Lorenz C. 1952) Imprinting
Procedure
Konrad Lorenz randomly divided a
large clutch
of goose eggs :
'
one hatched with the mother
half were
goose in the natural environment
hatched moving
'
the other in an incubator where the
first object they saw was Lorenz .
Mixed all
goslings to see whom
they would
follow
Lorenz also observed birds and their later courtship behaviour
Findings and conclusions .
Incubator mother
group followed Lorenz , control
group followed
.
Lorenz
identified critical peroia which
imprinting needs to take place hours

If imprinting didn't occur that ,
chicks didn't attach themselves to the mother
figure .
Sexual
imprinting also occurs
whereby the birds acquire a template of the desirable characteristics in a mate .
