Peer reviewed Peer reviewed

Brady, Danielle I.; Saklofske, Donald H.; Schwean, Vicki L.; Montgomery, Janine M.; Thorne, Keoma J.; McCrimmon, Adam W. – Focus on Autism and Other Developmental Disabilities, 2017
Researchers have proposed that autism spectrum disorder (ASD) is characterized, at least in part, by executive function (EF) difficulties associated with the integrity of the frontal lobe. Given the paucity of research regarding EFs in young adults with high functioning ASD (HF-ASD), this research involves an examination of various indices of EF…

Visual Size Perception and Haptic Calibration during Development
Peer reviewed Peer reviewed

Gori, Monica; Giuliana, Luana; Sandini, Giulio; Burr, David – Developmental Science, 2012
It is still unclear how the visual system perceives accurately the size of objects at different distances. One suggestion, dating back to Berkeley's famous essay, is that vision is calibrated by touch. If so, we may expect different mechanisms involved for near, reachable distances and far, unreachable distances. To study how the haptic system…

Objects, Numbers, Fingers, Space: Clustering of Ventral and Dorsal Functions in Young Children and Adults
Peer reviewed Peer reviewed
Direct linkDirect link
Chinello, Alessandro; Cattani, Veronica; Bonfiglioli, Claudia; Dehaene, Stanislas; Piazza, Manuela – Developmental Science, 2013
In the primate brain, sensory information is processed along two partially segregated cortical streams: the ventral stream, mainly coding for objects' shape and identity, and the dorsal stream, mainly coding for objects' quantitative information (including size, number, and spatial position). Neurophysiological measures indicate that such…

Out of Sight Is Not out of Mind: Developmental Changes in Infants' Understanding of Visual Perception during the Second Year
Peer reviewed Peer reviewed
Direct linkDirect link
Poulin-Dubois, Diane; Sodian, Beate; Metz, Ulrike; Tilden, Joanne; Schoeppner, Barbara – Journal of Cognition and Development, 2007
Three experiments investigated 14-, 18-, and 24- month-old infants' understanding of visual perception. Infants viewed films in which a protagonist was either able to view the location of a hidden object (Visual Access condition) or was blindfolded when the object location was revealed (No Visual Access condition). When requested to find the…

Developmental Differences in Judgments of Recency and Frequency: Quantitative or Qualitative?
Peer reviewed Peer reviewed
Direct linkDirect link
Chalmers, Kerry A.; Grogan, Melissa J. – Cognitive Development, 2006
The basis of young children's performance of judgments of recency and frequency was investigated using a modified version of Huppert and Piercy's [Huppert, F. A., & Piercy, M. (1978). The role of trace strength in recency and frequency judgements by amnesic and control subjects. Quarterly Journal of Experimental Psychology, 30, 347-354]…

Eye Movements and Visual Function in Infancy: The Problem of Interdependence.
Mitkin, A. – 1987
Reported are three series of experiments analyzing the development of the visual function of infants. The first experimental series was aimed at the investigation of infants' reaction to moving objects. The second experimental series dealt with the analysis of the development of binocular vision in infants. The goal of the third series was to…
