Using a cross-task paradigm in which a flanker task was interleaved with a language-switching task trial-by-trial, the present study examined the performance of unbalanced Chinese-English bilinguals on a flanker task in forced, voluntary, and natural switching contexts. The cross-domain interaction on the P3 component revealed an atypical flanker effect in forced switching contexts only, and the P3 amplitude of incongruent trials in forced switching contexts was smaller than in both natural and voluntary switching contexts. Furthermore, robust brain-brain and brain-behavior relationships between language control and domain-general control emerged in the forced switching context only. Altogether, our findings support the dynamic adaptation of language control to cognitive control and highlight the importance of different types of switching contexts.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14736"},"PeriodicalIF":2.9,"publicationDate":"2024-11-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142755204","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}

With an increased interest in resting EEG as a potential biomarker for neurocognition, it is paramount that resting EEG findings are reliable and reproducible. One of the major threats to replicability and reproducibility stems from variations in preprocessing and analysis. One of the primary challenges facing the field of developmental EEG is that it can be challenging to acquire data from infants and children, which commonly makes data cleaning and analysis difficult and unstandardized. The goal of the present manuscript is to take a state of the field of the methods experts in resting EEG report they would use to clean and analyze a hypothetical data set. Here we report on the responses of 66 self-identified experts in developmental psychophysiology, none of which submitted identical preregistrations. As expected, there were areas of more and less consensus, but ultimately, we believe our findings highlight opportunities for core methodological work and field-level efforts to establish consensus.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14733"},"PeriodicalIF":2.9,"publicationDate":"2024-11-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142732193","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, improvised actions may affect this coupling differently from predetermined actions. This study used two-person EEG to examine how pianists responded to altered pitch feedback to their own or their partner's actions while they alternated scores or improvised melodies. Feedback-related negativity (FRN) response for self-action was greater in scored than improvised conditions, indicating the enhanced action encoding by playing the score. However, subsequent P3a and P3b responses for self-action were not different across score and improvisation. Further, the P3b response was greater when the two pianists exchanged similar types of melodies (i.e., both improvised or both scores) compared with different types of melodies, suggesting that later cognitive processes may be associated with the task relevance or level of jointness. The presence of the FRN and P3 complex in self-generated improvised action points to the dynamic nature of performance monitoring even without preconceived action plans. In contrast, the FRN and P3 complex in partner-generated improvised actions were subdued compared to the baseline, likely due to the unpredictable nature of the improvised actions of others. Finally, we found a tendency that higher trait empathy was associated with smaller self-action FRN, possibly implying musicians' prioritization of joint goals. Overall, our results suggest that improvisation in a musical turn-taking task may be distinct from score-playing for the earlier processes of performance monitoring, whereas later processes might involve updating a joint representation of the musical context.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14704"},"PeriodicalIF":2.9,"publicationDate":"2024-11-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142668768","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}

Using psychophysical assessments, we compared 31 expert meditators with 33 matched controls (non-meditators who engage in regular reading, more than 5 h per week) in terms of somatosensory accuracy with a somatosensory signal detection task (SSDT) and interoceptive sensibility via self-report measures. We hypothesized that meditators would demonstrate superior somatosensory accuracy, indicative of heightened body awareness, potentially linked to increased alpha modulation in the somatosensory cortex, as observed via electroencephalography (EEG). In the SSDT, participants attempted to detect near-threshold tactile stimuli presented with a non-informative light in half of the trials. Contrary to our expectations, the findings showed that meditators had a lower decision threshold rather than higher accuracy. EEG results corroborated earlier research, indicating reduced prestimulus alpha power in meditators, suggesting enhanced alpha modulation. Furthermore, a trial-by-trial analysis revealed a negative correlation between prestimulus alpha activity and tactile perception. Compared to controls, meditators also reported greater interoceptive sensibility, less emotional suppression, and fewer difficulties in describing feelings. These findings may imply that enhanced tactile perception is associated with lower prestimulus alpha activity by reducing sensory filtering in the somatosensory cortex, thus increasing response rates without necessarily improving accuracy among meditators.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14712"},"PeriodicalIF":2.9,"publicationDate":"2024-11-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142668767","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}

Physiological signal recordings from 40 MDD patients and 40 healthy controls were collected in a baseline stage, in a stress-inducing stage using two cognitive tests, and in the recovery period. Several features were extracted from electrocardiography, photoplethysmography, electrodermal activity, respiration, and temperature. Differences between values of these features under different conditions were used as indexes of autonomic reactivity and recovery. Finally, a linear model was designed to assess MDD severity, using the Beck Depression Inventory scores as the outcome variable. The performance of this model was assessed using the MDD condition as the response variable. General physiological hyporeactivity and poor recovery from stress predict depression severity across all physiological signals except for respiration. The model to predict depression severity included gender, body mass index, cognitive scores, and mean heart rate recovery, and achieved an accuracy of 78%, a sensitivity of 97% and a specificity of 59%. There is an observed correlation between the behavior of the autonomic nervous system, assessed through physiological signals analysis, and depression severity. Our findings demonstrated that decreased autonomic reactivity and recovery are linked with an increased level of depression. Quantifying the stress response together with a cognitive evaluation and personalization variables may facilitate a more precise diagnosis and monitoring of depression, enabling the tailoring of therapeutic interventions to individual patient needs.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14729"},"PeriodicalIF":2.9,"publicationDate":"2024-11-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142648932","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}

Behavioral results showed that disadvantage led to increased risk-taking. Event-related potential data analyses showed, in the parallel comparison condition, a significantly larger Feedback-Related Negativity (FRN) was induced by the self's safe decision than the risky decision and by loss rather than gain. However, in the upward and downward comparison conditions, larger FRN emerged solely in response to the loss of risky rather than safe decisions. On the P3 component, participants in the upward comparison condition showed no significant difference in response to their gain or loss, while the other two conditions did. The highest P3 amplitude, delta/theta power, and aperiodic activity were found in the closely matched condition.

Numerous event-related potential studies have shown that the early posterior negativity (EPN) and the late positive potential (LPP) are larger for high than low arousing emotional pictures. The group approach has been recently extended to the study of the individual case. Usually, many exemplars are used to represent an emotion category. Determining how many pictures are needed to reliably assess affective stimulus evaluation processes at the individual level is crucial when moving toward the goal of exploring idiosyncratic emotional stimuli. Accordingly, in the present study (N = 16), singular images displaying erotic, neutral, and mutilation content were shown 800 times while dense sensor EEG was recorded. At the group level, enhanced EPN and LPP amplitudes for high compared to low arousing stimuli emerged. At the single subject level, significantly larger amplitudes to the erotic than neutral image were observed in 15 out of 16 tests for the EPN and LPP components. Regarding the mutilation image, 15 participants showed a significant EPN effect, while the LPP effect was only found in 10 cases. Notably, emotional modulation of the EPN and LPP was stable over time. The present study contributes to the development of experimental designs tailored to the needs of the case-by-case approach. Since the process of affective stimulus evaluation is considered as a process common-to-all, the use of a singular stimulus exemplar may prove useful to investigate the idiosyncratic nature of emotion.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14718"},"PeriodicalIF":2.9,"publicationDate":"2024-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142626694","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}

To better understand the neural mechanisms underlying IR, we assessed the immediate and lasting effects and their associations with imagery tendency by using unpleasant pictures depicting child maltreatment within a population with childhood maltreatment (CM) history. Participants (n = 68) were instructed to engage in two experimental phases while electroencephalogram was recorded. In the rescripting phase, participants viewed neutral or unpleasant pictures and then either imagined the same pictures or rescripted unpleasant ones to assess immediate effect. In the re-exposure phase, participants passively viewed all pictures without instruction to assess lasting effect. Participants rated their subjective valence and imagery vividness in the rescripting phase or intensity of negative feelings in the re-exposure phase. IR led to an attenuation of the late positive potential (LPP) amplitude in the late time window (2000-6000 ms at parietal-occipital electrodes) and a decrease in self-reported unpleasantness during the rescripting phase. After 5-min interval, unpleasant pictures with rescripted history elicited smaller LPP (400-1500 ms at centro-parietal electrodes) and negative feelings than those with imagery history in the re-exposure phase. The higher habitual use of imagery was associated with a greater reduction in late LPP during the rescripting phase and full-time range LPP during the re-exposure phase. The current findings suggest that IR has an immediate effect and a lasting effect on subjective and neural response in the CM population. Individuals with higher imagery tendency are likely to profit more from IR.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14717"},"PeriodicalIF":2.9,"publicationDate":"2024-11-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142569171","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 machine learning approaches designed for complex, high-dimensional data sets, to predict variation in instantaneous heart period (the inter-heartbeat-interval) from whole-brain hemodynamic signals measured by fMRI. Task-based and resting-state fMRI, as well as peripheral physiological recordings, were taken from two data sets that included extensive repeated measurements within individuals. Our models reliably predicted instantaneous heart period from whole-brain fMRI data both within and across individuals, with prediction accuracies being highest when measured within-participants. We found that a network of cortical and subcortical brain regions, many linked to visceral motor and visceral sensory processes, were reliable predictors of variation in heart period. This adds to evidence on brain-heart interactions and constitutes an incremental step toward developing clinically applicable biomarkers of brain contributions to CVD risk.","PeriodicalId":20913,"journal":{"name":"Psychophysiology","volume":" ","pages":"e14641"},"PeriodicalIF":2.9,"publicationDate":"2024-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141477325","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}
