Are there Individual Differences in Learning Homophones During Silent Reading?

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Reading Science

Background:

• Lexical expertise, encompassing word representation quality and quantity, is crucial for reading comprehension.
• Understanding how readers learn new words, particularly those with complex phonological properties like homophones, is essential.
• Previous research has explored word learning but less is known about novel homophone acquisition during reading.

Purpose of the Study:

• To investigate the influence of lexical expertise on college students' learning of novel homophones and nonhomophones during reading.
• To examine how the frequency of familiar word mates affects the learning of novel homophone meanings and spellings.
• To determine the role of phonological activation in the learning of new words with homophone properties.

Main Methods:

• Two experiments were conducted using novel homophones and nonhomophones embedded in sentences.
• Experiment 1 used novel homophones with low-frequency familiar word mates; Experiment 2 used high-frequency mates.
• Learning was assessed via post-tests measuring meaning and spelling recognition, with eye movements monitored during reading.

Main Results:

• Participants exhibited greater difficulty learning the spellings of novel homophones compared to nonhomophones across both experiments.
• Learning the meaning of novel homophones was impaired only when they had low-frequency familiar word mates.
• Higher lexical expertise correlated with better novel homophone spelling acquisition when familiar mates were high-frequency.

Conclusions:

• Phonological activation during novel word encounters can impede learning, particularly for homophones under specific conditions.
• Lexical expertise moderates the learning of novel homophone spellings, with high-frequency mates facilitating this process.
• The findings highlight the complex interplay between phonology, lexical knowledge, and word learning during reading.
