Abstract

Reaction time is believed to be a good indicator of the speed and efficiency of mental processes and is a ubiquitous variable in the behavioral sciences. Despite this popularity, there are numerous issues associated with using reaction time (RT), specifically in differential and developmental research. Here, we identify and focus on two main problems-unreliability and sensitivity to speed-accuracy interactions. The use of difference scores is a primary factor that leads to many RT measures having demonstrably low reliability, and RT measures in general often do not properly account for speed-accuracy interactions. Both factors jeopardize the validity and interpretability of results based on RT. Here, we evaluate conceptually and empirically how these issues affect individual differences research. Although the empirical evidence we provide are primarily within the domains of attention control and task switching, we highlight examples from various other areas of psychological inquiry. We also discuss many of the statistical and methodological alternatives available to researchers conducting correlational studies. Ultimately, we encourage researchers comparing individuals of differing cognitive and developmental levels to strongly consider using these alternatives in lieu of RT, specifically RT difference scores.

  • Difference scores are inherently poor in reliability.

    “One complication is that the testing effect is a difference score between a condition that receives retrieval practice and one that does not, and difference scores are inherently poor in reliability (Draheim et al. 2019).”

    From Practicing Retrieval Facilitates Learning (2021) · cites this paper as Draheim et al. 2019

  • Treating RT and accuracy as distinct outcomes does not appropriately account for the speed-accuracy trade-off that exists between the two parameters.

    “However, treating RT and accuracy as distinct outcomes does not appropriately account for the speed-accuracy trade-off that exists between the two parameters24,25.”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
