Eye-tracking allows studying aspects that cannot be seen, i.e., the thinking processes of solving a math problem. In a new systematic review of the research, findings show researchers are integrating eye-tracking into education and are using the technology to radically improve the teaching of maths

Researchers have measured subjects' memory by tracking their eye movements 👀 as they watched animation videos 🎥, demonstrating that people actually remember more than they report. This method can be used to measure memory in subjects who cannot speak 🗣️.

Scientists Find a Subtle Clue to ADHD Hidden in The Eyes. Study suggests tiny changes in the pupils, as the brain tries to remember something, ignore a distraction, or make a decision, may be subtly different in unmedicated children with ADHD. Medicated children were more like the control group.

👁️ Scientists suspect pupil changes, beyond light adjustment, might reveal attention patterns in children. A new study reanalyzed eye-tracking data from 50 children (ages 10-12) playing a memory game.

🧠 Researchers found approximately 23% greater trial-to-trial variability in pupil responses among unmedicated children with ADHD compared to those without a neurodevelopmental diagnosis. This suggests pupils may subtly reflect shifts in attention.

💊 When medicated with methylphenidate, the pupils of children with ADHD responded more strongly and fluctuated less, appearing more similar to the control group. However, researchers caution this doesn't definitively prove medication "normalizes" attention, as the drug can directly affect pupil size.

🔬 While intriguing, it's too early to use pupil measurements as a clinical diagnostic tool for ADHD. Larger, independent studies are needed to confirm reliability in real-world settings. Eye-tracking could potentially complement existing diagnostic methods in the future.

New eye-tracking study finds men spend longer looking at attractive faces only if they're the sex they're attracted to, but women look longer at attractive faces of both men and women. And being in a long-term relationship didn't stop people from lingering on good-looking faces either.

👩‍❤️‍👨 Men tend to look longer at attractive faces that match their sexual orientation, while women look longer at attractive faces regardless of sex. This preference emerges during deliberate viewing, not initial automatic attention.

👀 Eye-tracking shows that immediate, automatic attention to faces isn't strongly influenced by attractiveness. Instead, screen position (favoring the left side) plays a larger role in initial glances.

⏱️ Deliberate, sustained viewing reveals distinct patterns: women show a general bias towards attractive faces of any sex, while men are more selective, focusing on attractive faces aligning with their sexual preference.

❤️ Relationship status did not significantly impact how long people looked at attractive faces, contrary to some prior expectations, possibly due to the long duration of relationships in the study sample.
