Response Task

When the human mind wanders, it engages in episodes during which attention is focused on self-generated thoughts rather than on external task demands. Although the sustained attention to response task is commonly used to examine relationships between mind wandering and executive functions, limited executive resources are required for optimal task performance. In the current study, we aimed to investigate the relationship between mind wandering and executive functions more closely by employing a recently developed finger-tapping task to monitor fluctuations in attention and executive control through objective task performance and periodical experience sampling during concurrent fMRI and pupillometry. Our results show that mind wandering was preceded by increases in finger-tapping variability, which was correlated with activity in dorsal and ventral attention networks. The entropy of random finger-tapping sequences was related to activity in frontoparietal regions associated with executive control, demonstrating the suitability of this paradigm for studying executive functioning. The neural correlates of behavioral performance, pupillary dynamics, and self-reported attentional state diverged, indicating a dissociation between objective and subjective markers of mind wandering. Together, the investigation of these relationships at both the behavioral and neural level provided novel insights in the identification of underlying mechanisms of mind wandering.

Mental Focus

Mind-wandering is a state where our mental focus shifts towards task-unrelated thoughts. While it is known that mind-wandering has a detrimental effect on concurrent task performance, e.g., decreased accuracy, its effect on executive functions is poorly studied. Yet, the latter question is relevant to many real-world situations, e.g., rapid stopping during driving. Here we studied how mind-wandering would affect the requirement to subsequently stop an incipient motor response. We tested, first, whether mind-wandering affected stopping, and second, which component of stopping was affected: the triggering of the inhibitory brake or the implementation of the brake following triggering. We observed that during mind-wandering, stopping-latency increased as did the proportion of trials with failed triggering. Indeed, 67% of the variance of the increase in stopping-latency was explained by the increased trigger failures. Thus, mind-wandering affects stopping, primarily by affecting the triggering of the brake.

Psychomotor Vigilance

Background: The current study examined people’s propensity to mind wander when they perform vigilance tasks that tap different components of vigilance, namely arousal or executive. We suggest that the propensity to mind-wander may occur not only spontaneously (unintentional), but also deliberately (intentional) and that this distinction may have considerable theoretical implications. Thus, while intentional mind-wandering could arise from a lack of motivation and monotonicity of the task, unintentional mind-wandering could be driven mainly by a failure of executive control. Methods: Participants performed the Psychomotor Vigilance Task (PVT) to assess the arousal component of vigilance, and the Sustained Attention to Response task (SART) to assess the executive component of vigilance. Two types of mind wandering were probed throughout the task execution, intentional and unintentional. Results: The rates of overall mind-wandering were greater for the PVT than for the SART. Although there was greater propensity to develop unintentional than intentional mind-wandering in both tasks, propensity to intentional mind-wandering was higher with the PVT than with the SART, whereas the ratio of unintentional mind-wandering was higher with the SART than with the PVT. Finally, regarding unintentional mind wandering, in the PVT, the most pronounced increment occurred between blocks 1 and 2, and thereafter it stabilized. In the SART, a rather progressive increment was observed as the task progressed. Regarding intentional mind wandering, progressive increment was observed mainly in the SART.Conclusions: The differential patterns of intentional and unintentional mind wandering as a function of task suggest that, intentional mind wandering occurs mainly in monotonous tasks where propensity to mind wander has little impact on task performance. However, unintentional mind wandering is the result of a failure to keep control on the primary executive task and therefore attentional resources deviate to mind wander, the default mode. These results support and extend the Thompson et al.’s (2015) resource-control model.

An operational definition of mind wandering is when one has thoughts unrelated to the current task(s) (Smallwood & Schooler, 2015). Mind blanking can be thought of as a subtype of mind wandering where there is an inability to report the content of these task-unrelated thoughts. Van den Driessche et al. (2017) found that children and young adults with more Attention-Deficit/Hyperactivity Disorder (ADHD) symptoms report more mind blanking than those with fewer ADHD symptoms and that non-medicated children with ADHD reported less mind wandering and more mind blanking than medicated children with ADHD. Van den Driessche et al. speculated that medication facilitated executive control and that executive resources support mind wandering (and on-task thought). These findings also bear on the theoretical debate on the role of executive functions in conscious experience. Some argue that executive functions support mind wandering (Levinson et al., 2012; Smallwood, 2010), while others argue and that mind wandering situationally results from a lack (or failure) of executive control (McVay & Kane, 2010; Meier, 2019). In this study, with a young adult sample, I tested the association between ADHD symptomology and conscious experience and if executive resources moderate the proportion of reporting mind blanking and mind wandering. The current study found evidence for Van den Driessche et al.’s finding of a positive and significant association between mind blanking and ADHD symptomology. The current study was also broadly consistent with Van den Driessche et al.’s finding of an ADHD-related trade-off involving mind blanking, but importantly differs from Van den Driessche et al. in that mind wandering was not involved in this trade-off. The current study did not find an association between working memory capacity and mind wandering. Thus, I found no evidence for executive resources supporting mind wandering, consistent with previous studies (McVay & Kane, 2009, 2012a, 2012b; Meier, 2019; Robison & Unsworth, 2018; Unsworth & McMillan, 2013, 2014).

Van den Driessche et al. (2017) found that children and young adults with more Attention Deficit Hyperactivity Disorder (ADHD) symptoms report more mind blanking than those with fewer ADHD symptoms and that non-medicated children with ADHD reported less mind wandering and more mind blanking than medicated children with ADHD. Van den Driessche et al. speculated that medication facilitated executive control and that executive resources support mind wandering (and on-task thought). Besides describing the conscious experience of those with ADHD symptomology, these findings bear on the theoretical debate of executive functions’ role in conscious experience. Some argue that executive functions support mind wandering (Levinson, Smallwood, & Davidson, 2012; Smallwood, 2010, 2013), while others argue that mind wandering situationally results from a lack (or failure) of executive control (McVay & Kane, 2010; Meier, 2019). Here, we conducted a study like Van den Driessche et al.’s study with young adults (Experiment 2, 2017) and tested the associations between ADHD symptomology and conscious experience. Rather than speculating about the effects of medication, we directly measured executive functioning (via complex span tasks). Like Van den Driessche et al., we observed a positive association between mind blanking and ADHD, but we detected no evidence supporting the claim that executive functions support mind wandering. We also assessed the relative associations between task performance metrics and reports of mind blanking and mind wandering. We did not detect differential performance associations between those thought reports.

Underlying Mechanisms

Over the last decade, implicit measures of mental associations (e.g., Implicit Association Test, sequential priming) have become increasingly popular in many areas of psychological research. Even though successful applications provide preliminary support for the validity of these measures, their underlying mechanisms are still controversial. The present article addresses the role of a particular mechanism that is hypothesized to mediate the influence of activated associations on task performance in many implicit measures: response interference (RI). Based on a review of relevant evidence, we argue that RI effects in implicit measures depend on participants’ attention to association-relevant stimulus features, which in turn can influence the reliability and the construct validity of these measures. Drawing on a moderated-mediation model (MMM) of task performance in RI paradigms, we provide several suggestions on how to address these problems in research using implicit measures.

Abstract. Fighter pilots may be exposed to extended flight missions. Consequently, there is increasing concern about fatigue. We investigated the effects of fatigue and cognitive performance in a simulated 11-hr mission in the 39 Gripen fighter aircraft. Five cognitive tasks were used to assess cognitive performance. Fatigue was measured with the Samn–Perelli Fatigue Index. Results showed that performance in the non-executive task degraded after approximately 7 hr. Fatigue ratings showed a matching trend to the performance in this task. Performance in tasks taxing executive functions did not decline. We interpreted that fatigue can be overridden by increased attentional effort for executive tasks but not for non-executive components of cognition. Participants underestimated their performance and metacognitive accuracy was not influenced by fatigue.

Selection Of

Selective attention is a fundamental cognitive function that guides behavior by selecting and prioritizing salient or relevant sensory information of our environment. Despite early evidence and theoretical proposal pointing to an implication of thalamic control in attention, most studies in the past two decades focused on cortical substrates, largely ignoring the contribution of subcortical regions as well as cortico-subcortical interactions. Here, we suggest a key role of the pulvinar in the selection of salient and relevant information via its involvement in priority maps computation. Prioritization may be achieved through a pulvinar- mediated generation of alpha oscillations, which may then modulate neuronal gain in thalamo-cortical circuits. Such mechanism might orchestrate the synchrony of cortico-cortical interaction, by rendering neural communication more effective, precise and selective. We propose that this theoretical framework will support a timely shift from the prevailing cortico- centric view of cognition to a more integrative perspective of thalamic contributions to attention and executive control processes.
