对非人类灵长类动物记忆能力的研究一直显示，与视觉或触觉刺激相比，听觉相对较弱：学习听觉记忆任务需要大量训练，受试者只能在短时间内保留听觉信息。人类听觉记忆是否存在类似的缺陷仍然是一个悬而未决的问题。在目前的研究中，短期记忆范式被用来测试人类受试者的保留简单的听觉，视觉和触觉刺激，仔细等同的可辨别性，刺激暴露时间，和时间动态。平均准确性没有显着差异，在非常短的保留时间间隔（1-4秒）的感觉方式。然而，在较长的保留间隔（8-32秒），听觉刺激的准确性大大低于视觉和触觉刺激。为了扩展这些发现的生态有效性，第二个实验测试了对日常生活中可能遇到的复杂自然刺激的识别记忆。受试者能够识别所有的刺激时，保留是不需要的，然而，识别准确性延迟一段时间后再次为听觉相比，视觉和触觉刺激。因此，这两个实验的结果提供了一个人类平行的模式，在非人类灵长类动物中观察到的结果。结果解释光的神经心理学数据从非人类灵长类动物，这表明听觉，视觉和触觉记忆介导的嗅周和内嗅皮层的程度的差异。
Studies of the memory capabilities of nonhuman primates have consistently revealed a relative weakness for auditory compared to visual or tactile stimuli: extensive training is required to learn auditory memory tasks, and subjects are only capable of retaining acoustic information for a brief period of time. Whether a parallel deficit exists in human auditory memory remains an outstanding question. In the current study, a short-term memory paradigm was used to test human subjects’ retention of simple auditory, visual, and tactile stimuli that were carefully equated in terms of discriminability, stimulus exposure time, and temporal dynamics. Mean accuracy did not differ significantly among sensory modalities at very short retention intervals (1–4 s). However, at longer retention intervals (8–32 s), accuracy for auditory stimuli fell substantially below that observed for visual and tactile stimuli. In the interest of extending the ecological validity of these findings, a second experiment tested recognition memory for complex, naturalistic stimuli that would likely be encountered in everyday life. Subjects were able to identify all stimuli when retention was not required, however, recognition accuracy following a delay period was again inferior for auditory compared to visual and tactile stimuli. Thus, the outcomes of both experiments provide a human parallel to the pattern of results observed in nonhuman primates. The results are interpreted in light of neuropsychological data from nonhuman primates, which suggest a difference in the degree to which auditory, visual, and tactile memory are mediated by the perirhinal and entorhinal cortices.
