Visual memory for scenes is surprisingly robust. We wished to examine whether an analogous ability exists in the auditory domain. Participants listened to a variety of sound clips and were tested on their ability to distinguish old from new clips. Stimuli ranged from complex auditory scenes (e.g., talking in a pool hall) to isolated auditory objects (e.g., a dog barking) to music. In some conditions, additional information was provided to help participants with encoding. In every situation, however, auditory memory proved to be systematically inferior to visual memory. This suggests that there exists either a fundamental difference between auditory and visual stimuli, or, more plausibly, an asymmetry between auditory and visual processing.
对场景的视觉记忆出奇地强大。我们希望研究在听觉领域是否存在类似的能力。参与者听取了各种声音片段,并接受测试以检验他们区分新旧片段的能力。刺激范围从复杂的听觉场景(如台球厅里的交谈声)到孤立的听觉对象(如狗叫声)再到音乐。在某些情况下,会提供额外信息以帮助参与者进行编码。然而,在每种情况下,听觉记忆都被证明在系统上逊于视觉记忆。这表明,要么听觉刺激和视觉刺激之间存在根本差异,要么更有可能的是,听觉处理和视觉处理之间存在不对称性。
