In female chicks, testosterone increases both binocular fixation of the thrusting hand and avoidance of direct gaze. The hand is thus treated as though it had become more conspicuous. Males show signs of such changes, which are obscured by a progressive locking of attention on the hand, along with which develop head shaking and pecking. These latter three effects, together with later full attacks, may be a consequence of increased persistence in males due to testosterone. In both sexes testosterone facilitates waltzing and three characteristic calls, probably by specific effects. Latencies and dosage dependency are similar in both sexes. Ten changes in behaviour due to testosterone can be explained by as few as five basic effects, both general and specific.
在雌性雏鸟中，睾酮会增加对伸出手的双眼注视以及避免直接对视。因此，这只手被视为变得更加显眼。雄性也表现出此类变化的迹象，但由于对这只手的注意力逐渐锁定，同时还伴随着摇头和啄击行为，这些变化的迹象被掩盖了。后三种效应，连同后来的全面攻击，可能是由于睾酮导致雄性持续性增加的结果。在两性中，睾酮可能通过特定作用促进了华尔兹舞和三种特征性鸣叫。潜伏期和剂量依赖性在两性中相似。由睾酮引起的十种行为变化可以用仅五种基本效应来解释，包括一般效应和特定效应。
