Why Convenience Could Be Shrinking Your Brain?
Psych 🧠- 427/500
Hello reader,
Ever wondered what happens to your brain when you let ChatGPT write your essay?
This research used EEGs to peek inside the brains of students as they tackled essay writing with and without AI assistance!
What is it?
The study analyzes brain activity of participants engaged in essay writing under different conditions: using an LLM (ChatGPT), using a search engine, and writing with no external assistance.
Researchers aimed to identify the cognitive costs + benefits associated with LLM use.
Key Findings:
Using LLMs decreased overall brain connectivity and shifted the focus away from internal generation to external resources.
Writing without Al assistance (Brain-only group) led to stronger neural networks associated with memory, planning, and high-level attention.
While AI can streamline the writing process, it may lead to reduced cognitive engagement and internal development of ideas.

What do I need to know:
AI writing tools can change how our brains engage with learning.
While LLMs improve efficiency, they may reduce deeper cognitive processing and creative thinking.
A balanced approach that combines Al assistance with independent learning is ideal for optimizing both performance and skill development.
