HONEST LME (per-animal random slope, day|rat): interaction F(1,7.0)=9.42, p=0.0181
  (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 SIGNIFICANT positive -- treatment improves FASTER (benefit accumulates) (p=0.0006736, slope diff=+0.04981)
Paper (N=24, count): interaction t(227)=2.68, F(1)=7.12, p=0.008.
