Understanding of preterm infant cognitive competences across the first year of life is limited regarding the developmental constructs of continuity, stability, coherence, and predictive validity as well as how they manifest by age and country of origin. This prospective longitudinal study examined and compared mean-level continuity,…

Theorized mechanisms linking views on aging, self-regulation, and well-being have not previously been examined longitudinally. This study considers goal re-engagement as a potential mediator of longitudinal relationships between awareness of age-related change (AARC) and vitality. We expected that more positive perceptions of aging (i.e., higher…

Children prenatally exposed to opioids exhibit impairments in cognitive functioning and have an increased likelihood of experiencing other forms of adversity. Given that these other forms of early life adversity are linked to lower levels of cognitive functioning, it is important to determine whether the association between opioid exposure and…

Maternal education is associated with early child outcomes. However, the several mechanisms that may explain this relationship remain underexplored. Using data from 1,097 children aged 12-15 months in Chile, we estimate the maternal education gap across child cognitive and language outcomes. Following a bioecological perspective, we explore…

First-order theory of mind (ToM) development has shown to conform to a Guttman scale, with desire reasoning developing before belief reasoning. There have been attempts to test for internal consistency and scalability in advanced ToM, but not over a broad age range and only with a limited set of tasks. This 2-year longitudinal study (N = 155;…
