outline the findings of Harlow's research of attachment in monkeys
- monkeys preferred the cloth mother over the wire mother, some staying there for up to 22 hours a day and clinging onto the cloth mother while feeding from the wire mother
- monkeys with ONLY the wire mother had diarrhoea which was a sign of stress
- when frightened by the machine, monkeys would cling to the cloth mother
- in the larger cage, monkeys raised by the cloth more were more explorative, using the mother as a 'safe base' to explore from
- this showed that the availability for comfort in rhesus monkeys was more important in forming attachments than the availability of food, and this comfort was associated with lower levels of stress
