用48只Holtzman白化病大鼠和24只戴帽雌性大鼠进行了6次实验，研究了电击前刺激对电击后痛苦叫声的衰减作用。衰减在4个实验期内和实验期之间保持恒定，并发生在第一次试验中。显著较少的发声发生在休克之前的视觉刺激与3或6秒的跟踪或延迟间隔的发病。抑制发声没有发生（a）当刺激和休克发作是同时的，（B）当刺激抵消刺激，或（c）当刺激是在相同的感觉方式（触觉）作为休克。一个非联想的解释强调感官的相互作用的支持。（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Studied the attenuation of distress vocalizations to shock by a stimulus preceding shock in 6 experiments with 48 Holtzman albino and 24 hooded female rats. Attenuation remained constant within and across 4 experimental sessions and occurred on the 1st trial. Significantly fewer vocalizations occurred when shock was preceded by onset of a visual stimulus with either a 3-or 6-sec trace or delay interval. Inhibition of vocalizations did not occur (a) when onset of both stimulus and shock was simultaneous,(b) when the stimulus was offset of stimulation, or (c) when stimulus was in the same sensory modality (tactual) as shock. A nonassociative interpretation emphasizing sensory interaction is supported.(PsycINFO Database Record (c) 2016 APA, all rights reserved)
