...3 dfs for each main effect of stimulusName, responseFinger, oom, and mapping.code. That leaves 3 df to estimate any higher-order interactions involving these 4 factors. To capture this variance I use stimulusName:mapping.code, but I believe I could use any of the two-way interactions. The variance aassociated with this effect should be orthogonal to the variance for the main effects. However, when I look at the contrasts with summary.lm it seems as though the estimates of contrasts involving responseFinger, for example, depend on whether stimulusName:mapping.code is in the model. That suggests to me tha...
