Objective: The study examined how the interplay between maternal ADHD symptoms and maternal inhibitory control and child ADHD is related to parenting behaviors. Method: The sample included 141 mothers and their 8- to 12-year-old children, 61 children with ADHD and 80 without. Parenting was measured using self-reports (i.e., overreactive and lax parenting) and observation (i.e., negative and supportive parenting). Maternal inhibitory control was measured using a neurocognitive task. Hierarchical multiple regressions were conducted to predict parenting, controlling for child sex, conduct behaviors, and parenting distress. Results: Interactions between maternal ADHD symptoms and maternal inhibitory control suggested that hyperactive–impulsive symptoms were linked to parenting negativity only when inhibitory control was low, and maternal inattention symptoms were related to lax parenting only when maternal inhibitory control was high or when children did not have ADHD. Conclusion: Results indicate the importance of maternal regulation processes in the mechanisms linking maternal ADHD with parenting.

Maternal Regulation

In self-compatible plants, the reduction in brood size may be caused either by inbreeding depression, resource limitation, maternal regulation of offspring quality, or by sibling rivalry. We studied seed abortion in Caryocar brasiliense Camb. (Caryocaraceae), a Neotropical tree species, to verify whether seeds sired by self-pollination are aborted. Fruits were sampled from 23 mother trees to estimate seed set and proportion of aborted seeds. Ripened and aborted seeds from 18 mother trees were genotyped using 10 microsatellite loci together with mother trees and all nearby adults (83 adults) to determine the pollen donor by assignment test. From the 541 seeds, 190 were aborted and the mean number of aborted seeds per fruit was 0.627 (SD = 0.807). Proportion of aborted seeds was different among mother trees and among fruits within mother trees. All but three aborted seeds were sired by self-pollination and selfed seeds were aborted in fruits harbouring both selfed and outcrossed seeds. Aborted outcrossed seeds were sired by pollen donors closely related to mother trees. Our results strongly support that seed abortion in C. brasiliense may be the outcome of inbreeding depression and sibling rivalry when selfed and outcross pollinated ovules compete.
