Highly significant effects of days ( E : F 2, 56 = 49.4, p < 10 −6 ; MaxT: F 2, 56 = 6.26, p < 0.005; pTime: F 2, 56 = 47.1, p < 10 −6 ; ED: F 2, 56 = 52. 6, p < 10 −6 ) showed robust learning in all rats during training.

Marginally insignificant treatment × session interactions ( E : F 4, 52 = 2.32, p < 0.069; D : F 4, 52 = 2.54, p < 0.051) reflected a trend toward hyperlocomotion and poorer avoidance after the higher dose of MK-801 specifically in session 1.
The t -test analysis fell short of significance, but this shortcoming was partly due to too much impairment rather than too little and partly due to a single animal, which displayed neither deteriorated avoidance nor increased locomotion after switching to 0.15 mg/kg MK-801 and resembled behavioral pattern observed in controls.
