In experimental research, large numbers of participants are used to average out individual differences in the data. However,differences in task performance may be largely due to two factors; lack of task training, and different micro-strategies. Weimplement a methodology that removes the effect of these factors, requires only 23 participants, and still produces largeamounts of data. Other studies have been published using a similar methodology (Cousineau & Shiffrin, 2004; Gray &Boehm-Davis, 2000). Our study is a revision of previous research using a mobile game (West et al., 2018). Participants aretrained extensively on the game to ensure they are experts. The study includes a predictive cognitive model and the game-design is based on an apparent micro-strategy. We hypothesize that the same micro-strategies under identical conditions,should produce identical results across participants and the model. Suggesting the model may exist in the mind of humanexperts.
