Priming stress patterns in word recognition

Area of Science:

• Psycholinguistics
• Phonology
• Cognitive Science

Background:

• Understanding how stress is represented in the lexicon is crucial for models of speech perception.
• Previous research has yielded mixed results regarding the role of stress in lexical access.

Purpose of the Study:

• To investigate the lexical representation of stress in the Greek language.
• To determine if stress information influences word recognition through priming effects.

Main Methods:

• Conducted five intramodal and cross-modal priming experiments using lexical decision tasks.
• Employed three-syllable primes and targets in auditory and visual modalities.
• Manipulated stress placement on penultimate or antepenultimate syllables.

Main Results:

• No significant stress priming effects were observed for words or pseudowords in accuracy or response latency.
• A control experiment with fragment priming showed stress congruence effects for words but not pseudowords.
• Results suggest stress is not processed independently of segmental information.

Conclusions:

• Lexical representations likely include stress information that is inseparable from segmental specification.
• Findings challenge abstract metrical template theories of stress representation.
• Lexical activation, rather than abstract stress pattern matching, appears to drive word recognition.
