What are the advantages of animal studies?
Psychologist are interested in this because attachment-like behaviour is common to a range of species and so animal studies can help us understand attachment in humans

ethics and extrapolation

one half was left to hatch with the mother (control group)
the other half were hatched in an incubator, the first moving thing they saw was Lorenz - experimental group
Results: Those hatchlings with the mother followed their mother goose everywhere, whereas the second group followed Lorenz
