MIT Experiment Finds ChatGPT-Assisted Writing Weakens Student Brain Connectivity and Memory

1 month 3 weeks ago
ChatGPT-assisted writing dampened brain activity and recall in a controlled MIT study [PDF] of 54 college volunteers divided into AI-only, search-engine, and no-tool groups. Electroencephalography recorded during three essay-writing sessions found the AI group consistently showed the weakest neural connectivity across all measured frequency bands; the tool-free group showed the strongest, with search users in between. In the first session 83% of ChatGPT users could not quote any line they had just written and none produced a correct quote. Only nine of the 18 claimed full authorship of their work, compared with 16 of 18 in the brain-only cohort. Neural coupling in the AI group declined further over repeated use. When these participants were later asked to write without assistance, frontal-parietal networks remained subdued and 78% again failed to recall a single sentence accurately. The pattern reversed for students who first wrote unaided: introducing ChatGPT in a crossover session produced the highest connectivity sums in alpha, theta, beta and delta bands, indicating intense integration of AI suggestions with prior knowledge. The MIT authors warn that habitual reliance on large language models "accumulates cognitive debt," trading immediate fluency for weaker memory, reduced self-monitoring, and narrowed neural engagement.

New US Visa Rules Will Force Foreign Students To Unlock Social Media Profiles

1 month 3 weeks ago
An anonymous reader quotes a report from The Guardian: Foreign students will be required to unlock their social media profiles to allow US diplomats to review their online activity before receiving educational and exchange visas, the state department has announced. Those who fail to do so will be suspected of hiding that activity from US officials. The new guidance, unveiled by the state department on Wednesday, directs US diplomats to conduct an online presence review to look for "any indications of hostility toward the citizens, culture, government, institutions, or founding principles of the United States." A cable separately obtained by Politico also instructs diplomats to flag any "advocacy for, aid or support for foreign terrorists and other threats to US national security" and "support for unlawful antisemitic harassment or violence." The screening for "antisemitic" activity matches similar guidance given at US Citizenship and Immigration Services under the Department of Homeland Security and has been criticized as an effort to crack down on opposition to the conduct of Israel's war in Gaza. The new state department checks are directed at students and other applicants for visas in the F, M and J categories, which refer to academic and vocational education, as well as cultural exchanges. "It is an expectation from American citizens that their government will make every effort to make our country safer, and that is exactly what the Trump administration is doing every single day," said a senior state department official, adding that Marco Rubio was "helping to make America and its universities safer while bringing the state Department into the 21st century."
