有人假设，听觉时间分辨率差与儿童的语言学习问题以及老年人在噪音中的言语感知问题有关。我们发现，在年轻人中，短音段之间偶尔出现的无声间隙会引起失配负效应(MMN)。我们还使用MMN测量了与行为阈值非常一致的差距检测阈值。在阈值附近，MMN随着间隙尺寸一毫秒一毫秒的增加而增加。测量时间分辨率的MMN方法不仅可靠，而且可以在整个生命周期内同样应用，因为它不需要参与者的注意或行为反应。我们现在可以研究婴儿期的时间分辨率。
It has been hypothesized that poor auditory temporal resolution is related to language-learning problems in children as well as problems with speech perception in noise in the elderly. We show that the presence of occasional silent gaps between short tone pips elicits mismatch negativity (MMN) in young adults. We also measured gap-detection thresholds with MMN that agree well with behavioural thresholds. Near threshold, the MMN increases as the gap size increases millisecond by millisecond. The MMN methodology for measuring temporal resolution is not only robust, but can be applied identically across the life span as it does not require the attention of participants or a behavioural response. We are now in a position to examine temporal resolution in infancy.
