Attachment - Animal studies Flashcards
Outline Lorenz’s study into attachment(6marks)
Aim: test effects of imprinting
Procedure: clutch of gosling eggs divided in 2, one group left with himtill they hatch and one with mother. marked both - easy to distinguish - when hatched one group imprinted on Lorenz and one on mother.
Findings: Noticed several long lasting effects of reciprocity which are irreversible. It also effected mating preference as they tried to mate w/ animal imprinted to
Outline Harlow’s study into attachment? (6-8marks)
AO1: Harlow created 2 wire monkeys with same head, one had cloth wrapped around it. 8 infant rhesus monkeys were raised in isolation cages for 3 months. in 4/8 cages wire monkey held feeding bottle and in others cloth monkey did. Results: No matter about food provision, he found monkeys from both groups spent most time w/ cloth monkey and if it didnt have food they only went over to the one with food to feed. He also created frightening situation w/ a robot and they always went to cloth mum for comfort. Continued: He continued to study them and they developed socially and sexually abnormally . He found a critical period - if they spent some time w/ other monkeys they would recover but not fully.
Give 3 evaluation points for Harlows study into attachment
EVALUTATION:
1) Ethical issues - immoral and ruined monkeys future lives
2) Not generalisable (monkeys dont act same)
3) FACE of surrogate mother is the same so it could be that.
Give an evaluation point for Lorenz
EVALUATION: - Guiton did study where he exposed chicks to yellow glove feeding them and they became imprinted to the gloves. (they also tried to mate w/ gloves)
