Analyzed in detail the conditions eliciting approach behavior to the imprinting stimulus in White Leghorn, New Hampshire, and hybrid White Leghorn-New Hampshire chicks. It was found that the approach response to a relatively weak imprinting stimulus could arise by 2 different mechanisms. Some Ss approached the stimulus object within a few min.; others needed a considerably longer stimulation, essentially a conditioning, to elicit the approach response. The 2 mechanisms, which were termed "prompt approach" and "conditioned approach," were distinguished on the basis of the different conditions required for eliciting them.
