To construct an updated assessment about the gravitational consequences and change gait patterns accordingly, the central nervous system (CNS) integrates multiple sensorial cues, including vestibular and proprioceptive (i.e., body-based cues) and visual. Not much is known about the contribution of the autonomic nervous system (ANS) to locomotion regulation, especially when multiple types of sensorial cues are involved. Here we examine the responsiveness of the ANS, as reflected by cardiac reactivity, for example heart rate (HR) and heart rate variability (HRV), to coherent versus non-coherent sensorimotor signaling. Fourteen healthy young participants completed level, uphill, and downhill self-paced walking trials in a virtual reality (VR) environment in which the incline of the visual scene was either congruent or incongruent with the physical incline of the walking surface. We found that during level walking, incongruent visual cues (i.e., up/downhill scenery) triggered alterations in ANS balance, reflected in HRV decrease and in a residual increase of HR. Taken together with the fact that an ultimate change in gait patterns requires alterations in cardiac resources, we speculate that ANS function and its responsive modes of action are, in fact, facilitating adaptive behavior.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70072"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12117317/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144161958","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}

Modulations of the N400 generally indicate that while novel metaphors are initially processed as semantic anomalies, after a connection is found relating the concepts, they pattern more with literal sentences. Existing research largely focuses on monolinguals, but less is known about novel metaphor processing in bilinguals' second language (L2). Here, we combine robust single-trial ERPs and behavioral measures to investigate how L2 English users process full-sentence novel metaphors. We compare our results to a previous study with English monolinguals using the same experimental design to test three competing hypotheses: L2 conceptual expansion will be more effortful than, more efficient than, or similar to L1. Group differences suggest more effortful processing for L2 English users than monolinguals. Behaviorally, L2 users show more sentence evaluation errors than monolinguals, particularly for anomalous sentences. ERP results in L2 users reveal an N400 semantic anomaly effect at the sentence-final position, with no significant differences between metaphorical and literal or metaphorical and anomalous sentences. Monolinguals show a graded N400 effect, with significant differences between literal and anomalous as well as metaphorical and anomalous sentences. By comparing L2 users' results with monolingual English users and using naturalistic full-sentence structures, our findings contribute to the emergent literature on L2 novel metaphor processing and conceptual expansion while also unraveling the cognitive challenges associated with incremental processing and integration of L2 metaphorical sentences.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70066"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12063520/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143990627","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}

Through a double-blind crossover study, we investigated the effects of dual-site beta transcranial alternating current stimulation (tACS) over the right inferior frontal gyrus (rIFG) and pre-supplementary motor area (preSMA) on functional connectivity measured with electroencephalography and response inhibition (stop-signal task performance) in 15 older (aged 61-79 years) and 18 young (aged 18-34 years) adults. Two tACS conditions were administered in separate sessions: in-phase tACS, where electrical currents delivered to rIFG and preSMA had a 0° phase difference, and anti-phase tACS, where currents had a 180° phase difference. Resting-state beta band rIFG-preSMA connectivity significantly increased after in-phase tACS for older and young adults and decreased after anti-phase tACS for older adults. Response inhibition significantly improved after both in- and anti-phase tACS for young and older adults. These findings suggest that tACS can potentially modulate rIFG-preSMA connectivity in a phase-specific manner in the aging brain, and that inhibitory performance might not be directly regulated by resting-state rIFG-preSMA phase connectivity. Due to the lack of sham control, placebo effects cannot be ruled out. However, the differing neurophysiological effects from in- and anti-phase tACS suggest that rIFG-preSMA resting-state phase connectivity is unlikely to underpin the changes in inhibitory performance. Future studies incorporating a sham control are required to verify these findings.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70060"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12051364/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996293","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}

Despite existing research, the necessity of consciousness for effective high-level conflict control remains an open question. This study seeks to address this research gap through two subliminal Stroop priming experiments combined with event-related potential measurements, aiming to clarify the brain dynamics of unconscious cognitive control and its influence on subsequent conscious control. The participants were instructed to perform color-naming tasks for supraliminal Stroop or non-Stroop targets following subliminal Stroop or non-Stroop primes. In Experiment 1, the primes also served as targets, whereas in Experiment 2, they did not. In both experiments, prime-locked analyses revealed Stroop effects on N450 amplitudes but not on slow potential (SP) amplitudes. Furthermore, target-locked analysis revealed conflict adaptation effects on SP amplitudes and reaction times; the Stroop effects were smaller following Stroop primes compared with non-Stroop primes. Overall, these findings demonstrate that early-stage unconscious cognitive conflict detection occurs and affects subsequent conscious cognitive control; however, there is insufficient evidence to support unconscious conflict resolution. Our study provides valuable insights into the limits of unconscious processing and highlights the importance of further investigating the deep neural pathways underlying unconscious cognitive conflict processing.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70061"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144050868","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}

In many neurological conditions, from Parkinson's disease to stroke, the voluntary control of SPEM can be compromised. Therefore, SPEMs can serve as sensitive proxies for assessing cognitive and sensorimotor function. Prior research has shown that SPEMs are influenced by attention and working memory load, yet it remains unclear how the sensory modality of concurrent tasks interacts with these effects. Here, we conducted a 3 (working memory load: no load, easy [low load], and hard [high load]) × 2 (sensory modality: visual vs. auditory) experiment to examine how working memory load and secondary task modality interact to affect SPEM in healthy young adults. Participants tracked a moving circle while simultaneously performing an arithmetic task, where they added either constant (1) or variable (1-5) numbers which were presented visually or auditorily. Our results showed that a secondary auditory task increased tracking variability during high cognitive load. In contrast, we found that the visual task improved tracking, reducing variability irrespective of cognitive load. We interpret our results as evidence that auditory processing requires additional top-down control that is critical for the control of smooth pursuit, diverting resources required for smooth pursuit and, consequently, increasing SPEM variability. These findings emphasize the importance of sensory modality in understanding the interactions between working memory and oculomotor control. We suggest that auditory secondary cognitive tasks may provide a more sensitive test of sensorimotor control deficits in future research with clinical populations.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70069"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12051362/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144012392","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}

For this, arterial pressure, sympathetically-mediated cutaneous vasoconstriction and heart rate (HR) were assessed in Wistar rats during a single (acute) or the 10th session of restraint. We found similar cardiovascular responses during the acute session of restraint stress in male and female animals. Cardiovascular habituation was evident as an accelerated HR return to pre-stress parameters during the recovery of the 10th restraint session and was also similar in both sexes. However, repeated restraint facilitated the sympathetically-mediated cutaneous vasoconstriction in females. Aged rats had reduced blood pressure reactivity during the acute restraint session in relation to male adult rats, whereas adolescents exhibited a facilitated HR return to basal parameters during recovery of the acute restraint. Also, adolescent animals had reduced tachycardiac and pressor responses during the 10th session of restraint stress. Taken together, the findings obtained in this study suggest that cardiovascular reactivity during an acute stress session as well as the habituation of tachycardia identified during repeated exposure to this stressor are sex-independent. However, females might present higher vulnerability to homotypic stressors in relation to males as consequence of an enhanced sympathetic reactivity. Regarding the influence of age, aging seems to limit cardiovascular reactivity during acute stress, whereas cardiovascular habituation processes appear enhanced during adolescence.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70062"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144014544","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}

The objective of this meta-analysis was to determine the effect of acute psychological stress on central pulse wave velocity (PWV) compared to pre-stress (baseline) levels in adults free of overt CVD. Electronic databases (PubMed, SPORTDiscus, and Google Scholar) were queried from inception to July 2024. Reference lists of eligible studies and previous relevant reviews were also screened. Studies were included if: (i) a noninvasive measure of PWV was used that included a central (aortic) arterial segment; (ii) participants were adults (≥ 18 years) free of overt CVD; and (iii) the acute stressor was purely psychological in nature. Appraisal and Synthesis Methods: Effect sizes were calculated as standardized mean differences (SMD) and pooled using a random-effects model. The magnitude of effect was adjudicated as trivial (< 0.2), small (0.2), moderate (0.5), or large (0.8). A total of 11,689 studies were identified, from which 7 studies (11 effects, N = 162 participants) were eligible for inclusion. Moderate Acute psychological stress induced a moderate (SMD: 0.51, p < 0.0001; 95% CI: 0.34, 0.68) increase (detrimental) in central PWV, and there was insubstantial heterogeneity between studies (Cochran's Q (10) = 2.62 (p = 0.99)). The small overall number of studies as well as key differences in study methodologies limit the ability to elucidate the magnitude and consistency of stress-induced increases in PWV. Nonetheless, the present findings suggest that acute psychological stress induces significant increases in central PWV among adults free of overt CVD. The acute PWV response to psychological stress likely contributes to elevated CVD risk over time.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70068"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12065061/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143979196","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}

While there is an increasing interest in understanding how endogenous attention affects emotion perception, existing studies have largely focused on single-stimulus perception. There is limited understanding of how endogenous attention influences emotion evidence integration across multiple sources. To investigate this question, human participants (N = 40) were invited to judge the average emotion across an array of faces ranging from fearful to happy. Endogenous attention was manipulated by instructing participants to decide whether the face array was \"fearful or not\" (fear attention), \"happy or not\" (happy attention). Eye movement results revealed an endogenous attention-induced sampling bias such that participants paid more attention to extreme emotional evidence congruent with the target emotion. Computational modeling revealed that endogenous attention shifted the decision criterion to be more conservative, leading to reduced target-category decisions. These findings unraveled the cognitive and computational mechanisms of how endogenous attention impacts the way we gather emotional evidence and make integrative decisions, shedding light on emotion-related decision-making.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70059"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12034915/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144008945","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}

Specifically, observers typically report seeing a stimulus more often during states of weak alpha power, likely due to a shift in detection criterion. However, prior work has paid little attention to the specific stimulus properties mediating detection. In early vision, different stimulus properties are preferentially processed along the magnocellular (MC) and parvocellular (PC) pathways, which vary in their preference for spatial and temporal frequency content and chromatic information. The goal of this study was to understand how spontaneous alpha power affects the detection of stimuli which are preferentially processed by either the MC or PC pathway. To achieve this, we used the \"Steady/Pulsed Paradigm\" which presented a brief, near-threshold stimulus in two conditions intended to bias processing to one or the other pathway. Our results showed an interaction effect of pre-stimulus alpha power on detection between the two conditions. While weak alpha power was predictive of seeing the stimulus in the steady condition (MC-biased), no significant effect was found in the pulsed condition (PC-biased). This interaction was driven by a selective alpha-related criterion shift in the steady condition, with no effect of pre-stimulus alpha on sensitivity (d') in either condition. Our results imply that alpha oscillations may differentially regulate excitability in the MC and PC pathways.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70070"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12056284/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030786","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}

This knowledge allows us to form expectations about future sensory events. Several influential predictive coding models posit that, when a stimulus matches our expectations, the activity of feature-selective neurons in the visual cortex will be suppressed relative to when that stimulus is unexpected. However, after accounting for known critical confounds, there is currently scant evidence for these hypothesized effects from studies recording electrophysiological neural activity. To provide a strong test for expectation effects on stimulus-evoked responses in the visual cortex, we performed a probabilistic cueing experiment while recording electroencephalographic (EEG) data. Participants (n = 48) learned associations between visual cues and subsequently presented gratings. A given cue predicted the appearance of a certain grating orientation with 10%, 25%, 50%, 75%, or 90% validity. We did not observe any stimulus expectancy effects on grating-evoked event-related potentials. Multivariate classifiers trained to discriminate between grating orientations performed better when classifying 10% compared to 90% probability gratings. However, classification performance did not substantively differ across any other stimulus expectancy conditions.
