Here, we use time-frequency analyses of human electroencephalogram (EEG) data to explore the aftereffects of two such mechanisms: target amplification and distracter inhibition. Participants completed a set-shifting task in which interference during switch trials could either result from the persisting amplification of previous target colors or the persisting inhibition of previous distracter colors. In a first set of analyses, we focused on frontal midline theta (FMT) as a time-continuous marker of overall interference. Compared to a control condition, we found transient peaks of FMT in both experimental conditions that matched the effects of persisting target amplification and distracter inhibition predicted by a computational model of the task. In a second set of analyses we used steady-state visually evoked potentials (SSVEPs) as a direct measure of the attentional resources allocated to target and distracter colors. However, SSVEP amplitudes did not differ reliably between stimulation frequencies during switch trials, preventing us from drawing further conclusions on the origins of the interference processes reflected in FMT dynamics.

The aim of the present study is to further investigate the impaired processing of social reward anticipation and reward consumption in individuals with IGD, and explore the relationship between these two components. Using a social incentive delay task with game-related and real-life versions, combined with event-related potential (ERP) technology, we examined 25 individuals with IGD and 25 matched healthy game players. The results showed that, at the behavioral level, individuals with IGD showed significantly slower reaction times to real-life target stimuli compared with game-related target stimuli, which is not observed in healthy controls. At the neural level, the Cue-P3 elicited by real-life incentive cues in individuals with IGD was significantly smaller than that elicited by game-related incentive cues. However, these effects were no longer significant after adding depression and anxiety scores as covariates. There was no significant difference in reward positivity (RewP) elicited between the two types of reward consumption. Furthermore, individuals with IGD showed a positive correlation between Cue-P3 elicited by game-related social incentive cue and RewP elicited by game-related social reward. However, this effect was not observed in the healthy controls. In conclusion, the present study suggests that the blunted allocation of motivated neural attention resources to real-life social incentive cues in individuals with IGD may be the key mechanism underlying their impaired social reward processing. This impairment may be influenced by the higher levels of depression and anxiety symptoms commonly observed in individuals with IGD.</p>","PeriodicalId":54945,"journal":{"name":"International Journal of Psychophysiology","volume":" ","pages":"112479"},"PeriodicalIF":2.5,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142787911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a re-analysis of a previously published study that found depression to be associated with blunted systolic blood pressure (SBP) and heart rate responses (HR), we used cross-sectional network models to examine if anhedonia symptoms were key drivers of this observation. Healthy young adults (N = 180) completed measures of depression symptoms (Hospital Anxiety and Depression Scale (HADS)) and had their blood pressure and heart rate monitored throughout a standardized stress testing protocol. Using network analysis, a Walktrap algorithm identified two clusters of depressive symptoms: anhedonia and non-anhedonia. These anhedonia symptoms of depression, but not the non-anhedonia symptoms, were associated with blunted SBP and HR reactivity, such that those scoring higher on HADS-D items capturing anhedonia displayed more blunted cardiovascular response profiles.

A total of 324 community recruited participants (age range 15-93 years) completed standard self-report scales of CT, anxiety and depression, and also underwent an eyes-closed resting state EEG recording session. Based on several functional neuroimaging studies, which have shown that connectivity in the salience network with major nodes in the anterior cingulate cortex (ACC) and insula is modulated by CT, we derived salience network connectivity measures from resting state EEG source imaging. Also given that theta band (3-7 Hz) neural oscillations have been shown to have an ACC source, we specifically focused on theta band salience network connectivity. The results showed significant positive correlation between CT and both anxiety and depression. We also found that theta band salience network connectivity, but not network activity, had a significant inverse relationship with CT and specifically mediated the relationship between CT and anxiety, but not depression. Interrogating the subcomponents of CT, theta connectivity in the salience network mediated the relationship between anxiety and both emotional abuse and physical neglect.

To test associations of uncertainty and the ERN, a preregistered, randomized-controlled design was employed. After measuring the baseline ERN of N = 120 university students, a subsample was randomly assigned to two groups: While an intervention group (n = 30) performed an unsolvable probabilistic \"learning\" task intended to induce state uncertainty, a passive control group (n = 30) rested. Subsequently, the ERN was assessed again. Self-reported uncertainty was assessed before and after the intervention.

This analysis comprised psychophysiological data from a total of N = 355 participants. Cross-sectionally, no effects of IU on the ERN emerged. Regarding the state uncertainty induction, the intervention group displayed increased self-reported uncertainty after the intervention, but no evidence emerged for ERN alterations attributable to the intervention.

The absence of evidence for mechanistic changes in the ERN due to a successful induction of state uncertainty further questions a link between IU and the ERN.

Three patterns emerged regarding psychophysiological processes in older adults: altered mind-body connections with age were associated with reduced high-arousal and increased positive emotional experiences, cognitive protective effects, and improved body representation that correlated with better interoceptive sensitivity.
