【摘要】：采用ERPs技術(shù),考察了個(gè)體新穎性圖像加工的時(shí)間進(jìn)程。行為結(jié)果表明:新穎性圖像的判斷時(shí)間更長(zhǎng)。ERPs結(jié)果顯示:新穎與非新穎圖像在刺激呈現(xiàn)后190~340ms誘發(fā)出明顯的前額區(qū)N190~340,但在波幅上無(wú)顯著差異;在400~600ms以及600~1000ms,新穎性圖像在頂區(qū)與額-中央?yún)^(qū),特別在右側(cè)半球誘發(fā)出更大的正性偏移(P400~600和LPC)。研究表明:圖像新穎性屬性的識(shí)別主要發(fā)生在涉及圖像特征融合、圖像記憶編碼等多項(xiàng)認(rèn)知活動(dòng)參與的晚期加工階段,并存在半球右側(cè)化效應(yīng)。
[Abstract]:The time process of individual novelty image processing was investigated by ERPs technique. The results of behavior showed that the judgment time of novelty images was longer. ERPs results showed that 190~340ms induced obvious N190 鈮，
