- [00:00:02.652]My research encompasses a lot of different aspects
- [00:00:04.951]of human cognition, but there's a particular focus
- [00:00:07.284]on attention and eye movements,
- [00:00:09.017]so what sorts of things influence,
- [00:00:11.151]where attention moves,
- [00:00:12.219]how efficiently it moves,
- [00:00:14.171]and, in going with that, how the eyes move.
- [00:00:17.117]Attention is one of the most important aspects
- [00:00:19.186]of cognition, 'cause it's kind of the gateway
- [00:00:21.117]to perception and memory and all of these various forms
- [00:00:23.818]of processes, so eye tracking gives us an ability
- [00:00:26.719]to online track where people are looking,
- [00:00:29.217]where they're attending most of the time.
- [00:00:31.219]We have two eye trackers in the lab.
- [00:00:33.186]These are based on camera systems.
- [00:00:35.117]They grasp onto the pupil and then get a sense
- [00:00:37.484]of where the eye is moving moment to moment.
- [00:00:40.018]We also have an Oculus Rift in the lab,
- [00:00:42.018]which is a virtual reality helmet that allows us
- [00:00:44.251]to create environments to see how people interact
- [00:00:46.717]with those environments, and that doesn't have eye tracking
- [00:00:48.985]but it has head tracking.
- [00:00:50.351]We've integrated eye tracking into the FMRI and EEG systems.
- [00:00:55.151]We've used eye tracking with the physiological systems
- [00:00:58.585]in the political science lab, so it's really given us
- [00:01:00.850]the opportunity to kind of bring all of these
- [00:01:02.784]different areas of research together.
- [00:01:04.984]In CB3, we're talking about a live exciting collaborations,
- [00:01:08.518]not just with other academics and psychologists,
- [00:01:11.318]but also with athletics, so using eye movements
- [00:01:14.084]to gauge things like concussion.
- [00:01:15.835](crowd cheering)
- [00:01:17.541]The eye movement system, the ocular motor system,
- [00:01:19.685]is housed exclusively in the brain for the most part
- [00:01:22.418]so any sort of damage to the brain can lead to problems
- [00:01:25.184]with eye movements that you might not be able to see
- [00:01:27.250]in normal situations, so we're hoping to gain more insight
- [00:01:30.217]into that especially integrating this
- [00:01:32.084]into neuroscientific techniques as well.
