Reaction times collected from online studies are valid measures

Recorded sources
4 sources for · 0 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Evidence from multiple studies indicates that web-based cognitive testing tools can reliably and validly measure reaction times, provided that appropriate technical methods (such as precise JavaScript display timing) are utilized.

The analysis

The retrieved papers include several empirical studies evaluating web-based cognitive assessment tools that measure reaction time (such as SMART and BRAINscreen). These studies demonstrate good reliability, validity, and feasibility for online reaction time assessments. Furthermore, methodological work like Reimers et al. (or paper [3] regarding display timing) addresses historical hardware/browser limitations to ensure online reaction time collection is precise and valid. No papers refute the validity of online reaction times when proper methods are used, leading to a SUPPORTED verdict.

Gáspár Lukács, Andreas Gartus. Precise display time measurement in JavaScript for web-based experiments. 2021. https://doi.org/10.31234/osf.io/jqk8m

Recommends specific JavaScript display timing methods (like 'RAF loops') to achieve high precision in web-based experiments, supporting the technical viability of online reaction time studies.

Katherine E Dorociak, Nora Mattek, Jonathan Lee, Mira I Leese, Nicole Bouranis, Danish Imtiaz, Bridget M Doane, John P K Bernstein, Jeffrey A Kaye, Adriana M Hughes. The Survey for Memory, Attention, and Reaction Time (SMART): Development and Validation of a Brief Web-Based Measure of Cognition for Older Adults.. 2021. https://doi.org/10.1159/000514871

Provides preliminary evidence that web-based cognitive assessments evaluating reaction time (SMART) demonstrate convergent validity and utility in detecting cognitive differences.
