The Web-based Open-access Reliable Decision on Synonyms (WORDS) English Vocabulary Test

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Educational Measurement

Background:

• Vocabulary knowledge is crucial for understanding language processing.
• Online research necessitates reliable, accessible vocabulary assessments.
• Existing tools may not meet the demands of web-based studies.

Purpose of the Study:

• To develop and validate a new, open-access, online English vocabulary test.
• To create a reliable measure for use in diverse language processing research.
• To provide a freely available tool for researchers globally.

Main Methods:

• Developed the 30-item Web-based Open-access Reliable Decision on Synonyms (WORDS) test.
• Used item response theory analysis to select optimal test items.
• Validated test-retest reliability and internal consistency (Cronbach's α = 0.82) in two participant samples.

Main Results:

• The WORDS test demonstrated good reliability and was validated across different age groups.
• Confirmed that word frequency and age influence vocabulary test performance.
• The test takes approximately 4-5 minutes to complete, facilitating efficient data collection.

Conclusions:

• The WORDS test is a reliable, quick, and accessible tool for assessing English vocabulary knowledge online.
• This open-access resource supports comparative research in language processing and cognitive aging.
• Facilitates large-scale, web-based vocabulary research with ease of use and data comparability.
