The parental investment conflict considers the question of how much each sex should invest in each brood, thereby characterizing different animal species. Each species usually adopts a certain parental care pattern: female-care only, male-care only, biparental care, or even no parental care at all. The differences in care patterns are usually explained by the different costs and benefits arisin...

a r t i c l e i n f o Keywords: Intergenerational conflict Sexual selection Parental resource distribution Theoretical model Direct versus indirect benefits Mate preference evolution Arranged marriage Good parent In human societies, parents often have a strong influence on the mate choice of their offspring. Moreover, empirical studies show that conflict over mate choice between parents and off...

Prior work has suggested that inter-parental conflict likely plays an etiological role in child behavior problems. However, family-level measurement of inter-parental conflict in most traditional child twin studies has made it difficult to tease apart the specific causal mechanisms underlying this association. The Children's Perception of Inter-parental Conflict scale (CPIC) provides a child-sp...

BACKGROUND Depression is a major health concern for college students due to its substantial morbidity and mortality. Although low parental education has been identified as a factor in depression in college students, the mechanisms through which parental educational achievement affects students' depression are not well understood. We tested whether adverse family and college environments mediate...

In mammals and in plants, parental genome dosage imbalance deregulates embryo growth and might be involved in reproductive isolation between emerging new species. Increased dosage of maternal genomes represses growth while an increased dosage of paternal genomes has the opposite effect. These observations led to the discovery of imprinted genes, which are expressed by a single parental allele. ...

Adolescents develop within multiple contexts that synergistically influence their behavior and health. To understand the simultaneous influence of neighborhood and family contexts on adolescents, this study examined relationships of neighborhood socioeconomic disadvantage, neighborhood social disorganization, family conflict, parent-child bonding and parental control with trajectories of physic...

In a sample of low-income families (N = 239), structural equation models assessed predictors of fathers' involvement with preschool-aged children in instrumental, behavioral, and emotional realms. Results suggest that parental conflict has a strong negative relation with father involvement. Fathers' human capital characteristics, healthy psychosocial functioning, and past stability in family re...

OBJECTIVE To examine associations of parent-adolescent relationship quality (parental acceptance and parent-adolescent conflict) with adolescent type 1 diabetes management (adherence and metabolic control) and depressive symptoms in Latinos and Caucasians. METHODS In all, 118 adolescents and their mothers (56 = Latino, 62 = Caucasian) completed survey measures of parental acceptance, diabetes...

The aim of this study was to explore the association between parental separation during childhood (up to 18 years of age) and cardiometabolic risk factors (body mass index, fat mass index, blood pressure, physical activity, smoking, and alcohol consumption) in late adolescence using a cross-cohort comparison and to explore whether associations differ according to the age at which the parental s...

In species with biparental care, sexual conflict occurs because the benefit of care depends on the total amount of care provided by the two parents while the cost of care depends on each parent's own contribution. Asynchronous hatching may play a role in mediating the resolution of this conflict over parental care. The sexual conflict hypothesis for the evolution of asynchronous hatching sugges...
