Perception of invariants by five-month-old infants: Differentiation of two types of motion

Academic Article

Abstract

  • Habituated 5-mo-old infants to 3 types of visually presented rigid motion. Duration of fixation was the dependent measure. After reaching a criterion of habituation, a 4th rigid motion (not habituated) and a deformation were presented. Dishabituation was significantly greater to the deformation than to the 4th rigid motion. Comparison with a no-change control condition showed a significant difference for deformation when it followed the 4th rigid motion. It is inferred that the infants detected the invariant property of rigidity and differentiated it from the deformation.
