摘要

當執行冗餘任務－刺激隨機出現於視野左側／右側／雙側，如果雙側視野刺激反應時間快於單側視野刺激，即將此現象稱為「冗餘增益」。冗餘增益的有無隨刺激屬性不同而有不同意義，可用來代表兩大腦溝通之指標。可使用不同的理論來解釋此效益，包括競爭模式 、共同活化模式、大腦半球間抑制假說 與雙重注意力假說等，其分別利用訊息的結合度、抑制訊息的傳遞與注意力系統之運作來解釋冗餘增益與大腦溝通之關係。未來在使用、比較或進行相關研究時，仔細探討與分析實驗流程與刺激形式是必要之步驟，才能準確使用「冗餘增益」來回答研究問題。

In simple visual reaction time (RT) tasks, presenting stimuli to both left and right hemifields results in faster response than presenting only one stimulus to one hrmifield. This phenomenon is referred to as redundancy gain. Based on different kinds of stimuli, it could be interpreted diversely as a sign of inter-hemispheric communication. Models including race model, co-activation model, inter- hemispheric inhibition hypothesis, and dual attention hypothesis may be used to explain the effects of redundancy gain on the performance of visual reaction time tasks. These models and hypotheses explain the relationship between redundancy gain and inter-hemispheric communication differently. When investigating redundant tasks, researchers should analyze the methods of experiments and the characteristics of stimuli carefully in order to answer different research questions.
