Individual differences and state effects on mind-wandering: Hypnotizability, dissociation, and sensory homogenization
Publication year: 2012

http://www.sciencedirect.com/science/article/pii/S1053810012000748
Abstract/Results: ABSTRACT:
Consciousness alterations can be experienced during unstructured, monotonous stimuli. These effects have not been linked to particular cognitive operations; individual differences in response to such stimulation remain poorly understood. We examined the role of hypnotizability and dissociative tendencies in mind-wandering (MW) during a sensory homogenization procedure (ganzfeld). We expected that the influence of ganzfeld on MW would be more pronounced among highly hypnotizable individuals (highs), particularly those high in dissociative tendencies. High and low hypnotizables, also stratified by dissociation, completed the sustained attention to response task during ganzfeld and control conditions. High dissociative highs made more commission errors during ganzfeld, suggesting increased MW, whereas the other groups displayed the opposite pattern. Increases in commission errors from the control condition to ganzfeld were associated with more alterations in consciousness and negative affect, but only among highs. Sensory
homogenization had opposite effects onMWdepending on the interaction of hypnotizability and dissociation.

Transcranial direct current stimulation of the medial prefrontal cortex dampens mind-wandering in men
Publication year: 2017
URL:
https://www.nature.com/articles/s41598-017-17267-4
Abstract/Results: ABSTRACT:
Mind-wandering, the mind’s capacity to stray from external events and generate task-unrelated thought, has been associated with activity in the brain default network. To date, little is understood about the contribution of individual nodes of this network to mind-wandering. Here, we investigated the role of medial prefrontal cortex (mPFC) in mind-wandering, by perturbing this region with transcranial direct current stimulation (tDCS). Young healthy participants performed a choice reaction time task both before and after receiving cathodal tDCS over mPFC, and had their thoughts periodically sampled. We found that tDCS over mPFC - but not occipital or sham tDCS - decreased the propensity to mind-wander. The tDCS-induced reduction in mind-wandering occurred in men, but not in women, and was accompanied by a change in the content of task-unrelated though, which became more related to other people (as opposed to the self) following tDCS. These findings indicate that mPFC is crucial for mind-wandering, possibly by helping construction of self-relevant scenarios capable to divert attention inward, away from perceptual reality. Gender-related differences in tDCS-induced changes suggest that mPFC controls mind-wandering differently in men and women, which may depend on differences in the structural and functional organization of distributed brain networks governing mind-wandering, including mPFC.

Insight from the consideration of REM dreams, non-REM dreams, and daydreams
Publication year: 2019

https://psycnet.apa.org/record/2018-64659-001
Abstract/Results: ABSTRACT:
Throughout history there have been reports and claims that consideration of dreams can produce personal realizations and insight. We assessed Exploration-Insight scores associated with discussing Rapid Eye Movement (REM) and non-REM (NREM) dreams in connection with recent waking life experiences. Thirty-one participants were cued in the sleep laboratory for a daydream report and then awakened from REM and N2 sleep for dream reports. Participants subsequently discussed each of their dream and daydream reports for 30-40 minutes with two experimenters, following the structured Ullman (1996) dream group discussion procedure. Participants assessed the benefit of discussing the reports by completing the Gains from (Day)Dream Interpretation (G(D)DI) questionnaire. We found no difference in G(D)DI scores between discussing REM and N2 dream reports, and no difference between dream and daydream discussions in engagement and thoroughness of exploring the reports. However, discussing dream reports produced higher scores on the G(D)DI Exploration-Insight subscale compared with discussing daydream reports. Significant differences were evident in items reflecting the learning of what the report means in terms of waking life issues. Frontal theta prior to waking from N2 was significantly associated with Exploration-Insight score obtained after N2 dream discussion, but this relationship was not found for REM dreams. The findings of high ratings of Exploration-Insight after discussing dreams were evident even though participants did not select the dream, unlike what can occur for home recorded dreams, and even though discussion was brief. We suggest that insight might be produced by embodied and metaphorical thinking in dreams.

Meditation experience and mindfulness are associated with reduced self-reported mind-wandering in meditators — A German version of the daydreaming frequency scale
Publication year: 2019
URL:
https://www.mdpi.com/2624-8611/1/1/14
Abstract/Results: ABSTRACT
Mind-wandering or daydreaming can be described as spontaneous thoughts that are independent of the task at hand and the current sensory information. Mindfulness, defined as the ability to focus on the present moment with an accepting attitude towards the present experience, is considered to be the opposite of mind-wandering. We aimed at assessing how long-term meditation practice influences mind-wandering in everyday life and to which extent mind-wandering and self-reported aspects of mindfulness are conceptually linked. We first investigated the factorial structure of a German version of the Daydreaming Frequency Scale (DDFS) in a student population. Then we applied this version in meditators to a) investigate the relationship between meditation experience and reported levels of mind-wandering in daily life and b) explore how different facets of mindfulness, assessed with the Freiburg Mindfulness Inventory (FMI), relate to mind-wandering. Using a correlational design, we show that, among meditators, more meditation practice in years accounts for less self-reported mind-wandering in daily life. There was a negative association between mindfulness (FMI) and mind-wandering (DDFS). Our results provide evidence for clarifying the relationship between, meditation experience, mindfulness and mind-wandering and further validate the use of the FMI as a sensitive tool for assessing a two-factor structure of mindfulness.

Title:
Meditation experience and mindfulness are associated with reduced self-reported mind-wandering in meditators — A German version of the daydreaming frequency scale
Publication year: 2019

Abstract/Results: ABSTRACT
Mind-wandering or daydreaming can be described as spontaneous thoughts that are independent of the task at hand and the current sensory information. Mindfulness, defined as the ability to focus on the present moment with an accepting attitude towards the present experience, is considered to be the opposite of mind-wandering. We aimed at assessing how long-term meditation practice influences mind-wandering in everyday life and to which extent mind-wandering and self-reported aspects of mindfulness are conceptually linked. We first investigated the factorial structure of a German version of the Daydreaming Frequency Scale (DDFS) in a student population. Then we applied this version in meditators to a) investigate the relationship between meditation experience and reported levels of mind-wandering in daily life and b) explore how different facets of mindfulness, assessed with the Freiburg Mindfulness Inventory (FMI), relate to mind-wandering. Using a correlational design, we show that, among meditators, more meditation practice in years accounts for less self-reported mind-wandering in daily life. There was a negative association between mindfulness (FMI) and mind-wandering (DDFS). Our results provide evidence for clarifying the relationship between, meditation experience, mindfulness and mind-wandering and further validate the use of the FMI as a sensitive tool for assessing a two-factor structure of mindfulness.

Episodic thought distinguishes spontaneous cognition in waking from REM and NREM sleep
Publication year: 2021

Abstract/Results: ABSTRACT:
Evidence suggests continuity between cognition in waking and sleeping states. However, one type of cognition that may differ is episodic thoughts of the past and future. The current study investigated this across waking, NREM sleep and REM sleep. We analyzed thought reports obtained from a large sample of individuals (N = 138) who underwent experience-sampling during wakefulness as well as serial awakenings in sleep. Our data suggest that while episodic thoughts are common during waking spontaneous thought, episodic thoughts of both the past and the future rarely occur in either N2 or REM sleep. Moreover, replicating previous findings, episodic thoughts during wakefulness exhibit a strong prospective bias and frequently involve autobiographical planning. Together, these results suggest that the occurrence of spontaneous episodic thoughts differs substantially across waking and dreaming sleep states. We suggest that this points to a difference in the way that human consciousness is typically experienced across the sleep-wake cycle.

Evaluating brain spectral and connectivity differences between silent mind-wandering and trance states
Publication year: 2023

Abstract/Results: ABSTRACT:
Trance is an altered state of consciousness characterized by alterations in cognition. In general, trance states induce mental silence (i.e., cognitive thought reduction), and mental silence can induce trance states. Conversely, mind-wandering is the mind's propensity to stray its attention away from the task at hand and toward content irrelevant to the current moment, and its main component is inner speech. Building on the previous literature on mental silence and trance states and incorporating inverse source reconstruction advances, the study's objectives were to evaluate differences between trance and mind-wandering states using: (1) electroencephalography (EEG) power spectra at the electrode level, (2) power spectra at the area level (source reconstructed signal), and (3) EEG functional connectivity between these areas (i.e., how they interact). The relationship between subjective trance depths ratings and whole-brain connectivity during trance was also evaluated. Spectral analyses revealed increased delta and theta power in the frontal region and increased gamma in the centro-parietal region during mind-wandering, whereas trance showed increased beta and gamma power in the frontal region. Power spectra at the area level and pairwise comparisons of the connectivity between these areas demonstrated no significant difference between the two states. However, subjective trance depth ratings were inversely correlated with whole-brain connectivity in all frequency bands (i.e., deeper trance is associated with less large-scale connectivity). Trance allows one to enter mentally silent states and explore their neurophenomenological processes. Limitations and future directions are discussed.

Abstract/Results: ABSTRACT:
EEG microstates, reflecting discrete topographical organization of the EEG signal power, may have clinical relevance; however, their functional significance and test-retest reliability remain unclear. To investigate the functional significance of the canonical EEG microstate classes and their pairwise transitions, and to establish their within-session test-retest reliability, we recorded 36-channel EEGs in 20 healthy volunteers during three eyes-closed conditions: mind-wandering, verbalization (silently repeating the word ‘square’ every 2 s), and visualization (visualizing a square every 2 s). Each condition lasted 3 min and the sequence of three conditions was repeated four times (two runs of two sequence repetitions). The participants' alertness and their sense of effort during the experiment were rated using visual-analogue scales. The EEG data were 2–20 Hz bandpass-filtered and analysed into the four canonical microstate classes: A, B, C, and D. EEG microstate classes C and D were persistently more dominant than classes A and B in all conditions. Of the first-order microstate parameters, average microstate duration was most reliable. The duration of class D microstate was longer during mind-wandering (106.8 ms) than verbalization (102.2 ms) or visualization (99.8 ms), with a concomitantly higher coverage (36.4% vs. 34.7% and 35.2%), but otherwise there was no clear association of the four microstate classes to particular mental states. The test-retest reliability was higher at the beginning of each run, together with higher average alpha power and subjective ratings of alertness. Only the transitions between classes C and D (from C to D in particular) were significantly higher than what would be expected from the respective microstates' occurrences. The transition probabilities, however, did not distinguish between conditions, and their test-retest reliability was overall lower than that of the first-order parameters such as duration and coverage. Further studies are needed to establish the functional significance of the canonical EEG microstate classes. This might be more fruitfully achieved by looking at their complex syntax beyond pairwise transitions. To ensure greater test-retest reliability of microstate parameters, study designs should allow for shorter experimental runs with regular breaks, particularly when using EEG microstates as clinical biomarkers.
