我们测试的一般假设，丰富的住房环境是有益的实验室大鼠，褐家鼠。我们使用的行为反应，预期即将到来的奖励作为一个简单的丰富的笼子的奖励属性的措施。为此，应用巴甫洛夫条件反射时间表来宣布即将转移到富集笼中。将预期这种转移的大鼠的反应与预期性接触、转移到标准笼中或强迫游泳的大鼠的反应进行比较。我们还描述了预期反应的行为特征，因为到目前为止，这种行为只有一般性的描述。在预期一个丰富的笼子和性接触的活动和类似的反应分析的行为元素方面的强劲增长表明，评估访问一个丰富的笼子共享一个共同的分母与性接触的看法。由于性接触被普遍认为对大鼠具有高度奖励性质，因此我们得出结论，富集笼也具有高度奖励性。性接触或丰富的笼子的预期反应是明显不同的预期访问一个标准的笼子或强迫游泳会议，表明预期反应是有关的积极性质的刺激。一般来说，预期似乎是可以量化的活动水平所衡量的总频率的行为元素显示。一些行为元素，如探索，运动，唤醒和梳理，似乎更具体地与即将到来的刺激的性质有关。(C)2003年由Elsevier Ltd代表动物行为研究协会出版。
We tested the general assumption that enrichment of the housing environment is rewarding to laboratory rats, Rattus norvegicus. We used the behavioural response in anticipation of a forthcoming reward as a measure of the rewarding property of a simple enriched cage. For this, a Pavlovian conditioning schedule was applied to announce the oncoming transfer to an enriched cage. The response of rats in anticipation of this transfer was compared with that of rats that expected sexual contact, transfer to a standard cage or forced swimming. We also characterized the behavioural profile of the anticipatory response, because until now only general descriptions of this behaviour have been available. The strong increase in activity in anticipation of both an enriched cage and sexual contact and the similar response in terms of the behavioural elements analysed indicate that the appraisal of access to an enriched cage shares a common denominator with the perception of sexual contact. Because sexual contact is generally accepted to have highly rewarding properties to rats, we concluded that the enriched cage is highly rewarding as well. The anticipatory response for sexual contact or an enriched cage was clearly different from the anticipation for access to a standard cage or a forced swim session, indicating that the anticipatory response is related to the positive nature of the stimulus. In general, anticipation appears to be quantifiable by the level of activity measured by the total frequency of behavioural elements displayed. Some behavioural elements, such as exploration, locomotion, arousal and grooming, seem to be more specifically related to the nature of the forthcoming stimulus.
