In general, stimuli that are familiar and recognizable have an advantage of predominance during binocular rivalry. Recent research has demonstrated that familiar and recognizable stimuli such as upright faces and words in a native language could break interocular suppression faster than their matched controls. In this study, a visible word prime was presented binocularly then replaced by a high-contrast dynamic noise pattern presented to one eye and either a semantically related or unrelated word was introduced to the other eye. We measured how long it took for target words to break from suppression. To investigate word-parts priming, a second experiment also included word pairs that had overlapping subword fragments. Results from both experiments consistently show that semantically related words and words that shared subword fragments were faster to gain dominance compared to unrelated words, suggesting that words, even when interocularly suppressed and invisible, can benefit from semantic and subword priming.
一般来说，熟悉且可识别的刺激在双眼竞争中具有优势。最近的研究表明，诸如正立面孔和母语单词等熟悉且可识别的刺激比其匹配的对照物能更快打破眼间抑制。在本研究中，双眼呈现一个可见的启动词，然后用呈现给一只眼睛的高对比度动态噪声模式取代，同时给另一只眼睛引入一个语义相关或不相关的单词。我们测量了目标词从抑制中打破所需的时间。为了研究词块启动，第二个实验还包括了具有重叠子词片段的词对。两个实验的结果一致表明，与不相关的词相比，语义相关的词和共享子词片段的词能更快获得优势，这表明单词即使在眼间被抑制且不可见时，也能从语义和子词启动中受益。
