novelty n2 p3a complex and theta oscillations reflect improving neural coordination within frontal brain networks during adolescence
Frontiers in Behavioral Neuroscience, 2018Co-Authors: Annika Susann Wienke, Canan Basareroglu, Christina Schmiedtfehr, Birgit MathesAbstract:Adolescents are easier distracted by novel items than adults. Maturation of the frontal cortex and its integration into widely distributed brain networks may result in diminishing Distractibility with the transition into young adulthood. The aim of this study was to investigate maturational changes of brain activity during novelty processing. We hypothesized that during adolescence, timing and task-relevant modulation of frontal cortex network activity elicited by novelty processing improves, concurrently with increasing cognitive control abilities. A visual novelty oddball task was utilized in combination with EEG measurements to investigate brain maturation between 8 to 28 years of age (n = 84). Developmental changes of the frontal N2-P3a complex and concurrent theta oscillations (4–7 Hz) elicited by rare and unexpected novel stimuli were analyzed using regression models. N2 amplitude decreased, P3a amplitude increased, and latency of both components decreased with age. Pre-stimulus amplitude of theta oscillations decreased, while inter-trial consistency, task-related amplitude modulation and inter-site connectivity of frontal theta oscillations increased with age. Targets, intertwined in a stimulus train with regular non-targets and novels, were detected faster with increasing age. These results indicate that neural processing of novel stimuli became faster and the neural activation pattern more precise in timing and amplitude modulation. Better inter-site connectivity further implicates that frontal brain maturation leads to global neural reorganization and better integration of frontal brain activity within widely distributed brain networks. Faster target detection indicated that these maturational changes in neural activation during novelty processing may result in diminished Distractibility and increased cognitive control to pursue the task.

distracted by your mind individual differences in Distractibility predict mind wandering
Journal of Experimental Psychology: Learning Memory and Cognition, 2014Co-Authors: Sophie Forster, Nilli LavieAbstract:Attention may be distracted from its intended focus both by stimuli in the external environment and by internally generated task-unrelated thoughts during mind wandering. However, previous attention research has focused almost exclusively on distraction by external stimuli, and the extent to which mind wandering relates to external distraction is as yet unclear. In the present study, the authors examined the relationship between individual differences in mind wandering and in the magnitude of distraction by either response-competing distractors or salient response-unrelated and task-irrelevant distractors. Self-reported susceptibility to mind wandering was found to positively correlate with task-irrelevant distraction but not with response-competition interference. These results reveal mind wandering as a manifestation of susceptibility to task-irrelevant distraction and establish a laboratory measure of general susceptibility to irrelevant distraction, including both internal and external sources.

Failures to ignore entirely irrelevant distractors: The role of load
J EXP PSYCHOL-APPL, 2008Co-Authors: Nilli LavieAbstract:In daily life (e.g., in the work environment) people are often distracted by stimuli that are clearly irrelevant to the current task and should be ignored. In contrast, much applied distraction research has focused on task interruptions by information that requires a response and therefore cannot be ignored. Moreover, the most commonly used laboratory measures of Distractibility (e.g., in the response-competition and attentional -capture paradigms), typically involve distractors that are task relevant (e.g., through response associations or location). A series of experiments assessed interference effects from stimuli that are entirely unrelated to the current task, comparing the effects of perceptual load on task-irrelevant and task-relevant (response competing) distractors. The results showed that an entirely irrelevant distractor can interfere with task performance to the same extent as a response-competing distractor and that, as with other types of distractors, the interfering effects of the irrelevant distractors can be eliminated with high perceptual load in the relevant task. These findings establish a new laboratory measure of a form of Distractibility common to everyday life and highlight load as an important determinant of such Distractibility.

mind wandering internal Distractibility in adhd a literature review
Journal of Attention Disorders, 2021Co-Authors: Jane Lanier, Elizabeth Noyes, Joseph BiedermanAbstract:Objective: Mind wandering, the unintended shifting of attention from a task, has been previously associated with symptoms of ADHD. To this end, we conducted a literature search to investigate the association between mind wandering and ADHD. Method: We conducted a systematic search of the literature of relevant articles assessing mind wandering and ADHD in PubMed, PsycINFO/OVID, and Medline. Included were original articles in English that had operationalized definitions of ADHD and mind wandering, adequate sample size, and reliance on statistical evaluation of findings. Excluded were reviews, opinions, and case reports. Results: Only nine studies met our a priori inclusion and exclusion criteria (N = 8 in adults; N = 1 in pediatrics). Findings suggest that ADHD is frequently associated with spontaneous mind wandering and when present heralds more functional impairments. Conclusion: The limited research on mind wandering in ADHD indicates that it is prevalent and morbid supporting further research on the subject.

towards operationalising internal Distractibility mind wandering in adults with adhd
Acta Neuropsychiatrica, 2017Co-Authors: Joseph Biederman, Maura Fitzgerald, Mai Uchida, Thomas J Spencer, Ronna Fried, Jennifer Wicks, Alexandra Saunders, Stephen V FaraoneAbstract:Objective To investigate whether specific symptoms of attention deficit hyperactivity disorder (ADHD) can help identify ADHD patients with mind wandering. Methods Subjects were adults ages 18–55 of both sexes (n=41) who completed the Mind-Wandering Questionnaire (MWQ) and the ADHD module of the Schedule for Affective Disorders and Schizophrenia for School-Age Children Epidemiologic Version. We used Spearman’s rank correlation and Pearson’s χ2 analyses to examine associations between the ADHD module and the MWQ and receiver operator characteristic (ROC) analyses to evaluate the diagnostic efficiency of the ADHD module. Results Out of the three ADHD domains, the inattentive ADHD scores had the strongest association with the MWQ (total: r s=0.34, df=39, p=0.03; inattentive: r s=0.38, df=39, p=0.02; Hyperactive: r s=0.17, df=39, p=0.28). Correlation analyses between individual items on the ADHD module and the MWQ showed that two inattention items (‘failure to pay attention to detail’ and ‘trouble following instructions’) were positively associated with total scores on the MWQ (p=0.02). These two inattention items had the strongest association with the MWQ (r s=0.45, df=38, p=0.004). ROC analyses showed that the combined score of the two significant inattention items had the highest efficiency (AUC=0.71) in classifying high-level mind wanderers as defined by scores greater than the median split on the MWQ. The combined score of the two inattention items best identified high-level mind wanderers. Conclusion Results suggest a way to operationalise mind wandering using the symptoms of ADHD.
