Development of male proactive and reactive physical aggression during adolescence.
BACKGROUND Different developmental courses have been postulated for proactive and reactive aggression. OBJECTIVE Investigated the developmental course of proactive and reactive aggression in a large sample of adolescent boys from low socioeconomic areas. METHOD A dual group-based joint trajectory method was used to identify distinct trajectories as well as similarities and differences in in...
متن کاملScent may signal fighting ability in male Iberian rock lizards.
Intrasexual competition favours the evolution of conspicuous fighting ability badges. However, in spite of the fact that chemoreception is important in sexual selection of many animals, such as lizards, the role of chemical signals in males' contests is relatively unknown. Here, we show that proportions of cholesterol in femoral gland secretions of male Iberian rock lizards were related to thei...
متن کاملCardiac Inter-Beat Interval Complexity Is Influenced By Physical Activity
The complexity of physiological signals may be a more sensitive indicator of health than standard or average measurements. We examined cardiac inter-beat intervals of healthy subjects who are either physically active or sedentary to determine whether measures of complexity are more sensitive to subtle cardiac changes than standard measures. Subjects were pre-screened by self-report, and qualify...
متن کاملLethal Fighting in Nematodes Is Dependent on Developmental Pathway: Male-Male Fighting in the Entomopathogenic Nematode Steinernema longicaudum
Aggressive encounters occur between competitors (particularly males) throughout the animal kingdom, and in some species can result in severe injury and death. Here we describe for the first time lethal interactions between male nematodes and provide evidence that the expression of this behaviour is developmentally controlled. Males of the entomopathogenic nematode Steinernema longicaudum coil a...
متن کاملBrain plasticity and intellectual ability are influenced by shared genes.
Although the adult brain is considered to be fully developed and stable until senescence when its size steadily decreases, such stability seems at odds with continued human (intellectual) development throughout life. Moreover, although variation in human brain size is highly heritable, we do not know the extent to which genes contribute to individual differences in brain plasticity. In this lon...
