    • Blinding is compromised for transcranial direct current stimulation at 1 mA for 20 min in young healthy adults 

      Turi, Zsolt; Csifcsak, Gabor; Boayue, Nya Mehnwolo; Aslaksen, Per M; Antal, Andrea; Paulus, Walter; Groot, Josephine; Hawkins, Guy E.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-03-19)
      Transcranial direct current stimulation (tDCS) is a non‐invasive brain stimulation method that is frequently used to study cortical excitability changes and their impact on cognitive functions in humans. While most stimulators are capable of operating in double‐blind mode, the amount of discomfort experienced during tDCS may break blinding. Therefore, specifically designed sham stimulation protocols ...

    • Commentary: Transcranial stimulation of the frontal lobes increases propensity of mind-wandering without changing meta-awareness

    • Increasing propensity to mind‐wander by transcranial direct current stimulation? A registered report 

      Boayue, Nya Mehnwolo; Csifcsak, Gabor; Aslaksen, Per M; Turi, Zsolt; Antal, Andrea; Groot, Josephine Maria; Hawkins, Guy E.; Forstmann, Birte U.; Opitz, Alexander; Thielscher, Axel; Mittner, Matthias (Journal article; Tidsskriftartikkel, 2019-01-24)
      Transcranial direct current stimulation (tDCS) has been proposed to be able to modulate different cognitive functions. However, recent meta‐analyses conclude that its efficacy is still in question. Recently, an increase in subjects’ propensity to mind‐wander has been reported as a consequence of anodal stimulation of the left dorsolateral prefrontal cortex (Axelrod et al., Proceedings of the National ...

    • Modeling distracted performance 

      Hawkins, Guy E.; Mittner, Matthias; Forstmann, Birte U.; Heathcote, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-23)
      The sustained attention to response task (SART) has been the primary method of studying the phenomenon of mind wandering. We develop and experimentally test the first integrated cognitive process model that quantitatively explains all stationary features of behavioral performance in the SART. The model assumes that performance is generated by a competitive race between a stimulus-related decision ...

    • A Neural Model of Mind Wandering 

      Mittner, Matthias; Hawkins, Guy E.; Boekel, Wouter; Forstmann, Birte U. (Journal article; Tidsskriftartikkel; Peer reviewed, 2016-06-25)
      The role of the default-mode network (DMN) in the emergence of mind wandering and task-unrelated thought has been studied extensively. In parallel work, mind wandering has been associated with neuromodulation via the locus coeruleus (LC) norepinephrine (LC-NE) system. Here we propose a neural model that links the two systems in an integrative framework. The model attempts to explain how dynamic ...

    • Self-reported mind wandering reflects executive control and selective attention 

      Hawkins, Guy E.; Mittner, Matthias; Forstmann, Birte U.; Heathcote, Andrew (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-06-07)
      Mind wandering is ubiquitous in everyday life and has a pervasive and profound impact on task-related performance. A range of psychological processes have been proposed to underlie these performance-related decrements, including failures of executive control, volatile information processing, and shortcomings in selective attention to critical task-relevant stimuli. Despite progress in the development ...
