An alternative model of reflection-impulsivity is presented, consisting of a style dimension and an efficiency dimension, along with a methodological alternative to the traditional dependence on raw error and latency scores for classification. The use of impulsivity and efficiency scores is suggested as a procedure which integrates components of speed and accuracy, generating continuous, numerical indices of style and strategy, and does so for all subjects tested, not just those in the impulsive and reflective quadrants of the latency x errors scatterplot. In principle the model applies to tasks such as MFF performance, where speed and accuracy are negatively correlated and where impulsivity is the major axis and efficiency is the minor axis. Implications for understanding children’s cognitive strategies and styles across various tasks are discussed.
