为了研究早期视觉体验对生物运动（BM）偏好的影响，将新孵化的小鸡暴露于点光动画（由相同光点组成的视觉刺激），该动画描绘了母鸡的以下特征：行走的母鸡（BM刺激），旋转的母鸡（非BM刺激），钟摆刺激，随机运动刺激和静止模式。然后在二元选择任务中对小鸡进行测试，在走母鸡和走母鸡刺激之间进行选择。如果男性接受过除固定模式刺激之外的任何动画训练，他们都会表现出对BM的偏好，这表明BM偏好不是习得的，而是由运动刺激诱导的。我们发现，在训练中的方法的数量和测试中的偏好之间存在显着的正相关关系，但单独的运动并没有引起对BM的偏好。与此相反，女性表现出特别强烈的偏好走母鸡的刺激，但只有当他们已经与它进行了培训。此外，女性（而不是男性）训练与随机运动表现出更喜欢走母鸡走猫（一个生物运动动画描绘了一只猫），可能表明女性比男性更容易。用固定模式训练的小鸡和未经训练的对照组没有表现出显着的偏好。BM偏好的诱导进行了讨论的性别差异可能的生态背景。
To examine the effects of early visual experience on preference for biological motion (BM), newly hatched chicks were exposed to a point-light animation (a visual stimulus composed of identical light points) depicting the following features of a hen: a walking hen (a BM stimulus), a rotating hen (a non-BM stimulus), a pendulum stimulus, a random motion stimulus and a stationary pattern. Chicks were then tested in a binary choice task, choosing between walking-hen and rotating-hen stimuli. Males exhibited a preference for BM if they had been trained with any animation except the stationary pattern stimulus, suggesting that the BM preference was not learned, but induced by motion stimuli. We found a significant positive correlation between the number of approaches in training and the preference in the test, but locomotion alone did not cause preference for BM. In contrast, females exhibited a particularly strong preference for walking-hen stimuli, but only when they had been trained with it. Furthermore, females (but not males) trained with random motion showed a preference for walking hen over walking cat (a biological motion animation depicting a cat), possibly suggesting that females are choosier than males. Chicks trained with a stationary pattern and untrained controls did not show a significant preference. The induction of BM preference is discussed in terms of possible ecological background of the sex differences.
