Purpose: In this study, the authors investigated the hypothesis that the perceived tight temporal synchrony of speech and gesture is evidence of an integrated spoken language and manual gesture communication system. It was hypothesized that experimental manipulations of the spoken response would affect the timing of deictic gestures. Method: The…

Messinger, Daniel; Young, Gregory S.; Ozonoff, Sally; Dobkins, Karen; Carter, Alice; Zwaigenbaum, Lonnie; Landa, Rebecca J.; Charman, Tony; Stone, Wendy L.; Constantino, John N.; Hutman, Ted; Carver, Leslie J.; Bryson, Susan; Iverson, Jana M.; Strauss, Mark S.; Rogers, Sally J.; Sigman, Marian – Journal of the American Academy of Child & Adolescent Psychiatry, 2013
Objective: First-degree relatives of persons with an autism spectrum disorder (ASD) are at increased risk for ASD-related characteristics. As little is known about the early expression of these characteristics, this study characterizes the non-ASD outcomes of 3-year-old high-risk (HR) siblings of children with ASD. Method: Two groups of children…

How To Get to the Cafeteria: Gesture and Speech in Blind and Sighted Children's Spatial Descriptions.
Peer reviewed Peer reviewed
Iverson, Jana M. – Developmental Psychology, 1999
Evaluated gesture and speech in congenitally blind and sighted 9- to 17-year olds to assess hypothesized variations in representations of spatial tasks. Found that a majority of blind children gestured only in the small-scale path-description task. Absence of gesture among blind participants was related to "segmenting strategy" in speech rarely…

Infant Vocal-Motor Coordination: Precursor to the Gesture-Speech System?
Peer reviewed Peer reviewed
Direct linkDirect link
Iverson, Jana M.; Fagan, Mary K. – Child Development, 2004
This study was designed to provide a general picture of infant vocal-motor coordination and test predictions generated by Iverson and Thelen's (1999) model of the development of the gesture-speech system. Forty-seven 6- to 9-month-old infants were videotaped with a primary caregiver during rattle and toy play. Results indicated an age-related…

Iverson, Jana M.; Longobardi, Emiddia; Caselli, M. Cristina – International Journal of Language & Communication Disorders, 2003
Background: Previous research has emphasized the importance of gesture in early communicative development. These studies have reported that gestures are used frequently during the first two years of life and may play a transitional role in the language acquisition process. Although there are now numerous descriptions of the relationship between…
