Parent-offspring conflict theory suggests that the reproductive interests of parents and children may conflict when parents want to have another child and an existing child wants continued parental attention and resources. This conflict leads toddlers to throw temper tantrums and use other psychological weapons to maintain parental investment. Few studies employing this theory have considered b...

OBJECTIVE To examine family conflict, parental blame, and poor family cohesion as predictors of treatment outcome for youths receiving family-focused cognitive behavioral therapy (FCBT) for obsessive-compulsive disorder (OCD). METHOD We analyzed data from a sample of youths who were randomized to FCBT (n = 49; 59% male; M age = 12.43 years) as part of a larger randomized clinical trial. Youth...

Parent-offspring conflict is predicted to occur because offspring will demand more parental investment than is optimal for the parent, and is said to be strongest during weaning when parents reduce nursing while offspring continue to demand parental care. While weaning conflict has been shown to be stressful in offspring, little is known about the effects of weaning conflict on mothers. We hypo...

Parent-offspring conflict (POC) theory is an interesting conceptual framework for understanding the dynamics of parental care. However, this theory is not easy to test empirically, as exact measures of parental investment in an experimental set-up are difficult to obtain. We have used free-ranging dogs Canis familiaris in India, to study POC in the context of extended parental care. We observed...

Parental conflicts can lead to antagonistic coevolution of the sexes and of parental genomes. Within a population, the resulting antagonistic effects should balance, but crosses between populations can reveal conflict. Parental conflict is less intense in self-pollinating plants than in outcrossers because outcrossing plants are pollinated by multiple pollen donors unrelated to the seed parent,...

Vertebrates display a wide variety of parental care behaviours, including the guarding of offspring pre and post nutritional independence as well as the direct provision of nutrients during the early development period. The Amazonian cichlid Symphysodon spp. (discus fish) is unusual among fish species, in that both parents provide offspring with mucus secretions to feed from after hatching. Thi...

The differential effects of parental divorce and marital conflict on young adult children’s romantic relationships were examined in this short-term longitudinal study. Using a sample of 285 young adults, structural equation modeling supported the hypothesis that parental divorce and marital conflict were independently associated with young adult children’s romantic relationships through differe...

Existing models of parental investment have mainly focused on interactions at the level of the family, and have paid much less attention to the impact of population-level processes. Here we extend classical models of parental care to assess the impact of population structure and limited dispersal. We find that sex-differences in dispersal substantially affect the amount of care provided by each...

Parental regulation of children's smartphone use is typically associated with conflict. To explain conflict, this paper focused on parents' own use. A panel survey among parent-child pairs (NTme2 = 384) revealed that excessive at Time 1 was a lack control over 2. Lack use, in turn, related to conflict about the from and perspectives time. The relations were independent whether parents thought s...
