Mini review: Challenges in EEG emotion recognition

Frontiers in Psychology, Journal Year: 2024, Volume and Issue: 14

Published: Jan. 4, 2024

Electroencephalography (EEG) stands as a pioneering tool at the intersection of neuroscience and technology, offering unprecedented insights into human emotions. Through this comprehensive review, we explore challenges opportunities associated with EEGbased emotion recognition. While recent literature suggests promising high accuracy rates, these claims necessitate critical scrutiny for their authenticity applicability. The article highlights significant in generalizing findings from multitude EEG devices data sources, well difficulties collection. Furthermore, disparity between controlled laboratory settings genuine emotional experiences presents paradox within paradigm research. We advocate balanced approach, emphasizing importance evaluation, methodological standardization, acknowledging dynamism emotions more holistic understanding landscape.

Assessing Trial-by-Trial Electrophysiological and Behavioral Markers of Attentional Control and Sensory Precision in Psychotic and Mood Disorders

Schizophrenia Bulletin, Journal Year: 2024, Volume and Issue: unknown

Published: April 14, 2024

Abstract Background and Hypothesis The current study investigated the extent to which changes in attentional control contribute performance on a visual perceptual discrimination task, trial-by-trial basis transdiagnostic clinical sample. Study Design Participants with schizophrenia (SZ; N = 58), bipolar disorder (N 42), major depression 51), psychiatrically healthy controls 92) completed perception task stimuli appeared briefly. design allowed us estimate lapse rate precision of representations stimuli. Electroencephalograms (EEG) were recorded examine pre-stimulus activity alpha band (8–13 Hz), overall relation behavior task. Results We found that attention was elevated SZ group compared all other groups. also observed differences activity, participants showing highest levels when averaging across trials. However, analyses showed within-participant fluctuations significantly predicted likelihood making an error, Interestingly, our analysis demonstrated aperiodic contributions EEG signal (which affect power estimates frequency bands) serve as significant predictor well. Conclusions These results confirm has been SZ, validate markers their use basis, suggest are important target for further research this area, addition alpha-band activity.

The dynamics of statistical learning in visual search and its interaction with salience processing: An EEG study

NeuroImage, Journal Year: 2024, Volume and Issue: 286, P. 120514 - 120514

Published: Jan. 9, 2024

Visual attention can be guided by statistical regularities in the environment, that people implicitly learn from past experiences (statistical learning, SL). Moreover, a perceptually salient element automatically capture attention, gaining processing priority through bottom-up attentional control mechanism. The aim of our study was to investigate dynamics SL and if it shapes target selection additively with salience processing, or whether these mechanisms interact, e.g. one gates other. In visual search task, we therefore manipulated frequency (high vs. low) across locations while, some trials, terms colour. Additionally, halfway experiment, high-frequency location changed opposite hemifield. EEG activity simultaneously recorded, specific interest two markers related post-selection respectively: N2pc SPCN. Our results revealed both saliency significantly enhanced behavioural performance, but also interacted each other, an attenuated effect at location, smaller for targets. Concerning dynamics, benefit more evident during early stage as indexed larger early-SPCN, whereas modulated underlying neural particularly later on, late-SPCN. Furthermore, showed rapidly acquired adjusted when spatial imbalance changed. Overall, findings suggest is flexible changes and, combined jointly contributes establishing priority.

Common sources of linguistic conflict engage domain-general conflict control mechanisms during language comprehension

Cognitive Affective & Behavioral Neuroscience, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 12, 2025

Abstract The current study tested the hypothesis that lexical ambiguity, a common source of representational conflict during language comprehension, engages domain-general cognitive control processes are reflected by theta-band oscillations in scalp-recorded electroencephalograms (EEG). In Experiment 1, we examined neural signature elicited lexically ambiguous compared to unambiguous words sentence comprehension. results showed midfrontal theta activity was increased response linguistic (lexical ambiguity). 2, postconflict adaptation effects comparing temporarily sentences followed previous instances (other sentences) those low-conflict (unambiguous) sentence. A effect associated with again found such for high-conflict (temporarily ambiguous) sentences. both experiments, facilitated semantic processing also observed came after point conflict, which may reflect downstream “benefit” engagement. Overall, our provide novel insights into neurocognitive mechanisms underlying comprehension and suggest same computations involved nonlinguistic conflict.

A standardized framework to test event-based experiments

Published: April 30, 2024

The replication crisis in experimental psychology and neuroscience has received much attention recently. This led to wide acceptance of measures improve scientific practices, such as preregistration registered reports. Less efforts have been devoted performing reporting the results systematic tests functioning setup itself. Yet, inaccuracies performance may affect a study, lead failures, importantly, impede ability integrate across studies. Prompted by challenges we experienced when deploying studies six laboratories collecting EEG/MEG, fMRI, intracranial EEG (iEEG), here describe framework for both testing setup. In addition, 100 researchers were surveyed provide snapshot current common practices community standards concerning published experiments’ setups. Most reported their Almost none, however, performed test or results. Tests diverse, targeting different aspects Through simulations, clearly demonstrate how even slight can impact final We end with standardized, open-source, step-by-step protocol (visual) event-related experiments, shared via protocols.io. aims benchmark future replications insights into research quality help reproducibility results, accelerate multi-center studies, increase robustness, enable integration
