The brief mind wandering three-factor scale (BMW-3).

In recent years, researchers from different fields have become increasingly interested in measuring individual differences in mind wandering as a psychological trait. Although there are several questionnaires that allow for an assessment of people's perceptions of their mind wandering experiences, they either define mind wandering in a very broad sense or do not sufficiently separate different aspects of mind wandering. Here, we introduce the Brief Mind Wandering Three-Factor Scale (BMW-3), a 12-item questionnaire available in German and English.

Individual differences in working memory capacity and temporal preparation: A secondary reanalysis.

The ability to prepare and maintain an optimal level of preparedness for action, across some unknown duration, is critical for human behavior. Temporal preparation has historically been analyzed in the context of reaction time (RT) experiments where the interval varies between the start of the trial, or foreperiod (FP), and the required response. Two main findings have come out of such paradigms: the variable FP effect (longer RTs to shorter vs.

Mind-wandering in daily life in depressed individuals: An experience sampling study.

Background: A diagnostic criterion for Major Depressive Disorder (MDD) is difficulty concentrating and increased distractibility. One form of distraction that occurs in everyday life is mind-wandering. The current study aims to test how individuals with MDD and healthy controls differ in their mind-wandering in everyday life.

Cross-sectional and longitudinal changes in mind-wandering in older adulthood.

Age-related declines in the frequency of mind-wandering are well established. Theories of mind-wandering have attempted to explain why this decline occurs, but no one theory firmly predicts such changes. One problem with these theoretical views, and the studies that have grown out of them, is their reliance on cross-sectional methods, which do not account for within-person changes over time in mind-wandering, and it is well-documented that cross-sectional and longitudinal changes in some cognitive domains do not align.

Effects of emotional valence of mind wandering on sustained attention performance.

The construct of mind wandering has notoriously been characterized as heterogenous which may mean that not all types of mind wandering produce the same pattern of results. One operationalization of mind wandering, task-unrelated thoughts (TUTs), can also itself vary in many dimensions, including the emotional valence of TUTs. The current study summarizes several years of work examining the impact that the emotional valence of TUTs has on different aspects of sustained attention.

Positively framing mind wandering does not increase mind wandering in older adults.

Age-related differences in mind wandering are robust, with older adults reporting less mind wandering compared to younger adults. While several theories have been put forth to explain this difference, one view has received less attention than others. Specifically, age-related differences in mind wandering might occur because older adults are reluctant to report on their mind wandering.

Further unpacking individual differences in mind wandering: The role of emotional valence and awareness.

Previous work has established a link between executive attention ability and mind wandering propensity, these studies typically collapse thought reports into a single category of task-unrelated thoughts (TUTs). We have shown that these TUTs can be differentiated by the emotional valence of their content. Awareness of TUTs might also be an important to consider, yet little work has been done on this front.

Antecedents of mind wandering states in healthy aging and mild cognitive impairment.

Objective: Mind wandering refers to periods of internally directed attention and comprises up to 30% or more of our waking thoughts. Frequent mind wandering can be detrimental to ongoing task performance. We aim to determine whether rates of mind wandering change in healthy aging and mild cognitive impairment and how differences in mind wandering contribute to differences in attention and working memory.

Naturalistic assessment of reaction time variability in older adults at risk for Alzheimer's disease.

Objective: Maintaining attention underlies many aspects of cognition and becomes compromised early in neurodegenerative diseases like Alzheimer's disease (AD). The consistency of maintaining attention can be measured with reaction time (RT) variability. Previous work has focused on measuring such fluctuations during in-clinic testing, but recent developments in remote, smartphone-based cognitive assessments can allow one to test if these fluctuations in attention are evident in naturalistic settings and if they are sensitive to traditional clinical and cognitive markers of AD.

A combined experimental-correlational approach to the construct validity of performance-based and self-report-based measures of sustained attention.

The ability to sustain attention is often measured with either objective performance indicators, like within-person RT variability, or subjective self-reports, like mind wandering propensity. A more construct valid approach, however, may be to assess the covariation in these performance and self-report measures, given that each of these is influenced by different sources of measurement error. If the correlation between performance-variability and self-report measures reflects the sustained attention construct, then task manipulations aimed at reducing the sustained attention demands of tasks should reduce the correlation between them (in addition to reducing mean levels of variability and mind wandering).

Age-Related Differences in Mind Wandering: The Role of Emotional Valence.

Objectives: Older adults consistently report fewer experiences of mind wandering compared to younger adults. Aging is also associated with a shift in the emotional focus of our thoughts, with older adults tending to experience an increase in attention toward positive information, or a "positivity bias," relative to younger adults. Here, we tested if the positivity bias associated with aging can also predict age-related changes in the content of older adults' mind wandering.

A Nomothetic Span Approach to the Construct Validation of Sustained Attention Consistency: Re-Analyzing Two Latent-Variable Studies of Performance Variability and Mind-Wandering Self-Reports.

The ability to sustain attention consistency is frequently assessed using either objective behavioral measures, such as reaction time (RT) variability, or subjective self-report measures, such as rates of task-unrelated thought (TUT). The current studies examined whether the individual-difference covariation in these measures provides a more construct valid assessment of attention consistency than does either alone. We argue that performance and self-report measures mutually validate each other; each measurement approach has its own sources of error, so their shared variance should best reflect the attention consistency construct.

A "Goldilocks zone" for mind-wandering reports? A secondary data analysis of how few thought probes are enough for reliable and valid measurement.

Mind-wandering assessment relies heavily on the thought probe technique as a reliable and valid method to assess momentary task-unrelated thought (TUT), but there is little guidance available to help researchers decide how many probes to include within a task. Too few probes may lead to unreliable measurement, but too many probes might artificially disrupt normal thought flow and produce reactive effects. Is there a "Goldilocks zone" for how few thought probes can be used to reliably and validly assess individual differences in mind-wandering propensity? We address this question by reanalyzing two published datasets (Study 1, n = 541; Study 2, ns ≈ 260 per condition) in which thought probes were presented in multiple tasks.

Interpolated testing and content pretesting as interventions to reduce task-unrelated thoughts during a video lecture.

Considerable research has examined the prevalence and apparent consequences of task-unrelated thoughts (TUTs) in both laboratory and authentic educational settings. Few studies, however, have explored methods to reduce TUTs during learning; those few studies tested small samples or used unvalidated TUT assessments. The present experimental study attempted to conceptually replicate or extend previous findings of interpolated testing and pretesting effects on TUT and learning.

Individual differences in dimensions of mind wandering: the mediating role of emotional valence and intentionality.

Individual differences in executive control ability reliably show that those with greater executive control report fewer instances of mind wandering during moderately demanding tasks. However, these findings have been limited in that they often treated mind wandering as a variable that collapsed across a variety of thought categories or dimensions. We suggest that two dimensions of mind wandering, intentionality and emotional valence, may be differential related to individual difference in executive control ability.

Linking the dynamics of cognitive control to individual differences in working memory capacity: Evidence from reaching behavior.

We used a technique known as reach tracking to investigate how individual differences in working memory capacity (WMC) relate to the functioning of two processes proposed to underlie cognitive control: a threshold adjustment process that temporarily inhibits motor output in response to signals of conflict and a controlled selection process that recruits top-down control to guide stimulus-response translation. Undergraduates (N = 135) performed two WMC tasks (updating counters and symmetry span) and a reach-tracking version of the Eriksen flanker task. Consistent with previous research using button-press flanker tasks, WMC significantly correlated with response time (RT) performance, with higher WMC scores corresponding to smaller congruency effects.

Testing the construct validity of competing measurement approaches to probed mind-wandering reports.

Psychology faces a measurement crisis, and mind-wandering research is not immune. The present study explored the construct validity of probed mind-wandering reports (i.e.

The Worst Performance Rule, or the Not-Best Performance Rule? Latent-Variable Analyses of Working Memory Capacity, Mind-Wandering Propensity, and Reaction Time.

The worst performance rule (WPR) is a robust empirical finding reflecting that people's worst task performance shows numerically stronger correlations with cognitive ability than their average or best performance. However, recent meta-analytic work has proposed this be renamed the "not-best performance" rule because mean and worst performance seem to predict cognitive ability to similar degrees, with both predicting ability better than best performance. We re-analyzed data from a previously published latent-variable study to test for worst vs.

Examining the role of emotional valence of mind wandering: All mind wandering is not equal.

To evaluate the role of emotional valence on the impact of mind wandering on working memory (WM) and sustained attention, we reanalyzed data from three independently conducted studies that examined the impact of stress on WM (Banks & Boals, 2016; Banks, Welhaf, & Srour, 2015) and sustained attention (Banks, Tartar, & Welhaf, 2014). Across all studies, participants reported the content of their thoughts at random intervals during the WM or sustained attention task. Thought probes in all studies included a core set of response options for task-unrelated thoughts (TUTs) that were negatively, positively, or neutrally emotionally valenced.

The protective effects of brief mindfulness meditation training.

Mindfulness meditation has gained a great deal of attention in recent years due to the variety of physical and psychological benefits, including improved working memory, decreased mind wandering and reduced impact of stress on working memory. The current study examined a 1-week at home mindfulness meditation intervention compared to an active control intervention. Results suggest that mindfulness meditation does not increase working memory or decrease mind wandering but does prevent stress related working memory impairments.

Where's the impairment: an examination of factors that impact sustained attention following a stressor.

The impact of stress on cognitive functioning has been examined across multiple domains. However, few studies investigate both physical and psychological factors that impact cognitive performance. The current study examined the impact of a physical and psychosocial stressor on sustained attention and identified factors related to sustained attention, including cortisol, salivary alpha amylase (sAA) and mind wandering.
