What happens in the brain after watching short and long content? The experiment tracks changes in brain activity before and after screen time, using EEG measurements, neurofeedback software and attention tasks.

Short video formats have taken over everyday life, but what do they do to attention? In this experiment, changes in brain activity were tracked before and after exposure to the screen.

The team used EEG measurements, neurofeedback software and attention tasks, comparing the effects of short and longer content.

The video follows:

• the state of the brain before watching content
• changes after short content
• changes after longer content
• what happens to attention and the need for stimulation

The authors stress that the results are not proof of a final truth, nor a diagnosis, but an experiment that opens a question for further research: does fast content merely entertain us, or does it change the way the brain seeks stimulation.
