Animal studies of attachment Flashcards
What was the aim of Lorenzo’s study (1953)
To investigate the mechanisms of imprinting.
What was the procedure of Lorenzo’s study (1953)
Took a clutch of gosling eggs and divided them into two groups.
One group was left their natural mother while the other eggs were placed in an incubator.
When the incubator eggs hatched the first living (moving) thing they saw was Lorenzo and they started to follow him around.
To test the effect of imprinting Lorenzo marked the two groups to distinguish them and placed the together; they’d become on him.
Both Lorenzo and their natural mother were present.
What were the findings of Lorenzo’s study (1953)
The goslings divided themselves up into two groups; one group following their natural mother and the others following Lorenzo.
Lorenzo also discovers their is a specific amount of time in which imprinting can take place which is called the critical period.
Lorenzo also discovered that imprinting on humans doesn’t work for some humans.
what were the long lasting effects of Lorenzo’s research (1935)?
The imprinting process is irreversible and long lasting.
One strength of Lorenzo’s (1935) research
Guiton (1966) conducted research consisting of leghorn chicks imprinting on yellow gloves which supports Lorenzo’s findings.
One weakness of Lorenzo’s research (1935)
Research shows the opposite of Lorenzo’s research making it less replicable.
What was the aim of Harlow’s research (1959)?
To investigate
