This study investigates mother-infant behavioural and thermal affective responses to parental digital and non-digital distractions. Thirty-eight mother-infant dyads (22 males) participated in a modified Still-Face Paradigm with five conditions: Free Play, Technoference Exposure (TF-E), Technoference Reunion (TF-R), Paperference Exposure (PF-E), Paperference Reunion (PF-R). During TF-E and PF-E mothers completed questionnaires on a smartphone or paper and were unresponsive to the infant. Mother-infant behaviours were coded microanalytically, while FLIR cameras detected changes in forehead and nasal tip temperatures. Maternal habitual smartphone use was assessed by self-report and passive sensing. Infants showed increased behavioural distress during TF-E and PF-E. ITI revealed lower infant forehead temperatures during TF-E compared to free play and reunions, while no significant changes at the nasal tip. Maternal forehead temperature dropped significantly during PF-E, compared to other episodes. Greater maternal habitual phone use was linked to infant responses and maternal behaviours. Parental unresponsiveness due to digital and non-digital distractions leads to infant behavioural distress, with digital disruptions also triggering a distinct thermal affective response.

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}

Participants (<em>N</em> = 167 with <em>n</em> = 904 datapoints; aged 12.0–17.9 years) completed EEG and other assessments at 4 monthly-intervals for five years. Results revealed several associations between EEG power across brain regions and various cyberbullying roles. Key findings include a decrease in EEG power across all frequency bands over time across the entire sample, aligning with typical developmental patterns. However, in early adolescence, cyberbully-victims exhibited lower delta power compared to other groups, which may suggest heightened emotional reactivity. 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. Longitudinal analyses highlight the importance of early interventions to target cognitive and emotional processes that may be implicated in cyberbullying in order to reduce the impact of cyberbullying and protect the mental health of adolescents.

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}

We recorded EEG from 40 participants while they completed a wheel-of-fortune task under conditions of risk and ambiguity in both contexts. We observed a stronger valence effect on the P3a in the loss context under risk, but a stronger valence effect on the P3b in the gain context under ambiguity. Further comparisons revealed that feedback evaluation was primarily driven by a smaller P3a in response to losses under risk, but by a larger P3a and P3b in response to gains under ambiguity. Parametric analyses found that both the reward positivity and P3a for gains and nongains were modulated by winning probability under risk, while the P3a for gains was influenced by ambiguity level under ambiguity.

Previous studies demonstrated that tasks that recruit cognitive control attenuate the emotional interference effect, enhancing emotion regulation.

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. Consistent with our hypotheses, we found that oxytocin significantly reduced the effect of cognitive control on emotion. However, counter to our prediction, it did not affect emotional experience or perception. 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.

The objective of this study was to track the neural activity associated with the violation of expectations about hostile vs. nonhostile intentions in aggressive and nonaggressive individuals when facing conflicting contextual and behavioral cues in a given social situation.

Taken together, the results suggest that aggressive individuals demonstrate an impulsivity in their decision-making about other people’s intentions.
