Babies' Attachment Development & Animal Studies in Psychology
Babies' attachment development is studied through ethology, imprinting, and critical periods. Animal studies by Lorenz, Harlow, and others explore the impact of isolation and imprinting on behavior. Practical applications include orphaned goslings, sexual imprinting, and therapy for social deprivation. Listen to related radio shows for further insights.

How do babies develop attachments? Lorenz Key terms: Ethology Imprinting Critical period
Real Life Application Orphaned goslings and micro-light aircraft Whooping cranes and micro-light aircraft Sheep farmers mother sheep Olfactory imprinting
Sexual Imprinting Lorenz (1952) case study a peacock raised in a reptile house had imprinted on a giant tortoises. As an adult this Peacock would attempt to mate display courtship rituals to giant tortoises. They had undergone sexual imprinting.
Harlow Variations Isolation studies newborn monkeys kept in isolation for 3, 6, 12 or 24 months. Monkey were psychologically disturbed. Fearful of other monkeys attacked them and harmed themselves. Rape rack female forcibly mated. When they became parents they abused their babies chewed off their feet, crushed their skulls.
Slucklin (1966) Duckling Sensitive rather than critical period. Imprinted a duckling who was isolated for 5 days after hatching.
Harlow & Suomi (1972) Therapy Isolated 4 newborn male monkeys for 6 months, Placed each with a normal monkey for two hours three times and week and increased contact. 12 months + their behaviour was normal. Total isolation is reversible.
