Fast and slow strategies in multiplication

Parameters describing person characteristics (ability) and item characteristics (easiness) are estimated with the model. Both item and person characteristics differed between fast and slow processes and match predictions from substantive models of multiplication. Moreover, the parameters allowed us to describe the fast and slow strategies in more detail. Results emphasize the utility of the fast-slow model in the detection of strategies in multiplication but also in other areas of cognition and learning where strategies are expected.
