The Decisional Window

I bring this work as an Applied Performance Scientist, Certified Mental Performance Consultant (CMPC), and Certified Strength and Conditioning Specialist (CSCS), with over 30 years in high-performance settings. This background lets me bring mental skills, motor learning, and sport science into one integrated approach to how performers see, decide, and act.

Most errors in competition are not skill errors. They are timing errors. The athlete sees the play but decides after the window has already moved. Research shows that expert performers do not simply react faster. They pick up cues earlier, hold steadier visual focus before they act, and begin processing before the window fully opens. Research also shows that pressure narrows attention. Athletes stop reading the game and start reading themselves. Across a game, momentum can shift how an entire team reads, decides, and commits.

My work helps athletes, coaches, and teams understand and train this moment. That includes scanning and cue reading, decision making under realistic pressure, and Mind + Movement® training. That training pairs a physical skill with a thinking task, an approach known as Cognitive Motor Dual Task (CMDT) training. Practice is designed to look more like competition, with variation, consequences, and time pressure, because that is where the window becomes harder to enter. How well any training carries over to games is still an active research question, so I observe, measure, and adjust with every performer.
