Lexical precision in skilled readers: Individual differences in masked neighbor priming

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Masked form priming is a key paradigm for studying visual word recognition.
• Individual differences in reading and spelling proficiency can influence word processing.
• Lexical neighborhood density affects word recognition, but its interaction with individual differences is less understood.

Purpose of the Study:

• To investigate the relationship between masked form priming and individual differences in reading and spelling proficiency.
• To examine how spelling ability modulates the effects of lexical neighborhood density on word recognition.
• To explore the implications for theories of visual word recognition and reading skill.

Main Methods:

• Two experiments using masked form priming with university students (N=97 and N=123).
• Experiment 1 assessed neighbor priming for 4-letter words varying in neighborhood density.
• Experiment 2 used 5-letter words and compared neighbor primes with ambiguous and unambiguous partial-word primes.

Main Results:

• Replicated facilitatory priming for low-density neighborhoods.
• Better spellers showed inhibitory priming for high-density neighborhoods, while poorer spellers showed facilitatory priming.
• Spelling ability was selectively associated with inhibitory effects of lexical competition.

Conclusions:

• Spelling proficiency plays a crucial role in modulating lexical competition during visual word recognition.
• Findings support the lexical quality hypothesis, suggesting that higher quality lexical representations support more efficient inhibitory processes.
• The study highlights the importance of considering individual differences in cognitive models of reading and spelling.
