The researchers caution against reading the deactivation as evidence of impaired cognitive function. As they put it in the paper, “this deactivation should not be interpreted as a failure of cognitive control capacity.” Instead, the team argues the pattern likely reflects an adaptive shift toward low-effort, automatic processing during passive, low-conflict viewing. They note that participants remained actively engaged throughout the task, skipping disliked clips on roughly 57 percent of trials, which the authors say points to sustained evaluation rather than disengagement or mind-wandering.
