Abstract
Prenatal tobacco exposure (PTE) and tobacco-cannabis coexposure (PTCE) co-occur with negative maternal emotional functioning (termed prenatal risks) and together increase risk for child regulatory problems at early school age (ESA). Little is known about developmental processes in early childhood that may mediate this association. We examined two hypothesized mediational processes linking prenatal risks to ESA emotion regulation (ER) and lability-negativity; parasympathetic functioning at toddler age and chronic risk reflected by continued postnatal maternal negative emotional functioning (i.e., depression, anger/hostility, and emotion dysregulation) and substance exposure. Congruent with differential susceptibility theory, we examined interactions between sensitive parenting and toddler parasympathetic functioning predicting ESA ER. Finally, we explored the role of child sex as a moderator. Mothers (N = 247; 53% male infants; 51% Black, 31% White, 19% Hispanic, and 8% other or mixed race) were recruited in the first trimester of pregnancy into one of three groups: PTE (n = 81), PTCE (n = 97), and no substance exposure (n = 69) matched on age and education. Substance exposure was assessed using multiple methods, maternal negative emotional functioning via self-reports, parenting with observations, and child ER using teacher, maternal, and lab assessor reports. Results supported a chronic risk pathway with less support for a parasympathetic pathway. Toddlers who demonstrated respiratory sinus arrhythmia withdrawal to frustration were susceptible to the positive context of sensitive parenting in predicting higher ER. Results emphasize the importance of chronicity of postnatal risks including substance exposure and evaluating the differential impact of positive environments for children with substance exposure.

期刊介绍：
Developmental Psychology ® publishes articles that significantly advance knowledge and theory about development across the life span. The journal focuses on seminal empirical contributions. The journal occasionally publishes exceptionally strong scholarly reviews and theoretical or methodological articles. Studies of any aspect of psychological development are appropriate, as are studies of the biological, social, and cultural factors that affect development. The journal welcomes not only laboratory-based experimental studies but studies employing other rigorous methodologies, such as ethnographies, field research, and secondary analyses of large data sets. We especially seek submissions in new areas of inquiry and submissions that will address contradictory findings or controversies in the field as well as the generalizability of extant findings in new populations. Although most articles in this journal address human development, studies of other species are appropriate if they have important implications for human development. Submissions can consist of single manuscripts, proposed sections, or short reports.
