Social Media Use Is Linked to Brain Changes in Teens, Research Finds
The effect of social media use on children is a fraught area of research, as parents and policymakers try to ascertain the results of a vast experiment already in full swing. Successive studies have added pieces to the pu zzle, fleshing out the implications of a nearly constant stream of virtual interactions beginning in childhood.
A new study by neuroscientists at the University of North Carolina tries something new, conducting successive brain scans of middle schoolers between the ages of 12 and 15, a period of especially rapid brain development.
The researchers found that children who habitually checked their social media feeds at around age 12 showed a distinct trajectory, with their sensitivity to social rewards from peers heightening over time. Teenagers with less engagement in social media followed the opposite path, with a declining interest in social rewards.
The study has important limitations, the authors acknowledge. Because adolescence is a period of expanding social relationships, the brain differences could reflect a natural pivot toward peers, which could be driving more frequent social media use.
“We can’t make causal claims that social media is changing the brain,” said Eva H. Telzer, an associate professor of psychology and neuroscience at the University of North Carolina, Chapel Hill, and one of the authors of the study.
But, she added, “teens who are habitually checking their social media are showing these pretty dramatic changes in the way their brains are responding, which could potentially have long-term consequences well into adulthood, sort of setting the stage for brain development over time.”
A team of researchers studied an ethnically diverse group of 169 students in the sixth and seventh grades from a middle school in rural North Carolina, splitting them into groups according to how often they reported checking Facebook, Instagram and Snapchat feeds.
At around age 12, the students already showed distinct patterns of behavior. Habitual users reported checking their feeds 15 or more times a day; moderate users checked between one and 14 times; nonhabitual users checked less than once a day.
The subjects received full brain scans three times, at approximately one-year intervals, as they played a computerized game that delivered rewards and punishment in the form of smiling or scowling peers. While carrying out the task, the frequent checkers showed increasing activation of three brain areas: reward-processing circuits, which also respond to experiences like winning money or risk-taking behavior; brain regions that determine salience, picking out what stands out in the environment; and the prefrontal cortex, which helps with regulation and control.
The results showed that “teens who grow up checking social media more often are becoming hypersensitive to feedback from their peers,” Dr. Telzer said. Social sensitivity could be adaptive, showing that the teenagers are learning to connect with others; or it could lead to social anxiety and depression if social needs are not met.
“They are showing that the way you use it at one point in your life does influence the way your brain develops, but we don’t know by how much, or whether it’s good or bad,” said Jeff Hancock, the founding director of the Stanford Social Media Lab, who was not involved in the study. He said that many other variables could have contributed to these changes. He described the paper as “a very sophisticated piece of work,” contributing to research that has emerged recently showing that sensitivity to social media varies from person to person.
Over the last decade, social media has remapped the central experiences of adolescence, a period of rapid brain development. Researchers have documented a range of effects on children’s mental health. Some studies have linked use of social media with depression and anxiety, while others found little connection.
Without more information about other aspects of the students’ lives, “it is challenging to discern how specific differences in brain development are to social media checking,” said Adriana Galvan, a specialist in adolescent brain development at the University of California Los Angeles, who was not involved in the study.
Dr. Telzer, one of the study’s authors, described the rising sensitivity to social feedback as “neither good nor bad.” “It’s helping them connect to others and obtain rewards from the things that are common in their social world, which is engaging in social interactions online,” she said. This is the new norm,” she added. “Understanding how this new digital world is influencing teens is important. It may be associated with changes in the brain, but that may be for good or for bad. We don’t necessarily know the long-term implications yet.”

Atente para os seguintes excertos do Manifesto Comunista de Marx e Engels, de 1848.
“Ao invés das antigas necessidades, satisfeitas pelos produtos nacionais, surgem novas demandas, que reclamam para a sua satisfação os produtos das regiões mais longínquas e de climas os mais diversos. No lugar do antigo isolamento de regiões e nações autossuficientes, desenvolvem-se um intercâmbio universal e uma universal interdependência das nações.
[...]
Com o desenvolvimento da burguesia, isto é, do capital, desenvolve-se também o proletariado, [...], os quais só vivem enquanto têm trabalho e só têm trabalho enquanto o seu trabalho aumenta o capital. Esses operários, constrangidos a vender-se a retalho, são mercadoria, artigo de comércio como qualquer outro; em consequência, estão sujeitos a todas as vicissitudes da concorrência, a todas as flutuações do mercado”.

Os trechos acima tratam, respectivamente, dos seguintes fenômenos sociais ainda atuais:
A concepção de uma “nacionalidade mestiça” brasileira, de modo geral, considera que o povo aqui surgiu historicamente do cruzamento de três raças (o europeu, o índio e o africano), mas, depois desse momento inicial, os brasileiros já não são mais portugueses/europeus, nem africanos e nem índios, mas um “povo novo”, resultado desse cadinho de raças diferentes do passado colonial. Porém, esta concepção de que o povo brasileiro é mestiço carrega consigo, por outro lado, um discurso ideológico que estabelece a ideia de unidade nacional e esconde o racismo e as contradições étnico-raciais historicamente constituídas e ainda presentes na sociedade atual, além de amenizar a pauta pública nacional sobre as reivindicações dos povos e populações tradicionais no país.
Considerando o enunciado acima, atente para o que se afirma a seguir e assinale com V o que for verdadeiro e com F o que for falso.
( ) Pensar que no Brasil de hoje todos somos mestiços resulta em um pensamento que exclui da história as matrizes étnico-raciais indígena e negra na formação da nação, considerando apenas os portugueses.
( ) A principal consequência da ideia da mestiçagem é a de comprovar que, no Brasil, há de fato uma democracia racial que promove uma sociedade sem falsas contradições uma vez que todos são brasileiros.
( ) A concepção de uma “mestiçagem brasileira” pode esconder as lutas políticas por direitos e ações afirmativas das pessoas negras, das comunidades quilombolas e dos povos tradicionais indígenas.
( ) Imaginar que o brasileiro é mestiço e não mais branco, negro ou índio prejudica o reconhecimento de que a sociedade brasileira é composta pela diversidade étnico-racial e pelo multiculturalismo.
A sequência correta, de cima para baixo, é:
O ChatGPT é uma tecnologia de inteligência artificial (IA) que foi lançada no final de 2022 e é basicamente um robô virtual (chatbot) que responde a perguntas variadas e pode redigir uma gama considerável de textos dos mais variados tipos e modelos, por exemplo: redações, procurações judiciais, poesias, artigos acadêmicos, matérias jornalísticas e, mesmo, questões de vestibulares. Apesar da euforia com as possibilidades desta IA, a ameaça de disrupção já paira sobre trabalho e emprego. Campos que dependem do texto, como o jornalismo, poderão ser largamente modificados — e vagas poderão sumir para sempre. A competência do ChatGPT em gerar códigos também já provoca questionamentos em um setor relativamente novo: a programação. Mas, uma das áreas que vêm percebendo desde já o potencial de problemas do ChatGPT é justamente uma das mais afetadas pela chegada de novas tecnologias: a educação.

Partindo do exposto, assinale a proposição verdadeira.
Para Nancy Fraser, cientista social norte-americana, as reivindicações dos movimentos sociais por justiça social, a partir do final do século XX, passaram a dividir-se em dois tipos: as reivindicações redistributivas e as de reconhecimento. O primeiro tipo de reivindicações pretende buscar uma distribuição mais justa de recursos materiais e riquezas dentro de uma sociedade. As reivindicações do tipo reconhecimento traçam metas, no geral, que visam, dentre outros fins, a uma sociedade onde se acolha amistosamente as diferenças sociais e culturais.
Considerando esses tipos de reivindicações dos movimentos sociais, avalie as proposições a seguir:
I. O Movimento dos Trabalhadores Sem Terra (MST) e o Movimento dos Trabalhadores Sem Teto (MTST), no Brasil, fazem parte do tipo de reivindicações redistributivas.
II. O Occupy Wall Street, de 2011, produziu uma reivindicação do tipo reconhecimento nesse distrito financeiro dos EUA, pois lutava contra a disparidade socioeconômica.
III. As organizações dos movimentos negro, feminista e LGBTQIAP + produzem reivindicações redistributivas uma vez que lutam contra discriminações e por igualdade de direitos.
IV. As reivindicações das pessoas com deficiência são do tipo reconhecimento considerando-se que buscam pela inclusão social e por tratamento justo em ambientes como empresas e escolas.
É correto o que se afirma somente em
Leia com atenção a seguinte citação:
“É no plano político que a razão, na Grécia, primeiramente se exprimiu, constituiu-se e formou-se. A experiência social pôde tornar-se entre os gregos o objeto de uma reflexão positiva, porque se prestava, na cidade, a um debate público de argumentos. O declínio do mito data do dia em que os primeiros sábios puseram em discussão a ordem humana, procuraram defini-la em si mesma, traduzi-la em fórmulas acessíveis à sua inteligência, aplicar-lhe a norma do número e da medida”.
VERNANT, Jean-Pierre. As origens do pensamento grego. – 2ª ed.
Rio de Janeiro; São Paulo: Difel, 1977, p. 42.
Considerando a passagem acima, assinale a opção que corresponde à explicação da tese de Jean-Pierre Vernant de que a filosofia “é filha da pólis”.
Em junho de 1996, organizações não governamentais reuniram-se em Barcelona (Espanha), sob o patrocínio da UNESCO, e elaboraram a Declaração Universal dos Direitos Linguísticos. Em sua Introdução, esse documento estabelece, como uma das considerações que lhe serve de base, que “a invasão, a colonização e a ocupação, assim como outros casos de subordinação política, econômica ou social, implicam frequentemente a imposição direta de uma língua estrangeira ou a distorção da percepção do valor das línguas e o aparecimento de atitudes linguísticas hierarquizantes que afetam a lealdade linguística dos falantes”.
