TEXTO PARA A QUESTÃO
A study carried out by Lauren Sherman of the
University of California and her colleagues investigated how
use of the “like” button in social media affects the brains of
teenagers lying in body scanners.
Thirty-two teens who had Instagram accounts were
asked to lie down in a functional magnetic resonance
imaging (fMRI) scanner. This let Dr. Sherman monitor their
brain activity while they were perusing both their own
Instagram photos and photos that they were told had been
added by other teenagers in the experiment. In reality, Dr.
Sherman had collected all the other photos, which included
neutral images of food and friends as well as many depicting
risky behaviours like drinking, smoking and drug use, from
other peoples’ Instagram accounts. The researchers told
participants they were viewing photographs that 50 other
teenagers had already seen and endorsed with a “like” in the
laboratory.
The participants were more likely themselves to “like”
photos already depicted as having been “liked” a lot than
they were photos depicted with fewer previous “likes”. When
she looked at the fMRI results, Dr. Sherman found that
activity in the nucleus accumbens, a hub of reward circuitry
in the brain, increased with the number of “likes” that a
photo had.
