List context effects on masked phonological priming in the lexical decision task

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Computational Linguistics

Background:

• Visual word recognition involves processing orthographic and phonological information.
• Masked priming experiments are used to study the time course of word processing.
• Homophones and pseudohomophones represent different types of lexical relationships.

Purpose of the Study:

• To investigate how different types of nonword foils affect priming effects for homophones and pseudohomophones.
• To examine the role of orthographic and phonological regularity in masked priming.
• To test the predictions of the bimodal extension of the multiple readout model.

Main Methods:

• A lexical decision task was employed.
• Participants responded to target words preceded by briefly presented masked primes.
• Primes included homophones and pseudohomophones of target words.
• Nonword foils varied in orthographic regularity (regular, irregular, pseudohomophones).

Main Results:

• Pseudohomophone priming effects were consistent across different nonword foil types.
• Homophone priming effects varied: facilitatory with regular nonwords, inhibitory with pseudohomophones, and null with irregular nonwords.
• A dissociation was observed in how nonword foils modulated homophone versus pseudohomophone priming.

Conclusions:

• Nonword foil characteristics significantly influence homophone priming but not pseudohomophone priming.
• The findings support a bimodal model of visual word recognition where orthographic and phonological pathways interact.
• This research clarifies the interplay between form-based and sound-based processing in lexical access.
