Phoneme-Order Encoding During Spoken Word Recognition: A Priming Investigation

Area of Science:

• Psycholinguistics
• Auditory Perception
• Cognitive Science

Background:

• Spoken word recognition involves processing sequences of sounds.
• The role of phoneme position in auditory word recognition is not fully understood.
• Priming paradigms are used to investigate cognitive processes in language.

Purpose of the Study:

• To investigate the effect of transposed-phoneme priming on auditory lexical decisions.
• To determine if priming effects differ between long-term and short-term exposure.
• To explore the contribution of position-independent phonemes in spoken word recognition.

Main Methods:

• Three experiments using auditory lexical decision tasks.
• Stimuli included target words and prime words with transposed first and last phonemes.
• Varying temporal succession (long-term vs. short-term) and control conditions were employed.

Main Results:

• No transposed-phoneme priming effect was observed in long-term priming.
• A significant transposed-phoneme priming effect was found in short-term priming experiments.
• The effect persisted even when controlling for shared vowels or consonants in incorrect positions.

Conclusions:

• Short-term, but not long-term, exposure to transposed-phoneme primes facilitates spoken word recognition.
• Findings support the hypothesis that phonemes contribute to word recognition irrespective of their precise sequential position.
• This suggests a degree of position-independent processing in the auditory system for phonemes.
