Abstract:
Based on potential performance theory (PPT), a methodological paradigm is developed that allows for individual-level analyses. The proposed methodology distinguishes among observed performance, strategy, and consistency, with the idea that changes in observed performance can be caused by changes in strategy or consistency. Equations are presented that allow the computation of strategy and consistency scores for groups and individuals, with the goal of enabling researchers to find the reasons why performance improves or does not improve. More specifically, people may (1) develop better strategies, (2) use them more consistently, (3) both, or (4) neither. It is even possible to have strategy-consistency trade-offs, as individuals focus on one at the expense of the other. Data obtained from an experiment illustrate these possibilities.

First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...
