Peer reviewed Peer reviewed
Direct linkDirect link
Andersson, Ulf; Lyxell, Bjorn – Journal of Experimental Child Psychology, 2007
This study examined whether children with mathematical difficulties (MDs) or comorbid mathematical and reading difficulties have a working memory deficit and whether the hypothesized working memory deficit includes the whole working memory system or only specific components. In the study, 31 10-year-olds with MDs and 37 10-year-olds with both…

Age Differences in Visual Reaction Time of "Brain Damaged" and Normal Children under Irregular Preparatory Interval Conditions
Peer reviewed Peer reviewed
Czudner, G.; Rourke, B. P. – Journal of Experimental Child Psychology, 1972
Results support the contention that with advancing years brain-damaged children may adapt to and/or recover from the deficit(s) involved in the inability to develop and maintain a readiness to respond. (Author/MB)

Rourke, B. P.; Czudner, G. – Journal of Experimental Child Psychology, 1972
Results of these studies support the contention that with advancing years brain-damaged children of the type used in the present study may adapt to and/or recover from the dificit(s) involved in the inability to develop and maintain a state of readiness to respond. (Authors)

A Longitudinal Study of the Development of Shifts of Gaze to a Peripheral Stimulus in Preterm Infants with Transient Periventricular Echogenicity.
Peer reviewed Peer reviewed
Butcher, Phillipa R.; Kalverboer, Alex F.; Geuze, Reint H.; Stremmelaar, Elizabeth F. – Journal of Experimental Child Psychology, 2002
Investigated shifts of gaze to peripheral targets in full-term and very preterm infants with transient periventricular echogenicity, a type of short-term brain damage, between 6-26 weeks old. Found that differences between full- and preterm infants was small, but after 16 weeks, there were subtle differences between them as preterms took longer to…
