  1. Some children socially transition genders by changing their pronouns (and often names, hairstyles, and clothing) from those associated with their assigned sex at birth to those associated with their gender identity. We refer to children who have socially transitioned as transgender children. Using a prospective sample of children who socially transitioned during childhood (at or before the age of 12; age of transition: M = 6.82 years), we tested whether the parent-reported internalizing symptoms of transgender children were different before versus after they socially transitioned. The children were predominantly White (70.6% White) and girls (76.5% transgender girls, 23.5% transgender boys). Their parents tended to have high levels of education (74.5% bachelor’s degree or above) and lived in families with high household incomes (62.7% with household incomes of $75,000 or above). On average, youths showed lower levels of internalizing symptoms after socially transitioning versus before, suggesting a possible mental-health benefit of these transitions.

  2. Abstract

    The development of selective visual attention is critical for effectively engaging with an ever-changing world. Its optimal deployment depends upon interactions between neural, motor, and sensory systems across multiple timescales and neurocognitive loci. Previous work illustrates the spatio-temporal dynamics of these processes in adults, but less is known about this emergent phenomenon early in life. Using data (n = 190; 421 visits) collected between 3 and 35 months of age, we examined the spatio-temporal complexity of young children’s gaze patterns as they viewed stimuli varying in semantic salience. Specifically, we used detrended fluctuation analysis (DFA) to quantify the extent to which infants’ gaze patterns exhibited scale invariant patterns of nested variability, an organizational feature thought to reflect self-organized and optimally flexible system dynamics that are not overly rigid or random. Results indicated that gaze patterns of even the youngest infants exhibited fractal organization that increased with age. Further, fractal organization was greater when children (a) viewed social stimuli compared to stimuli with degraded social information and (b) when they spontaneously gazed at faces. These findings suggest that selective attention is well-organized in infancy, particularly toward social information, and indicate noteworthy growth in these processes across the first years of life.

  3. Income, education, and cumulative‐risk indices likely obscure meaningful heterogeneity in the mechanisms through which poverty impacts child outcomes. This study draws from contemporary theory to specify multiple dimensions of poverty‐related adversity and resources, with the aim of better capturing these nuances. Using data from the Family Life Project (N = 1,292), we leveraged moderated nonlinear factor analysis (Bauer, 2017) to establish group‐ and longitudinally invariant environmental measures from infancy to early adolescence. Results indicated three latent factors—material deprivation, psychosocial threat, and sociocognitive resources—were distinct from each other and from family income. Each was largely invariant across site, racial group, and development and showed convergent and discriminant relations with age‐twelve criterion measures. Implications for ensuring socioculturally valid measurements of poverty are discussed.
