While trait curiosity shapes children's early learning experiences, state curiosity is context-dependent fostering early learning, in-part, through information seeking behaviors. Here, we explore whether state-induced curiosity can influence exploratory behaviors and facilitate word-learning within a multimodal search task that mirrors real-world learning environments. Children (2.5- to 4-year-olds) will be introduced to novel objects and labels via a storybook. After exposure to each novel object, participants will locate the target object (i.e., a sticker depicting the novel object), hidden within one of ten boxes uniformly distributed across a real-world space. Unbeknownst to participants, the target will only be hidden within a single hemispace. In the \"High-Curiosity\" condition, the storybook should elicit greater curiosity, whereas the \"Low-Curiosity\" condition will present novel words in a context that should invoke lower levels of curiosity. Following the search task, participants will complete a forced-choice word learning task. Findings will provide insights into whether and how curiosity facilitates word learning in rich, multimodal contexts and how this relationship can be impacted by children's explorative strategies, including their sensitivity to environmental statistics. SUMMARY: Curiosity drives early development, but the extent to which it facilitates learning within a multimodal environment remains underexplored. The study examines how high versus low induced curiosity states influence toddlers' exploratory behavior, including search efficiency and adaptation to spatial probability cues. The study assesses whether higher state-induced curiosity leads to stronger retention and recognition of novel word-object mappings compared to the lower curiosity condition.

To date, however, it is unclear how learners of different ages predict upcoming experience when navigating environments with complex structure, as well as how changes in predictive learning mechanisms influence structured knowledge acquisition. To address this question, we tested 106 children, adolescents, and adults, ages 8-22 years, on a predictive learning task, in which they experienced sequences of stimuli with a higher-order temporal structure. After an initial learning phase, participants' explicit knowledge of the relations between stimuli was probed via two additional task measures. We used a recently introduced computational model to characterize participants' response times during learning, and found that all participants relied on simple, recency-based prediction, anticipating that they would encounter stimuli they recently encountered in the past. With increasing age, however, participants demonstrated greater evidence of additionally relying on a more sophisticated learning mechanism, which captured a predictive representation of the conditional relations between stimuli. Though predictive learning changed with age, we found only weak evidence that these changes related to the acquisition of explicit knowledge of the environment. Our results suggest that the learning mechanisms through which people parse continuous streams of experience change with age, influencing their predictions about upcoming events. SUMMARY: Children, adolescents, and adults all learn to segment continuous streams of structured perceptual input, but they may do so via different learning processes. We examined how the learning mechanisms that enable people to predict upcoming experiences change and relate to structured knowledge acquisition across development. Computational modeling revealed that in a graph-learning task, younger participants relied on simple, recency-based prediction, while older participants tracked temporal relations between stimuli.

Yet, research on infancy suggests that the first year of life can be characterised by a different developmental pattern: increased negative affect as infants age. Implementing an emotion-eliciting task, we measured infants' observed emotion reactivity and regulation, and physiological arousal (heart rate) during the challenge (toy retraction) and recovery (toy play) conditions at age 6 months (n = 82, 43 boys) and age 12 months (n = 68, 36 boys) continuously on a second-by-second basis. We first measured mean intensity of reactivity, regulation, and arousal by calculating within-person averages. Then, we measured three temporal dynamics: estimates of variability by calculating variance, lability by calculating root mean square of successive differences, and persistence of changes by calculating autocorrelation. Intensity, variability, and lability in negative reactivity increased from 6 to 12 months with no change in persistence, indicating a larger and quicker negative reaction to toy retraction with age. Regulatory strategy use increased from 6 to 12 months during challenge, whereas during recovery, it reduced and became more stable. Heart rate decreased from challenge to recovery at 12 months but not at 6 months. We then examined how the temporal associations between reactivity, regulation and arousal change over time. Cross-correlation analyses revealed stronger temporal associations between reactivity, regulation, and heart rate at 12 months, suggesting increased coherence between behavioural and physiological responses with age. We discuss these developmental changes in emotion dynamics and behaviour-physiology associations in the context of functionalist perspectives on emotion. SUMMARY: This study employs momentary recordings of emotional expressions, regulatory behaviours, and physiological arousal, focusing on two key aspects: within-task context and temporal dynamics. As they grow, infants show stronger negative reactions and greater regulatory efforts during stress but calmer reactions and reduced use of regulation once stressor ends. Temporal associations between emotional behaviours and physiology (heart rate) increased from 6 to 12 months, suggesting stronger emotional coherence with age in infancy. Together, these patterns may reflect improved emotional flexibility, with older infants showing more context-appropriate emotion responses.</p>","PeriodicalId":48392,"journal":{"name":"Developmental Science","volume":"29 4","pages":"e70212"},"PeriodicalIF":3.2,"publicationDate":"2026-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13144710/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147844717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach allows for the simultaneous estimation of each partner's effect on their own subsequent looking and on their partner's subsequent looking. Analysis of gaze data from head-mounted eye trackers worn by North American, middle-class, racially and ethnically diverse caregivers and infants (21 infants and 25 parents were White and not Hispanic; the remaining identified as Asian, Black, Multiracial, or another race, and/or as Hispanic) revealed that infants' and caregivers' looks at a moment was related both to their own subsequent looks and to their partners' subsequent looks. Moreover, infants' looks to their parents' faces more strongly predicted parents' subsequent looks to their infants' faces than the reverse, suggesting that mutual gaze was primarily driven by infants' attention. In contrast, there was no difference in infants' or parents' influence on their partners' looking at objects, indicating that joint attention emerged through mutual coordination. Furthermore, there was a stronger effect of gaze on subsequent gaze for infants than for parents, suggesting that infants' attention was more sustained and less flexible than that of their caregivers.

However, past research on material hardship is limited by cross-sectional data and reliance on conventional behavioral measures of cognitive functioning that suffer from poor reliability and lack of specificity. To address these gaps, this study used a well-validated computational model of cognition to examine individuals' drift rate, which is hypothesized to be driven by the efficiency of evidence accumulation (EEA) for decision-relevant information, a key process that supports higher-order cognitive functioning. Here, we examined how material hardship during childhood was associated with adolescent drift rate, and whether drift rate was linked with attention difficulties. 187 adolescents recruited from the Future of Families and Child Wellbeing Study were included in the analyses. Adolescents exposed to greater material hardship showed lower drift rate, suggesting less effective processing. Growth curve modeling revealed that initial exposure to material hardship, but not changes across childhood, was associated with drift rate in adolescence. Lower drift rate was also associated with concurrent attentional problems and served as a significant indirect pathway linking material hardship to adolescent attention. This is the first longitudinal study that examined the associations among childhood material hardship exposure, adolescent drift rate, and attentional difficulties. Our results suggest that challenges to essential living conditions in childhood may impact cognitive processes underlying goal-directed behavior in adolescents. These findings highlight the application of computational models to reveal specific cognitive processes impacted by adversity.

We approximate toddlers' central visual field experience by cropping image regions from a head-mounted camera centered on the current gaze location estimated via eye tracking. This visual stream feeds a neural network model, which uses a biologically plausible unsupervised learning objective. Our experiments demonstrate that a few minutes of such first-person experience suffice to learn strong object representations permitting invariant object recognition. Importantly, by simulating alternative gaze behaviors we show that toddlers' eye movement patterns play a crucial role in this. Our analysis also reveals that the limited size of the central visual field where visual acuity is high plays an important role for successful learning. Together, this highlights the benefits of temporally structured visual experience arising from toddlers' natural interactions with objects.
