Gradient activation of speech categories facilitates listeners' recovery from lexical garden paths, but not perception of speech-in-noise.

ABSTRACT: Listeners activate speech-sound categories in a gradient way, and this information is maintained and affects activation of items at higher levels of processing (McMurray et al., 2002; Toscano et al., 2010). Recent findings by Kapnoula et al. (2017) suggest that the degree to which listeners maintain within-category information varies across individuals. Here we assessed the consequences of this gradiency for speech perception. To test this, we collected a measure of gradiency for different listeners using the visual analogue scaling (VAS) task used by Kapnoula et al. (2017). We also collected 2 independent measures of performance in speech perception: a visual world paradigm (VWP) task measuring participants' ability to recover from lexical garden paths (McMurray et al., 2009) and a speech
