We examined whether the neural state differs between spontaneous and volitionally controlled breathing and across the phases of breathing, inspiration and expiration. Magnetoencephalography (MEG) with a respiratory belt was used to record cortical oscillatory activity during spontaneous, deep, and square breathing (n = 33). Additionally, self-report measures of mood and arousal were applied to assess changes in the psychological state during the breathing techniques. Alpha power was suppressed during inspiration and increased during expiration (p &lt; .01) indicating dynamically fluctuating neural states across the respiratory cycle. This effect was observed in the sensorimotor areas during both spontaneous and volitionally controlled deep breathing. Compared to spontaneous and volitionally controlled square breathing, alpha power increased during deep breathing (p &lt; .01) within a cortical network extending to frontal and temporal areas. We also observed a steeper aperiodic slope and a broadband shift in the power spectrum in the left superior frontal gyrus during square breathing in comparison with spontaneous breathing suggesting that not only oscillatory activity but also the more general spectral characteristics of ongoing neural activity are modulated by the rate, depth, and pattern of breathing. Self-reported mood and arousal did not differ across the breathing techniques. Altogether, we demonstrate that neural activity is modulated by the phases of breathing and can also be volitionally influenced by varying the rate, depth, and pattern of breathing.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"197 ","pages":"Article 109026"},"PeriodicalIF":2.7,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143843941","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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 %).

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.

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}
