ChatGPT May Be Eroding Critical Thinking Skills, According to a New MIT Study
By Andrew R. Chow
The study divided 54 subjects — 18 to 39 year-olds from the Boston area — into three groups, and asked them to
write several SAT essays using OpenAl's ChatGPT, Google’s search engine, and nothing at all, respectively. Researchers used an (electroencephalogram) EEG to record the writers’ brain activity across 32 regions, and found that of the
three groups, ChatGPT users had the lowest brain engagement and “consistently underperformed at neural, linguistic,
and behavioral levels.” Over the course of several months, ChatGPT users got lazier with each subsequent essay, often
resorting to copy-and-paste by the end of the study.
The paper suggests that the usage of (Large Language Model) LLMs could actually harm learning, especially for
younger users. The paper has not yet been peer reviewed, and its sample size is relatively small. But its paper’s main
author Nataliya Kosmyna felt it was important to release the findings to elevate concerns that as society increasingly
relies upon LLMs for immediate convenience, long-term brain development may be sacrificed in the process.
The group that wrote essays using ChatGPT all delivered extremely similar essays that lacked original thought,
relying on the same expressions and ideas. Two English teachers who assessed the essays called them largely
“soulless” The EEGs revealed low executive control and attentional engagement. And by their third essay, many of
the writers simply gave the prompt to ChatGPT and had it do almost all of the work. “It was more like, ‘just give me the
essay, refine this sentence, edit it, and 'm done,” Kosmyna says.
The brain-only group, conversely, showed the highest neural connectivity, especially in alpha, theta and delta bands,
which are associated with creativity ideation, memory load, and semantic processing. Researchers found this group
was more engaged and curious, and claimed ownership and expressed higher satisfaction with their essays.
The third group, which used Google Search, also expressed high satisfaction and active brain function. The
difference here is notable because many people now search for information within Al chatbots as opposed to Google
Search.
After writing the three essays, the subjects were then asked to re-write one of their previous efforts—but the
ChatGPT group had to do so without the tool, while the brain-only group could now use ChatGPT. The first group
remembered little of their own essays, and showed weaker alpha and theta brain waves, which likely reflected a
bypassing of deep memory processes.
The second group, in contrast, performed well, exhibiting a significant increase in brain connectivity across all EEG
frequency bands. This gives rise to the hope that Al, if used properly, could enhance learning as opposed to diminishing it.

CONTEXTUALIZAÇÃO
Há 80 anos, em 8 de maio de 1945, a Europa calava seus canhões. Para o Brasil, essa data vai além da memoria global: ela eterniza a Força Expedicionária Brasileira (FEB) como um dos mais nobres símbolos de coragem e amor a pátria — um legado que inspira gerações e honra a historia do nosso paıs. O Dia da Vitoria, celebrado mundialmente em 8 de maio, representa a rendição incondicional das forcas do Eixo aos Aliados e o fim oficial da Segunda Guerra Mundial na Europa. No Brasil, e também o momento de honrar os 25 mil combatentes da FEB, que levaram o nome da pátria aos campos de batalha italianos e regressaram como heróis da liberdade.

remota para confundir e desativar o armamento inimigo.” (texto 2, linhas 6 a 8)
No excerto retirado do texto 2, observa-se uma progressão coesiva entre duas frases, mesmo sem o uso de conectivo. Considerando a relagdo semantica entre essas frases, assinale a alternativa que apresenta uma locução ou conjunção que poderia ser empregada pelo autor, mantendo o mesmo sentido do fragmento.

CONTEXTUALIZAÇÃO
Há 80 anos, em 8 de maio de 1945, a Europa calava seus canhões. Para o Brasil, essa data vai além da memoria global: ela eterniza a Força Expedicionária Brasileira (FEB) como um dos mais nobres símbolos de coragem e amor a pátria — um legado que inspira gerações e honra a historia do nosso paıs. O Dia da Vitoria, celebrado mundialmente em 8 de maio, representa a rendição incondicional das forcas do Eixo aos Aliados e o fim oficial da Segunda Guerra Mundial na Europa. No Brasil, e também o momento de honrar os 25 mil combatentes da FEB, que levaram o nome da pátria aos campos de batalha italianos e regressaram como heróis da liberdade.

Q1321096
Química
É requerido que fazendas produtoras de leite bovino controlem a acidez do leite que está aguardando o processamento. Essa acidez é resultante da conversão da lactose em ácido lático (ácido 2-hidroxipropanoico) por ação de microrganismos:
C12H22O11 + H2O → 4C3H6O3
Um fazendeiro decidiu fazer um experimento para determinar a taxa de geração de ácido lático no leite armazenado: retirou uma amostra de 50 cm3 de leite, cuja concentração de ácido lático é de 1,8 g/L, e, depois de três horas, utilizou 40 cm3 de uma solução 0,1 molar de NaOH para neutralizá-la.
Conclui-se que a taxa média de produção de ácido lático por litro de leite é:

Admita que uma solução aquosa 0,0400 molar de ácido tricloroacético congele a −0,1395 ºC. Considere,
ainda, que a constante de abaixamento do ponto de congelamento (Kc) da água seja 1,860 ºC.kg.mol−1 e que
1,00 L de solução contenha 1,00 kg de solvente. O valor da constante de dissociação (Ka) do ácido
tricloroacético será:
Q1321092
Física
Um tubo sonoro de comprimento total L = 1m, aberto nas duas extremidades, possui uma parede móvel em seu interior, conforme a figura. Essa parede é composta de material refletor de ondas sonoras e pode ser transladada para diferentes posições, dividindo o tubo em duas câmaras de comprimento L1 e L2. Duas ondas sonoras distintas adentram nesse tubo, uma pela abertura da esquerda, com f1 = 2,89 kHz, e outra pela abertura da direita, com f2 = 850 Hz. Em relação às ondas sonoras, os valores de L1 e L2, em cm, que possibilitarão a formação de ondas ressonantes em ambas as cavidades são, respectivamente:

• O meio no interior do tudo é o ar, onde o som se propaga com velocidade 340 m/s.
