Document Summary

Behavior not dependent on postnatal experience with call: check ppt, experimental design and results. Test behavior (response to duck call) after hatching: devocal-isolated -----> no preference, devocal-isolated-exposed to chicken ------> chicken preference, vocal-isolated-exposed to chicken -------> no preference, vocal-with sibs-exposed to chicken call ------> mallard preference. Species recognition upon prenatal experience with own and sibling"s vocalizations: conclusions, normally occurring sensory stimulation was critical for development of a species-typical behavior. Behavior that seemed instinctive and innate turned out to be problematic, with multiple determinants both maturational and experiential. Structure only fully realizes itself through function experience= patterns of stimulation: sources of stimulation: life before birth, uterine life has significant stimulation, babies are not born with no experience/no learning. Pregnant rats sent into space to test the effects of pre and postnatal gravity: when back on earth, they did not right themselves when dropped into a tub while the earth-born rats were able to right themselves.
