聴覚刺激の選択過程における注意の機能について,事象関連脳電位(event-related brain potential, ERP)を指標として検討を行った。特に,非注意刺激の処理過程に注意が及ぼす効果について重点的に調べた。実験2においては,非注意刺激に対して150-300ms潜時帯で出現する陽性波(Pd)が反映する処理過程が,注意痕跡と非注意刺激との比較・照合過程と何らかの関係があるのかという点について,刺激呈示チャンネルの相対的な呈示確率を操作することによって検討した。純音を左右耳に,200-500msの刺激間間隔で無作為な順序で呈示した。チャンネル確率としては,25%,50%,75%の3水準を設けた。被験者には,指定されたいずれかの耳(チャンネル)に注意を向け,時折呈示される周波数のわずかに高い音に対してボタン押し反応をするよう求めた。実験の結果,Pdはチャンネル確率が低いほど増大した。ERP振幅が刺激呈示確率の効果を受けることは,そのERPの発生に何らかの記憶プロセスが関与していることを示している。さらに,確率の低下に従って振幅が増大する方向に確率効果が現れることは,記憶表象と入力刺激との不一致がERPの発生の基盤となっていることも示している。これらの推測と,Pdが処理陰性電位(PN)に連続して出現し得ることを示した先行研究結果を合わぜで考えると,PdはPNに皮映される注意痕跡と非注意刺激との不一致によって生じる電位であることが示された。実験1および実験2の結果から,Pdは注意痕跡と非注意刺激との不一致によって駆動される何らかの制御的処理過程を反映することが推測された。今後は,その処理過程について,より具体的に指摘するための実験が必要である。

When you select a process stimulus, note that the event-related brain potential (ERP) refers to the failure of the operator. In particular, do not pay attention to stimulate the management process, pay attention and pay attention to the key points. Inadvertently stimulating the latent waves of 150-300ms (Pd) reflects the process of monitoring. Note that the response of unattended stimuli is much higher than that of attentive stimuli, and the response rate of the stimuli is higher than that of normal stimuli. 200-500ms stimulation interval was used as a sequential presentation device in the left and right ears. Please make sure that the rate is 25%, 50%, 75%, 3%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 7%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5%, 5 For the victim, specify that you should pay attention to the direction of the noise, and show the number of waves, the number of high-pitched sound, the sound of the high-pitched sound, the number of waves, the number of times, and the number of times. The results show that the accuracy rate of PDFs is low and the accuracy rate is high. The positive rate of ERP amplitude stimulus presentation is affected by the frequency of ERP stimulation. How do you record it? The confirmation rate is low, the amplitude is low, the direction is large, the accuracy is low, and the record shows that the input force stimulation is inconsistent and the ERP is not consistent. The results of the previous study were combined with the results of the previous study. The results of the Pd PN test were not consistent with each other. The results of the study showed that the results of the previous study were consistent with the results of the previous study. The results of the study combined with the results of the previous study. The results of the study show that the results of the previous study show that the results of the study are not consistent. In the first half of this year, the results of the two results, Pd notes that the management process of non-attentive stimulation is reflected in the management process of inconsistency. In the future, we will take care of the process and make specific accusations that it is necessary to do so.
