Examining the Relationship Between Multiple Tests of Receptive Vocabulary

Area of Science:

• Psycholinguistics
• Educational Technology
• Cognitive Psychology

Background:

• Traditional receptive vocabulary assessments often require in-person administration by trained professionals.
• The need for accessible, scalable, and remote vocabulary measurement tools is growing.

Purpose of the Study:

• To compare a standard in-person receptive vocabulary test with self-administered alternatives.
• To evaluate the efficacy of automated vocabulary assessments in mirroring results from traditional methods.

Main Methods:

• Fifty-three participants completed the Peabody Picture Vocabulary Test (PPVT) via remote video call.
• Participants also undertook four fully automated, self-administered receptive vocabulary measures.
• Control tasks unrelated to vocabulary were included for comparison.

Main Results:

• Moderate correlations were observed between most receptive vocabulary measures (r ≈ .50-.70).
• Control tasks showed weak correlations with vocabulary measures, as expected.
• Subsets of items from self-administered measures correlated highly with the PPVT (r > .80) after resampling.

Conclusions:

• Self-administered vocabulary tasks, when using specific item subsets, can yield results comparable to the in-person PPVT.
• Automated, self-administered measures offer a viable alternative for researchers needing to assess receptive vocabulary remotely.
• The choice of specific automated tasks may depend on individual research needs, given varying correlations with the PPVT.
