English Cognitive performance is assumed to be better at the peak of circadian arousal than at off peak. This synchrony effect was repeatedly shown using maintenance tasks (i.e., tasks measuring the ability to store or retain access to information). However, evidence is mixed for interference-control tasks (i.e., tasks measuring the ability to avoid being distracted by irrelevant information). The goal of the present study was to test the synchrony effect for maintenance and interference control. To this end, 189 young participants – who were morning or evening types – performed at on- and off-peak times short-term memory (STM) and working memory (WM) tasks with verbal-numerical and spatial material. Using structural equation modeling, we measured maintenance as common factors from STM and WM tasks. Interference control was measured by separating WM-specific variance from maintenance. Contrary to the expectations, the results showed one verbal-numerical and one spatial maintenance factor across both on- and off-peak times. For interference control, we observed at best a latent change between peaks. To conclude, our findings suggest that the synchrony effect is not as general and robust as the last 30 years of research might put forward.
