Combining remote and collaborative research: A critical reflection on large-scale, comparative, and interdisciplinary research in times of a global crisis
No full textThis paper examines the methodological and ethical challenges of conducting remote research on child-animal relationships across thirty communities in 17 countries during the COVID-19 pandemic. It critically assesses remote research as a mode of collaboration informed by decolonial aspirations, highlighting the complexities of navigating temporal and geographical distances, mitigating global inequalities, and addressing political and methodological tensions at the intersection of psychological anthropology and cross-cultural developmental psychology. By engaging with these challenges, the paper fosters critical dialogue on research ethics and methodologies between anthropology and psychology, advancing a broader intellectual engagement toward translocal equity.

Distinct structural deficits in treatment-resistant schizophrenia and their putative neurotransmitter basis: a source-based morphometry analysis
No full textSchizophrenia is associated with widespread gray matter reduction. This is influenced by the underlying connectivity, resulting in covarying patterns of structural changes that are more pronounced in treatment-resistant individuals. However, it remains uncertain whether a distinct network of brain regions, with specific neurotransmitter basis, forms the substrate for treatment resistance in schizophrenia. We investigated the structural covariance networks (SCN) in 198 individuals; 55 with treatment-resistant schizophrenia (TRS) and 79 without TRS (non-TRS) in active symptomatic phase, and 64 healthy controls (HC) using Calhoun's Source-Based Morphometry. We mapped the putative neurotransmitter basis of the SCNs using a PET-based chemoarchitectural atlas. Twelve independent components (i.e., SCNs) were identified. A prefrontal-limbic SCN had lower gray matter volume (GMV) in TRS compared to HC and non-TRS (F = 7.757, p < 0.001, FDR-corrected). Spatial correlation with chemoarchitectural atlas revealed predominant contributions from serotonergic [5HT(1b) and 5HT(2a)], glutamatergic [mGluR(5)], histaminergic [H-3], and opioid [MOR] receptors for this TRS-related SCN (all p(spin-permutation) < 0.05, FDR-corrected). A different SCN comprised of dorsal fronto-temporal and parieto-occipital regions, not associated with any specific neurotransmitter distribution, exhibited reduced GMV in both TRS and non-TRS groups vs. HC (F = 7.239, p < 0.001, FDR-corrected). Amidst the generic GMV reduction that is shared with non-TRS patients, patients with TRS have specific prefrontal-limbic structural deficits with a unique non-dopaminergic chemoarchitecture. These findings indicate a putative molecular and structural basis for poor treatment response, guiding the development of second- and third-line pharmacotherapies for TRS
Comparing effects of episodic future thinking and cue salience to improve different types of prospective memory in typically developing school-age children
No full textProspective memory (PM) enables children to remember future intentions and is central to their development. Yet, school-age children face difficulties with remembering planned or assigned tasks and it is therefore crucial to uncover the methods for improving their PM performance. The present study examined the effects of two prominent methods - encoding PM tasks through episodic future thinking (EFT) versus increasing the salience of PM cues - in improving event- and time-based PM of school-age children. In two experiments, 8-12 year-old children (N = 126 and 126 respectively) completed three PM tasks and tasks tapping working memory, inhibition and shifting ability. Children were randomly assigned to the standard PM instruction group, the EFT group, or the cue salience group. In Experiment 1 (event-based PM), the cue salience group outperformed the other two groups in two computer-based PM tasks but not in a more naturalistic PM task. In Experiment 2 (time-based PM), the cue salience group outperformed the other two groups in all PM tasks, and this did not impair ongoing task performance and the cue salience group monitored the time less frequently. Moreover, children with lower shifting abilities showing larger benefits of salient cues on time-based PM. In both experiments, the EFT and standard groups had similar PM performance. These findings suggest that salient PM cues can improve event- and time-based PM in school-age children whereas EFT may not improve PM performance compared to standard encoding. Future research should investigate children's ability to voluntarily set salient cues for completing daily PM tasks.</p
Asian Evasion: Identifying and Countering a Bias Toward Avoiding Asians With COVID-19
No full textConverging evidence points toward the COVID-19 pandemic having amplified lingering anti-Asian prejudice and discrimination, including the virus's geographical origin being highlighted on social media. This amplification is consistent with theoretical frameworks and empirical findings that connect moral disapproval to biological aversion. Furthermore, experimental literature suggests that prejudicial stereotypes (e.g., of Black criminality) can prompt behavioral discrimination (e.g., disproportionate aggression in shoot/don't-shoot simulation tasks). Hence, we tested across four experiments (N = 2,844) whether prejudicial stereotypes of Asian infectivity, prominent during the COVID-19 era, might analogously trigger disproportionate avoidance. White participants (Experiments 1 and 2, United Kingdom and United States, crowdsourced) cross-culturally exhibited a pattern of Asian evasion on a custom-made approach-avoidance simulation task: they more readily avoided infected targets when Asian and more readily approached uninfected targets when White. However, Asian evasion waned after exposure to both associative pairings unsupportive of the stereotype and explicit media critique of the stereotype (Experiments 3 and 4: United States, crowdsourced). Our findings highlight how, even if the threat of COVID-19 induced anti-Asian aversions consistent with historical hatreds (i.e., "yellow peril"), some of those aversions may be readily remediated
Clinical Diagnostic and Prognostic Value of Residual Language Learning Ability in Patients with Disorders of Consciousness
No full textRecent research suggests that the detection of preserved cognitive function can assist in the diagnosis and prognosis of patients with disorders of consciousness (DoC). This study investigates EEG signals as indicators of neural activity associated with the processing of transitional probabilities during a learning paradigm in patients with DoC. By examining the sensitivity to transitional probabilities across levels of consciousness, we aim to assess the potential value of this indicator in clinical diagnosis and prognosis. We collected EEG recordings from 51 DoC patients (10 female) and 26 healthy controls (9 female). EEG activity was recorded while participants listened to artificial vocabulary speech sequences before and after the learning phase. Intertrial phase coherence (ITPC) was used to examine differences in neural responses in different learning phases. Results showed that minimally conscious patients showed a significant increase in the word-tracking response after the learning phase, similar to healthy controls. Moreover, their learning-mediated word-rate ITPC difference correlated significantly with their Coma Recovery Scale-Revised score and 6 month outcome. However, these correlations were absent in unresponsive wakefulness syndrome patients. Crucially, differences in vocabulary ITPC before and after the learning phase effectively discriminated between healthy controls and patients, as well as between minimally conscious and unresponsive wakefulness syndrome patients. Combining EEG indicators with clinical performance accurately predicted patients' prognosis. In conclusion, the language learning paradigm has the potential to contribute to both diagnosis and prognosis in this challenging population, thereby significantly reducing prognostic uncertainty in medical decision-making and benefiting the rehabilitation of DoC patients.</p
Alexithymia and Empathy in Parent-Youth Dyads: An Actor-Partner Interdependence Model Analysis
No full textParent-child interaction plays a key role in the development and maintenance of individual social emotional ability. Although studies have found that parents' alexithymia affects their offspring's social-emotional abilities, it is unclear how parents' and children's alexithymia affect each other and their empathic abilities. This study examined the relationship between college students' and their parents' alexithymia and empathy, focusing on both actor effects (individual-level associations) and partner effects (dyadic-level associations). A total of 1058 parent-youth dyads from a single college participated in the study, completing self-report measures of alexithymia and empathy. Using an actor-partner interdependence model analysis, the results revealed significant actor effects of alexithymia on cognitive empathy across all parent-youth dyads, though no such effects were found for affective empathy. Additionally, significant partner effects were observed, with sons' alexithymia linked to their fathers' cognitive empathy and mothers' affective empathy. These findings emphasize the complex dynamics of social-affective abilities within parent-youth relationships among college students and provide important implications for future research, intervention, and prevention efforts.</p
Effects of sensory processing sensitivity on depressive emotions in children with different intelligence in grades 5-9
No full text抑郁情绪是一种常见的负面情感状态，表现为持续性的情绪低落、兴趣减退或愉悦感丧失，常伴随精力下降、注意力难以集中、自我价值感降低、睡眠或食欲紊乱等生理心理变化。它与抑郁症不同，通常持续时间较短（数天至数周）、程度较轻，且未达到临床诊断标准，但若长期未缓解可能发展为病理性抑郁。
感觉加工敏感度作为一种与个体对环境刺激深度加工相关的特质，被认为是高智力儿童的一种特质，与抑郁情绪高度相关。然而，尽管高智力儿童群体中高感觉加工敏感度的比例较高，但其心理健康水平并未显著低于普通儿童。这一矛盾现象表明，智力可能在感觉加工敏感度对抑郁情绪的影响路径中起到调节作用。 而与普通儿童相比，高智力儿童的显著优势在于其更强的认知能力。因此，认知能力及其相关因素（如注意偏向控制、情绪调节策略等）可能在感觉加工敏感度与抑郁情绪的关系中发挥中介或调节作用，从而解释感觉加工敏感度对抑郁情绪影响的群体差异。
本研究分为两个研究。研究 1 使用问卷法，招募了3454 名被试，探讨在感 觉加工敏感度对抑郁情绪的影响过程中，智力直接和通过情绪调节方式中介的间接调节作用。研究 2 使用行为实验，按感觉加工敏感度（高 vs 低）和智力（高vs 普通）进行分组，从研究 1 中筛选出 154 名被试参与研究 2，采用点探测范式，通过不同刺激呈现时间（250ms、500ms、750ms、1250ms）考察感觉加工敏感度和智力对注意偏向成分的影响，并进一步讨论在不同感觉加工敏感度和智力分组下，注意偏向成分与抑郁情绪的关系。
研究 1 发现，感觉加工敏感度显著正向影响抑郁情绪。智力通过调节情绪调节策略间接影响这一路径：高智力正向影响认知重评，负向影响表达抑制，并能通过认知重评和表达抑制对感觉加工敏感度到抑郁情绪的影响路径进行间接调 节。
研究 2 结果表明：高感觉加工敏感度儿童对抑郁情绪刺激表现出更高的敏感性，倾向于采用注意回避策略来降低情绪负荷，同时在正性情绪刺激上存在注意解除困难，其注意加工机制与低感觉加工敏感度儿童存在显著差异；高智力儿童表现出对负性刺激的回避倾向和对正性刺激的持续关注，而普通儿童的注意偏向则表现出对刺激呈现时间的依赖性，其注意加工机制与高智力儿童存在显著差异；智力和感觉加工敏感度对注意定向加速和注意解除困难的交互作用未达到统计学显著性水平；感觉加工敏感度和智力分组的注意偏向成分对抑郁情绪的影响路径存在显著差异。该研究揭示了感觉加工敏感度和智力在抑郁情绪及注意偏向中 的复杂作用。
综上所述，高感觉加工敏感度个体对环境刺激高度敏感，其情绪调节模式既可能通过注意回避和认知重评实现情绪缓冲，也可能因依赖表达抑制而加重抑郁情绪。智力在情绪调节中具有一定保护作用，但其效果受感觉加工敏感度水平限制，对于高感觉加工敏感度个体仍需关注其情绪脆弱性。研究结果为高敏感人群的心理健康干预提供了重要依据。未来研究可进一步探索不同文化背景和年龄段个体的表现，以验证本研究结果的普适性。</p
Comprehensive assessment of phototherapy for depression disorder and interventional effects of mid-infrared phototherapy on depressive symptoms : a combined study of meta-analysis and randomized controlled trials
No full text抑郁症（Major Depression Disorder，MDD）是全球范围内最常见的精神障碍之一，严重影响患者的情绪、认知功能和自主神经系统调节，同时也给公共卫生带来沉重负担。传统治疗手段如药物治疗和心理干预虽能缓解部分患者的症状，但仍有较高的治疗耐受性问题及疗效有限的情况。因此，探索安全、有效的非药物干预手段成为当代精神健康研究的重要方向。光疗（Phototherapy）作为一种非侵入性治疗方式，近年来在精神疾病的治疗中备受关注，尤其是在调节生物节律、神经递质和神经炎症方面展现出潜在的临床价值。本研究的目的是通过荟萃分析评估光疗在抑郁症中的疗效，为光疗技术治疗抑郁症的优化和临床推广提供科学依据。同时探讨中红外光疗（Mid-infrared Light Therapy, MIRT）在改善亚临床抑郁青少年的情绪、执行控制及自主神经系统活动中的作用，并进一步本研究主要内容为探究光照疗法的抑郁干预，共由两部分组成。
研究一采用荟萃分析方法，通过 Web of Science、PubMed、EMBASE、Medline、 PsycInfo、ClinicalTrials.gov 等数据库进行系统检索，筛选随机对照试验（RCT）研究光疗在抑郁症的治疗效果，并通过 Revman 进行文献质量评估及数据合并分析。研究主要考察光疗治疗的亚组例如不同波长，不同亮度，不同治疗时长，不同被试年龄段以及是否有药物治疗对抑郁症的不同疗效。结果显示总体标准化均数差为-0.24（95% CI: -0.40~-0.08），具有统计学意义但效应量较小。亚组分析表明，全谱白光（SMD=-0.29）和高强度光疗（>5000 lux，SMD=-0.28）效果显著，长疗程（>1260 分钟）及中老年/青少年群体获益更明显，而联合药物治疗未显著增效。偏倚风险评估提示部分研究存在方法学缺陷，发表偏倚检测（Egger’s 检验 p=0.0148）显示阳性结果可能存在过度报道。本研究的局限性包括参数标准化不足和样本异质性，未来需规范干预方案并加强长期随访以提升证据质量。
研究二采用随机对照试验（RCT）方法，招募 18-22 岁的青少年被试，依据 症状自评量表（SCL-90）和患者健康问卷（PHQ-9）筛选出抑郁症状阳性组（n=54）及健康对照组（n=20）。抑郁症状阳性组随机分配至中红外光干预组（SPI, n=32）和非干预组（SPN, n=22），其中 SPI组接受14天，每天 30 分钟的中红外光干预，使用 fNIRS 监测执行控制任务（Stroop 任务）中的大脑神经活动变化”，数据采用双向重复测量方差分析（ANOVA）及配对样本 t 检验进行统计分析。 SCL-90 和 PHQ-9 量表结果显示，SPI 组在干预后得分显著降低（p < 0.01），表明抑郁症状明显缓解。在执行控制任务（Stroop 任务）中，SPI 组干预后前额叶功能连接性显著降低（p < 0.001），表明受试者在任务执行过程中消耗的认知资源减少，执行效率提高。此外，HRV 结果显示，SPI 组在干预后 LF/HF比值降 低（p < 0.05），RMSSD 和 HF 指标增加（p < 0.01），表明交感-副交感神经系统调节能力增强，自主神经系统功能恢复至更平衡的状态。这些结果支持中红外 光疗作为一种有效的非药物干预手段，对情绪调节、执行功能及自主神经系统调节具有积极影响。
本研究首次通过 Meta 分析结合 RCT 研究，通过荟萃分析初步评估光疗在抑郁症中的疗效，进而采用 RCT 实证探讨中红外光疗对抑郁症状及执行控制、自主神经功能的干预效果”。Meta 分析为规范干预方案提供理论依据，而 RCT 研究发现，中红外光干预可有效降低抑郁症状，提高执行控制能力，并改善自主神经系统功能，支持其作为一种安全、有效的非药物治疗手段在精神疾病干预中的应用。</p
Alpha transcranial alternating current stimulation modulates pain anticipation and perception in a context-dependent manner
No full textPain perception is closely tied to the brain's anticipatory processes, particularly involving the suppression of sensorimotor alpha-oscillations, which reflect the system's readiness for incoming pain. Higher sensorimotor alpha-oscillation levels are correlated with lower pain sensitivity. Alpha transcranial alternating current stimulation (alpha-tACS) can enhance these oscillations, potentially reducing pain perception, with effects that may be sustained and influenced by the certainty of pain expectations. Hence, this study investigated the immediate and sustained effects of alpha-tACS on pain anticipation and perception, focusing on how these effects are shaped by the certainty of expectations. In a double-blind, sham-controlled design, 80 healthy participants underwent a 20-minute session of real or sham alpha-tACS over the right sensorimotor region. Behavioral and neural responses related to pain anticipation and perception were recorded before, immediately after, and 30 minutes poststimulation under both certain and uncertain conditions. Compared with sham stimulation, real alpha-tACS disrupted the habituation of laser-evoked potentials (N2-P2 complex), particularly under certain expectations, with effects persisting 30 minutes poststimulation. In anticipatory brain oscillations, real alpha-tACS enhanced somatosensory alpha 1-oscillations and increased midfrontal theta-oscillations in conditions of certainty, with theta-oscillation modulation showing sustained effects. Mediation analysis revealed that alpha-tACS reduced pain reactivity by enhancing somatosensory alpha 1-oscillations but increased pain reactivity through the enhancement of midfrontal theta-oscillations, with the latter effect being more pronounced. These findings suggest that while alpha-tACS may provide pain relief through somatosensory alpha-oscillation augmentation, its stronger and longer-lasting impact on midfrontal theta-oscillations could lead to hyperalgesia, particularly in the context of certain pain expectations.</p
