Reading homographs: orthographic, phonologic, and semantic dynamics.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Understanding word meaning access is crucial for cognitive science.
• Homographs and homonyms present unique challenges in word recognition due to multiple meanings.
• Previous research has explored factors influencing lexical access but requires further investigation into phonological influences.

Purpose of the Study:

• To compare reading processes for homographs, homonyms, and control words.
• To investigate the role of phonological information in accessing word meanings.
• To examine how contextual cues affect the processing of words with multiple meanings.

Main Methods:

• Experiment 1: Naming reaction times were measured for homographs, homonyms, and control words.
• Experiments 2 & 3: An association judgment task was used, varying the presentation order of ambiguous words and their disambiguating associates.
• Analysis focused on reaction times and accuracy to assess processing costs.

Main Results:

• Naming reaction times were significantly slower for homographs compared to homonyms and control words.
• Processing costs for subordinate meanings of homographs persisted regardless of context.
• For homonyms, processing costs associated with subordinate meanings disappeared when context was provided by preceding associates.

Conclusions:

• Phonological information plays a priority role in accessing word meanings.
• The perception of words is shaped by the interaction of low-level (e.g., phonology) and high-level (e.g., context) constraints.
• Contextual information is more effective in resolving ambiguity for homonyms than for homographs.
