Implicit semantics gates visual awareness.

The current study asked whether impoverished peripheral vision led to perception immune from word-based semantic influences. We leveraged a peripheral sound-induced flash illusion. In each trial, two or three Mandarin characters were flashed quickly in the periphery with number-congruent or -incongruent beeps. We first successfully replicated the original illusions, showing auditory dominance. For example, when three characters were presented together with two beeps, the observer reported perceiving only two characters. Similarly, an additional beep induced an illusory visual percept. Crucially, when the three characters formed a meaningful word, the lack of a concurrent beep suppressed the awareness to a greater extent. A separate experiment replicated the effect on participants who were unable to recognize the words. When the reading was disrupted by reversing the presentation order, the effect disappeared. These findings demonstrate the capacity of our visual system to extract peripheral linguistic information without conscious word recognition.
