Technical and focus threshold testing is a low-tech method that is used to help determine the extent to which an athlete exhibits technical/motor control and concomitant focus or attention in the context of sport-specific task challenges of increasing level of difficulty. It is an important first step in on-the-playing-field assessment of technical/physical and psychological performance, allowing a coach and sport psychology practitioner to quantify technical-psychological balance or how much of an athlete’s performance equation can be explained on the basis of mind-body factors. It provides criterion-referencing for in-office self-report and psychological test scores as well as practitioner intuition. A major issue in the technical-focus threshold equation involves temporal dynamics or time that it takes to achieve enduring change (TAC). TAC can be operationalized as the amount of time that it takes to achieve neuronal consolidation of a technical skill, context-specific attention span, or any other performance-relevant psychological tendency or behavior.
