Experiment 1 A mismatch negativity study of visual physical stimulus by a multi-feature paradigm
Objective : The mismatch negativity (MMN) is an event-related potential component that reflects information change detection independent of subject’s attention. In the past,oddball paradigm is used to study MMN, which consume the long time and only one deviation could be detected in one block. N??t?nen optimized the traditionary oddball paradigm, which used to study MMN , and designed the auditory optimal pa...
