The present study evaluated the viability of a classical conditioning procedure with an air puff as unconditioned stimulus for the hearing assessment of multiply handicapped children and adolescents. All subjects were also exposed to operant conditioning, which consisted of a modified visual reinforcement audiometry (VRA) procedure or involved edible reinforcement contingent on a reaching response (for blind subjects). The findings indicate that the classical conditioning procedure was successful with 21 of the 23 subjects, whereas operant conditioning succeeded with 15 of the subjects. Thresholds obtained with classical conditioning were mostly equal to or within 10 dB of those obtained with operant conditioning and also matched previously available hearing estimates. These findings seem to suggest that the classical procedure can be a useful behavioral alternative for audiological assessment.
本研究评估了一种经典条件作用程序的可行性，该程序以吹气作为无条件刺激，用于对多重残疾儿童和青少年进行听力评估。所有受试者还接受了操作性条件作用，包括改良的视觉强化测听法（VRA）程序，或针对盲童受试者的基于伸手反应的可食用强化法。研究结果表明，23名受试者中有21名通过经典条件作用程序取得成功，而通过操作性条件作用程序成功的受试者有15名。通过经典条件作用获得的阈值大多与通过操作性条件作用获得的阈值相等或相差在10分贝以内，并且也与之前可用的听力估计值相符。这些研究结果似乎表明，经典程序可以成为听力评估中一种有用的行为替代方法。
