Emerging evidence has demonstrated that paternal alcohol use can modify the behavior of offspring, particularly male offspring. However, preclinical studies to date have not used voluntary self-administration of alcohol to examine alcohol-related behaviors in offspring. Here, we tested the hypothesis that paternal alcohol self-administration followed by punishment-imposed abstinence alters alco...

In a number of species, males are cannibalized by females after mating (reviewed in [1, 2]), and some males actually appear to facilitate their own cannibalism (reviewed in [3]). Such self-sacrifice can evolve if being eaten sufficiently enhances either fertilization success (mating effort) or offspring number or fitness (paternal effort). While there is some support for the mating-effort hypot...

Hormones associated with pregnancy and parturition have been implicated in facilitating the onset of maternal behavior via reductions in neophobia, anxiety, and stress responsiveness. To determine whether the onset of paternal behavior has similar associations in biparental male California mice (Peromyscus californicus), we compared paternal responsiveness, neophobia (novel-object test), and an...

Although the effects of paternal alcoholism on the psychosocial adjustment of children are well documented, the impact of fathers' illicit drug abuse on their children is poorly understood. The purpose of this study was to compare the adjustment of children living in families with drug-abusing fathers (n = 40) with that of children with fathers who abused alcohol (n = 40) and children with non-...

Research finds that children who have experienced the incarceration of a parent exhibit higher levels of antisocial behavior. Yet there are reasons to question whether this association is in fact causal, and research that empirically pins down mechanisms that explain any observed association is in high demand. We attempt to better account for unobserved heterogeneity by using children with fath...

The unique and interactive effects of paternal and maternal alcohol problems on the drinking behavior of adolescent girls and boys were investigated. A prospective design was employed to examine changes in youth drinking behavior over a 3-year period in a community-based sample of 695 families. Results revealed that, as maternal alcohol problems increased, the likelihood of adolescent alcohol u...
