These rhythms provide a foundation for the brain network interactions required for cognition. Oscillations coexist with non-rhythmic background aperiodic activity that forms a characteristic 1/f pattern in power spectra. Aperiodic brain activity is associated with cognition and can confound the detection of oscillations. In this Registered Report, we applied time-resolved spectral parameterization to EEG recordings during two common cognitive tasks. Neural dynamics recorded during many cognitive paradigms show similar patterns, including synchronization of mediofrontal theta (4-8 Hz) and desynchronization of posterior alpha (9-13 Hz) and central beta (15-30 Hz). Our results indicate that common task time-frequency signatures, including mediofrontal theta synchronization and parietal alpha desynchronization, can be attributed primarily to neural oscillatory phenomena. Intriguingly, we uncover evidence of stimulus-locked aperiodic power changes, which are responsive to the need for cognitive control and to reinforcement processing. Furthermore, aperiodic power correlated strongly with non-baseline-corrected total power estimates, and whereas oscillatory power correlated strongly with portions of baseline-corrected power estimates, it failed to correlate with other portions of baseline-corrected power. Finally, after baseline correction, aperiodic correlations with TF power remain high. These results indicate two primary outcomes. First, task TF signatures in theta and alpha bands reflect primarily parameterized oscillations. Second, aperiodic activity is time-dependent during cognitive processing, and these dynamics are not accounted for by baseline correction.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 6","pages":"e70073"},"PeriodicalIF":2.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12134716/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144216724","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}

We investigated different coping responses after ostracism and explored whether these were preceded by unique facial thermal signatures, reflecting autonomic nervous system (ANS) activity.

Coping after ostracism was assessed during a hypothetical Allocation Game, where participants could do nothing (withdrawal), reduce (antisocial), or increase (prosocial) the hypothetical earnings of their ostracizer. Contrary to expectations, most participants chose to withdraw (52%), with fewer opting for antisocial responses (30%) or prosocial responses (18%) after ostracism. Results from linear mixed-effects modeling revealed that substantial temperature variability occurred only in the nose region of the face. Both ostracism and inclusion showed a decrease in nasal temperature relative to baseline, but the average drop was greater during inclusion, suggesting stronger ANS activation during inclusion rather than ostracism. Crucially, exploratory findings showed that only participants who responded antisocially after ostracism exhibited steeper decreases in nasal temperature during ostracism compared to inclusion. This pattern suggests greater physiological reactivity among antisocial responders, particularly in contrast to those who chose to withdraw.

We found evidence that weaker electrodermal conditioning when the unconditioned stimulus (US) is a film clip is unlikely to be due to trace conditioning, as no prominent delayed unconditioned responses occurred during the film clip after conditioned stimulus offset. We also found that some film clips elicit unique unconditioned responses, which may depend on the specific timing of the most aversive events within each clip. Finally, we found evidence that larger skin conductance responses during the presentation of one of the four trauma film clips used was associated with more frequently reported intrusive memories. This data provides important new information supporting the idea that skin conductance responses during conditioning using electric shock USs might not reflect purely anticipatory fear, at least in the way conceptualized in the literature.

In this study, using electroencephalography (EEG), we examined the neural mechanisms underpinning NSSI and the impact of mindfulness interventions by analyzing brain activity before, during, and after a 10-min brief breath-focused meditation session in adolescents with NSSI. We demonstrate that adolescent NSSI patients show a lower correct rejection rate and sensitivity in an emotional go/no-go task that reflects deficits in cognitive control compared to healthy controls, along with reduced P3 amplitude and theta power. A brief deep breath meditation intervention, but not natural breath meditation intervention, restored the decreased no-go theta power in NSSI patients. Analysis of microstates and neural network of resting-state EEG during meditation showed that properties of microstate D reflecting activation of the attention network differed between intervention strategies and predicted NSSI remission at 1-month follow-up.

To investigate this, we presented double-digit numbers in three tasks designed to target different types of information: a matching task requiring access only to number form, a divisor task situating numbers in the context of basic arithmetic, and a quantifier task using numbers to represent everyday quantities. We measured event-related potentials (ERPs), focusing on the N400 component, which has been linked to access from long-term semantic memory, and looking at the impact of repetition as an implicit probe of facilitated knowledge retrieval. Our results revealed reliable N400 repetition effects for numbers across all tasks, suggesting that numbers are linked to associated representations of numerosity in a relatively automatic manner, using similar mechanisms as the access of semantics from words and pictures. However, consistent with claims that representations of numerosity involve different brain networks compared to general semantics, the scalp distribution of the N400 repetition effect for numbers, which was consistent across our three tasks, differed from that to words in the present experiment and from that observed in prior work using numbers to access general semantics.</p>","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":"62 6","pages":"e70082"},"PeriodicalIF":2.9,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12131122/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144209342","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, little is known about whether physiological responses, particularly pupil size, can implicitly track causality perception. This study employed pupillometry across three experiments to investigate the relationship between pupil dynamics and causality perception. The results revealed that spatiotemporally contiguous launching events (i.e., direct launching), perceived as a causal collision between two objects, induced greater pupil dilation after the collision than simple single-object motion (i.e., passing and pass-by events) or motion with a temporally inverted cause-effect order (i.e., temporal-inverted events), both of which lacked a causal structure. However, launching with a spatial gap (i.e., gap launching) also elicited pupil dilation comparable to direct launching, although gap launching was rated lower in perceived causality. Temporal-inverted events provoked early pupil dilation, corresponding to the sudden and spontaneous motion of the first object. Furthermore, for invariant visual stimuli that could be perceived as either causal launching or noncausal passing (i.e., ambiguous events), pupil size changes did not differentiate between subjective causal and noncausal judgments. These findings indicate that although pupil dilation was evident during causality perception, it was not uniquely or directly tied to causality perception but was influenced by multiple factors, particularly responses to spontaneous motion.

However, the effects of anodal tPCS (a-tPCS) at low frequencies remain unexplored. This study aimed to investigate the a-tPCS effects at 0.5, 1, 3, and 5 Hz on cortical outcomes and its adverse side effects. This double-blinded, randomized, counterbalanced crossover trial included 18 healthy young participants who completed five experimental sessions with 2 mA of a-tPCS for 20 min in a randomized order of frequencies (0.5, 1, 3, and 5 Hz). Single-pulse and paired-pulse transcranial magnetic stimulation (TMS) on the left primary motor cortex (M1) was delivered before and immediately after the stimulation at rest. Sessions were spaced at least 48 h apart to minimize carry-over effects. The results indicated that a single session of a-tPCS at frequencies of 1, 3, and 5 Hz significantly (p < 0.05) enhanced corticospinal excitability (CSE), while 0.5 Hz decreased CSE compared to sham stimulation. The CSE changes at 1 and 5 Hz were associated with increased intracortical facilitation (ICF), with reduced adverse effects observed at higher frequencies. In contrast, the cortical effects of 0.5 Hz were linked to increased short intracortical inhibition (SICI) with minimal side effects. However, all frequencies except 0.5 Hz were associated with phosphenes or flashing lights during stimulation. Given the similar effects of a-tPCS with other pulsatile current stimulation, it is plausible that tPCS could serve as a complementary or superior alternative to TMS, particularly for at-risk and diverse patient populations. However, this claim needs further comparative studies before suggesting clinical superiority for epilepsy and neuro-rehabilitation. Furthermore, like other neuromodulation techniques, tPCS shows potential as an affordable, home-based treatment option.

Conditions included singing, swaying, responding to a virtual conductor of variable expressivity, having your own body movements mirrored by a virtual agent, and combinations thereof. Results showed an inverse relation of turbulence intensity in the alpha range to both degree of movement and perceived level of task emotionality, which was also true for the high gamma range, but to a lesser extent. When factoring in task demand, the effect of level of emotionality in the alpha range deteriorated. This is physiological evidence for why physical arousal is likely to increase the level of perceived emotional engagement or even be misinterpreted as such.
