Figure 3. Confidence intervals of the deviations of the intercepts from the population mean for the levels of the random effect (combination of face, gesture and context).

Especially for the negative context, we found large CI’s reflecting the rare data points within this context. SG, stretched arm gesture; BG, bent arm gesture; bared, bared teeth display; funnel, funneled lip face; neu, neutral face; pos, positive context; neg, negative context. BG_hoot_neg did not occur.
