Grounded in lived experience and sociocultural literature, we aimed to develop and evaluate culturally responsive best practices for participant interaction and hair preparation to increase Black participant inclusion in fNIRS research. First, we developed an intake survey, guidelines for researcher staffing and training, and a suite of customizable hair preparation techniques that prioritize participant comfort and hair integrity. We then evaluated these techniques with 19 Black participants (11 adults, eight children) with varying hair types/styles; methods included braiding cornrows around the intended optode montage, using gels and clips to part hair, and various ways of increasing tension to promote sensor–scalp contact. On average, signal quality improved by 50%, with the greatest improvements in anterior regions. While signal quality was not perfect, it was generally improved to the point of acceptability and inclusion in a racially/ethnically diverse dataset (with hair type/color as covariates). We conclude with recommendations for increasing awareness of racial bias in neuroimaging, greater diversity in research teams, and a more inclusive approach for working with diverse populations.</p>","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 2","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-02-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/dev.70134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146124045","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}

Using a reward-feedback-based simulation, participants engaged in decision-making tasks involving ambiguous outcomes while their heart rate, decision time, hesitation behavior, and verbalized thought processes were systematically recorded. Findings demonstrated that uncertainty led to increased physiological arousal, longer decision times, greater hesitation, and lower decision accuracy. Regression analysis revealed hesitation as the strongest predictor of physiological arousal (BPM difference), whereas decision time and accuracy were not significant. Notably, participants’ dominant task value orientation—classified according to the situated expectancy-value theory (SEVT)—significantly influenced both physiological and cognitive outcomes. Children with utility-driven motivation exhibited the highest decision accuracy and lowest physiological stress, whereas those motivated by perceived cost showed the opposite pattern. These results provide empirical support for behavioral and physiological responses associated with uncertainty and highlight the importance of developmentally tailored interventions in educational settings.

However, there is limited research on the effects of neonatal CBD exposure. The present study investigates the efficacy of CBD treatment in mitigating neonatal vocalization responses, as well as short- and long-term behavioral outcomes following neonatal pain exposure. We show that neonatal pain exposure decreases USV emission and increases adult anxiety-like behavior in male rats compared to neonatal touch exposure. Neonatal CBD treatment also decreases pups’ USV lengths and male pups’ USV counts compared to vehicle treatment but is unable to rescue the neonatal pain-related increased anxiety-like behavior in adulthood.

To index early auditory discrimination, researchers measured brain function in relation to the detection of different sounds with an event-related potential (ERP) called the mismatch response (MMR). The current study aimed to examine associations among socioeconomic circumstances, the home language environment, home noise exposure, and the MMR in a socioeconomically, racially, and ethnically diverse longitudinal sample of 6- and 12-month-old infants. Socioeconomic circumstances were measured prenatally via parent report. The home language environment and home noise levels were measured using digital language processing devices when infants were approximately 6 months of age. The MMR was elicited during a passive auditory oddball task at two timepoints—6 and 12 months of age. Results showed that neither SES, the home language environment, nor home noise levels predicted infant MMR at either age.
