Abstract

MODIFIABILITY OF THE CRITICAL PERIOD FOR THE DEVELOPMENT OF MATERNAL BEHAVIOR IN SHEEP AND GOATS 1) by LEONARD HERS HER, JULIUS B. RICHMOND, and A.

Critical periods probably vary in duration for different kinds of behavior and for different types of organisms, from the entire juvenile or adult stage to very brief but crucial periods of time.
