Abstract

Does linguistic information speed up access to consciousness of matching visual information? This question was addressed by Lupyan & Ward (2013), and more recently by Forder, Taylor, Mankin, Scott, and Franklin (2016), and Ostarek and Huettig (2017). In these previous studies, however, target-congruency was either confounded with target predictability, or a paradigm was used that did not directly assess time-to-awareness. Here, we investigate whether congruent linguistic information speeds up access to awareness of matching visual information, using a breaking continuous flash suppression paradigm in which cue-target congruency was not confounded with predictability. In a speeded reaction time task, observers heard spoken color labels (e.g. red) followed by colored targets that were either congruent (red), incongruent (green) or neutral (a neutral non-color word) with respect to the labels. Importantly, and in contrast to previous studies investigating a similar question, the cues were never predictive of the targets. Our results show that RTs were selectively shortened for congruent verbal-visual pairings (and not lengthened for incongruent parings), and that this shortening occurred over a wide range of cue-target intervals. We suggest that linguistic verbal information pre-activates sensory representations, so that, for example, hearing the word ‘tomato’ pre-activates (visual) information internally, making it easier to spot tomatoes among other fruit in a fruit stall.
