Abstract

Pigeons peck more frequently on the left key of two keys when food is presented more frequently during the stimulus that reinforces pecks on that key than during the stimulus that reinforces pecks on the right key. This preference can be annulled and reversed by punishing each peck on the left key during the stimulus that reinforces pecks on the left key.

摘要

当食物在强化啄左边键的刺激中比在强化啄右边键的刺激中出现得更频繁时，鸽子在两个键中更频繁地啄左边键。这种偏好可以通过在强化啄左边键的刺激中惩罚每一次啄左边键来消除和反转。
