Abstract

The hegemonic use of electric shock as an aversive stimulus limits what is known about the generality of avoidance behavior and related phenomena. The purpose of this study was to investigate the effects of using the hot air blast (HAB) instead of electric shock as an aversive stimulus in avoidance conditioning. Four male Wistar rats were exposed to a discrete-trial procedure. In the first phase, the emission of a lever-press response during a trial was positively reinforced. In the second phase, the same contingency was employed, but an escapable HAB was presented at the end of a trial when no response was emitted. In the third phase, positive reinforcement was suspended and a discrete-trial avoidance procedure was employed. In the fourth phase, HAB presentation was completely suspended. As a result, all subjects learned the avoidance response and showed a marked reduction in its frequency during HAB suspension. These results offer evidence indicating that avoidance behavior is controlled by the HAB, thereby advancing the understanding of the generality of this stimulus as being aversive.

鼠类躲避热气冲击的能力
使用电击作为厌恶刺激的霸权限制了人们对回避行为及相关现象普遍性的了解。本研究的目的是调查在回避条件反射中使用热空气冲击(HAB)而不是电击作为厌恶刺激的效果。研究人员对四只雄性 Wistar 大鼠进行了离散试验。在第一阶段,试验中按下杠杆的反应被正强化。在第二阶段,采用相同的条件反射,但在试验结束时,如果大鼠没有做出任何反应,则会出现一个可逃脱的 HAB。第三阶段,暂停正强化,采用离散试验回避程序。在第四阶段,HAB 的呈现完全暂停。结果,所有受试者都学会了回避反应,并且在 HAB 暂停期间,回避反应的频率明显降低。这些结果提供了证据,表明回避行为是由 HAB 控制的,从而加深了人们对这种刺激具有厌恶性的普遍性的理解。
