Although prior research has shown that self-control is associated with achievement motivation, it remains unclear which neural substrates underlie the association between self-control and achievement motivation. To address this issue, we employed resting-state functional connectivity (RSFC) and mediation analysis methods to investigate the neural basis of the relationship between self-control and achievement motivation in the discovery (<em>N</em> = 685) and replication sample (<em>N</em> = 210). In discovery sample, we found a significant positive correlation between self-control and achievement motivation. On the neural level, the FC between the left dorsolateral prefrontal cortex (dlPFC) and the right superior temporal gyrus (STG), right inferior temporal gyrus (ITG), and left middle temporal gyrus (MTG) were negatively correlated with self-control. Furthermore, the mediation analysis demonstrated that self-control fully mediated the relationship between the FC between left dlPFC and the right ITG and achievement motivation. Repeating analyses in the independent replication sample also supported the robustness of the results obtained in the discovery study. Together these findings indicate that the FC between left dlPFC and right ITG may represent a key neural pathway through which self-control influences achievement motivation, providing new insights into their association from a neural perspective.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"200 ","pages":"Article 109114"},"PeriodicalIF":2.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144925204","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}

These studies typically employed traditional analysis methods that focus on a limited number of electrodes and timepoints, which increases the risk of statistical errors. Moreover, no studies have investigated these issues for emotionally ambiguous facial expressions. Therefore, the current study aimed to investigate whether working memory loads influence ERP effects of positive, negative and importantly, emotionally ambiguous (e.g., surprised) facial expressions by using robust Mass Univariate Analysis (MUA). To address these issues, thirty-three participants were presented with angry, happy, surprised or neutral faces. Participants were required to memorize a letter (low working memory loads) or 5 letters (high loads) before face presentations and to recognize them afterwards. ERP results showed that working memory loads and facial expressions independently affected ERP responses, with no significant interaction. Working memory loads influenced ERP responses starting after the P100 peak. Regarding the effect of facial expressions, surprised facial expressions generally weakened late positive potential (LPP) responses compared to other facial expressions, and happy facial expressions weakened the responses at early time ranges, while angry facial expressions enhanced LPP responses at distinct electrode sites depending on the comparison. These findings underscore the value of employing MUA for comprehensive ERP analysis in face processing research.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"200 ","pages":"Article 109116"},"PeriodicalIF":2.9,"publicationDate":"2025-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144996767","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}

In a 2 × 2 within-subjects experiment, 75 participants (<em>M age</em> = 19.89, 77.30 % women), were exposed to repeated trials of warm or neutral temperature packs, combined with deep or light pressure from weighted blankets, while they viewed images of close others.

After adjusting for age, there was an interaction such that warm deep pressure increased feelings of social connection compared to warm light pressure and neutral deep pressure. Individual differences in interoceptive sensibility also moderated effects, with greater clarity in interoceptive signals predicting higher feelings of social connection during warm deep pressure (vs. warm light pressure). The combination of warmth and pressure, therefore, increases feelings of social connection toward close others compared to warmth or pressure alone.

Despite considerable research interest, results have shown considerable variability across studies. Several meta-analyses have been conducted to help address this inconsistency. However, conducting a meta-analysis requires researchers to make numerous decisions, such as defining inclusion criteria and analytical techniques. In response to this challenge, a ‘multiverse’ approach can be used to simultaneously explore a range of different potential and realistic scenarios by systematically varying these analytical decisions. In this study, we performed a multiverse meta-analysis to investigate how researcher decisions can influence outcomes in meta-analyses of oxytocin administration studies. We systematically varied inclusion criteria, data synthesis models, and methods for correcting publication bias across 530 effect sizes derived from 185 studies, conducting 256 distinct meta-analyses. Our results demonstrate that summary effect estimates can vary considerably depending on meta-analytic decisions (from <em>d</em> = −0.16 to <em>d</em> = 1.45). Notably, meta-analyses with neurotypical populations tended to yield larger effect sizes than non-neurotypical populations, and multiple administrations studies tended to yield larger effect sizes than single administration studies. Furthermore, summary effect estimates can substantially vary according to the applied publication bias correction method. Our findings also demonstrated that the current evidence mostly supports the presence of the effect of oxytocin across domains, regardless of meta-analytic choices, as over 90% of the observed meta-analyses exceeded the range of bootstrapped meta-analyses assuming a null effect. These results warrant future research on how different contexts may impact the robustness of the effects of oxytocin, while underscoring the value of meta-analysis pre-registration to facilitate the transparent evaluation of meta-analyst decision-making.</div></div>","PeriodicalId":55372,"journal":{"name":"Biological Psychology","volume":"201 ","pages":"Article 109112"},"PeriodicalIF":2.9,"publicationDate":"2025-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144979668","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}

However, variations in cognitive tasks and stimulation protocols across studies led to mixed results, rendering findings and conclusions incomparable. In this study, we synchronized oscillations over two main areas of the frontoparietal cognitive network, right dorsolateral prefrontal cortex (rDLPFC) and right posterior parietal cortex (rPPC), using high-definition (HD) dual-channel in-phase transcranial alternating current stimulation (tACS) at various stimulation frequencies (6 Hz, 40 Hz, sham).

However, whether these limbic areas regulate cortisol stress reactivity and recovery differently remains elusive. Using the Seed-to-Voxel gPPI analysis, we explored the functional connectivity (FC) between the limbic area and other brain regions during stress induction and their association with cortisol stress reactivity. Similarly, we explored their FC during post-stress rest and their association with cortisol stress recovery. We found that both BLA and CMA connectivity related to cortisol stress reactivity during stress induction, with similarity in FC with precuneus and differences in FC with angular gyrus, precentral gyrus, and PFC; the BLA rather than CMA connectivity with PFC linked to cortisol stress recovery during post-stress rest. Furthermore, the hippocampal-PFC connectivity only affected cortisol stress recovery during post-stress rest, and in a different direction from the effect of BLA-PFC connectivity.

Three hours later, participants completed a harm-avoidance task, learning over time to choose the option with a lower probability of electric shock to avoid harm either for themselves (Self condition) or for a stranger (Other condition). Behavioral analyses revealed that testosterone administration prolonged recipient differences across trials compared to placebo. Computational modeling quantified these recipient differences which were likely caused by testosterone administration. A reinforcement learning model with dual learning rates for positive and negative prediction errors (PEs) best accounted for individuals’ choices. Analysis showed that, compared to placebo, testosterone enhanced learning from negative outcomes but suppressed learning from positive outcomes in the Self condition, without affecting learning rates in the Other condition. Additionally, testosterone administration slowed prosocial learning from negative outcomes compared to placebo and reversed its positive relationship with trait anxiety. Collectively, our findings offer precise computational insights into the role of testosterone administration in harm-avoidance learning.
