Using the picture-word interference (PWI) task, these studies have found behavioral evidence of interference effects (i.e., slower and/or less accurate responses) but ERP evidence of typical priming (i.e., smaller N400s) when to-be-named pictures are presented with semantically related words. To address these seemingly contradictory results, we performed a semantic PWI experiment with two modifications from the typical design. First, we implemented a novel behavior-contingent analysis of semantically related word-picture pairs in which single-trial ERP data were reaveraged for word-picture pairs that either showed a facilitation pattern or an inhibition pattern (faster or slower RTs for related than unrelated pairs). Second, we extended the ERP analysis epoch to latencies not typically analyzed in previous studies due to concerns about speech artifact. In the behavioral contingent averaged ERPs, the \"facilitation bins\" produced typical priming in early (200-400 ms) and late (400-600 ms) N400 epochs, while the \"inhibition bins\" produced reversed priming (greater negativity for related than unrelated prime words) in the late N400 epoch. In addition, after correcting for speech artifact, we observed reversed priming for the semantic condition in a later epoch (700-1200 ms). Together, these results help resolve the apparent conflict between neural and behavioral responses in the PWI paradigm and suggest a way forward in using response-contingent averaging of ERP data in language production.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 10","pages":"e70158"},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145192719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the mechanisms behind the EEG changes targeted by EEG-NF remain unclear. The present study addresses this gap by examining methodological issues in the assessment of spontaneous EEG changes during EEG-NF sessions. Over multiple trials, healthy young adults observed a gray circle that either remained constant (control condition) or was continuously modified in size at different frequency rates (1, 5, and 10 Hz). We investigated whether EEG frequency bands classically targeted by EEG-NF: (i) change spontaneously over time, (ii) are influenced by a continuously modified visual stimulus, and (iii) the frequency at which this stimulus is modified. Results revealed: (i) a spontaneous increase in alpha power throughout the entire task, (ii) an increase in theta power when exposing participants to a continuous modification of the visual stimulus (relative to perceiving the same unmodified stimulus), and (iii) an absence of changes in the EEG frequency bands studied when manipulating the frequency of stimulus modification. These findings suggest that the EEG changes observed during EEG-NF are influenced by the task environment itself and not only by successful EEG self-modulation. It is therefore crucial to carefully design EEG-NF protocols to account for non-specific effects and ensure that observed EEG changes are due to the hypothesized mechanisms. Further research is needed to delineate the mechanisms underlying EEG modulation in EEG-NF and to refine protocols prior to clinical application.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 10","pages":"e70163"},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12495449/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145225491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we provide a first demonstration of whether the physiological changes associated with a single IH session provide a transient post-intervention EF benefit. Healthy young adults (N = 24) completed an IH protocol entailing 12 alternating 5-min normoxic (P_ETO₂ = 100 mmHg) and hypoxic (P_ETO₂ = 50 mmHg) intervals that were normocapnic and isocapnic, and on a separate day completed a time-matched normoxic control protocol.

Antisaccades require a goal-directed eye movement (i.e., saccade) mirror-symmetrical to a target and provide the resolution to detect subtle EF changes. As expected, hypoxic intervals decreased arterial and cerebral tissue O₂ saturation and increased CBF as estimated via near-infrared spectroscopy and transcranial Doppler ultrasound (ps < 0.001). In turn, antisaccade reaction times (RT) did not differ between T0 and T1 (p = 0.29); however, at T2 a reliable RT reduction was observed (p = 0.004). Notably, cortical hemodynamic changes during the hypoxic intervals did not correlate with the antisaccade RT benefit observed at T2 (ps > 0.17).

This suggests that response times reflect the differential functioning of an early process involving global motoric inhibition, observed in ITs, and a later process involving competitive inhibition between response options, observed in MTs. In this study, we sought to link the behavioral and neural dynamics of cognitive control in the flanker task by combining electroencephalography (EEG) with a button release-and-press method that allows for response times to be separated into ITs and MTs. Crucially, this method enabled the examination of initiation-locked event-related potentials (ERPs) in addition to traditional stimulus-locked ERPs. We observed candidate neural correlates of the early global and later competitive inhibitory processes, in early parietal and later central activity respectively. Exploratory cluster-based permutation analyses further supported traditional ERP analyses, providing more precise estimates of the onset and offset of effects underlying the congruency sequence effect. This work indicates that the component processes underlying cognitive control which generate dissociable patterns of effects in ITs and MTs may also generate dissociable patterns of effects in neural measures. Critically, initiation-locked analyses revealed a clearer dissociation of the patterns of effects underlying specific ERP components and shed new light on findings from standard stimulus-locked analyses.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 10","pages":"e70159"},"PeriodicalIF":2.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145244939","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the neural level, processing irony has been associated with activity in the medial prefrontal cortex, inferior frontal gyrus (IFG), posterior superior temporal gyrus (pSTG), precuneus, and inferior parietal lobule, among others. The objective of this study was to examine the cognitive processes and the neural correlates of processing irony in Mexican adults using a novel task designed for Spanish-speaking individuals. A total of 45 participants completed a cognitive assessment and performed a contextual discrepancy task while undergoing functional magnetic resonance imaging. With the lowest classification accuracy and the slowest response times, the results showed processing irony to be challenging. As expected, processing irony engaged brain regions primarily associated with ToM (e.g., precuneus) and language processing (e.g., IFG and pSTG). In contrast, the identification of literal and unrelated statements activated motor-related areas. Interestingly, no differential activation was found for the processing of white lies.

Specifically, our findings corroborate that erroneous responses come with significantly shortened response durations (RDs) compared to correct responses, pointing to an immediate and active cancellation of ongoing motor activity. Crucially, ERN amplitude and latency varied with RDs, indicating that the ERN may reflect not only passive error detection but also the autonomous implementation of corrective behavior.

However, amplitude measurements do not fully capitalize on the high temporal resolution of EEG. Specifically, amplitude does not reflect the rate of change in the LPP over a window of interest, which may be important to understand LPP dynamics in individuals with GAD. Indeed, this rate of change of the LPP (i.e., LPP slope) may reflect attentional orienting. The current study leveraged multilevel models to examine the LPP in relation to GAD symptoms. We hypothesized that more-positive LPP slopes to threat images will be associated with GAD symptoms from 400 to 700 ms. Participants (N = 105) passively viewed blocks consisting of threatening or neutral images during EEG recording. Participant-level LPP slopes were estimated using and extracted from multilevel models, and the extracted slopes were examined. LPP slopes were reliable, but they only weakly correlated with mean amplitudes-suggesting LPP slopes may capture an attentional process that could be distinct from that captured by mean amplitudes. When considered as concurrent predictors of GAD, in an early window of the LPP (400-700 ms), the conjunction of the threat-LPP slope and the threat-LPP mean amplitude explained three times as much variance in GAD symptoms as mean amplitude did alone. During a later window of the LPP (700-2000 ms), more-negative LPP slope responses to threat were also related to GAD symptomology. Sensitivity analyses demonstrated that the relationship between the threat-LPP slope and GAD symptoms was largely robust to measurement confounds. Together, the current study is the first to identify that LPP slope is uniquely related to GAD symptoms.
