鹦鹉被训练使用实时自动呼叫识别系统和食物奖励发出特定的呼叫。只有当鸟发出的叫声与模板叫声足够相似时，食物才会跟随在鸟的叫声之后。特定呼叫类型的选择性强化增加了鸟的呼叫模板的相似性，并降低了整体呼叫变化，包括呼叫持续时间。在鸟的表现达到渐近线（即，叫声变得与模板匹配，相似性没有进一步增加）后，引入了叫声区分程序。该程序包括匹配模板和非行进模板试验。为了在与模板不匹配的试验中获得食物，鸟类必须发出与模板呼叫完全不同的呼叫。该过程导致从第一模板调用出现的“新”调用，其逐渐发生而不是突然发生。在第三个过程中，称为双模板匹配训练，鸟类必须将它们的叫声进行到第一个模板叫声（通过点亮左侧LED发出信号）和第二个模板叫声（通过点亮右侧LED发出信号）。在第一和第二模板识别试验中产生的识别通过LED的位置得到很好的控制。这些结果扩展了选择性强化，差异强化，刺激控制的影响，对响应地形的域中的鹦鹉发声。(C)1997年Elsevier Science B.V.
Budgerigars were trained to make a specific call using a real-time automated call recognition system and food reward. Calls produced by the bird were followed by food only if they were similar enough to a template call. The selective reinforcement of a particular call type increased the similarity of the bird's call to the template and decreased overall call variation, including call duration. After the birds' performance reached asymptote (i.e. the calls became matched to the template with no further increase in similarity), a call differentiation procedure was introduced. This procedure consisted of both matching-to-template and non-marching-to-template trials. In order to receive food in non-matching-to-template trials; the birds had to produce a call that was sufficiently different from the template call. This procedure resulted in a 'new' call emerging from the first template call which occurred gradually rather than abruptly. In the third procedure, called two-template matching training, the birds had to march their calls to the first template call (signaled by illuminating the left LED) and to the second template call (signaled by illuminating the right LED). The calls produced in both first and second template call trials were well controlled by the position of the LED. These results extend the effects of selective reinforcement, differential reinforcement, and stimulus control on response topographies to the domain of vocalizations in budgerigars.
