Growing up with multiple siblings might negatively affect language development. This study examined the associations between birth order, sibling characteristics and parent-reported vocabulary size in 6163 Norwegian 8- to 36-month-old children (51.4% female). Results confirmed that birth order was negatively associated with vocabulary, yet…

Children's evaluations of empathizers were examined using vignette-based tasks (N = 159 4- to 7-year-old U.S. children, 82 girls, 52% White) between March 2023 and March 2024. Children typically evaluated empathizers positively compared to less empathic others. They rated empathic responses as more appropriate, selected empathizers as nicer, and…

Australian children aged 6-9 years (N = 120, 71 females; data collected in 2021-2022) were tasked with remembering the locations of 1, 3, 5, and 7 targets hidden under 25 cups on different trials.

The results show that older children…

This study investigated the development of educational aspirations (EAs) among Chinese youth (n = 2228, 48.61% female, 87.66% Han, M[subscript age_2010] = 11.48 years) for 6 years. Five latent classes of EA trajectories were identified. They varied greatly during early adolescence but converged around an associate degree in middle adolescence and…

Theoretical work has suggested close associations between morphological awareness (MA) and reading skills in Chinese; however, the nature and direction of these time-ordered links are little known. This study examined the interplays of MA and reading skills using a continuous-time modeling approach to three waves of two-year longitudinal data from…

This longitudinal study examined age- and gender-related differences in autobiographical memory about the COVID-19 pandemic lockdowns and whether the content of these memories predicted psychological adjustment over time.

Children with disabilities often receive accommodations, but teachers rarely explain them to typically-developing (TD) classmates. How do TD students reason about these accommodations and evaluate their fairness? Five-, seven-, and nine-year-olds from the United States (N = 122; 50% female; 87.7% white; data collected April 2022-September 2023)…
