Touching up mental rotation : Effects of manual experience on 6-month-old infants’ mental object rotation

Möhring, Wenke ; Frick, Andrea

In: Child Development, 2013, vol. 84, no. 5, p. 1554-1565

In this study, 6-month-olds’ ability to mentally rotate objects was investigated using the violation-of-expectation paradigm. Forty infants watched an asymmetric object being moved straight down behind an occluder. When the occluder was lowered, it revealed the original object (possible) or its mirror image (impossible) in one of five orientations. Whereas half of the infants were allowed...

Mental object rotation and motor development in 8- and 10-month-old infants

The present study investigated whether older infants, at 8 and 10 months of age, succeed in this task after observational experience only, and...
