Animal studies of attachment

• validty and lorenz study( eval.)

  high internal- set out what it planned to do.

  high external-applies to all geese but could be argued with human appplication.
• Reliability and lorenz study(eval.)

  high reliability

  replicated several times by other experiments.
• What does imprinting suggest about attachment?

  it is innate and pre-programmed genetically.
• Whst is imprinting?

  process in which geese follow the first moving object they see during the critical period( 12-17 hours
• What did he do?

  collected a batch of eggs till they were to hatch

  1/2 of eggs placed under a goose mother, others with him for several hours.

  imitated mother quacking sounds when they hatched.
• What was Harlows aim?

  to study the mechanisms by which newborn rhesus monkeys bond to their mothers.
• Harlows study and ethical issues

  -experiments have been seen as unnecessarily cruel and unethical

  -limited value on deprivation of human infants
• Validity and harlows study

  not generalisable to humans- lacks ecological validit
• How is harlows study useful to human application and behaviour?

  helped social workers to understand risk factors inchild neglect and abuse such as a lack of comfort (and so intervene to prevent it).Using animals to study attachment can benefit children that are most at risk in society, can also have later economicimplications as those children are more likely to grow up to be productive members of society
• What were his findings?

  infant would only go to wire mother when hungry, and then return to cloth mother. frightening objects palced in the cage also meant the monkey took refuge with the cloth monkey.
• What was harlows procedure?

  studied 8 monkeys for 165 days who seperated from birth mother, placed into cages with 2 surrogate mothers. One made of wire that fed the baby, and one made of cloth for comfort
