We investigated whether event-related potentials (ERP) related to the visual processing of facial expressions are modulated by participants' perceived arousal and valence at the stimulus level. ERPs were recorded while participants (N = 80) categorized the gender of faces expressing fear, anger, happiness, and no emotion. Participants then viewed each face again and rated them on arousal and valence using 1-9 Likert scales. For each participant, ratings of each unique face were linked back to corresponding ERP trials. ERPs were analyzed at all time points and electrodes using hierarchical mass univariate statistics. Three different ANOVA models were employed: the original emotion model, and models with valence or arousal ratings as trial-level regressors. Results from models with ratings highly overlapped with the original model, although they were more temporally restricted. The N170 component was the most impacted by arousal and valence ratings, with four out of six emotion contrasts revealing significant valence or arousal interactions. Emotion effects on the P2 component were mostly unrelated to ratings. On the EPN component, only two contrasts related to both arousal and valence ratings. Thus, ERP emotion effects are related to participants' perceived arousal and valence of the stimuli, although this association depends on the contrast analyzed. These findings, their limitations, and generalizability are discussed in reference to existing theories and literature.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70045"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11926668/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143670859","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}

However, evidence for the LC-NA hypothesis is mixed, and investigations in different sensory modalities are lacking. This study investigated whether continuous taVNS enhances standard NA markers along with neural processing in three sensory modalities (auditory, respiratory, and somatosensory). In a 2-day Sham-controlled crossover protocol, 45 healthy adults received taVNS at the cymba concha and Sham stimulation at the earlobe. During stimulation, participants experienced paired auditory clicks, inspiratory occlusions, and electrocutaneous stimuli, while EEG was acquired. Salivary alpha-amylase (sAA) and subjective experienced arousal were measured at pre-/end-stimulation. Resting-state EEG was measured pre-/poststimulation to assess alpha-band (8-13 Hz) oscillation power, and participants rated the intensity and unpleasantness of all stimuli. Auditory-, respiratory-related-, and somatosensory evoked potentials were measured, specifically P50, N1, and P2 components, as well as the P50/N1 amplitude difference of the second and the first stimulus in the pair (neural gating; S2-S1). Although no effects in P50 or N1 amplitudes were observed, P2 amplitudes in auditory and somatosensory blocks increased during taVNS. Self-reported arousal increased in the taVNS condition, with no effects on neural gating, sAA concentration, or resting-state alpha power. taVNS had no effect on self-reported intensity/unpleasantness of stimuli. These results highlight certain limitations posed by combining taVNS and EEG and underline the need for further mechanistic taVNS research.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70048"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143701354","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}

We used the reading version of the flankers task in which participants had to classify foveal target words as either being a noun or an adjective. In Experiment 1, targets were flanked by either syntactically congruent or incongruent words (e.g., noun noun noun vs. adjective noun adjective), or were embedded in a sequence of words that was either grammatical or ungrammatical (e.g., adjective noun verb vs. verb noun adjective). Experiment 2 employed the same stimuli as the latter condition, with participants now tasked to judge the word sequence as being grammatically correct or not. Results showed a significant reduction in N400 amplitude for both the syntactically congruent and syntactically grammatical conditions in Experiment 1, and for syntactic grammaticality when making sentence judgments in Experiment 2. In the second experiment, a syntactically grammatical word sequence could be reliably decoded starting around 500 ms post-stimulus onset. These results indicate that skilled readers can extract and process syntactic information from multiple words in a short timeframe and that syntactic categories retrieved from individual words (i.e., parts-of-speech) are rapidly integrated into a sentence-level representation.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70019"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543207","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}

Here, we aimed to conceptually replicate and extend these findings by investigating the effects of different time-dependent taVNS stimulation protocols. In Study 1, an identical paradigm to our previous study was employed with interval stimulation (30-s on/off). Participants viewed unpleasant and neutral scenes on two consecutive days while receiving taVNS or sham stimulation and completed a recognition test 1 week later. Replicating previous results, unpleasant images encoded under taVNS, compared to sham stimulation, elicited larger amplitudes in an earlier window of the LPP during encoding, as well as more pronounced late Old/New differences. However, no effects of taVNS on memory performance were found. In Study 2, we followed up on these findings by synchronizing the stimulation cycle with image presentation to determine the taVNS effects for images encoded during the on and off cycles. We could replicate the enhancing effects of taVNS on brain potentials (early LPP and late Old/New differences) and found that taVNS improved recollection-based memory performance for both unpleasant and neutral images, independently of the stimulation cycle. Overall, our results suggest that taVNS increases electrophysiological correlates of emotional encoding and retrieval in a time-independent manner, substantiating the vagus nerve's role in emotional processing and memory formation, opening new venues for improving mnemonic processes in both clinical and non-clinical populations.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70034"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894791/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143606088","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}

Previous studies indicate that physiological synchrony may arise during nonverbal interactions.

In this work, we examined heart rate synchrony during a cooperative joint action task, exploring how task constraints, novelty, and behavioral synchrony influence physiological alignment. To achieve this, we periodically modulated task demands by alternating between peer-to-peer and leader-follower dynamics, as well as between complementary and imitative movements, and their combinations. Additionally, we assessed the role of individual differences by examining the impact of dyad members' Social Anxiety and Perspective Taking levels. We further investigated how task demands and personal traits shape the perceived quality of social interactions and subject-level heart rate variability. Our findings revealed a significant increase in physiological synchrony and a decrease in perceived interaction quality when participants switched to a novel task version (i.e., during switch blocks) compared to task repetition. Task switching was also associated with increased heart rate variability. Notably, Social Anxiety negatively predicted physiological synchrony, suggesting that more socially anxious dyads were less likely to achieve physiological alignment. However, no relationship was observed between physiological synchrony and task performance. Overall, our results suggest that physiological synchrony intensifies when dyads navigate the challenge of learning a novel task together, and that both contextual and individual aspects contribute to its emergence.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70031"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11913774/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143650084","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}

Participants were exposed to either attachment security primes (N = 28) or control primes (N = 29) and then completed a gambling task while connected to an electroencephalogram system. We anticipated that attachment security priming would affect risky decision-making at both the behavioral and neural levels. Feedback-related negativity (FRN) and P3 components were analyzed. At the behavioral level, participants in the attachment security priming group selected less risky choices than those in the control group. At the neural level, participants exposed to attachment security primes exhibited attenuated FRN but no significant difference in P3 amplitude. The regression analysis showed that small P3 amplitude predicted large risk-taking tendencies in the control priming group, whereas P3 amplitude did not significantly predict risk-taking tendencies in the attachment security priming group. These findings suggest how boosted attachment security affects economic risky decisions: It lowers people's affective reactions to undesirable outcomes and buffers people's underestimation of the outcome salience. Specifically, attachment security seems to attenuate risk-taking by preventing people from down playing the significance of outcomes. Our findings extend existing knowledge by demonstrating attachment security priming ability to reduce risk-taking tendencies beyond naturalistic to economic decisions.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70010"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143597452","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 ethology, animals exhibit reduced fear responses while habituating to repeated threatening stimuli. It remains unclear whether pain habituation in humans involves a fear reduction mechanism. In an fMRI experiment, we investigated pain-related brain responses before and after the development of habituation to pain induced by repetitive painful stimulation in healthy adults. In another behavioral experiment, we examined emotional responses in another group of healthy adults to assess pain habituation-related emotional changes. Pain habituation at the repetitively stimulated forearm site entailed reduced fear and engaged the neural system implicated in fear reduction, which included the amygdala, anterior cingulate, and ventromedial prefrontal cortex (vmPFC). Individual pain-related fear, assessed via a questionnaire, predicted neural activity within the periaqueductal gray (a pain-modulating center), which covaried with vmPFC responsivity. Moreover, pain habituation also occurred at nonstimulated sites, and its extent was predicted by habituation at the repetitively stimulated site. This phenomenon again involved the vmPFC, which has also been implicated in safety generalization under threat. These results suggest a role of fear reduction in pain habituation that is related to individual pain fearfulness. The reduced fear acquired at the repetitively stimulated site can be generalized to other body parts to cope with similar aversive situations. The identified link between fear and pain habituation helps explain why impaired fear reduction and reduced pain habituation coexist in chronic pain conditions.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70039"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543206","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 specific facets of cognitive control affected by a scarcity mindset and the underlying mechanisms driving this effect remain not fully understood. Based on the dual mechanisms of control framework, this study examines the effects of a scarcity mindset on both proactive and reactive control (Experiment 1) and explores the underlying mechanisms (Experiment 2). Eighty-nine participants (39 in Experiment 1 and 50 in Experiment 2) were assigned to either a scarcity or neutral mindset and completed cognitive tasks while their event-related potentials (ERP) were recorded. Experiment 1 used an AX Continuous Performance Task (AX-CPT) to distinguish between proactive and reactive control. Results indicated that a scarcity mindset selectively weakened proactive control, as evidenced by weaker proactive control indicators (i.e., P3b), without affecting reactive control. In Experiment 2, we adjusted task cue availability before or after target onset in a cued-flanker task to manipulate the potential for proactive control. We found that the weakened proactive control observed in individuals with a scarcity mindset could be attributed to lowered motivation rather than impaired cognitive ability. Collectively, these findings provide valuable insights into how mindset influences cognitive control and offer promising implications for designing effective interventions to mitigate the negative impact of a scarcity mindset.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70001"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143586682","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}

We investigated the acute effects of aerobic exercise on risky decision making, its underlying neurocognitive processes (i.e., reward processing) and response inhibition. 33 female and 27 male participants (aged 24.0 ± 2.9 years) were randomly allocated to an intervention group, who performed 20 min of moderately-intense running on a treadmill, and a control group, who watched a video. Before and after these sessions, a Go/NoGo task and an Iowa Gambling task were administered. The feedback-related negativity (FRN) and P300 elicited by wins and losses during gambling were recorded with electroencephalography. We found no group differences in pre- to posttest changes in performance on the Go/NoGo task and Iowa Gambling task. However, there was a greater increase in the bias for infrequent losses in the intervention compared to the control group, accompanied by a change towards higher P300 amplitude and lower negativity of the FRN. In conclusion, an exercise session did not affect performance on cool and hot executive function tasks but altered the strategic approach in decision making. Exercise led to a better anticipation of outcomes of decisions and a higher maintenance of the feedback significance, which both contributed to a change towards choices that yield less frequent, larger losses.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70029"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143543195","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}

A recent study, showing images of facial attractiveness, however suggests the existence of valence-related effects at very long latencies (1000-3000 ms post stimulus). This could offer new insights into the time-course of affective neural processing. Yet, it remains unclear whether the long-latency effect was specific to facial attractiveness, or to valence in general. To corroborate the existence of a long-latency valence effect, we presented distinctly positive, neutral, and negative valenced IAPS images to a large sample of 224 participants while recording their electroencephalogram (EEG). Larger ERP amplitudes were elicited by both positively and negatively valenced compared to neutral stimuli (an affective salience effect) from roughly 500 until 1300 ms, followed by an ordered valence effect of larger amplitudes to negatively compared to positively valenced images from 1500 until 2500 ms. These findings corroborate the previously observed sequence of an affective salience effect followed by a long-latency valence effect. However, the polarity of this valence effect was reversed from that of the facial attractiveness study. Allostasis is discussed as potential reconciling factor. Effects in the N2 and P300 components were also found, but could not be clearly labeled as an affective salience or a valence effect. These results fit with two-stage emotion theories such as the theory of constructed emotions.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 3","pages":"e70030"},"PeriodicalIF":2.9,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11894780/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143605930","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}
