The time-limited influence of sentential context on function word identification

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Understanding how sentential context influences word identification is crucial for psycholinguistics.
• Dutch function words 'te' (to) and 'de' (the) are phonetically similar, making their identification context-dependent.

Purpose of the Study:

• To investigate the temporal dynamics of sentential context effects on the perception of Dutch function words.
• To determine whether syntactic processing influences lexical access or decision-making processes.

Main Methods:

• Listeners identified Dutch words on a [t inverted e]-[d inverted e] continuum under varying contextual biases.
• Experiments manipulated the timing and strength of syntactic disambiguation within sentences.
• Response times were analyzed to differentiate between early and late effects.

Main Results:

• Sentential context significantly affected the identification of 'te' vs. 'de', particularly when disambiguation occurred early.
• Context effects were weaker or absent when disambiguation was delayed or less robust.
• Faster responses showed stronger context effects, suggesting a bias in decision-making.

Conclusions:

• Syntactic processing impacts word identification, but only within a limited time window.
• The findings suggest that context biases decision-making rather than influencing lexical access through feedback loops.
