【正文】 e both the target and the flankers correspond to the same response. Examples of incongruent flanker stimuli HHHSHHH and CCCHCCC , where the central target letter and the flankers correspond to opposite responses ? Go/Nogo task ERP實驗設(shè)計 ? 1. 試次數(shù)目： ? P3/N400: 3040 trials per condition (., 30 rare) ? N2pc/ERN: 100200 trials per condition ? P1/N1: 300600 trials per condition ? 60 minutes of “run time” per session ? Runs of 46 minutes with 23 20second breaks – Less makes it inefficient to deal with electrodes, etc. – More leads to fatigue – Some labs do allday sessions with lot of breaks ? SOA過短會導(dǎo)致 ERP成分（特別是早期成分的重疊）；但是過長會浪費計算機的存儲空間，并延長必要的實驗時間 ? 當(dāng)你比較兩種條件的 ERP時，需要確保他們的刺激物理屬性相同，差別僅在于心理因素 ? 需要確保兩種條件的信噪比差異不是太大 ? Never assume that the amplitude and latency of an ERP ponent are linearly or even monotonically related to the quality and timing of a cognitive process. This can be tested, but it should not be assumed 演講完畢，謝謝觀看！
