Animal studies

• Animal studies - Lorenz

  Goslings saw Lorenz when they hatched

  Newly-hatched chicks attach to the first moving object they see (imprinting)

  Sexual imprinting. adult birds r to mate with whatever species or object they imprint on
• Lorenz evaluation

  +research support, Regolin observed chicks imprint on moving shapes

  -generalisability to humans, attachment systems in birds are less complex and not two-way
• Animal studies - Harlow

  Baby rhesus monkeys given cloth or wire mother with feeding bottle attached

  Monkeys clung to cloth surrogate rather than wire one

  Maternally deprived monkeys grew up socially dysfunctional

  After 90 days attachments wouldn’t form - ’critical period’
• Harlow evaluation

  +real world value, helps professionals to promote bonding and applied to zoos and breeding programmes

  -generalisability to humans, although more similar than birds monkey’s are not as complex as humans
