“…The main factors accounting for these discrepancies are the clinical subtypes of patients included in these studies, with comorbidities inducing particular responses[ 72 ], higher artifact contamination in clinical patients than in typical subjects[ 27 ], a potential influence of medication[ 27 ], and differences in ERP recording protocols leading to data misinterpretations[ 73 ]. In this respect, a very interesting initiative, called “ERP CORE” (Compendium of Open Resources and Experiments)[ 74 ], has recently been launched in order to provide standardized ERP paradigms for seven widely used ERP components (N170, MMN, N2pc, N400, P3, lateralized readiness potential, and ERN). By providing researchers with a useful tool and guidelines for selected tasks to record specific ERP components, this will notably promote the possibility of comparing ERP data sets from different laboratories.…”

Relapse prevention remains a major challenge in psychiatry, thus indicating that the established treatment methods combining psychotherapy with neuropharmacological interventions are not entirely effective. In recent years, several intervention strategies have been devised that are aimed at improving psychiatric treatment by providing a complementary set of add-on tools that can be used by clinicians to improve current patient assessment. Among these, cognitive event-related potentials (ERPs) have been indexed as valuable biomarkers of the pathophysiological mechanisms of various mental illnesses. However, despite decades of research, their clinical utility is still controversial and a matter of debate. In this opinion review, I present the main arguments supporting the use of cognitive ERPs in the management of psychiatric disorders, stressing why it is currently still not the case despite the vast number of ERP studies to date. I also propose a clinically-oriented suitable way in which this technique could — in my opinion — be effectively incorporated into individual patient care by promotion of the use of individual ERP test-retest sessions and the use of a multi-component approach.

“…It seems especially relevant that demographic and clinical characteristics of participant samples included in studies are reported explicitly in publications: Effects can be classified more accurately, and addressed in replication studies as well as in reviews and meta-analytic approaches. Nevertheless, future studies should assess further different methodological variables, and efforts on methodological standardization for a higher comparability of study results should moreover be strengthened [43,44].…”

EEG Data Quality: Determinants and Impact in a Multicenter Study of Children, Adolescents, and Adults with Attention-Deficit/Hyperactivity Disorder (ADHD)

Electroencephalography (EEG) represents a widely established method for assessing altered and typically developing brain function. However, systematic studies on EEG data quality, its correlates, and consequences are scarce. To address this research gap, the current study focused on the percentage of artifact-free segments after standard EEG pre-processing as a data quality index. We analyzed participant-related and methodological influences, and validity by replicating landmark EEG effects. Further, effects of data quality on spectral power analyses beyond participant-related characteristics were explored. EEG data from a multicenter ADHD-cohort (age range 6 to 45 years), and a non-ADHD school-age control group were analyzed (ntotal = 305). Resting-state data during eyes open, and eyes closed conditions, and task-related data during a cued Continuous Performance Task (CPT) were collected. After pre-processing, general linear models, and stepwise regression models were fitted to the data. We found that EEG data quality was strongly related to demographic characteristics, but not to methodological factors. We were able to replicate maturational, task, and ADHD effects reported in the EEG literature, establishing a link with EEG-landmark effects. Furthermore, we showed that poor data quality significantly increases spectral power beyond effects of maturation and symptom severity. Taken together, the current results indicate that with a careful design and systematic quality control, informative large-scale multicenter trials characterizing neurophysiological mechanisms in neurodevelopmental disorders across the lifespan are feasible. Nevertheless, results are restricted to the limitations reported. Future work will clarify predictive value.

“…We would argue that conducting direct replications is especially challenging with ERP studies, which afford numerous additional "researcher degrees of freedom" that are often seemingly inconsequential but may create additional opportunities for false-positive findings (Luck & Gaspelin, 2017). While new efforts are emerging to help transparently address some of this flexibility (Kappenman et al, 2021), Clayson et al (2019) point out that insufficient following of accepted ERP experiment reporting guidelines and small sample sizes, hence low statistical power, greatly reduce the methodological transparency and replicability of ERP studies. In addition, to have a basis for generalizable claims, effects have to be replicable when the methods and equipment used are similar but not necessarily identical to the original study.…”

We report a replication of Boutonnet and Lupyan’s (2015) study of the effects of linguistic labelling on perceptual performance. In addition to a response time advantage of linguistic labels over non-linguistic auditory cues in judging visual objects, Boutonnet and Lupyan found that the two types of cues produced different patterns in the early perceptual ERP components P1 and P2 but not the later, semantics-relevant N4. This study thus adds an important piece of evidence supporting the claim of genuine top-down effects on perception. Given the controversy over this claim and the need for replication of key findings, we attempted to replicate Boutonnet and Lupyan (2015). We replicated their behavioral findings that response times to indicate whether an auditory cue matches a visual image of an object were faster for match than mismatch trials and faster for linguistic than non-linguistic cues. We did not replicate the main ERP effects supporting a positive effect of linguistic labels on the early perceptual ERP components P1 and P2, though we did find a congruence by cue type interaction effect on those components. Unlike Boutonnet and Lupyan, we found a main effect of cue type on the N4 in which non-linguistic cues produced more negative amplitudes. Exploratory analyses of the unpredicted N4 effect suggest that the response time advantage of linguistic labels occurred during semantic rather than early visual processing. This experiment was pre-registered at https://osf.io/cq8g4/ and conducted as part of an undergraduate cognitive science research methods class at Vassar College.
