This research examined the link between persistence and cheating in 3- to 6-year-old children (2021-2022, N = 200, 100 boys; M_age = 4.85 years; all middle-class Han Chinese). Study 1 used a challenging game to measure whether children would cheat when they were allowed to play the game unsupervised. Results indicated that children's situational, but not trait, persistence negatively correlated with cheating: the higher children's situational persistence, the less likely they cheated. Study 2 not only replicated the results of Study 1 but also discovered that children who cheated became less persistent afterward. Our research reveals a novel bidirectional relation between situational persistence and cheating and underscores the importance of nurturing persistence in early childhood as a strategy to foster honesty.

Little is known about language development after late-to-moderate premature birth, the most significant part of prematurity worldwide. We examined minimal-pair word-learning skills in 18 eighteen-month-old healthy full-term (mean gestational age [GA] at birth = 39.6 weeks; 7 males; 100% Caucasian) and 18 healthy late-to-moderate preterm infants (mean GA at birth 33.7 weeks; 11 males; 100% Caucasian). Data were collected in the local urban area of Barcelona city from May 2015 to August 2016. Toddlers first associated two pseudo-words, forming a minimal pair based on a voice onset time distinction of the initial consonant, with two unfamiliar objects during a habituation phase. A visual choice test assessed their recognition of the two novel word-object associations and some familiar word-object pairs. While full-terms successfully mapped the similar sounding pair of novel words (d = 1.57), preterms could not (d = 0.17). These results suggest that late to moderate preterm birth can hinder basic associative learning mechanisms relying on fine temporal speech features.

Humans are driven by an intrinsic motivation to learn, but the developmental origins of curiosity-driven exploration remain unclear. We investigated the computational principles guiding 4-year-old children's exploration during a touchscreen game (N = 102, F = 49, M = 53, primarily white and middle-class, data collected in the Netherlands from 2021-2023). Children guessed the location of characters that were hiding following predictable (yet noisy) patterns. Children could freely switch characters, which allowed us to quantify when they decided to explore something different and what they chose to explore. Bayesian modeling of their responses revealed that children selected activities that were more novel and offered greater learning progress (LP). Moreover, children's interest in making LP correlated with better learning performance. These findings highlight the importance of novelty and LP in guiding children's exploration.

This study examined the influence of linguistic input on the development of productive and receptive skills across three fundamental language domains: lexico-semantics, syntax, and phonology. Seventy-one (35 female) Basque-Spanish bilingual children were assessed at three time points (Fall 2018, Summer 2019, Winter 2021), between 4 and 6 years of age, by specifically examining language knowledge and spontaneous language use in each language. A direct impact of the amount of linguistic exposure on the longitudinal growth of lexico-semantic and syntactic abilities was observed in both languages. While phonological skills were not directly influenced by exposure, they were more proficient in the more exposed language. The use of lexically diverse and syntactically rich utterances developed relatively later than language knowledge, both supported by the amount of linguistic exposure.

Religious decline, often observed among North American Christian youth, may not apply universally. We examined this and whether religiosity is associated with well-being, risk behavior, cultural values, and acculturation among 4080 Muslim and Christian adolescents aged 15-22 in Germany. Utilizing seven waves from the CILS4EU project and a person-oriented analytical approach, we identified different religious trajectories for Muslim (58% high, 31% low, 11% increasing), immigrant-origin Christian (68% low, 32% medium), and non-immigrant Christian (74% low, 17% decreasing, 9% medium) youth. High and medium trajectories were associated with greater well-being, lower risk behavior, more conservative attitudes, and less sociocultural integration. To fully understand religious development, we must consider diverse national contexts and groups, employing long-term perspectives and person-centered analyses.

Object exploration is considered a driver of motor, cognitive, and social development. However, little is known about how early childhood education and care settings facilitate object exploration. This study examined if children's exploration of objects during free play was facilitated by the use of particular spatial components (floor, tables, and activity centers) and types of play (solitary, social, and parallel). Participants were 61 children (aged 11 to 48 months and 50.8% boys, socioeconomic levels representative of the Dutch population). Intraindividual variability in children's object exploration was predicted by the use of particular spatial components and the social setting, with small-to-medium effect sizes. Solitary and parallel play were positively associated with complex object exploration, especially when sitting or standing at child-height tables. During social play, object exploration was mostly absent.

Parents' judgment of their children's cognitive ability is important for providing adequate learning environments. This study examined parents' judgment accuracy with 2346 children (M = 8.94 years; 48.3% girls) and their parents (1283 mothers, 426 fathers, and 637 parental pairs). The data were collected between September 2012 and February 2014 in Germany. Latent regression analyses were conducted for the overall sample and by grade (n_Grade1&2 = 830; n_Grade3&4 = 1516). Characteristics of the child (gender, birth order) and parents (gender, socioeconomic background) were investigated as moderators. Children's cognitive ability explained 34%/25%/37% (overall sample/Grade1&2/Grade3&4) of the variance in parental judgments. Judgments depended more on children's academic achievement than on cognitive ability. Parents judged their son's intelligence more accurately than their daughter's and first-born children more accurately than last-born children. Higher-educated parents showed higher judgment accuracy.

Autism spectrum condition (ASC) is characterized by atypical attention to eyes and faces, but the onset and impact of these atypicalities remain unclear. This prospective longitudinal study examined face perception in infants who develop ASC (N = 22, female = 5, 100% White) compared with typically developing infants (N = 131, female = 65, 55.6% White), tracking social-cognitive and ASC development through age seven. Reduced interest in direct gaze and eyes during infancy correlated with atypical development of adaptive behavior at age four and theory of mind at age seven. Principal component analyses revealed less integrated processing of facial features and eye-gaze information in ASC infants, potentially impacting their childhood social functioning. These findings highlight the intertwined nature of social-cognitive development and ASC.

How does one assess developmental change when the measures themselves change with development? Most developmental studies of word learning use either looking (infants) or pointing (preschoolers and older). With little empirical evidence of the relationship between the two measures, developmental change is difficult to assess. This paper analyzes 914 pointing, looking children (451 female, varied ethnicities, 2.5-6.5 years, dates: 2009-2019) in 36 word- or sound-learning experiments with two-alternative test trials. Looking proportions and pointing accuracy correlated strongly (r = .7). Counter to the "looks first" hypothesis, looks were not sensitive to incipient knowledge that pointing missed: when pointing is at chance, looking proportions are also. Results suggest one possible path forward for assessing continuous developmental change. Methodological best practices are discussed.
