Lorenz supports Bowlby's Monotropic Theory, as the attachment process of imprinting is an innate process which has a critical period.
Animal studies have been conducted to study attachment due to ethical issues in studying human attachment.
Imprinting is the process by which some birds instinctively bond with the first moving object they see within hours of hatching.
Imprinting occurs within a critical period, and if an offspring is not exposed to a moving object during this time, they will fail to form an attachment.
Animals imprint a mental image of the first moving object they see after birth, and attachment is an instinctive process.
Geese that imprinted on Lorenz followed him throughout their early life and into adulthood.
Lorenz's research with goslings influenced John Bowlby and Mary Ainsworth in their studies on human attachments.
Hess further developed Lorenz's theory of imprinting by showing the timing and strength of the response in goslings.
Criticisms of Lorenz's research include the limited opportunity for goslings to choose their imprinted parent and the potential reversibility of imprinting with further socialisation.
Guiton (1966) studied leghorn chicks, and offers support for Lorenz's theory of imprinting.
Guiton (1966) showed that imprinting can be reversed through socialisation with their own species.
Animal studies of attachment may not be directly generalisable to humans due to differences in conscious decision-making and emotional bonding. Further research is needed.
Imprinting is the instinctive drive of an animal to form an attachment with the first moving thing it sees soon after birth.
One piece of research that supports the idea of imprinting in animals is the studies conducted by Lorenz (1930s onwards) on birds.
There are limitations of using animal studies to understand human attachment include the differences in brain development, cognitive abilities, and social complexity between humans and non-human animals.
Regolin & Vallortigara (1995) support the idea of imprinting and suggest animals are born with an instinct to attach.
Natural experiments like Lorenz (1952) have high ecological validity.
