The influence of app-based mindfulness training on the dorsolateral prefrontal cortex during an attentional control task: A fNIRS driven pilot study

Mindfulness-based interventions (MBIs) have been shown to be effective in treating psychological disturbances such as depression and anxiety. However the neural mechanisms underpinning MBIs, remain unclear. While studies employing functional magnetic resonance imaging (fMRI) and electroencephalography have advanced our understanding of neural correlates influenced by mindfulness, these modalities have notable limitations that restrict their applicability across various demographics. This study explored the feasibility of functional near-infrared spectroscopy (fNIRS) as a viable alternative for assessing neurocognitive changes induced by MBIs. To do this, fNIRS data was collected from 19 university students during a modified flanker task, before and after a week-long, app-based mindfulness intervention. Post intervention, participants improved their ability to inhibit pre-potent responses to stimuli after a rule change. While no significant pre-post changes in cortical activation of the DLPFC were observed, participants who performed better (i.e., better response accuracy) required less modulation from the DLPFC. These results continue to establish the use of fNIRS as an effective tool for understanding neurocognitive underpinnings of mindfulness. As a less invasive, cost-efficient modality, fNIRS shows promise in expanding neuroscientific investigation into understudied samples that may not be well suited for traditional methods such as fMRI. Ultimately, this could lead to more effective mindfulness interventions that have already shown promise in treating a range of physical and psychological disorders.

Comparing Self-Report vs. Performance Measures of Attentional Control and Efficiency

Background: The Attention Control Scale (ATTC) is a widely used self-report measure of attentional control capacities. However, research questions whether it accurately substitutes for objective attention control tasks. This study investigated ATTC’s correlation with the Attention Network Test (ANT) across alerting, orienting, and executive control networks. We also used the Inverse Efficiency Score (IES) as an additional factor to check ATTC using ANT. Methods: We administered 143 participants who completed the ATTC questionnaire and ANT behavioral test assessing network efficiencies. Results: The results showed non-significant ATTC-ANT correlations across all networks. In an additional analysis, while the ATTC demonstrated factorial validity, subjective control was disconnected from actual attention regulation efficiency. A small male advantage emerged for executive control. Conclusions: Dissociations likely stem from attention complexity and method variances rather than overlap. The findings do not support the ATTC as a stand-alone proxy for performance-based measurement. Multifaceted assessments are essential for comprehensively capturing attentional control.

Humans reconfigure target and distractor processing to address distinct task demands.

When faced with distraction, we can focus more on goal-relevant information (targets) or focus less on goal-conflicting information (distractors). How people use cognitive control to distribute attention across targets and distractors remains unclear. We address this question by developing a novel Parametric Attentional Control Task that can "tag" participants' sensitivity to target and distractor information. We use these precise measures of attention to develop a novel process model that can explain how participants control attention toward targets and distractors. Across three experiments, we find that participants met the demands of this task by independently controlling their processing of target and distractor information, exhibiting distinct adaptations to manipulations of incentives and conflict. Whereas incentives preferentially led to target enhancement, conflict in the previous trial preferentially led to distractor suppression. These distinct drivers of control altered sensitivity to targets and distractors early in the trial, promptly followed by reactive reconfiguration toward task-appropriate feature sensitivity. To provide a process-level account of these empirical findings, we develop a novel neural network model of evidence accumulation with attractor dynamics over feature weights that reconfigure target and distractor processing. These results provide a computational account of control reconfiguration that provides new insights into how multivariate attentional signals are optimized to achieve task goals.

Some young adults hyper-bind too: Attentional control relates to individual differences in hyper-binding.

Hyper-binding - the erroneous encoding of target and distractor information into associative pairs in memory - has been described as a unique age effect caused by declines in attentional control. Previous work has found that, on average, young adults do not hyper-bind. However, if hyper-binding is caused by reduced attentional control, then young adults with poor attention regulation should also show evidence of hyper-binding. We tested this question with an individual differences approach, using a battery of attentional control tasks and relating this to individual differences in hyper-binding. Participants (N = 121) completed an implicit associative memory test measuring memory for both target-distractor (i.e., hyper-binding) and target-target pairs, followed by a series of tasks measuring attentional control. Our results show that on average, young adults do not hyper-bind, but as predicted, those with poor attentional control show a larger hyper-binding effect than those with good attentional control. Exploratory analyses also suggest that individual differences in attentional control relate to susceptibility to interference at retrieval. These results support the hypothesis that hyper-binding in older adults is due to age-related declines in attentional control, and demonstrate that hyper-binding may be an issue for any individual with poor attentional control, regardless of age.

Individual differences in inattentional blindness.

People often fail to notice unexpected objects and events when they are performing an attention-demanding task, a phenomenon known as inattentional blindness. We might expect individual differences in cognitive ability or personality to predict who will and will not notice unexpected objects given that people vary in their ability to perform attention-demanding tasks. We conducted a comprehensive literature search for empirical inattentional blindness reports and identified 38 records that included individual difference measures and met our inclusion criteria. From those, we extracted individual difference effect sizes for 31 records which included a total of 74 distinct, between-groups samples with at least one codable individual difference measure. We conducted separate meta-analyses of the relationship between noticing/missing an unexpected object and scores on each of the 14 cognitive and 19 personality measures in this dataset. We also aggregated across personality measures reflecting positive/negative affectivity or openness/absorption and cognitive measures of interference, attention breadth, and memory. Collectively, these meta-analyses provided little evidence that individual differences in ability or personality predict noticing of an unexpected object. A robustness analysis that excluded samples with extremely low numbers of people who noticed or missed produced similar results. For most measures, the number of samples and the total sample sizes were small, and larger studies are needed to examine individual differences in inattentional blindness more systematically. However, the results are consistent with the idea that noticing of unexpected objects or events differs from deliberate attentional control tasks in that it is not reliably predicted by individual differences in cognitive ability.

Time to reflect on voice parades: The influence of reflection and retention interval duration on earwitness performance

AbstractExperiment‐based voice parades often result in low hit‐rates and high false‐alarm rates. One contributing factor may be that the experimental procedures omit elements that might naturally occur in the memory formation process, such as the process of reflection. In Experiment 1 (N = 180, F = 92) we explored if a post‐encoding reflection manipulation, compared to a simple attention control task, prior to a five‐minute retention interval would improve identification performance. In Experiment 2 (N = 180, F = 93), we explored how the effects of this manipulation might change when the retention interval was 24‐h. The results show that the inclusion of a reflection manipulation did not meaningfully improve performance in either experiment. Importantly, we found no meaningful difference in performance when directly comparing the two retention interval durations. We consider theoretical explanations for these results and discuss implications for the design and validity of earwitness voice parade studies.

The Cognitive Failures Questionnaire 2.0

Individual differences in the subjective experience of cognitive failures predict important outcomes, such as accident risk. Over the last four decades, these have been measured via the Cognitive Failures Questionnaire (CFQ). However, multiple CFQ items have diminished contemporary relevance and technology-related failures are not represented at all. Further, various attempts to identify multicomponent structures have had problems, which could be due to small numbers of items from which these structures are devised. Here we developed a large set of new items to more fully sample underlying psychological processes, including contemporary instances of cognitive failures, and performed an exploratory factor analysis (EFA) in a sample of adults (Study 1). This identified one dominant factor, which was supported by a subsequent confirmatory factor analysis (CFA) in Study 2. Study 3 replicated the CFA and demonstrated that scores explained variance in objective performance on an attentional control task beyond that explained by the original CFQ. Study 4 demonstrated that scores were associated with focusing, switching, cognitive empathy, affective empathy, and negative affect in ways consistent with the original CFQ. In Study 5, scores demonstrated good test-retest reliability. We offer this 15-item scale as a new and improved measure of cognitive failures (CFQ 2.0).

The construct of attention in studies in l2 phonology between 2010 and 2021

The acquisition of a second language (L2) is a highly demanding cognitive task that, in terms of phonology, happens through the siege of the first language (L1). The cue-weighting, that is, the attention given to specific cues in the L2 speech and the ability to change the focus of attention to relevant cues is essential for L2 speech processing and tends to be affected by the patterns of the L1. The present study aimed to produce a systematic review of the studies concerning attention and L2 phonological knowledge. Research participants, attention and phonological assessment, and the main results of eighteen studies published between 2010 and 2021 were described and analyzed. The data gathered indicates that the bulk of the research carried out is of cross-sectional studies with attention control and perceptual discrimination tasks with L2 English adult learners. Most studies pointed out that attention has an important role in L2 phonological acquisition. At the beginning of acquisition, attention seems to be more important to L2 speech processing than for proficient L2 speakers when automatization takes place. Focusing, selecting, shifting, dividing, and sustaining attention as well as being flexible and having good inhibitory control have a special role in L2 phonological acquisition. The need for further investigation with controlled variables, other L1/L2 combinations, and multiple assessment instruments is evident.

Conscientiousness Predicts Performance on the Stroop Task but Not Other Attentional Control Tasks in Older and Younger Adults

The current study examined the relationships between attentional control (AC) and the Big Five personality traits. Older and younger adults ( Mage = 38.62 years; Range = 18–90) completed a battery of behavioral attention tasks consisting of Stroop color naming, antisaccade, and operation span, which were designed to assess inhibition, goal maintenance, and working memory processes as a comprehensive assessment of AC. Participants then completed a set of personality scales including the NEO-FFI short form. Regression analyses revealed that Big Five personality scores were not related to the AC composite, but individual task relationships were found. Specifically, participants reporting greater Conscientiousness showed improved Stroop performance, but a Conscientiousness benefit did not extend to the other AC measures. No relationships emerged between other Big Five traits and AC. This work suggests potential cognitive benefits for Conscientiousness in older and younger adults and highlights a fruitful integration of personality and basic cognitive processes.

Nature and measurement of attention control.

Individual differences in the ability to control attention are correlated with a wide range of important outcomes, from academic achievement and job performance to health behaviors and emotion regulation. Nevertheless, the theoretical nature of attention control as a cognitive construct has been the subject of heated debate, spurred on by psychometric issues that have stymied efforts to reliably measure differences in the ability to control attention. For theory to advance, our measures must improve. We introduce three efficient, reliable, and valid tests of attention control that each take less than 3 min to administer: Stroop Squared, Flanker Squared, and Simon Squared. Two studies (online and in-lab) comprising more than 600 participants demonstrate that the three "Squared" tasks have great internal consistency (avg. = .95) and test-retest reliability across sessions (avg. r = .67). Latent variable analyses revealed that the Squared tasks loaded highly on a common factor (avg. loading = .70), which was strongly correlated with an attention control factor based on established measures (avg. r = .81). Moreover, attention control correlated strongly with fluid intelligence, working memory capacity, and processing speed and helped explain their covariation. We found that the Squared attention control tasks accounted for 75% of the variance in multitasking ability at the latent level, and that fluid intelligence, attention control, and processing speed fully accounted for individual differences in multitasking ability. Our results suggest that Stroop Squared, Flanker Squared, and Simon Squared are reliable and valid measures of attention control. The tasks are freely available online: https://osf.io/7q598/.

Anti-saccades reveal impaired attention control over negative social evaluation in individuals with depressive symptoms

Depressed individuals are excessively sensitive to negative information but blunt to positive information, which has been considered as vulnerability to depression. Here, we focused on inhibitory control over attentional bias on social evaluation in individuals with depression. We engaged individuals with and without depressive symptoms (categorized by Beck Depression Inventory-II) in a novel attention control task using positive and negative evaluative adjectives as self-referential feedback given by social others. Participants were instructed to look at sudden onset feedback targets (pro-saccade) or the mirror location of the targets (anti-saccade) when correct saccade latencies and saccade errors were collected. The two indices showed that while both groups displayed longer latencies and more errors for anti-saccade relative to pro-saccade responses depressed individuals spent more time reacting correctly and made more errors than non-depressed individuals in the anti-saccade trials and such group differences were not observed in the pro-saccade trials. Although group differences in correct anti-saccade latencies were found for both positive and negative stimuli, depressed individuals spent more time making correct anti-saccade responses to negative social feedback than to positive ones whereas non-depressed individuals featured longer correct anti-saccade latencies for positive relative to negative evaluations. Our results suggest that depressed individuals feature an impaired ability in attention control for self-referential evaluations, notably those of negative valence, shedding new light on depression-distorted self-schema and corresponding social dysfunctions.

Effects of different types of interference on nurses' working memory: An ERP study.

To explore the effects of different types of interference on nurses' working memory, and the role of attention control. A repeated measures design. A single-factor, four-level within-subjects design was adopted. Thirty-one nurses completed a delay-recognition task with four blocks in September 2020: Interrupting Stimulus (stimuli requiring attention), Distracting Stimulus (stimuli to-be-ignored), No Interference and Passively View. Behavioural responses of the participants and EEG data were recorded. MATLAB 21b and EEGLAB 21b were used for electroencephalogram data preprocessing and data extraction. Firstly, when nursing information system was used as task material, the accuracy rate and false alarm rate of primary tasks under interruption condition was statistically significantly different with that of distraction and no interference condition. There is a statistically significant difference in electroencephalogram measurement between correct and wrong response under interruption. Secondly, the role of attention control was different under interruption and distraction. There was a statistically significant positive correlation between the average amplitude distraction attention control index and task accuracy, and statistically significant negative correlation between the latency interruption attention control index and the accuracy of working memory task. There were different effects of interruptions and distractions on nurses' working memory and the role of attention control were also different. Measures can be designed according to these results to reduce the negative impact of interference on nurses, so as to improve work efficiency and reduce patient risk. This study has implications for clinical nursing during human-computer interaction. Resumption of the speed of the target information after an interruption affected task performance. Therefore, interventions should be designed to reduce the time needed for nurses to extract task information after an interruption, such as providing key clues in the information system interface. Registered nurses participated in the study as subjects.

Replication and extension of the toolbox approach to measuring attention control.

There is an increasing consensus among researchers that traditional attention tasks do not validly index the attentional mechanisms that they are often used to assess. We recently tested and validated several existing, modified, and new tasks and found that accuracy-based and adaptive tasks were more reliable and valid measures of attention control than traditional ones, which typically rely on speeded responding and/or contrast comparisons in the form of difference scores (Draheim et al. Journal of Experimental Psychology: General, 150(2), 242-275,2021). With these improved measures, we found that attention control fully mediated the working memory capacity-fluid intelligence relationship, a novel finding that we argued has significant theoretical implications. The present study was both a follow-up and extension to this "toolbox approach" to measuring attention control. Here, we tested updated versions of several attention control tasks in a new dataset (N = 301) and found, with one exception, that these tasks remain strong indicators of attention control. The present study also replicated two important findings: (1) that attention control accounted for nearly all the variance in the relationship between working memory capacity and fluid intelligence, and (2) that the strong association found between attention control and other cognitive measures is not because the attention control tasks place strong demands on processing speed. These findings show that attention control can be measured as a reliable and valid individual differences construct, and that attention control shares substantial variance with other executive functions.

Neurophysiological changes associated with vibroacoustically-augmented breath-focused mindfulness for dissociation: targeting interoception and attention.

Dissociative symptoms can emerge after trauma and interfere with attentional control and interoception; disruptions to these processes are barriers to mind-body interventions such as breath-focused mindfulness (BFM). To overcome these barriers, we tested the use of an exteroceptive augmentation to BFM, using vibrations equivalent to the amplitude of the auditory waveform of the actual breath, delivered via a wearable subwoofer in real time (VBFM). We tested whether this device enhanced interoceptive processes, attentional control and autonomic regulation in trauma-exposed women with dissociative symptoms. 65 women, majority (82%) Black American, aged 18-65 completed self-report measures of interoception and 6 BFM sessions, during which electrocardiographic recordings were taken to derive high-frequency heart rate variability (HRV) estimates. A subset (n = 31) of participants completed functional MRI at pre- and post-intervention, during which they were administered an affective attentional control task. Compared to those who received BFM only, women who received VBFM demonstrated greater increases in interoception, particularly their ability to trust body signals, increased sustained attention, as well as increased connectivity between nodes of emotion processing and interoceptive networks. Intervention condition moderated the relationship between interoception change and dissociation change, as well as the relationship between dissociation and HRV change. Vibration feedback during breath focus yielded greater improvements in interoception, sustained attention and increased connectivity of emotion processing and interoceptive networks. Augmenting BFM with vibration appears to have considerable effects on interoception, attention and autonomic regulation; it could be used as a monotherapy or to address trauma treatment barriers.

Attentional Control Moderates the Relation between Sympathy and Ethical Guilt

In response to ethical transgressions, some children respond with ethical guilt (e.g., remorse), while others do not. The affective and cognitive precursors of ethical guilt have been widely studied on their own, however, few studies have looked at the interaction of affective (e.g., sympathy) and cognitive (e.g., attention) precursors on ethical guilt. This study examined the effects of children’s sympathy, attentional control, and their interaction on 4 and 6-year-old children’s ethical guilt. A sample of 118 children (50% girls, 4-year-olds: Mage = 4.58, SD = .24, n = 57; 6-year-old: Mage = 6.52, SD = .33, n = 61) completed an attentional control task and provided self-reports of dispositional sympathy and ethical guilt in response to hypothetical ethical violations. Sympathy and attentional control were not directly associated with ethical guilt. Attentional control, however, moderated the relation between sympathy and ethical guilt, such that sympathy was more strongly related to ethical guilt at increasing levels of attentional control. This interaction did not differ between 4- and 6-year-olds or boys and girls. These findings illustrate an interaction between emotion and cognitive processes and suggest that promoting children’s ethical development may require a focus on both attentional control and sympathy.

A preliminary neuroimaging investigation of the effects of mindfulness training on attention reorienting andamygdala reactivity to emotional faces in adolescent and adult females.

Adolescence is a time of increased emotional reactivity and improving cognitive control. Mindfulness meditation training may foster adolescents' cognitive control and emotional regulation skills; however little is known about the impact of mindfulness training in adolescents compared to adults. We examined the effect of mindfulness meditation versus a closely matched active control condition (relaxation training) on behavioral and neural measures of cognitive control and emotional reactivity in a small group of adolescents and adults. Structural and functional magnetic resonance imaging data were collected before and after 8 weeks of training in 26 adolescent (12-14 years) and 17 adult (23-33 years) female participants in the United Kingdom while they completed an n-back task with emotional face distractors and an attentional control task. Participants of each group chose a class date/time and the classes were then randomly allocated to mindfulness or relaxation conditions. Compared to relaxation training, mindfulness training led to an increase in the speed of reorienting attention across age groups. In addition, there was preliminary evidence for reduced amygdala response to emotional face distractors in adolescents after mindfulness training. An 8-week mindfulness program showed similar facilitative effects in adolescent and adult females on the reorienting of attention, a skill that is repeatedly practiced during mindfulness meditation. Mindfulness also reduced left amygdala reactivity to emotional face distractors in adolescents only. Mindfulness meditation practice can therefore have a facilitative effect on female adolescents' attentional control, and possibly attenuate their emotional reactivity.

Effects of total sleep deprivation on components of top-down attentional control using a flexible attentional control task.

Sleep deprivation consistently decreases vigilant attention, which can lead to difficulty in performing a variety of cognitive tasks. However, sleep-deprived individuals may be able to compensate for degraded vigilant attention by means of top-down attentional control. We employed a novel task to measure the degree to which individuals overcome impairments in vigilant attention by using top-down attentional control, the Flexible Attentional Control Task (FACT). The FACT is a two-choice task that has trials with valid, invalid, and neutral cues, along with an unexpected switch in the probability of cue validity about halfway in the task. The task provides indices that isolate performance components reflecting vigilant attention and top-down attentional control. Twelve healthy young adults completed an in-laboratory study. After a baseline day, the subjects underwent 39 hours of total sleep deprivation (TSD), followed by a recovery day. The FACT was administered at 03:00, 11:00, and 19:00 during sleep deprivation (TSD condition) and at 11:00 and 19:00 after baseline sleep and at 11:00 after recovery sleep (rested condition). When rested, the subjects demonstrated both facilitation and interference effects on cued trials. While sleep deprived, the subjects showed vigilant attention deficits on neutral cue trials, and an impaired ability to reduce these deficits by using predictive contextual cues. Our results indicate that the FACT can dissociate vigilant attention from top-down attentional control. Furthermore, they show that during sleep deprivation, contextual cues help individuals to compensate partially for impairments in vigilant attention, but the effectiveness of top-down attentional control is diminished.

Reduced Glx and GABA Inductions in the Anterior Cingulate Cortex and Caudate Nucleus Are Related to Impaired Control of Attention in Attention-Deficit/Hyperactivity Disorder.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that impairs the control of attention and behavioral inhibition in affected individuals. Recent genome-wide association findings have revealed an association between glutamate and GABA gene sets and ADHD symptoms. Consistently, people with ADHD show altered glutamate and GABA content in the brain circuitry that is important for attention control function. Yet, it remains unknown how glutamate and GABA content in the attention control circuitry change when people are controlling their attention, and whether these changes can predict impaired attention control in people with ADHD. To study these questions, we recruited 18 adults with ADHD (31–51 years) and 16 adults without ADHD (28–54 years). We studied glutamate + glutamine (Glx) and GABA content in the fronto-striatal circuitry while participants performed attention control tasks. We found that Glx and GABA concentrations at rest did not differ between participants with ADHD or without ADHD. However, while participants were performing the attention control tasks, participants with ADHD showed smaller Glx and GABA increases than participants without ADHD. Notably, smaller GABA increases in participants with ADHD significantly predicted their poor task performance. Together, these findings provide the first demonstration showing that attention control deficits in people with ADHD may be related to insufficient responses of the GABAergic system in the fronto-striatal circuitry.

Attention and executive control in varsity athletes engaging in strategic and static sports.

Examining non-sport-related cognitive tasks of attention and executive control in skilled athletes may provide insight into the acquisition of highly specific skills developed in experts as well as help identify successful performance in sport. Through a cross-sectional design, this study examined performance on aspects of attention and executive control among varsity athletes playing soccer (strategic sport) or track & field (static sport) using a computerized test of attention and executive control. Ninety-seven university athletes participating in soccer (n = 50) or track and field (n = 47) were included in the study. Domains of attention and executive control were examined using the Attention Network Test-Interactions (ANT-I). Mean reaction time (RT) and intra-individual variability (IIV) were compared between groups as measures of performance speed and performance stability respectively. Soccer players demonstrated overall faster RTs (p = 0.0499; ηp2 = .04) and higher response accuracy (p = .021, d = .48) on the ANT-I compared to track and field athletes. Faster RTs were observed for soccer players when presented with an alerting tone (p = .029, d = .45), valid orienting cue (p = .019, d = .49) and incongruent flanker (p = .031, d = .45). No significant group differences were observed in IIV (p = .083, d = .36). Athletes engaging in strategic sports (i.e., soccer) demonstrated faster performance under test conditions that required higher vigilance and conflict resolution. These findings suggest that engagement in strategic sports is associated with enhanced performance on non-sport-related cognitive tasks of attention and executive control.

The Nencki-Symfonia electroencephalography/event-related potential dataset: Multiple cognitive tasks and resting-state data collected in a sample of healthy adults

BackgroundOne of the goals of neuropsychology is to understand the brain mechanisms underlying aspects of attention and cognitive control. Several tasks have been developed as a part of this body of research, however their results are not always consistent. A reliable comparison of the data and a synthesis of study conclusions has been precluded by multiple methodological differences. Here, we describe a publicly available, high-density electroencephalography (EEG) dataset obtained from 42 healthy young adults while they performed 3 cognitive tasks: (i) an extended multi-source interference task; (ii) a 3-stimuli oddball task; (iii) a control, simple reaction task; and (iv) a resting-state protocol. Demographic and psychometric information are included within the dataset.Dataset ValidationFirst, data validation confirmed acceptable quality of the obtained EEG signals. Typical event-related potential (ERP) waveforms were obtained, as expected for attention and cognitive control tasks (i.e., N200, P300, N450). Behavioral results showed the expected progression of reaction times and error rates, which confirmed the effectiveness of the applied paradigms.ConclusionsThis dataset is well suited for neuropsychological research regarding common and distinct mechanisms involved in different cognitive tasks. Using this dataset, researchers can compare a wide range of classical EEG/ERP features across tasks for any selected subset of electrodes. At the same time, 128-channel EEG recording allows for source localization and detailed connectivity studies. Neurophysiological measures can be correlated with additional psychometric data obtained from the same participants. This dataset can also be used to develop and verify novel analytical and classification approaches that can advance the field of deep/machine learning algorithms, recognition of single-trial ERP responses to different task conditions, and detection of EEG/ERP features for use in brain-computer interface applications.
