[Visual and phonological access to the mental lexicon]
Phonetica
|January 1, 1984
Summary
This study shows that people flexibly use phonological coding in lexical decision tasks, adapting based on whether it helps or hinders word recognition. Faster word identification occurred when phonological coding was not used, suggesting direct visual access to the mental lexicon.
Area of Science:
- Psycholinguistics
- Cognitive Psychology
- Neuroscience
Context:
- Investigating the mental lexicon and word recognition processes.
- Examining the role of phonological coding in lexical decision tasks.
- Exploring the interplay between visual and phonological information during language processing.
Purpose:
- To determine if the mental lexicon is accessed directly via a visual code or through phonological mediation.
- To assess whether phonological coding is a mandatory or flexible process in lexical decisions.
- To evaluate the timing of phonological coding relative to lexical access.
Summary:
- Lexical decision experiments revealed that participants strategically employed phonological coding when beneficial and avoided it when detrimental.
- Response times were faster when participants did not rely on phonological codes, supporting quicker visual access to the mental lexicon.
- Findings indicate that lexical access can involve variable coding operations, aligning with models of post-lexical or parallel phonological coding, but not mandatory pre-lexical coding.
Impact:
- Challenges models that assume mandatory prelexical phonological coding.
- Supports theories allowing for flexible and context-dependent coding strategies in word recognition.
- Provides evidence for the dynamic nature of accessing the mental lexicon, accommodating both visual and phonological pathways.
