Examining the difference in error detection when listening to native and non-native speakers

Area of Science:

• Psycholinguistics
• Sociolinguistics
• Cognitive Science

Background:

• Increasing global communication involves non-native speakers.
• Understanding foreign-accented speech processing is crucial.
• Listeners may encounter grammatical or word-choice errors in non-native speech.

Purpose of the Study:

• To investigate how listeners process grammatical and word-choice errors.
• To compare error processing between native and non-native speakers.
• To determine the impact of non-native accents on language comprehension.

Main Methods:

• A self-paced listening task was employed.
• Reaction times to target words were measured.
• Participants processed sentences with no errors, grammatical errors, or word-choice errors, spoken by native and non-native speakers.

Main Results:

• Slower reaction times were observed for grammatical and word-choice errors compared to control sentences.
• Error processing was significantly slower for non-native speech.
• Both grammatical violations and contextual word-choice errors prolonged processing time.

Conclusions:

• Errors in non-native speech require additional processing time for listeners.
• Foreign-accented speech, particularly with errors, presents a greater challenge to language processing.
• These findings highlight the cognitive load associated with understanding non-native speakers.
