学习困难的ERP研究

Event-Related Potentials in Children with Learning Disabilities

事件相关脑电位(Event-related potentials,ERPs)是研究心理学和认知神经科学的重要技术手段,将该技术用于学习困难的脑机制的研究,有助于发现学习困难的神经机制。研究表明,学习困难者的P300波幅较小,潜伏期较长。学习困难者的MMN波幅比控制组小,在信息的自动加工方面存在缺陷。在单词命名任务中,学习困难者的N400较小,而且不同类型学习困难者的波幅和潜伏期存在明显差异。

In the research the authors found, children with learning disabilities had a smaller P300 and a longer latencies. They had and smaller MMN than the control group. Their N400 was smaller in single word naming tasks. And different types of learning disabilities were obviously different in amplitudes and latencies.
