This potential indication of reduced task motivation was investigated using additional measures: for mean post-reinforcement latency (s) there was a borderline non-significant AS × genotype interaction [ F (1, 37) = 3.3, p < 0.08]: HET-AS mice (6.1 ± 0.8) had a longer post-reinforcement latency than HET-No-AS mice [4.0 ± 0.4; t (19) = 2.4, p < 0.03].
