Peer reviewedKaiser, Mary Kister; Proffitt, Dennis R. – Child Development, 1984
Examines whether kindergarteners, second-graders, fourth-graders, and adults can extract relative weight information from observing collisions and lifting events, and if they can judge whether or not collisions are momentum-conserving. Subjects saw either videotapes of events or sequences of static images; younger children appeared to be…
