Response Durations: A Flexible, No-Cost Tool for Psychological Science

Response durations for simple key presses are an easily available but heavily underused measure. Whereas response times dominate the toolbox of experimental psychologists and cognitive modelers alike, any study with standard key-press responses also allows for the measurement of such durations as the time from response onset to response offset. Moreover, response times and durations are decidedly independent, so response durations hold great promise as a means to uncover unique perspectives on cognitive processing. We showcase recent observations and corresponding theoretical frameworks to highlight that this inconspicuous measure deserves much more attention than it has attracted so far. Given that it comes at no extra cost for common experimental setups, any researcher is well advised to consider adding the measure of response duration to their empirical toolbox.
