7 – What Should an Athlete Pay Attention To?
What should an athlete focus their attention on when performing their sport? Should you pay attention to how your body is moving, the crowd, your opponents, what you need to buy at the store after the game, or something else? Is it the same if you just learning the sport? In this episode I focus my attention of focusing attention.

6 – Embodied Perception in Sport
Why do great athletes claim that on some nights baseballs look as big as a grapefruit, basketball hoops are like oceans and things move in slow motion? Are they just blowing a lot of hot air or is this really the way they see the world? In this episode, I explore embodied perception in sport…the idea that the way we see the world changes as a function of our action capabilities (e.g., whether we are an expert or novice, whether we are fresh or fatigued, etc). I also consider how we might take advantage of these effects in sports training programs.

5 –Vision in Hitting and Catching
How does an athlete get their glove, racquet, hand, or foot to the right place at the right time to hit, catch or strike a moving object? In this episode, I explore visual information that can be used to judge the time to contact and direction of motion of an approaching object and how it can be applied to the outfielder problem.

4 – Anticipation in Sports
How do great athletes seem to know what is going to happen next? What information to they use to predict the next serve will be cross court instead of down the line, how does a baseball batter know the next pitch will be a fastball, and how does an NFL quarterback know the defense will blitz? Can these abilities be improved through training? In this episode I explore the topic of anticipation in sports.

3 – Eye Movements in Sports
What should an athlete look at when performing their sport? For example, should a soccer goalkeeper keep their eye on the shooter’s leg when trying to stop a penalty kick or on their upper body? Should a golfer look at the ball or the hole when putting? Do expert athletes look at different things than novices? Is it really possible to always keep your eye on the ball? In this episode, I examine the role of eye movements in sports.

2 - Vision Training Programs
Since the early 1980's, there have been several vision training programs developed which propose to improve the vision of athletes resulting in an associated improvement in their sports performance. Do these training programs actually work? Or could practice time be put to better use? In this episode, I review the research that has evaluated the effectiveness of these programs.

1 - Vision in Sports
Sports talk is littered with phrases related to our eyes. We talk of great court vision, a good eye at the plate and seeing the ball well. But just how critical is vision to an athlete?Do professional athletes see better than we do? Can you play sports effectively if you have poorer than 20/20 vision? In this episode I dive into the topic of research in vision in sports.
