An integrative model of cognitive skill learning is presented that unites the log-log linear, instance, and cognitive-psychometric perspectives in a single comprehensive account. The conceptual model was evaluated in a task context requiring the computation of outputs for digital logic gates and analyzed via latent growth curve statistical models. The model testing process also used confirmatory factor analyses to evaluate the structure of working memory and latent growth curve models to evaluate the suitability of repetition priming as an indicator of procedural memory. Regarding working memory it was found that the structure best describing working memory is a two-factor solution representing the verbal and visuospatial domains. However, the dominant aspect of working memory involved in skill learning is a single general capacity component. Initial analyses of repetition priming showed that it is a multiepisodic phenomenon that takes the form of a power function. When entered into a latent growth curve model of cognitive skill learning, repetition priming showed an increasing relationship with the later stages of skill acquisition and working memory showed a decreasing relationship. Together, these results regarding the form and function of repetition priming support the hypothesis of an isomorphism between repetition priming and procedural memory. Regarding part/whole-training, it was found that computing single logic gates (part-training) versus computing three-gate circuits (whole training), produced equivalent levels of performance in a criterion task that involved computing three-gate circuits. However individual differences analyses showed that single-gate training led to performance that is more efficient in terms of working memory capacity. It seem that part training engenders more efficient strategies or algorithms that are compiled as procedural memories and become the basis of increased autonomy. Overall, it is hoped that this study, which integrated experimental and differential research methodologies with complex statistical models of change, will serve as an example of a new and potentially powerful research technique.
