Synchronous Change and Perception of Object Unity: Evidence from Adults and Infants.

This study compared role of motion in adults' and infants' perception of object unity. Findings favored ecologically-oriented accounts of object perception. Motion was a determinant of object unity for infants. Alignment and common motion contributed to adults' object-unity perception; synchronous color changes did not. Infants detected synchronous changes, but failed to use them as information for object unity. (Author/KB)
