Visually controlled modes of behaviour of domestic chicks, reared singly for 24 hr. either in light or in darkness, were studied. Expt. I provided data concerning the chicks' approach responses, Expt. II tested chiefly the chicks' avoidance of moving objects and attendant vocalizations, and Expt. III investigated their pecking. It was found that dark‐reared animals were less apt to make ‘distress’ calls, tended to approach a moving object more readily, tended to show fewer avoidance responses, and pecked more than light‐reared animals. These findings provide a measure of confirmation of the ‘incongruity hypothesis of fear’, although certain deficiencies of this hypothesis are recognized.
