錯配負波與聽覺模式分段的產生：重探Sussman與Gumenyuk（2005）範式

// The mismatch negativity emergence with auditory pattern segmentation: A revisit of the paradigm by Sussman and Gumenyuk (2005)

本研究探討群組間間隔對音調變化不匹配負波（MMN）反應的影響｜使用AAAAB音調序列比較有無群組間隔兩種條件，發現有間隔時MMN反應穩定，無間隔時狹窄刺激起始非同步（SOA）下MMN減弱｜結果顯示群組間隔能強化聽覺群組表徵，避免MMN反應下降，對理解聽覺處理機制具重要意義。

// This study examined how inter-group intervals affect mismatch negativity (MMN) responses to pitch changes using the AAAAB tone sequence. Two conditions were tested: with and without inter-group intervals. Results showed that inter-group intervals preserved MMN responses regardless of stimulus onset asynchrony (SOA), while absence of intervals reduced MMN at narrow SOAs. The findings suggest inter-group intervals enhance auditory group representation, preventing MMN reduction.
