Multi-modal MRI data analysis can be used to predict a child or young adult's age. Most, but not all, individuals' brain-derived age estimate is close to their chronological age.

purpose : to report two young patients with unilateral pseudoexfoliation (pex) syndrome case reports : two young patients with pex syndrome were examined. the first was a 30-year-old woman who had a history of penetrating ocular trauma with iris prolapse in the right eye that subsequently developed pex material deposition on pupillary border and anterior lens capsule. the second was a 13-year-o...

Mother-daughter relationships are generally characterized by frequent contact and high levels of regard. Yet little is known about what mothers and daughters find enjoyable about their contact. Forty-eight pairs of older mothers (M = 76 years) and their middle-aged daughters (M = 46 years) and 44 pairs of middle-aged mothers (M = 47 years) and their young adult daughters (M = 21 years) (N = 182...

Heritability estimates based on two small studies in children indicate that the genetic contribution to individual differences in loneliness is approximately 50%. Heritability estimates of complex traits such as loneliness may change across the lifespan, however, as the frequency, duration, and range of exposure to environmental influences accrues, or as the expression of genetic factors change...

A lmost one million teenagers in the United States become pregnant each year (“Facts in Brief”), and these same teens’ ideas about sex and related matters are strongly influenced by the media. Young adult novels about teen pregnancy can speak to teens who “want to read about things that are interesting and true” (Donelson and Nilsen 87). These same teens also read young adult literature to “fin...

Due to the success of antiretroviral (ART) medications, young people living with perinatally acquired HIV (PHIV+) are now surviving into adolescence and young adulthood. Understanding factors influencing ART non-adherence in this group is important in developing effective adherence interventions. Most studies of ART adherence in HIV-positive populations assess differences in adherence levels an...

This study provides further evidence that the time-of-day (TOD) when testing is conducted affects cognitive performance in old rats and, for the first time in an animal model, in young adult rats as well. Groups of young and old rats were entrained to a 12-h light-dark schedule and administered tests of learning and memory in a non-matching-to-sample (NMTS) task in a water maze. Testing was con...

Background and aims Recent research on problematic Facebook use has highlighted the need to develop a specific theory-driven measure to assess this potential behavioral addiction. The aim of the present study was to examine the factorial validity of the Problematic Facebook Use Scale (PFUS) adapted from Caplan's Generalized Problematic Internet Scale model. Methods A total of 1,460 Italian adol...

PURPOSE Athlete's report of concussion symptoms to coaching or medical personnel is an important component of concussion risk reduction. This study applies a model based on the Theory of Planned Behavior (TPB) to the prediction of concussive symptom underreporting among late adolescent and young adult male ice hockey players. METHODS Participants were members of an American Tier III Junior A ...

Despite the attainment of several adult cranial dimensions relatively early in childhood, skeletal maturity and, by consequence, adult form are typically defined by the eruption of the third molars around 17 years of age. This in turn serves as the division between subadults and adults, which is then applied to population studies of biological variation. Specifically, comparative data sets of a...
