# Stopper Lab > Stopper Lab is a visual attention, human behavior and AI research lab. It combines behavioral simulation, predictive AI, eye tracking, EEG and GSR/EDA measurement to understand, measure and predict the stopping power of images and videos. Stopper Lab is an Attention Intelligence ecosystem with four connected parts: Stopper Theory (scientific foundation: why do we stop?), Stopper Lab (human research and validation with eye tracking, EEG and GSR/EDA), Stopper AI (predictive analysis of images: nine analyses and a 0–100 Stopper Score) and Stopper Analyze (behavioral feed simulations with real participants). The site is available in English and Turkish. Contact: hello@stopperlab.com.

It asks what interrupts the flow of human attention and makes a person stop on a visual. We call that effect Stopping Power. - [Ecosystem](https://stopperlab.com/ecosystem): Stopper is not a single AI application or a single laboratory. It is a research and technology ecosystem built to understand, measure, analyze and, over time, predict visual attention. - [Lab](https://stopperlab.com/lab): Stopper Lab measures how visual and video content affects human attention and behavior, using behavioral analysis, artificial intelligence, eye tracking, EEG and GSR/EDA data together. It is structured within… - [Sectors](https://stopperlab.com/sectors): Social media is where Stopper began. But the idea is wider: static visuals, moving images, video, digital interfaces and, with the right research design, physical environments, from mobile screens to store shelves. - [Research & Insights](https://stopperlab.com/research): Explore Stopper research, reports, presentations, videos, podcasts and perspectives on visual attention, human behavior and Attention Intelligence. - [About](https://stopperlab.com/about): Every day we meet thousands of visual stimuli. We pass most, see some, and give our full attention to a few. Stopper was born from the idea that these moments are not accidental and can be measured. - [Contact](https://stopperlab.com/contact): Tell us about the content you want to test: a campaign, a package, an interface, a game, a video or a space. We will propose a research design built to need, from a single AI analysis to the full Stopper Lab study. ## Ecosystem stages - [Stopper Theory](https://stopperlab.com/theory): The Idea.
