Mind-wandering is a phenomenon detrimental to our behaviour and occurs for a large portion period of time during our waking hours. Although it happens for a large portion of our waking hours, it is still unclear how and why it happens. There appears to be a positive relationship between mind-wandering, the duration of a same task and the amount of effort needed for a task. Jubera-Garcia, Gevers, & Van Opstal (2021) proposed a theory that mind-wandering could be the result of a local depletion of mental resources. 

The present study attempts to investigate whether the amount of mind-wandering is influenced by the type of resource depletion. To test this, 119 participants were divided between two conditions, that either used a global or a local depletion. Mind-wandering was measured through reaction time coefficient of variability (RTCV) and the Phasic Pupillary Response (PPR) during a Alphanumerical Rotation Task (ART). The results of this study show that there was no difference in the amount of mind-wandering between the global and the local condition. This indicates that the type of resource depletion does not influence the amount of mind wandering differently. This study provides evidence against the local resource depletion theory, and therefore, further increases our understanding about resource depletion and mind wandering.
