Which words from the excerpt would be most useful while writing a summary of this paragraph?

Jessica Witt – a professor at Colorado State University – has spent her whole career studying the relationship between what the mind sees (perception) and action by the body. She doesn't think the mind is like a camera, seeing exactly what is actually there. "We don't think that perception is just this objective recapture of what's already out there," says Witt. Instead, the mind sees things based on how the person feels at that moment. She has been testing this by asking athletes their impressions of key activities in their sports.
