Context Facilitates the Decoding of Lexically Ambiguous Words for Adult Literacy Learners

Area of Science:

• Cognitive Psychology
• Educational Psychology
• Linguistics

Background:

• Low literacy skills affect a significant portion of US adults, impacting reading comprehension.
• Eye movement studies offer insights into reading behavior but have been underutilized in adult literacy research.

Purpose of the Study:

• To investigate the online reading behavior of adult literacy learners using eye movement tracking.
• To examine how lexical ambiguity, context strength, and context location influence reading patterns.
• To explore the role of vocabulary depth in processing ambiguous words.

Main Methods:

• Collected eye movement data (gaze duration, total time, regressions) from adult literacy learners.
• Manipulated lexical ambiguity, context strength, and context location within sentences.
• Assessed vocabulary depth to understand its correlation with reading behavior.

Main Results:

• Adult literacy learners spent significantly more total time reading ambiguous words than control words.
• Vocabulary depth positively correlated with the processing of lexically ambiguous words.
• Learners with higher vocabulary depth showed greater sensitivity to ambiguity and better context utilization, evidenced by increased reading time and regressions.

Conclusions:

• Contextual information aids lexical processing for adult literacy learners.
• Adult learners demonstrate sensitivity to variations in lexical ambiguity.
• Vocabulary depth is a key factor in effective context utilization and processing of complex words.
