Investigating the role of mental imagery use in the assessment of anhedonia.

Anhedonia, or a deficit in the liking, wanting, and seeking of rewards, is typically assessed via self-reported "in-the-moment" emotional and motivational responses to reward stimuli and activities. Given that mental imagery is known to evoke emotion and motivational responses, we conducted two studies to investigate the relationship between mental imagery use and self-reported anhedonia. Using a novel Reward Response Scale (adapted from the Dimensional Anhedonia Rating Scale, DARS; Rizvi et al., 2015) modified to assess deliberate and spontaneous mental imagery use, Study 1 (N = 394) compared uninstructed and instructed mental imagery use, and Study 2 (N = 586) conducted a test of replication of uninstructed mental imagery use. Results showed that greater mental imagery use was associated with higher reward response scores (Study 1 & 2), and this relationship was not moderated by whether imagery use was uninstructed or instructed (Study 1). Importantly, mental imagery use moderated the convergence between reward response and depression scale measures of anhedonia, with lower convergence for those reporting higher mental imagery use (Study 1 & 2). Results suggest that higher spontaneous mental imagery use may increase self-reported reward response and reduce the convergence between reward response scale and depression questionnaire measures of anhedonia.

The role of acute stress recovery in emotional resilience.

Background: Resilience refers to the process of demonstrating better outcomes than would be expected based on the adversity one experienced. Resilience is increasingly measured using a residual approach, which typically assesses adversity and mental health outcomes over a longitudinal timeframe. It remains unknown to what extent such a residual-based measurement of resilience is sensitive to variation in acute stress resilience, a candidate resilience factor. Methods: Fifty-seven emerging adults enrolled in tertiary education completed measures of adversity and emotional experiences. To assess stress recovery, participants were exposed to a lab-based adverse event from which a Laboratory Stress Resilience Index was derived. Results: We derived a residual-based measure of emotional resilience from regressing emotional experience scores onto adversity scores. This residual-based measure of emotional resilience predicted variance in the Laboratory Stress Resilience Index over and above that predicted by both a traditional resilience measure and the emotional experiences measure. These findings suggest that acute stress resilience may be a factor underpinning variation in emotional resilience, and that the residual-based approach to measuring resilience is sensitive to such variation in stress resilience.

A randomized controlled trial modifying insomnia-consistent interpretation bias in students.

This study aimed to determine the causal role of insomnia-consistent interpretation bias within the cognitive model of insomnia, by modifying this bias in students experiencing subclinical levels of insomnia and assessing subsequent effects on sleep parameters. A sample of 128 students underwent randomization to receive either a single session of online Cognitive Bias Modification-Interpretation (CBM-I) or a sham training. Participants then tracked their pre-sleep worry and sleep parameters for seven consecutive days. Interpretation bias was assessed using an encoding-recognition task specifically designed for insomnia-related interpretation bias. The CBM-I manipulation utilized ambiguous scenarios to redirect participants away from making insomnia-related interpretations. Results revealed that CBM-I effectively decreased insomnia-consistent interpretation bias compared to the sham treatment, with interpretation bias being absent post-training in the CBM-I group. This reduction did not lead to improvements in pre-sleep worry or any sleep parameters. This study has been the first to investigate the causal role of interpretation bias on symptoms of insomnia. Although results indicated this bias to be modifiable, its causality within the cognitive model proves to be more complicated. Future research focusing on optimization of cognitive bias modifications could shed more light on the effects of biased cognitions on insomnia symptoms.

Silenced Survivors: A Systematic Review of the Barriers to Reporting, Investigating, Prosecuting, and Sentencing of Adult Female Rape and Sexual Assault.

Sexual victimization of adult women remains an underreported crime. This systematic review identified and synthesized the barriers to reporting, investigating, prosecuting, and sentencing cases of sexual assault and rape against adult women in Western countries. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a comprehensive search was conducted on August 3, 2023, across databases including PsycINFO, MEDLINE, Cochrane Library, Scopus, ProQuest Central, Web of Science, MedNar, and ProQuest Dissertations & Theses. Studies meeting the inclusion criteria provided relevant information on the decision not to formally disclose, investigate, prosecute, or convict incidents of sexual assault and rape of adult women. We included 28 studies and identified 70 barriers in total. Identified barriers were most prevalent to reporting, followed by investigating, prosecuting, and, lastly, sentencing. Key themes in the barriers included lack of trust in the criminal justice system, internal reactions, rape myths and societal norms, and perpetrator characteristics. The identified barriers emphasize an urgent need for reform of the criminal justice system's response to sexual assault and rape. Prioritizing victim-survivors' needs, enhancing transparency of the criminal justice system, and addressing attrition rates are crucial. Future studies need to engage with diverse population to address all victim-survivors' needs and provide further insights into the challenges across all stages of the criminal justice system to enhance the outcome of rape and sexual assault cases.

Cognitive flexibility and resilience measured through a residual approach.

BACKGROUND AND OBJECTIVES: Resilience refers to the process through which individuals show better outcomes than what would be expected based on the adversity they experienced. Several theories have proposed that variation in resilience is underpinned by cognitive flexibility, however, no study has investigated this using an outcome-based measure of resilience. DESIGN: We used a residual-based approach to index resilience, which regresses a measure of mental health difficulties onto a measure of adversity experienced. The residuals obtained from this regression constitute how much better or worse someone is functioning relative to what is predicted by the adversity they have experienced. METHODS: A total of 463 undergraduate participants completed questionnaires of mental health difficulties and adversity, as well as a number-letter task-switching task to assess cognitive flexibility. RESULTS: Multiple regression analyses showed that better cognitive flexibility was not associated with greater resilience. CONCLUSIONS: Our findings do not support theoretical models that propose the existence of a relationship between cognitive flexibility and resilience. Future research may serve to refine the residual-based approach to measure resilience, as well as investigate the contribution of "hot" rather than "cold" cognitive flexibility to individual differences in resilience.

Negative attention bias and attentional control as mechanisms in the association between insomnia and depression in young people.

Evidence supports a causal role of insomnia in the development and maintenance of depression, yet mechanisms underlying this association in young people are not well established. Attention biases have been implicated separately in the sleep and depression fields and represents an important candidate mechanism. Poor sleep may lead to a negative attention bias (characteristic of depression) by impacting attentional control. This study assessed the hypothesis that attentional control and negative attention bias would sequentially mediate the relationship between insomnia and depressive symptoms in an unselected sample of young people (17-24 years). Concerns have been raised regarding the psychometric properties of tasks used to measure attention bias, and a Dual-Probe Task is emerging as a more reliable measure. Participants (N = 275, Male = 59, Mage = 19.40) completed the Dual-Probe Task, a behavioural measure of attentional control, and self-report measures of insomnia and depression. Participants completed a one-week sleep diary. Results were consistent with negative attention bias, but not attentional control, as a mechanism which partially accounts for the relationship between sleep (i.e., insomnia severity, sleep duration, sleep efficiency, sleep latency) and depression. This study highlights sleep and negative attention bias as potentially modifiable risk factors to reduce depressive symptoms in young people.

Contamination fear and attention bias variability early in the COVID-19 pandemic.

The onset of the COVID-19 pandemic resulted in a dramatic increase in the salience and importance of information relating to both the risk of infection, and factors that could mitigate against such risk. This is likely to have contributed to elevated contamination fear concerns in the general population. Biased attention for contamination-related information has been proposed as a potential mechanism underlying contamination fear, though evidence regarding the presence of such biased attention has been inconsistent. A possible reason for this is that contamination fear may be characterised by variability in attention bias that has not yet been examined. The current study examined the potential association between attention bias variability for both contamination-related and mitigation-related stimuli, and contamination fear during the early stages of the COVID-19 pandemic. A final sample of 315 participants completed measures of attention bias and contamination fear. The measure of average attention bias for contamination-related stimuli and mitigation-related stimuli was not associated with contamination fear (r = 0.055 and r = 0.051, p > 0.10), though both attention bias variability measures did show a small but statistically significant relationship with contamination fear (r = 0.133, p < 0.05; r = 0.147, p < 0.01). These attention bias variability measures also accounted for significant additional variance in contamination fear above the average attention bias measure (and controlling for response time variability). These findings provide initial evidence for the association between attention bias variability and contamination fear, underscoring a potential target for cognitive bias interventions for clinical contamination fear.

Cognitive Biases and Insomnia Symptoms in People With and Without Chronic Pain.

Chronic pain and insomnia symptoms are highly comorbid; however, the psychological mechanisms driving this comorbidity are not well understood. The aim of the present study was to assess whether 2 cognitive biases that occur separately in chronic pain and insomnia, that is, interpretation bias and attentional bias, are heightened in people with comorbid chronic pain and elevated insomnia symptoms. A final sample of N = 109 people with chronic pain and N = 79 people without pain who varied in insomnia symptoms were recruited through Prolific Academic to complete this cross-sectional study. Participants completed measures of sleep and pain-related interpretation bias (ambiguous sentences task) and attentional bias (dot-probe task), as well as questionnaires assessing insomnia symptoms, pain symptoms, and general psychological symptoms. We found an interaction between pain status and insomnia symptoms for sleep-related interpretation bias. That is, people with chronic pain showed greater sleep-related interpretation bias than those without pain, but only when insomnia symptoms were also elevated. This interaction did not extend to pain interpretation bias or attentional bias, although we did find an elevated pain interpretation bias in people with chronic pain compared to pain-free individuals. We also found that both pain and sleep-related interpretation bias were associated with depression symptoms, suggesting that interpretation bias could potentially drive a trimorbidity of chronic pain, insomnia, and depression. Taken together, these findings suggest promise for the role of interpretation bias in the mutual maintenance of chronic pain and insomnia symptoms and the importance of also considering depression. PERSPECTIVE: This article presents data on the cognitive biases that are present in chronic pain, and that are associated with increased insomnia symptoms. Identifying such cognitive biases could help in explaining the high comorbidity between chronic pain and insomnia, leading to more effective and targeted treatments.

Examining the role of trait anxiety and attentional bias to negative information in intrusion vulnerability following an emotionally negative event.

BACKGROUND AND OBJECTIVES: Research shows that individuals with heightened trait anxiety are more likely to experience intrusions; however, the mechanism that accounts for this relationship is unclear. Two alternative hypotheses were tested to determine the nature of the associations between trait anxiety, attentional bias to negative information, and intrusion vulnerability. METHODS: Intrusions were elicited using the trauma film paradigm, and post-event attentional bias to negative information was assessed using the dot-probe task. Participants then completed a week-long intrusions diary. RESULTS: Results showed that attentional bias to negative information mediated the effect of heightened trait anxiety on elevated intrusion frequency. It was also revealed that heightened trait anxiety was associated with elevated intrusion-related distress, though attentional bias to negative information did not mediate this relationship. LIMITATIONS: Our sample was comprised of undergraduate students who were not selected based on a previous pathology. Replication in clinical samples is warranted. CONCLUSIONS: These findings provide new insight regarding individual differences in the experience of intrusions and suggest that both the frequency and distress associated with intrusions could represent clinical targets.

Assessing anxiety-linked impairment in attentional control without eye-tracking: The masked-target antisaccade task.

Contemporary cognitive theories of anxiety and attention processing propose that heightened levels of anxiety vulnerability are associated with a decreasing ability to inhibit the allocation of attention towards task-irrelevant information. Existing performance-based research has most often used eye-movement assessment variants of the antisaccade paradigm to demonstrate such effects. Critically, however, eye-movement assessment methods are limited by expense, the need for expert training in administration, and limited mobility and scalability. These barriers have likely led to researchers' use of suboptimal methods of assessing the relationship between attentional control and anxiety vulnerability. The present study examined the capacity for a non-eye-movement-based variant of the antisaccade task, the masked-target antisaccade task (Guitton et al., 1985), to detect anxiety-linked differences in attentional control. Participants (N = 342) completed an assessment of anxiety vulnerability and performed the masked-target antisaccade task in an online assessment session. Greater levels of anxiety vulnerability predicted poorer performance on the task, consistent with findings observed from eye-movement methods and with cognitive theories of anxiety and attention processing. Results also revealed the task to have high internal reliability. Our findings indicate that the masked-target antisaccade task provides a psychometrically reliable, low-cost, mobile, and scalable assessment of anxiety-linked differences in attentional control.

An empirical evaluation of The Resilience Shield model.

BACKGROUND: Resilience refers to the process through which individuals deal with the adversity they experience. Previous research has shown there are multiple factors that contribute to individuals' resilience, leading to increasing interest in the development of multidimensional resilience models. Once such recently proposed model is The Resilience Shield, which clusters groups of protective factors into different shield layers. The stronger these layers, the better the protection against adversity (Pronk et al. in The Resilience Shield, Pan Macmillan Australia, 2021). While this model was based in part on existing literature, no empirical evaluation has occurred to date. The aim of this study was therefore to evaluate the model fit for each of the modifiable shield layers and the overall model, and to examine whether each of the constructs included contributes to observed resilience scores. METHODS: Participants completed a series of questionnaires via The Resilience Shield website assessing constructs relevant to each resilience shield layer. Data from 3337 participants was analysed using Structural Equation Modelling and regression analyses. RESULTS: The results showed acceptable fit of the measurement model for the Social, Mind, and Professional Layers, but poor fit for the Body Layer. There was also good fit for the overall model. In addition, all but one of the constructs included in The Resilience Shield survey explained independent variance in either dispositional resilience scores, or dispositional vulnerability scores. CONCLUSION: These results broadly support the multidimensional structure proposed by The Resilience Shield model and suggest that (at least in the population in which it was tested) this may be an acceptable model to index individuals' performance on a range of indicators that contribute to resilience.

For there is nothing either good or bad: a study of the mediating effect of interpretation bias on the association between mindfulness and reduced post-traumatic stress vulnerability.

BACKGROUND: Despite increasing interest in the association between mindfulness and reduced trauma vulnerability, and the use of mindfulness in the latest interventions for Post-Traumatic Stress Disorder (PTSD), few studies have examined the mechanisms through which mindfulness may influence post-trauma psychopathology. The present study aimed to determine whether negative interpretation bias, the tendency to interpret ambiguous information as negative or threatening rather than positive or safe, mediates the association between higher levels of trait mindfulness and lower levels of PTSD symptoms. Negative interpretation bias was examined due to prior evidence indicating it is associated with being less mindful and post trauma psychopathology. METHODS: The study examined 133 undergraduate students who reported exposure to one or more potentially traumatic events in their lifetime. Participants completed self-report measures of trait mindfulness (Five Facet Mindfulness Questionnaire - Short Form; FFMQ-SF) and PTSD symptoms (Post-Traumatic Stress Disorder Checklist - Civilian version; PCL-C) as well an interpretation bias task that assessed the degree to which participants interpreted a range of everyday hypothetical scenarios to be threatening to their physical and/or psychological wellbeing. RESULTS: Results of a mediation analysis indicated a significant negative direct effect of trait mindfulness on PTSD symptomatology (p < .001). There was no evidence that negative interpretation bias mediated this relationship [BCa CI [-0.04, 0.03)], nor was it associated with trait mindfulness (p = .90) and PTSD symptomatology (p = .37). CONCLUSIONS: The results of the current study provide further evidence of the link between trait mindfulness and reduced post-trauma psychopathology while providing no support for the role of negative interpretation bias in this relationship.

Chronic Pain, Insomnia and their Mutual Maintenance: A Call for Cognitive Bias Research.

Chronic pain and insomnia are highly comorbid: Approximately 50% of those with chronic pain experience insomnia or clinically significant sleep disturbances, and 50% of those with insomnia experience chronic pain. Further, these conditions can be extremely disabling, particularly when they co-occur. There is increasing recognition of the need to tackle both chronic pain and insomnia together, as evidenced by growing empirical research in this area. Cognitive processing biases have been independently implicated in both chronic pain and in insomnia. Given their trans-diagnostic status, cognitive biases may therefore have a role in explaining the co-occurrence and mutual maintenance of these conditions. These biases also represent novel, potentially modifiable targets for treatment. However, the role of cognitive biases has not been adequately explored in comorbid chronic pain and insomnia. Here, we describe the state of cognitive bias research in chronic pain and insomnia, considering evidence for the roles of attentional bias, interpretation bias, expectancy bias, and memory bias. In reviewing the literature, it is apparent that similar cognitive biases operate in insomnia and chronic pain, with preliminary, albeit sparse, evidence of pain-related cognitive biases influencing sleep-related outcomes. On the basis of current findings and separate theoretical models, we present a novel, testable cognitive model of comorbid chronic pain and insomnia, to guide future research in this area. Key recommendations for the future of this relatively new field are provided. PERSPECTIVE: Chronic pain and insomnia are highly co-morbid, suggesting an overlap in causal mechanisms. Empirical research, although sparse, suggests that cognitive biases may play a role in their development and mutual maintenance. Our novel cognitive model generates research avenues of clinical importance for treating co-morbid chronic pain and insomnia.

Gamification of cognitive bias modification for interpretations in anxiety increases training engagement and enjoyment.

BACKGROUND AND OBJECTIVES: Interpretation bias plays a crucial role in anxiety. To test the causal role and potential clinical benefits, training procedures were developed to experimentally change interpretation bias. However, these procedures are monotonous and plain, which could negatively affect motivation and adherence. The aim of this study was to make the interpretation training more engaging and enjoyable, without compromising its effectiveness, through gamification. METHODS: The training was gamified by including extrinsically and intrinsically motivating elements such as points, scores, time-pressure, fun and adaptive elements (training at an individually challenging level). A 2 (Type: Gamified vs. Standard) x 2 (Training Valence: Positive vs. Placebo) between-subjects design was used with random allocation of 79 above-average anxious individuals. Post-training, we assessed the liking and recommendation of the training task, interpretation bias (Recognition task and the Scrambled Sentence Task) and anxiety. RESULTS: Participants experienced the gamified training tasks as more engaging and enjoyable than the standard tasks, although it was not recommend more to fellow-students. Both positive training conditions (gamified and standard) were successful in eliciting a positive interpretation bias when assessed with the Recognition task, while only the standard positive training impacted on interpretations when assessed with the Scrambled Sentence Task. No differential effects were observed on anxiety. LIMITATIONS: The study involved only a single-session training and participants were selected for high trait (and not social) anxiety. CONCLUSIONS: The gamified training was evaluated more positively by the participants, while maintaining the effectiveness of eliciting positive interpretations when assessed with the Recognition task. This suggests that gamification might be a promising new approach.

The Role of Distress Tolerance in the Relationship Between Affect and NSSI.

OBJECTIVE: Non-suicidal self-injury (NSSI), the deliberate and self-inflicted damage of body tissue, typically serves an emotion regulation function. Both negative and positive affectivity have been associated with NSSI, as has low distress tolerance. In the current study, we tested whether relationships between both negative and positive affectivity and NSSI are moderated by the four facets of distress tolerance (tolerance, absorption, appraisal, regulation) captured by the Distress Tolerance Scale. METHODS: A sample of 531 university students completed well-validated measures of NSSI, negative affectivity, positive affectivity, and distress tolerance. RESULTS: Findings indicate that negative and positive affectivity, as well as the appraisal (i.e. negative perceptions of distress) and absorption (i.e. allocation of attention to distress) facets of distress tolerance, were directly associated with NSSI. Positive affectivity and appraisal also interacted in differentiating participants with recent, lifetime and no history of NSSI. Specifically, the association between negative perceptions of distress and self-injury was weaker at high levels of positive affectivity. Positive affectivity and absorption also interacted to differentiate between individuals with no history of NSSI and individuals who recently engaged in NSSI. Specifically, positive affectivity was negatively associated with self-injury, but only among individuals who allocate less attention to their distress. CONCLUSIONS: Considering the independent roles of negative and positive affectivity alongside specific facets of distress tolerance and their interactions with emotional experience, may enhance understanding of NSSI. Prevention and intervention initiatives that assist regulation of negative affectivity, increase positive affectivity, and improve distress tolerance, may reduce the likelihood of engaging in self-injury.HighlightsNegative and positive affectivity are independently associated with NSSIAppraisal and absorption facets of distress tolerance are associated with NSSIPositive affectivity moderates associations between appraisal and absorption and NSSI.

The relationship between worry and attentional bias to threat cues signalling controllable and uncontrollable dangers.

People vary in the frequency with which they worry and there is large variation in the degree to which this worry disrupts their everyday functioning. Heightened tendency to experience disruptive worry is characterised by an attentional bias towards threat. While this attentional bias is often considered maladaptive, it can be adaptive when it concerns threat cues signalling dangers that can be mitigated through personal action. In this case, the resulting worry may increase the likelihood of this action being taken, with beneficial rather than disruptive consequences for everyday functioning. Thus, depending on its focus, attentional bias to threat could potentially drive worry that is high or low in disruptiveness. The current study addressed this possibility, by testing the novel hypothesis that the degree to which worry is disruptive is a function of the degree to which this attentional bias concerns all threat cues, rather than being restricted to threat cues signalling controllable dangers. Participants completed a novel probe task assessing their attention to threat cues signalling a future danger that could be controlled on some blocks, but not on others. Thus, the task revealed the degree to which their selective attention to threat cues was 'aligned' with danger controllability, by being more evident on blocks that permitted participant control of the danger signalled by the threat cues. The results indicate, contradicting the hypothesis under test, participants who reported high levels of disruptive worry demonstrated alignment of attentional bias to variations in danger controllability, whereas this was not the case for participants who reported high levels of non-disruptive worry. While caution is needed in the interpretation of the results due to methodological limitations, this study provides a new conceptual and methodological framework for future research on the attentional basis of individual differences in the tendency to experience disruptive vs non-disruptive worry.

Attentional processes and contamination-related intrusion distress.

Whilst people with high contamination fear may not experience a greater number of contamination-related intrusions than people with low contamination fear, they tend to experience heightened distress in response to such intrusions. The aim of the present study was to test the hypothesis that attentional bias to contamination-relevant information, and the variability of this attentional bias, moderates the degree to which high contamination fearful but not low contamination fearful individuals experience distress in response to contamination-related intrusions. Individuals with high (n = 31) or low (n = 44) contamination fear completed a lab-based session including questionnaires, a dot-probe measure of contamination-related attentional bias and attentional bias variability, and a contamination stressor video. Participants then completed a week-long contamination intrusions diary. There were significant differences in intrusion distress between those with low and high contamination fear in the anticipated direction, and attentional bias significantly moderated this relationship. Regardless of contamination fear level, greater attentional bias variability was associated with greater intrusion distress. These findings suggest that reducing attentional bias variability could potentially help to reduce distress elicited by contamination-related intrusions, while also highlighting the fact that attentional bias towards threat may protect against such distress in low contamination fearful individuals.

What is attention bias variability? Examining the potential roles of attention control and response time variability in its relationship with anxiety.

The present study examined the underlying role of attention control and response time variability in explaining the relationship between anxiety and two commonly computed measures of attention bias variability: 'moving average' and 'trial-level bias score' measures. Participants (final n = 195) completed measures of anxiety symptomatology, antisaccade performance (attention control), a stand-alone measure of response-time variability, and a probe task measure of attention bias. Average bias and moving average bias variability measures both recorded significant, but low split-half reliability. Both attention bias variability measures and average attention bias were associated with anxiety, and attention control. Both attention bias variability measures correlated with response time variability. Neither attention bias variability measure correlated with average attention bias. Attention control was the single significant mediator of the relationship between anxiety and the trial-level bias score measure of attention bias variability. Neither response time variability nor attention control significantly mediated the relationship between anxiety and the moving average measure of attention bias variability. No evidence was found for the mediating role of response time variability. The present findings suggest that the relationships observed between anxiety and the trial-level bias score measure of attention bias variability in particular may be attributable to the over-arching role of attention control.

The effects of left DLPFC tDCS on emotion regulation, biased attention, and emotional reactivity to negative content.

The potentiation of neural activity in lateral prefrontal regions via transcranial direct current stimulation (tDCS) can reduce patterns of biased attention for threat and may facilitate intentional emotion regulation. The current study sought to determine whether left dorsolateral prefrontal cortex tDCS, in combination with intentional down-regulation of emotional responses would reduce negative appraisals of aversive content during emotional regulation (assessed during online tDCS), reduce patterns of biased attention and attention bias variability (assessed offline), and attenuate spontaneous (uninstructed) emotional reactivity to negative content (assessed offline) above tDCS or intentional down-regulation of emotions in isolation. Healthy participants (n = 116) were allocated to one of four experimental conditions involving either active or sham tDCS, combined with an either a down-regulate or maintain emotion regulation task. Attention bias/bias variability was assessed with an attentional probe task, and emotional reactivity was assessed in a negative video viewing task. tDCS did not affect the appraisals of negative stimuli during emotion regulation, and there were no effects on attention bias/bias variability. However, tDCS did attenuate emotional reactivity. Those receiving active stimulation showed smaller elevations in negative mood in response to viewing aversive video content compared with sham. The present findings are consistent with the potential of left frontal tDCS to attenuate negative emotional reactions to aversive content but provide no support for tDCS enhancement of emotion regulation, nor its impact on attention bias or attention bias variability.

The effects of anxiety, depressive, and obsessive-compulsive subclinical symptoms on performance monitoring.

Dysfunctional performance monitoring has been proposed as a potential neurocognitive biomarker of various internalising psychopathological symptoms, such as anxiety, depressive, and obsessive-compulsive symptoms. Given the overlapping neurophysiological findings and high rates of comorbidity amongst these internalising symptoms, an important research gap pertains to the specificity of performance monitoring to each of these symptoms. The aim of the present study was to examine the effects of anxiety, depressive, and obsessive-compulsive symptoms on performance monitoring in healthy adults. The sample consisted of 50 participants, with ages ranging from 18 to 33 years (M = 22.82, SD = 3.84). The Depression, Anxiety, and Stress Scales-21 and the Obsessive Compulsive Inventory-Revised were administered to assess the various internalising symptoms. An arrow flanker task was administered to elicit error responses whilst electrophysiological data were recorded from the scalp. Performance monitoring was indexed by the error-related negativity and correct response negativity. Bivariate correlations revealed that the three internalising symptoms were not associated with error-related negativity or correct response negativity amplitudes. However, a regression model revealed that greater levels of anxiety symptoms were uniquely associated with larger error-related negativity amplitude after controlling for depressive symptoms. In addition, greater levels of depressive symptoms were uniquely associated with smaller error-related negativity amplitude. Another regression model revealed that greater levels of depressive symptoms were uniquely associated with smaller correct response negativity amplitude after controlling for anxiety symptoms. These findings suggest that performance monitoring differentially associates with anxiety and depressive symptoms amongst healthy adults, providing some evidence of specificity for each respective symptoms.
