在無意識狀態下,我們的視覺訊息能整合到那種程度仍有很大的爭議。後 遮蔽法和兩眼交互競爭法長久以來被用來研究此一課題。但不同刺激形態的效 果仍不清礎。在本實驗中我們利用連續閃爍刺激壓抑法,利用中文字和其相関 或不相關的圖片做序列的呈現當作刺激物,並以蒙德里安圖閃爍呈現做為抑制, 以標的物突破抑制被覺知的反應時間長短,作為有無字圖意義整合效果的評 量。
我們實驗的結果並無顯著的效果,這可能是因為連續閃爍刺激壓抑法的抑 制效果太強而使刺激訊息上傳受阻,不夠深,或訊息量不夠,因而使和由上而 下的神經訊息無法完全整合,使字圖的意義在無意識下,無顯著整合的效果。 我們將提出改進之道,希望對未來的研究有幫助。

To what extent unconscious information can be process and integrated is still of great debate. Backward masking (BM) and interocular suppression had been widely used to probe this problem for a long time. But the cross form effect of word and picture remain unclear. In this dissertation we applied CFS paradigm to study this problem. The difference of response time (RT) to breakthrough the suppression under congruent and incongruent condition was used as an indicator of the effect of semantic integration. We supposed that perception may occur by multilevel neuro circuit connection of bottom-up and top-down information to achieve semantic integration of word and picture .
However our results did not showed significant congruency effect of picture to word and no evidence of integrated effect or accumulation effect in cross-form (word-picture-word) condition. The absence of congruent effect of the stimuli from different form may implicit either failure in neural information transformation or failure in integrated with top down information. At last we would like to make some modifications of our paradigm for future research in this topic.
