HONEST LME (per-animal random slope, day|rat): interaction F(1,40.5)=2.61, p=0.1136

(Satterthwaite DF ~= residual on this random-intercept model; the random-slope
|
|
model above is the honest learning-rate test -- DF collapses toward the animal count.)

INTERPRETATION: stim x day interaction n.s. -- slopes parallel (no differential learning rate) (p=0.1013, slope diff=+0.01218)
