We said above that the random effects are the group-level (the group unit is, in this model, the participants) version of the population-level effects (the fixed effects). One important thing to note is that they represent the **deviation from the fixed effect**, so a coefficient close to 0 means that the participants' effect is the same as the population-level effect. In other words, it's **"in the norm"** (note that we can also obtain the group-specific effect corresponding to the sum of the fixed and random by changing the `type` argument).
