Infants' Use of Material Properties to Guide Their Actions with Differently Weighted Objects
Paulus, Markus; Hauf, Petra
Infant and Child Development, v20 n4 p423-436 Jul-Aug 2011
Two studies with 9-, 11- and 13-month-old infants were conducted to investigate infants' ability to use an object's material properties to guide their object-directed actions. In study 1, 9- and 11-month-old infants played in an exploration phase with two objects made of different materials, one very heavy and the other one light and playable. Subsequently, when given the choice between both objects in a preferential reaching task, only the 11-month-olds' used the object's material information to remember and choose the lighter object. In study 2, 11- and 13-month-old infants underwent the same exploration phase. In the test phase, novel objects made of the same materials were offered. The 13- but not the 11-month-olds chose the objects made from the same material as the lighter object in the exploration phase. Additionally, infants' performances in the reaching task were positively correlated with their exploratory behaviour during the exploration phase. Altogether, the studies show a developmental progression in the use of an object's material information to guide infants' action. The results are discussed in respect to infants' perception of object properties and their implications for the development of physical knowledge. (Contains 2 figures, 1 table, and 1 note.)
