La memoria de trabajo apoya la acomodación rápida del hablante y del acento: una investigación de las diferencias...

Área de la Ciencia:

• Cognitive Psychology; Auditory Perception; Psycholinguistics

Sus antecedentes:

• Listeners rapidly adapt to speaker variability in multitalker environments.; This adaptation incurs processing costs, exacerbated by accent differences.; Individual differences in cognitive abilities may influence these costs.

Objetivo del estudio:

• Investigate the role of working memory capacity and attentional control in processing costs during talker switches.; Examine how these cognitive factors affect adaptation to native (L1 American) and non-native (L2 Mandarin) accents.; Determine predictors of trial-to-trial accommodation costs.

Principales métodos:

• A dual-task experiment involving a primary listening task and a secondary non-linguistic task.; Assessment of working memory capacity using the Word Auditory Recognition and Recall Measure.; Measurement of attentional control via the Trail Making Test and Stroop Test.

Principales resultados:

• Lower working memory capacity correlated with slower responses and reduced accuracy on talker-switch trials.; Attentional control measures did not predict talker-switching costs.; A marginal interaction suggested better attentional control improved L2 accent recognition accuracy.

Conclusiones:

• Working memory capacity is critical for rapid, trial-to-trial talker accommodation.; Attentional control may broadly support L2 accent processing, but not rapid adaptation.; Individual cognitive differences significantly impact auditory accommodation in complex listening situations.
