The current study investigated the relationship between the contextual interference effect and knowledge of results manipulations. Specifically, three variations of a relative timing task were presented in either a blocked or random schedule, and participants were either required to error estimate or given no instruction concerning estimation. A 2 (Acquisition Context) x 2 (Error Estimation Frequency) ANOVA was used to analyze absolute error (AE), variable error (VE) and a relative timing measure (AE(prop.)). The main effects that there was a blocked advantage during retention. In addition, a 100% estimation advantage existed for AE and VE, but was not present for AE(prop.). These results indicate that the relative difficulty of the task may have been too high to produce a random group advantage and that error estimation of relative timing may have been too much for the participant to process. In conclusion, it was proposed that the two factors may interact, but relative difficulty of the task needs to be taken into account.
