Systems in Development: Motor Skill Acquisition Facilitates Three-Dimensional Object Completion
Peer reviewed Peer reviewed
Direct linkDirect link
Soska, Kasey C.; Adolph, Karen E.; Johnson, Scott P. – Developmental Psychology, 2010
How do infants learn to perceive the backs of objects that they see only from a limited viewpoint? Infants' 3-dimensional object completion abilities emerge in conjunction with developing motor skills--independent sitting and visual-manual exploration. Infants at 4.5 to 7.5 months of age (n = 28) were habituated to a limited-view object and tested…

Infants' Sensitivity to Optical Flow for Controlling Posture.
Peer reviewed Peer reviewed
Bertenthal, Bennett I.; Bai, Dina L. – Developmental Psychology, 1989
Results of a study of 68 infants of 5-14 months revealed that partial optical flow is generally sufficient for inducing postural compensations, but the amplitude and consistency of the response depend on the location of the flow in the optic array. (RJC)

Effect of Self-Produced Locomotion on Infant Postural Compensation to Optic Flow.
Peer reviewed Peer reviewed
Higgins, Carol I.; And Others – Developmental Psychology, 1996
Compared the postural responsiveness of seven-, eight-, and nine-month-old infants. Results indicated greater use of optic flow for postural control after a self-produced locomotor experience. Infants with endogenous (creeping) or artificial (walker) self-produced locomotor experience responded to portions of the optic flow field, whereas…

Age Differences in the Relationship between Visual Movement Imagery and Performance on Kinesthetic Acuity Tests.
Peer reviewed Peer reviewed
Livesey, David J. – Developmental Psychology, 2002
Investigated the relationship between Vividness of Movement Imagery Questionnaire scores and kinesthetic acuity--the sense of body position and movement--among 10- and 14-year-olds. Found that in the older group, those with high levels of visual movement imagery performed better on measures of kinesthetic acuity; no such effect was found for…
