Specifically, we were interested in whether empathy increases with fathering experience. In two preregistered online studies (<i>N</i> = 1,046, primarily from the United Kingdom and the United States), participants' task was to rate their affective responses to emotional pictures of children (affective empathy) and to recognize children's emotions from pictures of the eye area (cognitive empathy). In Study 1 (<i>N</i> = 530), we compared childless men, expecting fathers, and fathers. Expecting fathers displayed greater affective empathy toward children than childless men, but they did not differ significantly from fathers. Unexpectedly, fathers exhibited lower cognitive empathy than expecting fathers. Study 2 (<i>N</i> = 516) extended these findings by investigating the impact of different levels of fathering experience among first-time fathers and those with prior parenting experience. Fathers of infants showed more affective empathy than childless men, regardless of prior parenting experience. Fathers with older children had lower cognitive empathy compared to childless men and fathers with infants. These results suggest that expecting fathers and fathers with a new infant may exhibit increased affective empathy to children's emotions. More experienced fathers and fathers of older children may have become accustomed to childcare, necessitating less intensive engagement to child signals. Future longitudinal studies are needed to determine whether empathy toward children's emotions shows within-person fluctuations during the transition to fatherhood instead of steadily increasing.

However, the relationship between emotions and performance is not always straightforward. For instance, when positive emotions become too intense, they can harm cognitive performance. Do people's lay theories of emotions capture this complex relationship between emotions and performance? If so, how early in development do children grasp this nuanced relationship? In three preregistered experiments, we explored children's and adults' beliefs about the impact of different emotional states on attention in school. In Study 1a, we found that 5- to 7-year-old Canadian children (<i>N</i> = 90) and North American adults (<i>N</i> = 55) strongly predicted that happy characters would be better at paying attention in school compared to sad characters, but only adults predicted better attention for a mildly happy character compared to a very happy one. Study 1b (<i>N</i> = 60) shows that adults' intuitions about intense positive emotions as suboptimal for attentional tasks apply equally to child and adult characters. In Study 2, we found that children (<i>N</i> = 80) perceive that the effect of intensity depends on the emotion's valence-it compounds the adverse effects of sadness and amplifies the benefits of happiness. Conversely, adults (<i>N</i> = 80) believe strong emotions, regardless of their valence, are not ideal for paying attention in school. Together, our findings show a developing appreciation of the impact of emotional intensity on cognitive performance-an important aspect of children's emotion understanding with likely implications for self-regulated learning.

To explore early antecedents of this gender imbalance, the present study investigated the developmental changes in children's social preference of boys and girls who pursue brilliance-required (vs. effort-required) activities. Importantly, we took an intersectional perspective to explore whether children consider target race in their social preference. Five- to 9-year-old U.S. children (<i>N</i> = 207; <i>M</i>_age = 7.53; 104 girls and 103 boys; 48% White) were presented with pairs of Asian, Black, and White characters matched in gender. One character was depicted as enjoying a game requiring high intellectual talents and the other enjoyed a game requiring effort. Participants were then asked to choose the character that they liked more, as an indicator of their social preference. With age, children became increasingly likely to prefer White boys and girls of color (i.e., Black and Asian girls) pursuing activities requiring brilliance (vs. activities requiring effort). In contrast, children did not develop increasing social preference for White girls or boys of color who opt in for brilliance-required activities. Our data suggest that, as early as elementary school years, children's social preference in contexts valuing sheer brilliance becomes both gendered and racialized. These findings highlight the importance of using an intersectional approach to identify the specific developmental processes that contribute to social disparities in brilliance-required contexts.

Prior studies have uncovered behavioral and neural correlates of statistical learning, yet additional work is needed from low- and middle-income countries to explore whether statistical learning varies across cultures or underlies associations often found between socioeconomic status (SES) and language outcomes. In the present study, we explored the feasibility of using functional near-infrared spectroscopy (fNIRS) to explore auditory statistical learning in Bangladesh, a lower-middle-income country. Participants were 102 2-year-old (<i>M</i> = 25.72 months, <i>SD</i> = 2.07 months) and 125 5-year-old children (<i>M</i> = 62.35 months, <i>SD</i> = 2.46 months) living in a low-income urban neighborhood of Dhaka (average family income of 28,145.13 Bangladeshi Takas or 260.06 U.S. dollars per month). We also collected measures of SES and language outcomes. Brain responses during the statistical learning paradigm could be detected with fNIRS in both two- and 5-year-olds, with 2-year-olds exhibiting a higher response to predictable sequences and 5-year-olds exhibiting higher responses to unpredictable sequences. fNIRS correlates of statistical learning were not related to language outcomes but were associated with SES in the 5-year-old cohort. This study demonstrates the utility of employing fNIRS to study the neural correlates of statistical learning in low- and middle-income countries and the feasibility of expanding the representativeness of the existing literature. These findings also highlight potential areas for inquiry into how SES may relate to individual differences in statistical learning responses.

For example, it is uncertain if EFs applied in the context of domain-specific mathematical cognition (i.e., EFs applied while processing numbers) are more closely related to mathematics achievement than EFs applied in nonnumerical, domain-general contexts. Also, how distinct EF domains-that is, working memory, inhibitory control, and cognitive flexibility-and contents-that is, numerical versus nonnumerical-moderate the association between magnitude processing and mathematics achievement has not been fully understood. To address these issues, we investigated how magnitude processing, EFs applied to nonnumerical and numerical task stimuli, and their interactions were associated with mathematics achievement. Three hundred fifty-nine Brazilian third- to fifth-grade (8-10 years old) students completed measures of working memory, inhibitory control, and cognitive flexibility with numerical and nonnumerical task versions, nonsymbolic and symbolic magnitude comparison, and mathematics achievement. A series of regression models indicated that nonsymbolic and symbolic magnitude processing are consistently associated with mathematics achievement, even when controlling for working memory, inhibitory control, and cognitive flexibility measured with both numerical and nonnumerical contents. All EF measures were associated with mathematics achievement. However, cognitive flexibility measured with numerical content showed the strongest association. Results support the hypothesis that magnitude processing and EFs are uniquely associated with mathematics achievement. Furthermore, EFs measured with nonnumerical and numerical contents related differently to mathematics achievement, even when controlling for symbolic and nonsymbolic magnitude processing, suggesting they encompass somewhat distinct cognitive processes.
