Level of construal, mind wandering, and repetitive thought: Reply to McVay and Kane (2010).

In this reply to the comment of McVay and Kane (2010), I consider their argument concerning how Watkins’s (2008) elaborated control theory informs their perspective on the role of executive control in mind wandering. I argue that although in a number of places the elaborated control theory is consistent with the perspective of McVay and Kane that mind wandering represents a failure of executive control, their account makes a number of claims that are not articulated in the elaborated control theory—most notably, the hypothesis that level of construal moderates entry of thoughts into awareness. Moreover, the relevant literature suggests that the relationship between level of construal and executive control may be more complex, and may be determined by multiple factors beyond those proposed in this executive-control failure account of mind wandering. Finally, the implications of this model of mind wandering for understanding repetitive thought in general are considered, and it is proposed that examining level of executive control as a further moderating variable within elaborated control theory may be of value.

Spontaneous repetitive thoughts can be adaptive: Postscript on “mind wandering”.

When researchers use the term mind wandering for task-unrelated thoughts in signal detection tasks, we may fall into the trap of believing that spontaneous thoughts are task unrelated in a deeper sense. Similar negative connotations are attached to common terms like cognitive failures, resting state, rumination, distraction, attentional failures, absent-mindedness, repetitiveness, mind lapses, going AWOL in the brain, cortical idling, and the like. Nevertheless, it seems obvious that mathematicians and scientists often engage in spontaneous repetitive thoughts and that the results of those thoughts are by no means maladaptive. Yet that seems to be implied by the standard use of common terms in the research literature. As humans, we know that spontaneous ideation goes on during all of our waking hours, during dreams and even in slow-wave sleep. It is unlikely that such a great allocation of mental resources has no useful adaptive function. This view of the spontaneous stream is consistent with the perspective of global workspace theory on conscious contents, which suggests that conscious events are not like unconscious cognitive representations. Rather, conscious events trigger widespread adaptive changes in the brain, far beyond their cortical origins. The brain evidence for such “global broadcasting” triggered by conscious (but not matched unconscious) events throughout the cortex is now quite compelling. Spontaneous conscious thoughts, even if they appear to be arbitrary, irrelevant, unwanted, or intrusive, may still play an important adaptive role in life-relevant problem solving and learning.

Does mind wandering reflect executive function or executive failure? Comment on Smallwood and Schooler (2006) and Watkins (2008).

In this comment, we contrast different conceptions of mind wandering that were presented in 2 recent theoretical reviews: Smallwood and Schooler (2006) and Watkins (2008). We also introduce a new perspective on the role of executive control in mind wandering by integrating empirical evidence presented in Smallwood and Schooler with 2 theoretical frameworks: Watkins’s elaborated control theory and Klinger’s (1971, 2009) current concerns theory. In contrast to the Smallwood–Schooler claim that mind wandering recruits executive resources, we argue that mind wandering represents a failure of executive control and that it is dually determined by the presence of automatically generated thoughts in response to environmental and mental cues and the ability of the executive-control system to deal with this interference. We present empirical support for this view from experimental, neuroimaging, and individual-differences research. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The restless mind.

This article reviews the hypothesis that mind wandering can be integrated into executive models of attention. Evidence suggests that mind wandering shares many similarities with traditional notions of executive control. When mind wandering occurs, the executive components of attention appear to shift away from the primary task, leading to failures in task performance and superficial representations of the external environment. One challenge for incorporating mind wandering into standard executive models is that it often occurs in the absence of explicit intention--a hallmark of controlled processing. However, mind wandering, like other goal-related processes, can be engaged without explicit awareness; thus, mind wandering can be seen as a goal-driven process, albeit one that is not directed toward the primary task.

Shifting moods, wandering minds: Negative moods lead the mind to wander.

This study examined the effect of mood states on mind wandering. Positive, neutral, and negative moods were induced in participants prior to them completing a sustained attention task. Mind wandering was measured by using the frequencies of both behavioral lapses and retrospective indices of subjective experience. Relative to a positive mood, induction of a negative mood led participants to make more lapses, report a greater frequency of task irrelevant thoughts, and become less inclined to reengage attentional resources following a lapse. Positive mood, by contrast, was associated with a better ability to adjust performance after a lapse. These results provide further support for the notion that a negative mood reduces the amount of attentional commitment to the task in hand and may do so by enhancing the focus on task irrelevant personal concerns.

Conducting the train of thought: Working memory capacity, goal neglect, and mind wandering in an executive-control task.

On the basis of the executive-attention theory of working memory capacity (WMC; e.g., M. J. Kane, A. R. A. Conway, D. Z. Hambrick, & R. W. Engle, 2007), the authors tested the relations among WMC, mind wandering, and goal neglect in a sustained attention to response task (SART; a go/no-go task). In 3 SART versions, making conceptual versus perceptual processing demands, subjects periodically indicated their thought content when probed following rare no-go targets. SART processing demands did not affect mind-wandering rates, but mind-wandering rates varied with WMC and predicted goal-neglect errors in the task; furthermore, mind-wandering rates partially mediated the WMC-SART relation, indicating that WMC-related differences in goal neglect were due, in part, to variation in the control of conscious thought.

Task-unrelated thought frequency as a function of age: A laboratory study.

Using retrospective reports, Giambra (1977–1978, 1979–1980) found an inverse relation between age and daydreaming/mind wandering. To deal with an alternate explanation of these results based on age-dependent memorial deficiencies and attitudes toward daydreaming/mind wandering and to provide independent convergent validity, five experiments were carried out. Task-unrelated thoughts (TUTs) were taken as the operational definition of daydreams/mind wanderings and their frequency recorded in vigilance tasks. All five experiments found an inverse relation between age (17–92 years, N?=?471) and TUTs, confirming the reliability and validity of the earlier studies. The age-dependent reduction in TUTs was considered as evidence of reduced nonconscious information processing with increased age. The results of this study were incompatible with a recent theory that predicts for older individuals an increased input of irrelevant thoughts into working memory due to the older individual's reduced inhibitory control.

Consciousness and the voices of the mind.

Few problems have had as interesting an intellectual trajectory through history as that of the mind and its place in nature. Before 1859, the year that Darwin and Wallace independently proposed natural selection as the basis of evolution, this issue was known as the mind/body problem with its various and sometimes ponderous solutions. But after that pivotal date, it came to be known as the problem of consciousness and its origin in evolution. Now the first thing I wish to stress this afternoon is this problem. It is easy for the average layman to understand. But paradoxically, for philosophers, psychologists, and neurophysiologists, who have been so used to a different kind of thinking, it is a difficult thing. What we have to explain is the contrast, so obvious to a child, between all the inner covert world of imaginings and memories and thoughts and the external public world around us. The theory of evolution beautifully explains the anatomy of species, but how out of mere matter, mere molecules, mutations, anatomies, can you get this rich inner experience that is always accompanying us during the day and in our dreams at night? That is the problem we will consider in this symposium. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relation between rumination and impaired memory in dysphoric moods.

College students in dysphoric or nondysphoric moods studied pairs of words and later took a fragment-completion test of memory for targets from the pairs (under process-dissociation procedures for obtaining estimates of controlled and automatic retrieval; L. L. Jacoby, 1996). Between the study and test phases, some participants waited quietly for 7 min; others rated self-focused materials designed to invoke ruminations in the dysphoric group; and still others rated self-irrelevant and task-irrelevant materials. A dysphoria-related impairment in controlled retrieval occurred in the first 2 conditions but not in the 3rd condition. These results show that the nature of task-irrelevant thoughts contributes to memory impairments in dysphoria and suggest that self-focused rumination might also contribute to similar impairments under unconstrained conditions that permit mind wandering.

Working memory capacity and the top-down control of visual search: Exploring the boundaries of "executive attention".

The executive attention theory of working memory capacity (WMC) proposes that measures of WMC broadly predict higher order cognitive abilities because they tap important and general attention capabilities (R. W. Engle & M. J. Kane, 2004). Previous research demonstrated WMC-related differences in attention tasks that required restraint of habitual responses or constraint of conscious focus. To further specify the executive attention construct, the present experiments sought boundary conditions of the WMC-attention relation. Three experiments correlated individual differences in WMC, as measured by complex span tasks, and executive control of visual search. In feature-absence search, conjunction search, and spatial configuration search, WMC was unrelated to search slopes, although they were large and reliably measured. Even in a search task designed to require the volitional movement of attention (J. M. Wolfe, G. A. Alvarez, & T. S. Horowitz, 2000), WMC was irrelevant to performance. Thus, WMC is not associated with all demanding or controlled attention processes, which poses problems for some general theories of WMC.

On Attneave's tridimensional cognitive workspace.

Comments on F. Attneave's (see record 1975-00003-001) suggestions about a tridimensional mental workspace of knowing. The robustness and flexibility of the mind and its sensitivity to change permit a proposed workspace of n dimensions: 3 or 4 for typical space–time events, more for more complicated events (e.g., orchestration).

Action selection in complex routinized sequential behaviors.

We report two experiments in which errors and interaction latencies were recorded during routinization of hierarchically structured computer-based tasks. Experiment 1 demonstrates that action selection is slowed at subtask transitions, especially when selecting lower frequency actions. This frequency effect is compounded by concurrent performance of a secondary, attentionally demanding, task. Experiment 2 replicates these results in a more complex task and further demonstrates that the effects are reduced by experience. Several other factors were also found to affect latencies, including the availability of an external disambiguation cue and the temporal distance over which task context needs to be internally maintained. The results support a “dual-systems” account of action selection in which a “routine” system, sensitive to frequency, context, and experience, is selectively modulated by an attentionally demanding “nonroutine” system.

Sense of coherence as a protective mechanism among targets of workplace bullying.

The present study investigated sense of coherence (SOC) as a protective factor among targets of workplace bullying. A hypothesis that strong SOC lessens the relationship between exposure to bullying and symptoms of posttraumatic stress was tested in a cross-sectional sample of 221 self-labeled targets of workplace bullying. The findings showed that SOC offers most protective benefits to targets exposed to low levels of bullying, whereas the benefits of SOC diminish as bullying becomes more severe. The results support previous findings that workplace bullying is a traumatic experience for those exposed to it, regardless of the target's available coping resources.

Why Hell is other people: Distinctively human psychological suffering.

Just as there is remarkable continuity between the structures, abilities, and behaviors of closely related species, so too are there equally remarkable differences. Because only our species has evolved the social cognitive mechanisms that enable a heightened sensitivity to the minds of others, only our species suffers the psychological consequences. Using Sartre's famous play No Exit to illuminate the interplay between evolved psychology and social conscious experience, I show how theory of mind is both biologically adaptive and the common denominator in distinctively human types of psychological suffering.

When perspective taking increases taking: Reactive egoism in social interaction.

Group members often reason egocentrically, believing that they deserve more than their fair share of group resources. Leading people to consider other members' thoughts and perspectives can reduce these egocentric (self-centered) judgments such that people claim that it is fair for them to take less; however, the consideration of others' thoughts and perspectives actually increases egoistic (selfish) behavior such that people actually take more of available resources. A series of experiments demonstrates this pattern in competitive contexts in which considering others' perspectives activates egoistic theories of their likely behavior, leading people to counter by behaving more egoistically themselves. This reactive egoism is attenuated in cooperative contexts. Discussion focuses on the implications of reactive egoism in social interaction and on strategies for alleviating its potentially deleterious effects.

Cancer and the threat of death: The cognitive dynamics of death-thought suppression and its impact on behavioral health intentions.

Five studies examined the cognitive association between thoughts of cancer and thoughts of death and their implication for screening intentions. Study 1 found that explicit contemplation of cancer did not increase death-thought accessibility. In support of the hypothesis that this reflects suppression of death-related thoughts, Study 2 found that individuals who thought about cancer exhibited elevated death-thought accessibility under high cognitive load, and Study 3 demonstrated that subliminal primes of the word cancer led to increased death-thought accessibility. Study 4 revealed lower levels of death-thought accessibility when perceived vulnerability to cancer was high, once again suggesting suppression of death-related thoughts in response to conscious threats associated with cancer. Study 5 extended the analysis by finding that after cancer salience, high cognitive load, which presumably disrupts suppression of the association between cancer and death, decreased cancer-related self-exam intentions. Theoretical and practical implications for understanding terror management, priming and suppression, and responses to cancer are discussed.

Pupillary responses index overload of working memory resources in schizophrenia.

The authors examined the hypothesis that schizophrenia patients have reduced availability of working memory resources by using pupillary responses as an index of resource overload. Pupillary responses were recorded during a verbal working memory task (digit recall) in 24 schizophrenia patients and 32 normal controls. Pupil size increased with increased processing load (digit-span length) but changed little or declined when processing demands exceeded available resources (overload). The schizophrenia patients showed impaired digit recall and abnormally small pupillary responses during digit presentation only in the higher processing load conditions, but they showed abnormally small pupillary responses during digit retrieval in all processing load conditions. The results suggest reduced availability of slave store and central executive working memory resources in schizophrenia. This study serves as an example of how pupillography methods can be used to test current hypotheses regarding overload of cognitive capacities in schizophrenia patients.

Section 3: Memory and higher-order cognition.

Introduces Section 3 of this issue of the Canadian Journal of Experimental Psychology, which focuses on memory and higher-order cognition. The central thought preoccupying our conscious experience can vary greatly from moment to moment. At one moment we are preoccupied with trying to remember where we left our keys; at another moment we are wondering why the traffic seems slower in our lane. Just as varied are the different approaches taken to studying how the brain enables the higher-order thinking that leads to these conscious experiences. This section highlights a sampling of those approaches; using event related potentials (ERPs) to study various elements of remembering the past, using functional magnetic resonance imaging (fMRI) to study anatomical differences between memory and decision making, using ERPs to study how we semantically integrate spatial reference frames, and comparing nonhuman primates to young children in order to study our drive to seek explanations. The intent of this section is to demonstrate the variety of techniques used to examine the relationship between the mind and the brain, and, more importantly, to demonstrate how the conscious experience is being explored in new and interesting ways.

Job Resources Buffer the Impact of Job Demands on Burnout.

This study tested and refined the job demands-resources model, demonstrating that several job resources play a role in buffering the impact of several job demands on burnout. A total of 1,012 employees of a large institute for higher education participated in the study. Four demanding aspects of the job (e.g., work overload, emotional demands) and 4 job resources (e.g., autonomy, performance feedback) were used to test the central hypothesis that the interaction between (high) demands and (low) resources produces the highest levels of burnout (exhaustion, cynicism, reduced professional efficacy). The hypothesis was rejected for (reduced) professional efficacy but confirmed for exhaustion and cynicism regarding 18 out of 32 possible 2-way interactions (i.e., combinations of specific job demands and resources).

The Hourglass Is Half Full or Half Empty: Temporal Framing and the Group Planning Fallacy.

Three studies tested hypotheses that temporal frames influence the group planning fallacy and are associated with subjective distance to deadlines and thoughts about successful task completion. Temporal framing effects occurred even though actual times to deadlines were held constant. In Study 1, groups predicted course project completion. Those adopting little time remaining frames exhibited less planning fallacy than those adopting lots of time remaining frames. Little time remaining frames were related to deadlines feeling closer and to fewer thoughts about success. Study 2 replicated this finding using a laboratory assembly task. Study 3 further indicated that it is whether thoughts about success come to mind easily, not thought content, that produces this effect; thoughts about success also led to deadlines feeling closer.
