Pigeons were trained to peck one key when presented with white noise at any of five intensities lower than a reference intensity, and to peck another key when presented with white noise at any of five intensities greater than the reference intensity. The shape of the stimulus control curves (proportion of responses to one key versus stimulus intensity) changed from a horizontal line at the beginning of training to the sigmoid form of typical psychometric functions at the end of training. The development of stimulus control is described in terms of a model based on the theory of signal recognition and a concept of attention.
鸽子接受训练，当呈现低于参考强度的五种强度中任何一种的白噪声时，啄一个按键；当呈现高于参考强度的五种强度中任何一种的白噪声时，啄另一个按键。刺激控制曲线的形状（对一个按键的反应比例与刺激强度的关系）从训练开始时的水平线，在训练结束时变为典型心理测量函数的S形。刺激控制的发展是根据基于信号识别理论和注意力概念的模型来描述的。
