Most athletes think focus is something they either have or lose, but attention works differently. During competition, the brain continually decides what deserves priority, and under pressure, that spotlight can shift from the ball and target toward score, consequences, mechanics, mistakes, and fear. In Lab 4 of The Mental Fitness Lab™, we explore the neuroscience of selective attention, why pressure changes what athletes notice, and why the most important attentional skill may not be maintaining perfect concentration but learning how to return when the mind wanders. Through simple tools such as **NOTICE → RELEASE → RETURN** and **BALL → BREATH → TARGET**, players can begin training attention as intentionally as they train strokes, movement, and conditioning.
