Recovery from experimentally induced problem solving deficits in neo natal peking ducklings anas platyrhynchos as a function of environmental stimulation


, : Recovery from experimentally induced problem solving deficits in neo natal peking ducklings anas platyrhynchos as a function of environmental stimulation. Developmental Psychobiology 14(1): 59-66

Neonatal Peking ducklings were reared in 3 different environments containing varied light and sound stimulation. One group was exposed to the stimulative environment only during the last 3 prenatal days, 1 group was placed in the stimulative environment at the time of hatching, and the 3rd group was exposed to the stimulative environment both pre- and postnatally. No differences in performance in a detour learning task were noted between controls and experimentals from the first 2 groups (prenatal stimulation only and postnatal stimulation only); the group receiving both pre- and postnatal stimulation solved the detour task significantly faster than their controls. This learning improvement as a function of the stimulative environment represents a partial recovery from the deficit produced as a result of the experimental paradigm in which the shell covering the air space was replaced with clear plastic wrap, a procedure which reduces O2 consumption and leads to learning retardation.
