@article{oai:kitami-it.repo.nii.ac.jp:00006956, author = {田村, 卓哉}, issue = {1}, journal = {北見工業大学研究報告}, month = {Sep}, note = {application/pdf, Many previous studies have reported that latencies and/or amplitudes of late components of Event-Related Brain Potentials (ERPs) are influenced by various psychological parameters. In this study the relationship between those components and target predictability was investigated using the Pseudo-Oddball paradigm. Subjects were asked to look at fifteen digits sequentially and to report the total sum after that. Most of the digits were“0”s (I.e. non-targets). Two or three targets (“1” to“9”) were presented according to three types of schedules, which were varied in regularity or predictability. As its regularity decreased, the amplitude of the frontal negative slow wave to the first target increased, whereas there were no effects on the centro-parietal positive components (P3s). These negative components cannot easily be identified with the Contingent Negative Variation in terms of scalp distribution and so on. They seem to be affected by multiple factors such as predictability of the eliciting targets and the following targets.}, pages = {247--257}, title = {環境内に埋め込まれた構造に対する情報処理心理学的アプローチの可能性: 事象関連電位を用いた標的出現の予測可能性に関する研究}, volume = {34}, year = {2002} }
