Subcategorical phonetic mismatches and lexical access

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Auditory Perception

Background:

• The role of phonetic analysis in word perception remains debated.
• Previous research suggested lexical decisions rely on unanalyzed patterns, with misleading cues delaying judgments.
• Current studies explore different acoustic cues and their impact on word processing.

Purpose of the Study:

• To investigate the timing of phonetic analysis in word perception.
• To examine how misleading phonetic information affects lexical decision and auditory naming tasks.
• To determine if phonetic conflicts are resolved before or after lexical access.

Main Methods:

• Auditory lexical decision task with misleading phonetic cues.
• Auditory naming task to assess performance with less demanding decision stages.
• Comparison of response times under different phonetic conflict conditions.

Main Results:

• Misleading phonetic information slowed responses in the lexical decision task for both words and nonwords.
• In the auditory naming task, only slower responses were affected by misleading information.
• Phonetic conflicts influenced processing, but the effect varied by task demands.

Conclusions:

• Phonetic conflicts appear to be resolved prior to lexical access.
• The findings challenge theories assuming fully specified phonemic strings as initial input.
• Auditory processing involves a stage where phonetic information is integrated before word recognition.
