AI Article Synopsis
- The study examined how 6-month-old infants mentally rotate objects using a violation-of-expectation approach.
- Forty infants watched an object being hidden and later revealed either as the original or the mirror image, with results indicating that those who explored the object beforehand paid more attention to the impossible mirror image.
- The findings suggest that hands-on experience enhances infants' cognitive skills, particularly in understanding object orientation.
Article Abstract
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 to manually explore the object prior to testing, the other half was only allowed to observe the object. Results showed that infants with prior hands-on experience looked significantly longer at the mirror image, while infants with observational experience did not discriminate between test events. These findings demonstrate that 6-month-olds' mental rotations benefit from manual exploration, highlighting the importance of motor experience for cognitive performance.
