Testosterone-injected and control male chicks were tested either for 3 min a day on consecutive days in an open field containing a bell which was sounded for the first 5 s, or for 3 min in a plain open field followed by a bell sounded from outside the field. In the 1st situation, hormone-injected chicks showed more freezing and immobility, but less active escape and avoidance responses. In the 2nd situation, testosterone-treated and control chicks did not show these differences. It was suggested that the occurrence of a localized aversive stimulus (the bell) in the center of the open field had resulted in different types of fear behavior in the 2 types of chick because the hormone injected group attended more to the localized stimulus.
