A cross linguistic study on orthographic influence during auditory word recognition

Area of Science:

• Cognitive Psychology
• Linguistics
• Neuroscience

Background:

• Learning to read significantly influences how we perceive speech.
• The Orthographic Consistency Effect (OCE) demonstrates faster recognition of consistently spelled words.
• Prior research localized the OCE to the rime level in opaque orthographies.

Purpose of the Study:

• To investigate if the OCE operates at the phonemic level.
• To determine if the OCE is a general phenomenon across alphabetic scripts, including transparent systems.
• To explore the influence of language opacity on the OCE.

Main Methods:

• An auditory lexical decision task was administered to 30 French (opaque) and 30 Spanish (transparent) listeners.
• Participants responded to words and pseudowords with consistent or inconsistent phoneme spellings.
• Reaction times were measured to assess word recognition efficiency.

Main Results:

• An OCE was observed in both French and Spanish, indicated by slower reaction times for inconsistently spelled items.
• However, the OCE was statistically significant only in French, not in Spanish.
• This suggests language-specific factors, like orthographic opacity, influence the effect.

Conclusions:

• Auditory lexical processing is influenced by orthographic information at the phonemic level.
• The OCE may be modulated by the opacity of a language's writing system.
• Further research is needed on highly transparent languages to fully understand literacy's impact on auditory processing.
