indicate that knowing rules is sometimes insufficient…

Presents a study demonstrating that aid-giving by children is predicated by nonverbal displays of submission emitted by the child under attack, and that although the children observing the episodes respond to the displays, the aggressor ignores them. (JMF)

This experiment examined children's and undergraduates' verbal and nonverbal deceptive behavior, and the extent to which their truths and lies could be correctly classified by paying attention to these responses. Participants (N = 196) aged 5-6, 10-11, and 14-15, as well as university undergraduates, participated in an erasing the blackboard…

The purpose of this study was to investigate nonverbal facial, body, and paralanguage cues to deception in children. A sample of 31 Hispanic and Black second and third grade students were videotaped while playing a color identification that required six honest and six deceptive verbal responses to a randomized stimulus presentation. Frame-by-frame…

Body movements and facial expressions of males and females in a restaurant setting were examined, with the goal of providing differences in frequency as a function of age and sex. The subjects (N-197 males and N=131 females) were seated in three Seattle fast food restaurants and were selected on a semi-random basis and then observed for three…
