The role of a coda consonant as error trigger in repetition tasks
چکیده انگلیسی

Speech errors are known to exhibit an intrusion bias in that segments are added rather than deleted; also, a shared final consonant can cause an interaction of the initial consonants. A principled connection between these two phenomena has been drawn in a gestural account of errors: Articulatory measures revealed a preponderance of errors in which both the target and intruding gesture are co-produced, instead of one replacing the other. This gestural intrusion bias has been interpreted as an errorful coupling of gestures in a dynamically stable coordination mode (1:1, in-phase), triggered by the presence of a shared coda consonant. Capturing tongue motion with ultrasound, the current paper investigates whether shared gestural composition other than a coda can trigger gestural co-production errors. Subjects repeated two-word phrases with alternating initial stop or fricative consonants in a coda condition (e.g., top cop), a no-coda condition (e.g., taa kaa), and a three-word phrase condition (e.g., taa kaa taa). The no-coda condition showed a lower error rate than the coda condition. The three-word phrase condition elicited an intermediate error rate for the stop consonants, but a high error rate for the fricative alternations. While all conditions exhibited both substitution and co-production errors, a gestural intrusion bias emerged mainly for the coda condition. The findings suggest that the proportion of different error types (substitutions, co-production errors) differs as a function of stimulus type: not all alternating stimulus patterns that trigger errors result in an intrusion bias.
