Bastien, Kevin; Muckle, Gina; Ayotte, Pierre; Courtemanche, Yohann; Dodge, Neil C.; Jacobson, Joseph L.; Jacobson, Sandra W.; Saint-Amour, Dave – New Directions for Child and Adolescent Development, 2022
Inuit communities in Northern Quebec (Canada) are exposed to environmental contaminants, particularly to mercury, lead and polychlorinated biphenyls (PCBs). Previous studies reported adverse associations between these neurotoxicants and memory performance. Here we aimed to determine the associations of pre- and postnatal exposures to mercury, lead…

Bullens, Jessie; Igloi, Kinga; Berthoz, Alain; Postma, Albert; Rondi-Reig, Laure – Journal of Experimental Child Psychology, 2010
Navigation in a complex environment can rely on the use of different spatial strategies. We have focused on the employment of "allocentric" (i.e., encoding interrelationships among environmental cues, movements, and the location of the goal) and "sequential egocentric" (i.e., sequences of body turns associated with specific choice points)…

Balcomb, Frances; Newcombe, Nora S.; Ferrara, Katrina – Journal of Cognition and Development, 2011
The relationship between emergent spatial understanding in different cognitive domains, including navigation and language, has rarely been studied using methods that allow for the examination of individual differences. In this study the authors explored emergent place learning and its relationship to early spatial language, namely prepositions, in…

Nardini, Marko; Atkinson, Janette; Braddick, Oliver; Burgess, Neil – Developmental Science, 2008
Williams syndrome (WS) is a genetic disorder associated with severe visuocognitive impairment. Individuals with WS also report difficulties with everyday wayfinding. To study the development of body-, environment-, and object-based spatial frames of reference in WS, we tested 45 children and adults with WS on a search task in which the participant…

Cornell, Edward H.; And Others – Developmental Psychology, 1989
Examined the ability of 144 children of 6 and 12 years to respond to instructions to use environmental landmarks when leading the way. Children who were told they would lead the way did not prepare more adequately than children who were not told. Children did benefit from instructions to attend to environmental features. (RJC)

Nardini, Marko; Burgess, Neil; Breckenridge, Kate; Atkinson, Janette – Cognition, 2006
We studied the development of spatial frames of reference in children aged 3-6 years, who retrieved hidden toys from an array of identical containers bordered by landmarks under four conditions. By moving the child and/or the array between presentation and test, we varied the consistency of the hidden toy with (1) the body, and (2) the testing…
