The present experiment combined sensory preconditioning and deferred imitation to investigate the minimal conditions under which 6- and 9-month-olds form associations between co-occurring stimuli without exogenous reinforcement and retain this information for at least 48 h. Six-month-olds demonstrated robust learning transfer 2 days after a single 1-min, 52-s exposure to two stationary puppets in their visual surround. A single 56-s exposure or two 56-s exposures on consecutive days were ineffective. Nine-month-olds showed learning transfer after substantially longer exposure that involved stimulus movement (15 min). Additionally, age-related differences emerged in the conditions that supported learning; 6-month-olds rapidly formed and retained associations following simultaneous exposure, whereas 9-month-olds did so only after sequential exposure. These findings highlight ontogenetic differences in the constraints of associative learning and are discussed in relation to domain-general learning mechanisms.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12961572/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147354145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This preference may lead DP individuals to focus on horizontal facial information and ignore other information.Methods: Experiment 1 explored whether there was a difference in horizontal preference between the DP group (N = 27) and the control group (N = 47) and whether this preference was based on facial rotation or low-level horizontal (vertical) information. Experiments 2a and 2b used behavioral and eye-movement techniques to explore whether the DP (N = 73) and control groups (N = 58) had preferences for horizontal (vertical) configuration.Results: Experiment 1: The results showed that the control group and DP group preferred the horizontal feature information (this preference was not affected by rotation orientation) of faces. Experiments 2a and 2b: The results showed that the DP group had a preference for vertical configuration, while the control group had a preference for horizontal configuration.Conclusions: In summary, the control group and the DP group preferred low-level horizontal facial information, and these preferences were not affected by facial rotation orientation. However, regarding spacing configuration, the control group preferred a horizontal configuration, whereas the DP group preferred a vertical configuration. This finding is crucial for elucidating the face preferences in individuals with DP and deepening the comprehension of the associated cognitive-behavioral patterns.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70137"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147503397","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While rodent models have demonstrated lasting neurobehavioral changes following prenatal and/or perinatal exposure to APAP, few studies have examined such effects in zebrafish (Danio rerio), and none have done so in the translationally relevant context of systemic inflammation. Zebrafish eggs were treated with Escherichia coli-derived lipopolysaccharide (LPS) and/or APAP in the first 24 h postfertilization (hpf). At 96 hpf, larval behavior was recorded during a light/dark transition test. Results showed embryonic APAP exposure elevated swim velocity, with APAP-treated larvae displaying more activity than those not treated with APAP. We also found significant interaction between LPS and APAP exposures, with \"two-hit\" LPS + APAP larvae exhibiting increased activity relative to LPS- and APAP-only groups during the dark phase. APAP-treated larvae also exhibited greater activity than controls during the light phase. In addition, LPS + APAP larvae displayed significantly fewer clockwise relative to counterclockwise rotations compared to LPS-only larvae. To explore a potential mechanism underlying observed behavioral differences, we analyzed glycogen synthase kinase-3 (GSK-3) Y216+Y279 ɑ/β phosphorylation and total levels in homogenized whole-brain tissue. Unexpectedly, the ratio of pGSK-3/total GSK-3 was not affected by any treatments. Nevertheless, this study demonstrates the utility of zebrafish as a model for studying the combinatorial effects of exposures such as inflammation and APAP early in life.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70138"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147472628","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At a long-term (Myears = 5 years, SD = 0.9) follow-up assessment, respiratory sinus arrhythmia (RSA) was assessed for a subset of these mother-child dyads during three dyadic interaction tasks: a baseline video, an affiliative discussion task, and an active cooperation task. Children displayed a significant decrease in RSA from the baseline video to the affiliative discussion task, whereas mothers displayed a significant decrease in RSA from the discussion task to the active cooperation task. Although no main intervention effects were found, differing patterns of child RSA in intervention groups were observed when accounting for time since intervention. Compared to the control group, children in the TP2 group exhibited relatively stable patterns of RSA, whereas children in the PN group exhibited RSA levels that decreased as time since intervention increased. These divergent patterns may reflect fundamental differences in the developmental scope of the two interventions. Together, these findings suggest that brief parenting interventions may differentially influence the stability of children's autonomic regulation during interactions with their caregiver, depending on their developmental focus and timing of delivery.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70147"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147510177","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We employed DeepSqueak, a deep learning system, for automated unsupervised USV classification and detailed analysis of temporal and syntax changes, comparing it to manual coding for call number, duration, and frequency. Offspring of Long Evans rat dams, fed a high-fat or control diet for three weeks premating and throughout gestation and lactation, received 0.05 mg/kg intraperitoneal nLPS or saline on postnatal days (PND) 3 and 5 (n = 5-6 per condition, total N = 41). On PND 7, USVs were recorded after a brief maternal separation. DeepSqueak yielded 97% concordance (p > 0.8 vs. manual); mHFD increased bout duration by 25% (p < 0.01), and nLPS increased calls per sequence by 30% (p < 0.05). DeepSqueak matched manual accuracy, with automated analysis revealing that mHFD and nLPS significantly prolonged sequence durations and altered syntax transition probabilities. These findings suggest that temporal and syntactic USV features are sensitive markers of early inflammatory stress.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70142"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12995509/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147472570","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, most are not designed to accommodate curly and coiled hair types, prevalent among individuals of African descent. This limitation results in the collection of suboptimal data that may be excluded from scientific research, raising questions about the generalizability of findings and the applicability of resultant knowledge to these populations. In response, researchers have proposed more inclusive EEG methodology, including using caps with tall pedestals and braiding techniques to improve data quality. Despite this advancement, tall pedestal nets fall short in addressing the need for clear scalp exposure, which is particularly important when capping children with voluminous hair. Similarly, braiding techniques have shown promise in small-scale studies involving adults, but their broader application remains unexplored in younger populations. To bridge these gaps, we introduce a novel approach for advancing representation and validity through the integration of curly hair specialists (CHSs) in pediatric EEG research. We examine the multifaceted role of CHSs and outline the processes involved in conceptualizing, developing, and implementing the CHS Initiative. We also offer a modified design for implementing this model in less resourced contexts and discuss community-based participatory research methods that informed our approach.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70120"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13143345/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147503403","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Attachment strategies can shift across the lifespan as individuals encounter new interpersonal and emotional experiences. Additionally, neural changes during development may influence these strategies. A systematic review and an activation likelihood estimation meta-analysis were conducted to examine the associations between insecure attachment dimensions and brain activations during socio-affective stimuli tasks according to age. The review adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and was registered on PROSPERO. The research identified 1743 articles, of which 15 were included. The results showed that, in younger individuals, the avoidant attachment dimension was associated both negatively and positively with activations in limbic regions, located at the level of Brodmann Area (BA) 13 (insula) and the medial globus pallidus and amygdala, while in older individuals, it was associated only negatively with sub-lobar activations in the caudate tail. Moreover, in younger individuals, the anxious attachment dimension was associated both negatively and positively with activations in several heterogeneous neural areas. Differently, in older individuals, the anxious attachment dimension showed only positive associations with neural activations, particularly in limbic regions, located at the level of BA 35 (parahippocampus) and 38 (temporal pole). These preliminary findings suggest potential differences in the neural correlates of insecure attachment according to age. It could be supposed that younger individuals have more flexible and less structured attachment-related regulatory strategies than older individuals, suggesting relevant clinical implications for attachment-based psychological interventions.","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":"e70146"},"PeriodicalIF":1.9,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147510300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using sensory preconditioning, deferred imitation, and associative inference paradigms, we characterized the properties and constraints of these emerging networks. Experiments 1A-1B revealed that 6-month-olds linked overlapping stimulus pairs encountered on successive days (AB, BC), enabling learning transfer between stimuli that never co-occurred (A-C). Experiments 2A-2B extended these findings to more complex four- and five-stimulus conditions (e.g., AB, BC, CD, DE). Infants’ mnemonic networks exhibited bidirectional connections, response transfer regardless of element location (Experiments 1A-2B), and specificity, as they did not generalize to unrelated stimuli (Experiment 2B) or after exposure to unpaired stimuli (Experiment 1A). At the same time, we identified constraints in mnemonic networks; associations were pruned through extinction (Experiments 1A-1B) and persisted for 2 days but not 5 (Experiment 1C).
