Office workers consistently report greater productivity in the workplace when standing compared to sitting (Chambers et al., 2019; MacEwan et al., 2015; Mantzari et al., 2018). In contrast, laboratory studies report inconsistent evidence that posture (sitting vs. standing) affects cognitive performance, usually operationalized as selective attention (Caron et al., 2020; 2022; Rosenbaum et al., 2017; Smith et al., 2019). The present work assessed whether the discrepancy between workplace and laboratory findings is because workplace tasks are more difficult than the tasks used in laboratory research. Three visual search experiments are reported. Search difficulty was increased in Experiments 1 and 2 and posture difficulty was increased in Experiment 3. There was no evidence that posture affected attention in any of the experiments suggesting that the failure to find an effect of posture on attention in previous work was not due to the task difficulty.
