A weakness of Lorenz's study?

-Criticism of the process -Guiton found that the chickens imprinting on the yellow gloves were reveresed. -After spending time with their own species, they could engage in normal sexual behaviour with other chickens. Suggests its more plastic and flexible mechanism than thought initially. -Suggests that imprinting is not differnt from other kinds of learning, rapid, done with litte conscious effort and reversible. Changes inital view about the permanence of imprinting.
