“…Using linear mixed models, we first found a semantic interference effect in RTs and errors: related distractor words elicited longer RTs and more errors compared to unrelated distractors. In that sense, this finding is similar to what is usually shown in PWI tasks that do not manipulate time pressure (e.g., Hitomi et al, 2021). However, the current manipulation elicited a number of errors, indicating that time pressure increased interference.…”

Disfluency can occur when a speaker faces difficulty in language production, but also as a strategy to stall for time and create an illusion of continuity in speech. To better understand the origin of disfluency, the current study used a drift diffusion model (DDM) in a context of semantic competition. We developed a speeded version of the picture–word interference paradigm, in which participants name pictures while ignoring distractor words. We applied the DDM approach to data from related vs. unrelated distractors but also from fluent vs. disfluent answers (e.g. “apple” vs. “hm...a-apple”). All results were mapped onto the drift rate parameter. Unrelated distractor words resulted in a higher drift rate compared to semantic distractors, and fluent answers resulted in a higher drift rate compared to disfluent answers. Results suggest that picture-word interference taps into the process of spreading activation through the lexical-semantic system. Similarly, disfluency reflects competition between response options, and is not a strategy from the speaker to stall for time to accurately name the picture.

“…Forty-eight black-and-white line drawings were selected from a previous study (Hitomi et al, 2021). Each picture (e.g., piano) was paired with two distractor words: one was semantically (i.e., categorically but not associatively) related (e.g., guitar) and the other was unrelated to the target name (e.g., needle).…”

Semantic interference affects speech production by increasing disfluencies, not errors

Several studies have shown that different types of disfluency occur depending on the language production stage at which people experience difficulties. The current study combined a network task and a picture–word interference task to analyse whether lexical-semantic difficulty triggers errors and disfluencies in connected-speech production. The participants produced more disfluencies in the presence of a semantically related distractor word than an unrelated distractor word, while few semantic errors were made. These results support the hypothesis that difficulties at distinct stages of language production lead to distinct patterns of disfluency, with lexical-semantic difficulties leading to self-corrections and silent pauses. The results also have implications for the role of the monitoring system in connected-speech production.

“…A commonly used paradigm to examine the role of tone and segment in speech processing is the picture-word-interference (PWI) paradigm ( Wong and Chen, 2008 , 2009 , 2015 ; Wang et al, 2018 ; Wong et al, 2018 ; Hitomi et al, 2021 ; Zhang et al, 2022 ). In this paradigm, participants need to name certain pictures presented simultaneously with distractors.…”

Many studies have explored the role of consonant, vowel, and tone in Chinese word identification or sentence comprehension. However, few studies have explored their roles and neural basis during Chinese word production, especially when involving neural basis. The present fNIRS study investigated the neural mechanisms of consonant, vowel, and tone processing during Chinese typing. Participants were asked to name the Chinese characters displayed on a computer screen by typing on a keyboard while hearing a simultaneously presented auditory stimulus. The auditory stimulus was either consistent with the characters’ pronunciation (consistent condition) or mismatched in the consonant, vowel, or tone of the character pronunciation. The fNIRS results showed that compared with the consistent condition (as baseline), the consonant mismatch condition evoked lower levels of oxygenated hemoglobin (HbO) activation in the left inferior frontal gyrus Broca’s triangle and left superior temporal gyrus. Vowel mismatch condition evoked a higher level of HbO activation in the top of the left inferior frontal gyrus and left middle frontal gyrus. The regions and patterns of brain activation evoked by tone mismatch were the same as those of vowel mismatch. The study indicated that consonant, vowel and tone all play a role in Chinese character production. The sensitive brain areas were all in the left hemisphere. However, the neural mechanism of consonant processing differed from vowel processing in both brain regions and patterns, while tone and vowel processing shared the same regions.
