• Lorenz research:

  • studied imprinting on geese
  • took some eggs from a goose and kept them incubated so the first thing they saw was lorenz
  • kept the other eggs with the mother
• Lorenz's findings:

  • The incubator group followed lorenz everywhere and the control group followed their mother everywhere
  • this is imprinting and there is a critical period where this takes place
• Lorenz also investigated the relationship between imprinting and mate preference.

  He observed a peacock try and mate with a tortoise as it was raised in a reptile household.
• Harlows monkeys:

  • They were kept in cages, the monkey made out of wire had the bottle attached to it, and there was another monkey with cloth
  • the monkeys preferred the cloth monkey showing that feeding is not important when forming attachments
