Need advises on mixed-effect model ( a concrete example)
...I tend to prefer the first approach for some reason but I need confirmation the correctness of both approach. My questions : 1) are both possibility correctly implemented in my analysis ? 2) Is one way better than the other ? 3) Is there better ways of testing the effects of group, condition and acoustQ ? 4) If one of my factor's effect is significant, how can I test correctly the difference between the modalities of this factor (since it seems that the t-values in the model summary are not a good way of doing this). Is there a specific post-hoc procedure ? Thanks in advance for any help...
