In a target discrimination task, trials with incorrect responses elicit event-related potentials (ERPs) that include an error-related negativity (ERN or Ne) and later error-positivity (Pe). Substantial evidence points to the anterior cingulate cortex as source generator of ERN. We examined development ERP component morphology, amplitude latency processing correct in 124 children, 7 18 years age, 27 adults, 19 through 25 age. The ERN Pe were recorded during standard 480-trial visual flanker...
ABSTRACT Practice on cognitive tasks, in general, and word recognition particular, will usually lead to faster more stable responding. We present an analysis of the relationship between observed reductions performance latency variability with respect whether processing has merely become across board or a qualitative change, such as automatization, taken place. The coefficient (CV) - standard deviation response time divided by mean is shown be useful for this purpose. A interpretation CV...
Abstract This study examines changes in the error‐related negativity (ERN/Ne) related to motivational incentives and personality traits. ERPs were gathered while adults completed a four‐choice letter task during four conditions. Monetary for finger hand accuracy altered across motivation conditions either be equal or favor one type of over other 3:1 ratio. Larger ERN/Ne amplitudes predicted with increased incentives, moderating this effect. Results as expected: Individuals higher on...
Psychologists consider emotion regulation a critical developmental acquisition. Yet, there has been very little research on the neural underpinnings of across childhood and adolescence. We selected two ERP components associated with inhibitory control—the frontal N2 P3. recorded these before, during, after negative induction, compared their amplitude, latency, source localization over age. Fifty-eight children 5–16 years age engaged in simple go/no-go procedure which points for successful...

Abstract Nineteen adolescents (average age 15 years, 3 months) were tested and retested using a standard 40 target, auditory oddball ERP paradigm across an interval of 1 year, 10 months to determine reliability the components, both in terms intersubject stability score agreement trait (between‐session reliability) versus state (within‐session reliability). Significant was found for N100, P200, P300 latencies ( r = .48, .51, .74, respectively), amplitude .62), supporting as reliable measure,...
Introduction: Subjective cognitive decline (SCD) in older adults is a condition with complex phenomenology and diverse etiologies including (but not limited to) mood, personality, health concerns, as well biomarkers of preclinical Alzheimer’s disease such amyloid-β deposition gray m atter volume loss. Approximately 60% affected persons are estimated to dementia. Regardless etiology, SCD may be optimal targets for early intervention. Objective:To ascertain the feasibility impact mindfulness...
Abstract This study investigated the development of automaticity in second language word recognition. In an earlier (Segalowitz & Segalowitz, 1993) we demonstrated that a reduction coefficient variation lexical decision reaction time (CV RT ) - standard deviation divided by mean (RT) reflects restructuring underlying cognitive processing mechanisms direction increased and not simple speed-up those mechanisms. current study, English speakers studying French performed multiple tasks....
Error trials are associated with faster responses than correct in simple discrimination tasks suggesting that errors result from impulsive responding. We investigated the relationship between error negativity (Ne/ERN), an event‐related potential detection, and two behavioral indices of response control: time (RT) differences incorrect (an index impulsivity) percentage errors. Response‐locked ERPs were collected 17 young adults during a visual flanker task. Consistent previous findings,...
The error-related negativity (ERN or Ne) and positivity (Pe) are event-related potential components elicited during simple discrimination tasks after an error response. ERN Pe have a fronto-central scalp distribution may be indirect measure of anterior cingulate (AC) activity as it relates to performance monitoring. Brain imaging studies suggest that obsessive-compulsive disorder (OCD) is associated with exaggerated the AC while electrophysiological found association between OCD pronounced...
The error-related negativity (ERN) and feedback-related (FRN) have been used as electrophysiological indices of performance monitoring produced in response to internally generated (errors) externally (feedback) activations the anterior cingulate cortex (ACC). No studies date systematically examined measurement reliability these components. In this article, we present retest ERN FRN during tasks designed elicit errors or feedback responses on two occasions. Data from four experiments are...
Children referred for externalizing behavior problems may not represent a homogeneous population. Our objective was to assess neural mechanisms of emotion regulation that might distinguish subtypes children from each other and their normal age mates. with pure (EXT) were compared comorbid internalizing (MIXED) age-matched controls. Only boys included in the analysis because so few girls treatment. We used go/no-go task negative induction, we examined dense-array EEG data together behavioral...
