Teens: This is how social media affects your brain — Prevent Child Abuse Delaware

Reward circuitry In a recent study, researchers at the UCLA brain mapping center used an fMRI scanner to image the brains of 32 teenagers as they used a bespoke social media app resembling Instagram. "When teens learn that their own pictures have supposedly received a lot of likes, they show significantly greater activation in parts of the brain's reward circuitry," says lead author Lauren Sherman. The teenagers were shown more than 140 images where 'likes' were believed to from their peers, but were in fact assigned by the research team. Peer influence Social learning.

The study, published online in the journal Pediatrics, found 0.6 percent of 10-year-olds, 1.1 percent of 11-year-olds and 2.4 percent of 12-year-olds said they had sex. However, sex among very young adolescents was frequently involuntary, the study found. The study also found 33 percent of those age 16, about half of those age 17, 61 percent of 18-year-olds and 71 percent of 19-year-olds said they have had sex -- a pattern that has prevailed for decades.

Only 16% of teens have had sex by age 15, compared with one-third of those aged 16, nearly half (48%) of those aged 17, 61% of 18-year-olds and 71% of 19-year-olds.[1] There is little difference by gender in the timing of first sex. •On average, young people have sex for the first time at about age 17, [2] but they do not marry until their mid-20s.[3] This means that young adults may be at increased risk for unintended pregnancy and STIs for nearly a decade or longer.
