Semantic Priming Data from Ocular Lexical Decision Experiments

Two eye-tracking experiments replaced manual responses with eye-movement responses in a lexical decision task. The study, authored by Peter C. Gordon from the University of North Carolina at Chapel Hill, evaluated the contribution of task goals and response mode to semantic priming. Gaze durations showed robust semantic priming, with the effect concentrated in the slow tail of the response time distribution.

Use Cases

• Modeling the time course of semantic priming based on eye-tracking response times.
• Comparing manual and ocular response modes in lexical decision tasks as described in the experiments.
• Analyzing the distribution of priming effects using Ex-Gaussian fits to response time data.
• Investigating task-related influences on word recognition using the ocular lexical decision paradigm.

Strengths

• Data is derived from two controlled eye-tracking experiments with specific task designs.
• Response times are compared to manual lexical decision data from the English Lexicon Project.
• Analysis includes Ex-Gaussian distribution fits to characterize the priming effect.

Limitations

• Row count, column names, and sample data are unknown, limiting suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
