失配负波(MMN)是听觉事件相关脑电位的一个组成部分，即使当受试者被指示忽略刺激的听觉通道时，也会对同类声音序列的物理特性的罕见变化做出反应。已经提出(例如，Naatanen，1990)MMN是由大脑检测异常声音和先前标准声音之间的差异的自动过程产生的。然而，目前还不清楚所涉及的记忆形式与记忆系统的其余部分有何关系。本研究表明，为了响应音调频率的变化而诱发MMN，标准音调的表征必须同时(A)在记忆中被良好地确立为标准。以及(B)处于当前活动状态。讨论了记忆表征的生理和心理方面的关系。
The mismatch negativity (MMN) is a component of the auditory event-related brain potential that occurs in response to infrequent changes in the physical properties of homogeneous series of sounds, even when subjects are instructed to ignore the auditory channel of stimulation. It has been proposed (e.g., Naatanen, 1990) that the MMN is generated by an automatic process in which a difference between the deviant sound and the previous, standard sound is detected by the brain. However, it is unclear how the form of memory involved is related to the rest of the memory system. The present study indicates that, for an MMN to be elicited in response to a change in tone frequency, the representation of the standard tone must be both (a) well-established as a standard in memory. and (b) in a currently active state. The relation between physiological and psychological aspects of memory representation is discussed.
