Inability of Five-Month-Old Infants To Retrieve a Contiguous Object: A Failure of Conceptual Understanding or of Control of Action?
Peer reviewed Peer reviewed
Diamond, Adele; Lee, Eun Young – Child Development, 2000
Examined infants' ability to retrieve an object from atop a slightly larger object. Found that even 5-month-olds could retrieve objects close in size and fully contiguous with their bases when demands on reaching skill were reduced. Proposed that when they fail this task, it is because they lack the skill to reach the top object without…

How Infants Use Vision for Grasping Objects.
Peer reviewed Peer reviewed
McCarty, Michael E.; Clifton, Rachel K.; Ashmead, Daniel H.; Lee, Philip; Goubet, Nathalie – Child Development, 2001
Three experiments examined vision's role in infants' grasping of horizontally and vertically oriented rods. Found that infants differentially oriented their hand regardless of lighting and similar to control conditions where they could see rod and hand throughout reach. Findings suggest that infants may use current sight of object's orientation or…

Visual-Proprioceptive Intermodal Perception Using Point Light Displays.
Peer reviewed Peer reviewed
Schmuckler, Mark A.; Fairhall, Jennifer L. – Child Development, 2001
Three experiments explored 5- and 7-month-olds' intermodal coordination of proprioceptive information produced by leg movements and visual movement information specifying these same motions. Results suggested that coordination of visual and proprioceptive inputs is constrained by infants' information processing of the displays and have…
