Comparing naming, lexical decision, and eye fixation times: word frequency effects and individual differences

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Neuroscience

Background:

• Understanding word recognition is crucial for cognitive psychology and psycholinguistics.
• The word frequency effect, where more frequent words are processed faster, is a well-established phenomenon.
• Investigating this effect across different tasks provides insights into the underlying cognitive mechanisms.

Purpose of the Study:

• To compare the word frequency effect in three distinct tasks: naming, lexical decision, and reading.
• To determine if these tasks yield consistent or divergent data regarding word recognition processes.
• To explore the relationship between the word frequency effect and response times in each task.

Main Methods:

• Participants performed three tasks: word naming, lexical decision, and reading.
• Eye fixation times on target words were measured during the reading task.
• The word frequency effect was analyzed for a common set of words across all tasks and participants.

Main Results:

• Naming and reading tasks (specifically gaze duration) showed similar word frequency effects.
• The lexical decision task exhibited a greater word frequency effect compared to naming and reading.
• A positive correlation was observed between the magnitude of the frequency effect and average response time in all tasks.

Conclusions:

• Both naming and lexical decision tasks provide valuable data on word recognition.
• The findings suggest that these tasks capture cognitive processes consistent with those observed during silent reading.
• Task-specific differences in the word frequency effect highlight variations in processing demands.
