Janssen, Rianne; De Boeck, Paul; Viaene, Mieke; Vallaeys, Lies
Journal of Experimental Child Psychology, v74 n3 p261-81 Nov 1999
Speeded performance on simple mental addition problems of 6- and 7-year-olds with and without mild mental retardation was modeled from a person perspective and an item perspective, both inferred from Siegler's work. Models from item response theory were used to test hypotheses. Found that all children follow same developmental path in acquiring automated performance on simple mental addition problems. (EV)
