Both native and non-native disfluencies trigger listeners' attention

摘要: Disfluencies (such as uh and uhm) are a common phenomenon in spontaneous speech. Rather than filtering these hesitations from the incoming speech signal, listeners sensitive to disfluency have been shown actually use disfluencies for comprehension. For instance, found beneficial effects on listeners’ memory. Accumulating evidence indicates that attentional mechanisms underlie this effect: upon encountering disfluency, raise their attention signal. The experiments reported here investigated whether of also hold when listening non-native speaker. Recent studies perception suggest prediction attenuated This attenuation may be result being familiar with frequent more variant incidence If modulate effect memory speaker, it would indicate certain amount control part listener over how affect attention, thus Furthermore, argue against hypothesis comprehension rather automatic fashion (cf. Temporal Delay Hypothesis). Using Change Detection Paradigm, we presented participants three-sentence passages sometimes contained filled pause (e.g., “... patient wound was...”). After each passage, saw transcript spoken passage which one word had substituted “wound” > “injury”). In our first experiment, were accurate recalling words previously heard (i.e., detecting change) if preceded by (relative fluent passage). Our second experiment - using materials demonstrated uh’s elicited an same magnitude direction: new listened speaker producing passages, they disfluent (as compared fluent) trials. These data that, levels irrespective (non-)native identity Whereas speech, no such modulation was present data, potentially constraining role processing. current study emphasizes central account
