HONEST LME (per-animal random slope, day|rat): interaction F(1,62.1)=3.56, p=0.06388

(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=0.06215, slope diff=+0.01317)
