Stimulus Generalization of Imprinting
Dianne A. Cofoid, Werner K. Honig · Science · 1961
Chicks were imprinted with a bluish object, then tested with different spectral values ranging to yellow-green. A systematic decrement in following was related to the stimulus series, although there was considerable generalization to all test values, which increased during testing. These data lead us to question the "irreversibility" of imprinting.
