Experience with Pointing Gestures Facilitates Infant Vocabulary Growth through Enhancement of Sensorimotor Brain Activity
Peer reviewed Peer reviewed
Direct linkDirect link
Salo, Virginia C.; Debnath, Ranjan; Rowe, Meredith L.; Fox, Nathan A. – Developmental Psychology, 2023
Exposure to communicative gestures, through their parents' use of gestures, is associated with infants' language development. However, the mechanisms supporting this link are not fully understood. In adults, sensorimotor brain activity occurs while processing communicative stimuli, including both spoken language and gestures. Using…

Learning about Tools in Infancy
Peer reviewed Peer reviewed

Barrett, Tracy M.; Davis, Evan F.; Needham, Amy – Developmental Psychology, 2007
These experiments explored the role of prior experience in 12- to 18-month-old infants' tool-directed actions. In Experiment 1, infants' use of a familiar tool (spoon) to accomplish a novel task (turning on lights inside a box) was examined. Infants tended to grasp the spoon by its handle even when doing so made solving the task impossible (the…

Imitation in Newborn Infants: Exploring the Range of Gestures Imitated and the Underlying Mechanisms.
Peer reviewed Peer reviewed
Meltzoff, Andrew N.; Moore, M. Keith – Developmental Psychology, 1989
Evaluated psychological mechanisms underlying imitation of facial actions in 40 newborn infants. Results showed imitation of head movement and a tongue-protrusion gesture. Subjects imitated from memory after displays had stopped. (RJC)

Motor Schema Formation in Children.
Peer reviewed Peer reviewed
Kelso, J. A. Scott; Norman, Patrice E. – Developmental Psychology, 1978
Investigates the effects of variable-practice versus constant-practice on the learning of novel motor schemata in 36 children ranging in age from two years one month to four years. (Author/SS)

Learning to Reach: A Mathematical Model.
Peer reviewed Peer reviewed
Berthier, Neil E. – Developmental Psychology, 1996
Presents a mathematical model of the development of reaching behavior in infants, along with the results of two experiments that showed that infant movements could be decomposed into the underlying submovements using a principled method; and the angular error in infant reaches matches the form and magnitude of error assumed by the model.

Infants' Predictive Reaching for Moving Objects in the Dark.
Peer reviewed Peer reviewed
Robin, Daniel J.; And Others – Developmental Psychology, 1996
Thirteen infants were presented with a moving object under two lighting conditions to investigate the role of vision in early reaching. Infants were tested twice, at 5 and 7.5 months of age. The results suggest that proprioceptive feedback and sight of the target allowed for successful reaching with limited visual information, even in relatively…

Infants Use Handrails as Tools in a Locomotor Task.
Peer reviewed Peer reviewed
Berger, Sarah E.; Adolph, Karen E. – Developmental Psychology, 2003
Two experiments examined problem solving in 16-month-olds' adaptive locomotion (crossing bridges of varying width with/without handrail). Findings indicated that toddlers attempted wide bridges more than narrow ones. Attempts on narrow bridges depended on handrail presence. Toddlers had longer latencies, examined bridge/handrail more closely, and…
