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}

For instance, what emotion a presenter focuses on can shape their perception of the overall emotion of the room. 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. Our findings provide very limited evidence for modulations of prediction error signaling by probabilistic expectations as specified in contemporary predictive coding models.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70076"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12090177/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144102531","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}

One proposed measure is the breath-counting task (BCT), which measures how accurately one can count cycles of their breath. Breath counting, which involves sustained attention, meta-awareness, and an internal locus of attention, has been shown in adults to be related to measures of mindfulness even when controlling for established attentional measures. In this study, we test the psychometrics of the BCT in a convenience sample of 78 adolescents with elevated rumination. In preregistered analyses, we related breath-counting measures, including novel objective respiration measures, to a suite of self-report measures as well as the sustained attention to response task (SART). While breath-counting performance showed fair split-half reliability and similar distributions to studies in adults, it did not show the expected positive associations with self-reported mindfulness measures (neither trait nor EMA). Surprisingly, breath-counting accuracy showed negative correlations with a subscale measuring observing of emotions and body sensations, negative correlations with nonreactivity, and performance decrements were larger for individuals scoring more highly on mindfulness in general. The SART showed a small negative correlation with breath-counting resets (an index of mind-wandering). Finally, breath-counting performance was not related to other theoretically relevant clinical, personality, and executive functioning criteria. Our results suggest that, at least in ruminative adolescents, breath-counting may measure a very narrow, contextual form of sustained attention, may not capture other qualities of mindfulness, and may lack predictive validity.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70071"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12053031/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144030783","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}

In this electrophysiological study, we treated word concreteness as a continuous variable and examined its effects on ERPs across three tasks with distinct processing demands (semantic, affective, grammatical). Behavioral results revealed task-dependent concreteness effects: in the semantic task, reaction times were faster for words at both concreteness extremes, and the classical linear advantage emerged for concrete words. Mass univariate ERP analyses revealed distinct spatiotemporal patterns of task-dependent concreteness effects. In the semantic task, we identified three significant clusters reflecting increased parietal N2/P3-like and sustained bilateral fronto-temporal negativity ERPs and decreased central N400-like ERP for abstract words. By contrast, the affective task elicited an increased parietal P600-like ERP for abstract words. Moreover, results from multivariate representational similarity analysis and an intersection analysis revealed that concreteness is encoded in ERP spatiotemporal patterns from 450 ms onwards, regardless of task, suggesting its role not only as an organizational principle in semantic representation, but also as a factor influencing downstream word processing and univariate ERP concreteness effects. Our findings challenge and extend existing theories like the dual coding and context availability ones, highlighting the importance of treating concreteness as a continuous variable and considering task context in word processing studies. This approach, enabled by advanced analytical techniques, provides a more nuanced understanding of how the brain processes and represents words.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 5","pages":"e70074"},"PeriodicalIF":2.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12100582/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144128548","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}
