Orthographic consistency affects spoken word recognition at different grain-sizes

Area of Science:

• Psycholinguistics
• Cognitive Science
• Speech and Hearing Science

Background:

• Previous research indicates that sound-to-spelling consistency impacts spoken word recognition.
• Studies often use rhyme consistency to demonstrate this effect in auditory lexical decision tasks.
• The influence of orthographic regularity on spoken word processing is an active area of research.

Purpose of the Study:

• To investigate the effect of orthographic regularity at a finer grain size (vowel spelling) on auditory word recognition.
• To determine if typical vowel spellings within consistent rhymes facilitate faster recognition compared to less typical spellings.
• To extend findings on feedback consistency to individual orthographic patterns in English.

Main Methods:

• An auditory lexical decision experiment was conducted using English words.
• The study manipulated the typicality of vowel spellings within consistently rhyming words.
• Participants judged whether presented auditory stimuli were words or non-words.

Main Results:

• Participants recognized words with consistently rhyming vowels that had the most typical spelling faster than those with less typical spellings.
• This finding demonstrates that orthographic regularity influences spoken word recognition.
• The effect was observed even when rhyme consistency was controlled.

Conclusions:

• Auditory word recognition is sensitive to orthographic regularities at multiple levels, including individual vowel spellings.
• This extends previous findings on feedback consistency and highlights the interplay between auditory and orthographic processing.
• The results have implications for understanding spoken word recognition models and future research methodologies.
