音调模式被传递到17个主题指示阅读自选书，忽略听觉刺激。标准模式包含8个频率不同的50 ms片段。与标准图形诱发的事件相关脑电位（ERP）相比，图形内单个片段的不频繁变化引起ERP的负性调制。这种变化包括模式内单个片段的重复或两个片段的互换。由于变化的性质，ERP调制不能用简单的不应机制来解释，也不能假设产生负调制的机制只依赖于光谱而不是时间信息的表示。因此，音调模式的频谱和时间信息由信息处理系统在单个片段的颗粒上表示。
Tonal patterns were delivered to 17 subjects instructed to read a self-selected book and to ignore the auditory stimuli. The standard pattern contained eight 50-ms segments differing in frequency. Infrequent changes of single segments within the pattern elicited negative modulations of the event-related brain potentials (ERPs) as compared with the ERPs elicited by the standard pattern. The change consisted of either a duplication of a single segment or an interchange of two segments within the pattern. Because of the nature of the change, the ERP modulation cannot be explained by a simple refractoriness mechanism or by assuming that the mechanism generating the negative modulation relies on representations of only the spectral but not the temporal information of the pattern. Therefore, the spectral and the temporal information of the tonal patterns were represented by the information processing system on a grain of single segments.
