Speech learning requires precise motor control but it likewise requires transient storage of information to enable the adjustment of upcoming movements based on the success or failure of previous attempts. The contribution of somatic sensory memory for limb position has been documented in work on arm movement, however, in speech, the sensory support for speech production comes both from somatosensory and auditory inputs and accordingly sensory memory for either or both of sounds and somatic inputs might contribute to learning. In the present study, adaptation to altered auditory feedback was used as an experimental model of speech motor learning. Participants also underwent tests of both auditory and somatic sensory memory. We found that although auditory memory for speech sounds is better than somatic memory for speech-like facial skin deformations, somatic sensory memory predicts adaptation, whereas auditory sensory memory does not. Thus, even though speech relies substantially on auditory inputs and in the present manipulation adaptation requires the minimization of auditory error, it is somatic inputs that provide the memory support for learning.

感觉记忆对言语运动学习的贡献。


语音学习需要精确的运动控制，但它同样需要信息的瞬时存储，以便能够根据之前尝试的成功或失败来调整即将到来的动作。躯体感觉记忆对肢体位置的贡献已在手臂运动的研究中得到记录，然而，在言语中，对言语产生的感觉支持来自体感和听觉输入，因此对声音和躯体输入之一或两者的感觉记忆可能为学习做出贡献。在本研究中，适应改变的听觉反馈被用作言语运动学习的实验模型。参与者还接受了听觉和躯体感觉记忆的测试。我们发现，虽然语音的听觉记忆优于类似语音的面部皮肤变形的躯体记忆，但躯体感觉记忆可以预测适应，而听觉感觉记忆则不能。因此，尽管语音在很大程度上依赖于听觉输入，并且在目前的操作适应中需要最小化听觉错误，但为学习提供记忆支持的是躯体输入。
