dc.description.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-perception task measuring participants’ perception
of isolated words in noise. Our results show that categorization gradiency does not predict participants’ performance
in the speech-in-noise task. However, higher gradiency predicted higher likelihood of recovery
from temporarily misleading information presented in the VWP task. These results suggest that gradient
activation of speech sound categories is helpful when listeners need to reconsider their initial interpretation
of the input, making them more efficient in recovering from errors. | es_ES |
