Lexical support for phonetic perception during nonnative spoken word recognition.

Area of Science:

• Psycholinguistics
• Cognitive Science
• Second Language Acquisition

Background:

• Native language comprehension is typically more efficient than second language comprehension.
• Lexical factors influence phonetic perception in native language processing.
• The role of lexical support in nonnative phonetic perception remains less understood.

Purpose of the Study:

• To investigate whether nonnative listeners utilize lexical context for phonetic perception.
• To examine the influence of acoustic cues versus lexical context on nonnative phonetic perception.
• To determine the effect of language proficiency on lexical support for phonetic perception.

Main Methods:

• Testing native Hebrew speakers with American English stimuli under varying acoustic-lexical cue conditions.
• Comparing the performance of native Hebrew speakers with native English speakers.
• Assessing native Arabic speakers' ability to use lexical activation for English phonetic perception.

Main Results:

• Nonnative speakers did not show lexical guidance of phonetic perception when acoustic cues conflicted with lexical context.
• Native Hebrew speakers demonstrated lexical support for English phonetic perception when acoustic cues were not conflicting.
• Less proficient Arabic speakers showed no lexical support for phonetic perception, even without conflicting cues.

Conclusions:

• Lexical support for phonetic perception is modulated by second language proficiency.
• Nonnative listeners' ability to use lexical information for phonetic perception differs from native listeners, especially when cues conflict.
• Proficiency is a key factor in the extent to which lexical information drives phonetic perception in a second language.
