A recently introduced probabilistic methodology (Kamata, Tenenbaum, & Hanin, 2002) was implemented in the current study to ascertain the idiosyncratic Individual Affect-related Performance Zones (IAPZs) of four intercollegiate tennis players. The current study advances upon previous empirical works by its use of multiple performance levels, use of athletes’ introspective affective intensity, and recording multiple data points duringcompetition. Results present within- and between-player comparisons, and highlight the dynamic nature of competitive athletic events. A brief discussion regarding the implications of this methodology and the pursuant results for sport psychology consultants is also proffered. Being idiosyncratic in nature, the observations from this study are not intended to generalize across samples, but rather to introduce how knowledge of the systematic and dynamic linkage between an individual’s affect and his or her performance can be uncovered and possibly used with individual athletes to facilitate more consistently optimal performances.
