      abstract     = {The efficiency of cognition is modulated by energetic
                      factors like effort, fatigue or circadian variation, which
                      affect even the most basic cognitive operations. For
                      instance, speeded detection in simple reaction-time (SRT)
                      tasks usually slows down over time. The literature suggests
                      that either mindlessness due to routinization or mental
                      fatigue due to attentional resource depletion might underlie
                      this decrement. We tested these assumptions in three 25-min
                      visual SRT tasks using easy-to-detect high-intensity and
                      hard-to-detect low-intensity stimuli presented in both
                      blocked and mixed fashion. Mindlessness theory predicts that
                      less monotonous stimulation (i.e. the mixed presentation)
                      would mitigate the time-related decrement for high- and
                      low-intensity stimuli alike, whereas resource-depletion
                      theory predicts opposite effects of mixed presentation on
                      high- versus low-intensity stimuli. Indeed, stimulus
                      intensity and presentation mode cross-interacted
                      significantly, indicating that the performance decline was
                      steeper for high-intensity stimuli but less steep for
                      low-intensity stimuli during mixed compared to blocked
                      presentation, respectively. These results strongly suggest
                      that the time-related efficiency decrement during prolonged
                      SRT performance is related to accumulating mental fatigue. A
                      conjecture is put forward that explains both resource
                      depletion and mindlessness from the perspective of
                      self-regulation. Our study underscores the need to
                      incorporate energetic factors into models of cognition to
                      facilitate their translation into real-world applications.},
