Aversive behaviors of rats to the conditioned stimulus in the course of classical conditioning of a light (CS) and electric-shock (US) were analyzed using a stabilimeter. For the Classical Conditioning (CC) group (n = 5), CS was preceded 5 s to US (l s) using delayed conditioning procedure in the 3 daily sessions each of which was consisted of 30 reinforcing trials. For the US group (n = 5), US (l s) was presented at the same time as CC group without any CS. The results showed that the activity of the CC group during CS increased as the trials progressed, but it was not changed in the US group. Thus, animals made various kinds of activities during the CS, and these were not reflexes to the presentation of the CS but were responses that have long latencies.
使用稳定仪分析了大鼠在光(条件刺激,CS)和电击(非条件刺激,US)经典条件反射过程中对条件刺激的厌恶行为。对于经典条件反射(CC)组(n = 5),采用延迟条件反射程序,在每天3节实验课中,CS在US(1秒)前5秒呈现,每节实验课由30次强化试验组成。对于US组(n = 5),US(1秒)与CC组同时呈现,不给予任何CS。结果表明,CC组在CS期间的活动随着试验的进行而增加,但US组没有变化。因此,动物在CS期间会进行各种活动,这些活动不是对CS呈现的反射,而是具有长潜伏期的反应。
