- Animal studies of attachment
- Imprinting
- Innate readiness to develop a strong bond with the mother which takes place rapidly. Has to happen in critical period, or won't at all.
- Study: Lorenz. Split gosling eggs into two groups. G1 left with natural mother. G2 placed in incubator. G2 saw Lorenz when born, attached to him. G1 saw natural mother, attached to her.
- Process irreversible, early imprinting has effects on later mate preferences
- Has to happen within critical period or wont at all.
- Harlow
- Two wire mothers. One covered in cloth, one with milk bottle. All 8 monkeys spent most time with cloth mother, and only went to wired for food. Comfort over food.
- More than 6 months with wire mother: developed abnormally, froze/fled from other monkeys, didn't cradle young, sexually abnormal
- Time spent with monkeys before 3 months old enabled recovery
- Evaluation
- S: Research support- Guiton 1966, leghorn chicks.
- W: Guiton reversed effects of imprinting, not very different from any other kind of learning, heads were different- monkeys may have preferred type of head to cloth, difficult to generalise to humans, ethical issues- study had long lasting negative effects on monkeys
- Imprinting
