The error-related negativity (ERN)-an index of error monitoring-is associated with anxiety symptomatology. Although recent work suggests associations between the ERN and anxiety are relatively modest, little attention has been paid to how variation in task parameters may influence the strength of ERN-anxiety associations. To close this gap, the current meta-analysis assesses the possible influence of task parameter variation in the Flanker task-the most commonly used task to elicit the ERN-on observed ERN-anxiety associations.

Background: Childhood anxiety symptoms have been linked to alterations in cognitive control and error processing, but the diverse findings on neural markers of anxiety in young children, which vary by severity and developmental stage, suggest the need for a wider perspective. Integrating new neural markers with established ones, such as the error-related negativity, the error positivity, and frontal theta, could clarify this association. Error-related alpha suppression (ERAS) is a recently proposed index of post-error attentional engagement that has not yet been explored in children with anxiety.

Accumulating evidence suggests that a focus on women's health and ovarian hormones is critical to the study of such cognitive brain functions. Here we sought to identify a novel index of error monitoring using a time-frequency based phase amplitude coupling (t-f PAC) measure and examine its modulation by endogenous levels of estradiol in females.
View Article and Find Full Text PDFBackground: Increased reactivity to response conflict and errors, processes governed by the dorsal anterior cingulate cortex (dACC), have both been implicated in anxiety. Anxiety is also more common in females than males. Importantly, natural changes in ovarian hormones levels are related to fluctuations in anxiety symptoms in healthy and clinical populations, and ovarian hormones likely modulate prefrontal cortex structure and function.

We investigated the transfer effects of online adaptive cognitive training (dual n-back training) on subjective and objective cognitive markers in a longitudinal design.
Methods: Women with a primary diagnosis of breast cancer completed 12 sessions of adaptive cognitive training or active control training over 2 weeks.
The recent decade has brought an exciting proliferation of behavioral, psychological and neuroscientific research involving the menstrual cycle. However, the reliability and validity of many popular methodologies for determining menstrual cycle phase lack empirical examination. These under-investigated methods include: (1) predicting menstrual cycle phase using self-report information only (e.

Genetic and hormonal factors can shape individual differences in prefrontal DA tone. The catechol-o-methyltransferase (COMT) gene regulates basal prefrontal DA, and the sex hormone 17β-estradiol potentiates DA release.

However, there are mixed findings regarding whether affective symptoms change across the menstrual cycle in females without a clinical diagnosis. The window of vulnerability model proposes that natural increases in ovarian hormones in the mid-luteal phase of the menstrual cycle lead to systematic changes in brain networks associated with affective processing.

However, it is unclear where people are exposed to these beliefs. This study examined beliefs about depression and their relations to symptoms, attitudes about depression, and treatment preferences.

The current study established and pilot-tested "Camp Kidpower"-a novel group-based, interactive CC training intervention-and assessed its impacts on behavioral and neurophysiological indices of CC among preschool children with elevated anxiety symptoms.
Methods: Forty-four anxious children (4-6 years) were enrolled in Camp Kidpower, delivered in four sessions over 10 days.
Emotion regulation is critical for managing stress, but many regulatory strategies consume high levels of cognitive resources to implement, which are depleted under stress. This raises a conundrum: the tools we have to feel better may be ineffective when they are most needed. Recent event-related potential (ERP) research indicates that distanced self-talk (i.

An enlarged error-related negativity (ERN) - an electrophysiological marker of cognitive control-related error monitoring- represents one indicator of neural processes more strongly related to anxiety in women than men. In this study, we further examined this association in women by testing the moderating effect of hormonal contraceptive (HC) use on the relationship between worry - i.

Thus, we iteratively refined techniques for EEG collection in three cohorts of children with anxiety enrolled in our study of a novel intervention. Techniques involved directing child attention away from the EEG setup (Cohort 1, N = 18), open discussion of equipment and processes during setup (Cohort 2, N = 21), and a preparatory EEG-exposure session prior to data collection (Cohort 3, N = 6).

Whilst cancer-related cognitive impairments (CRCI) are often reported amongst breast cancer survivors, investigation into the capacity to efficiently process errors is limited. The present study investigated the neurocognitive correlates of cognitive-control related performance monitoring, an important function influencing behavioural adjustment to mistakes.

Extant research indicates that worry is associated with reduced working memory. It remains unclear, however, what mechanisms contribute to impaired performance in worriers. Critically, dopamine in the prefrontal cortex heavily influences the stability of mental representations during working memory tasks, yet no research has probed its role in associations between worry and working memory.

However, anxiety has also been found to relate to less efficient cognitive processing as well as a greater reliance on action monitoring processes. Given the extant body of evidence demonstrating that single bouts of exercise result in cognitive enhancements; the present investigation sought to determine the extent to which exercise might be effective at reducing these anxiety-related impairments in cognition.

Moreover, prior work demonstrates that estradiol relates to both worry and working memory performance. In the present study, we sought to further examine interrelations between worry, estradiol and working memory by testing whether estradiol moderates the association between worry and working memory in females.

To determine the extent to which neutral, negative, and positively valenced emotional conditions modulate startle response in early life, a child-friendly film paradigm was used to vary emotion across these conditions during startle induction in sixty-four 4- to 7-year-old children. Association of emotion-modulated startle with parent-reported anxiety symptom severity and child behavioral inhibition, a risk factor for anxiety problems, were assessed.

Despite a growing literature supporting the salutary effects of mindfulness meditation on emotion regulation, the underlying mechanisms linking neural and subjective changes occurring during the actual practice of meditation with emotion regulatory effects observed after meditation remains virtually unexplored. The current study sought to address this gap in knowledge by testing the hypothesis that adoption of internally-directed focused attention, indexed by increased alpha and theta spectral power, during brief open monitoring (OM) mindfulness meditation predicts reduced emotional reactivity, as measured by the late positive potential (LPP). Results revealed that the OM meditation did not produce demonstrable differences in alpha and theta power but did increase self-reported sleepiness relative to controls.
