To minimize some biasing factors, we proposed an experimental approach based on: (1) a homogeneous recruited sample, (2) an identical sequence of content-grouped affective pictures for emotion induction, (3) multi-distance forehead fNIRS recordings to separate cerebral from extra-cerebral components, and (4) a model-free frequency-based analysis to capture shared response patterns across individuals. We piloted a study to assess the feasibility of the approach in a sample of 20 young healthy women during an emotional task with affective pictures of neutral, sexual and violence content. We found coherent fNIRS responses to sexual and violence content located in slow fluctuations (0 - 0.019Hz), characterized by positive and negative oxygenation patterns of extra-cerebral and cerebral origin, respectively. Additionally, we corroborated the strong interference of surface hemodynamics.

To address this, we asked participants in the current study to categorise each trial as one of three strategies, and we examined the interaction between strategy type, accuracy and time-to-solution to predict pupil dilation. English-speaking students (n = 38) were asked to solve 120 compound word association problems, while pupil dilation was recorded. Subsequently, participants were asked to report which of the three problem-solving strategies (analytic, insight, combined) they had used to find each solution, without being if their answers were correct. A Bayesian linear mixed model analysis revealed an interaction between time-to-solution and strategy. More specifically, pupil dilation indexed an insight strategy for early solutions, but indicated an analytic strategy for late solutions, with combined strategies falling in between. In addition, correct trials were associated with greater pupil dilation. We conclude that, even within the same task, pupil dilation may separately indicate (1) the extended mental effort of problem analysis, (2) the immediate onset of insight, and (3) the feeling of uncertainty experienced when a correct answer is unvalidated by feedback.

One solution to differentiating trait-like risk factors from indicators of disease states is trait-state-occasion (TSO) modeling, a novel structural equation model that uses repeated observations to parse variance due to stable factors (i.e., trait) from that due to momentary changes (i.e., state). To date, TSO models have largely been applied to self-report data, with only a handful of studies applying TSO models to psychophysiological markers. Importantly, these psychophysiological studies have only applied TSO models to resting-state activity, making this the first study to model psychophysiological responses to stimuli in this way. This study conducted a “proof-of-concept” to examine trait- and state-variance in event-related potential (ERP) responses (specifically, startle-elicited N1 and P3 ERPs) to unpredictable threat in 83 adults across three time-points. TSO models were applied for the following condition contrasts: unpredictable shock&gt;no shock and unpredictable shock&gt;predictable shock. TSO models fit well for the N1 and P3 for both condition contrasts. In comparison to responses to no shock and predictable shock, respectively, the N1 and P3 to unpredictable threat showed substantial trait variance (N1 = 66 % &amp; 84 %, P3 = 69 % &amp; 71 %), less state residual variance (N1 = 32 % &amp; 15 %, P3 = 28 % &amp; 25 %) variance, and little autoregressive variance (N1 = 3 % &amp; 2 %, P3 = 4 % &amp; 6 %).

This study aims to provide background knowledge about the brain oscillatory dynamics and spatial field distributions of CT stimulation, by comparing the brain’s spectral power and the microstates to affective (stroking) vs discriminative touch (vibration) conditions. Thirty-four healthy participants (18 female) received tactile stimulation with a cosmetic brush at CT-optimal speeds or vibrotactile stimulation (at around 200 Hz) on the left forearm’s dorsum. They evaluated the pleasantness and intensity ratings of the stimulation while an electroencephalogram was recorded. Stroking stimulation was rated as more pleasant than the vibrotactile stimuli, with no significant differences in the intensity ratings. Power spectral density results revealed reduced power in alpha/mu and beta bands in central/Rolandic areas for the stroking condition compared to the vibration condition. Microstates analysis showed a reduced prevalence of class A and an increased prevalence of classes B and D during stroking. These findings indicate that CT-tuned stroking increased sensorimotor cortical excitability and engaged greater attentional resources, suggesting that this form of touch may be a prioritised type of information.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109018"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143744445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Feature-based attention is often assumed to operate in a spatially global fashion across the entire visual field, but there is also evidence that it can be restricted to task-relevant locations under some conditions. Here, we investigated whether such spatial filtering processes are already evident when representations of target-defining features (attentional templates) are activated during the preparation for an upcoming search episode. We measured N2pc components (an electrophysiological index of attentional allocation) in response to a rapid series of lateral task-irrelevant but template-matching colour probes that appeared while participants prepared for an upcoming search task with colour-defined targets. Critically, search targets would either always appear in the same lateral regions of visual space as the probes, or at different locations (near fixation or in lateral areas that never contained probes), thus rendering the probed locations either task-relevant or irrelevant. N2pc components triggered by target-colour probes during the preparation period emerged later and were attenuated when probes were presented at irrelevant locations. This demonstrates that the effects of preparatory feature-based attentional templates can be modulated by spatial expectations. However, this type of spatial filtering during search preparation only attenuates but not completely eliminates feature-based attentional modulations.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"196 ","pages":"Article 109016"},"PeriodicalIF":2.7,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conversely, later in adolescence there were decreases in delta power among cyberbullies, potentially reflecting an adaptive stress response. Longitudinally, cyberbully-victims retained more alpha power over time (i.e., into later adolescence) in frontal and central regions, suggesting greater cognitive effort in processing emotional experiences. Additionally, cyberbullies showed a relatively steeper decline in alpha power (into later adolescence) in frontal regions, possibly linked to impulsivity and higher levels of general aggression.

In a double-blind placebo-controlled design, 124 male students (mean age 25.18 ± 3) were administered intranasal oxytocin or a placebo and completed self-report questionnaires, an emotional flanker task, and an emotional rating task.

These findings suggest that oxytocin plays a role in shaping the association between emotion and cognitive control, specifically affecting the ability of cognitive control to regulate emotional responses, but not impacting emotional processing itself. The effect of oxytocin is attributed to its role in increasing approach motivation while reducing avoidance motivation—mechanisms supported by frontal-limbic interactions. Furthermore, it has been suggested that approach behavior is achieved by reducing inhibition. Therefore, the results may suggest changes in connectivity between frontal and emotional areas following oxytocin inhalation, leading to impaired regulation by cognitive control.
