Research examining planning strategies used by high-strategy open-skill performers is limited. This study examined planning responses of collegiate varsity (experts, n = 6) and beginner (novices, n = 6) women tennis players between points during competition. Other articles focused on expert-novice differences in problem representations (quantitative analyses of verbal data via audiotaping) accessed during simulated situations and during actual competition (immediate recall point interviews) and performance skills during competition (via videotaping). Mann-Whitney U tests on verbal report measures indicated experts generated more total, varied, and sophisticated goal, condition, action, and do concepts than novices. Experts planned for actions based on elaborate and sophisticated action plan and current event profiles; novices rarely planned and they lacked these memory structures. Differences in internal self-talk were also noted.
