In contrast, the error rate in the hard condition at SOA 900 ( m = 15%) was not significantly different from that at SOA 50 ( m = 12%), t (23) = -1.7, p > .09, and SOA 300 ( m = 12%), t (23) = 0.824, p > .40, while the difference approached significance compared to that at SOA 150, ( m = 11%), t (23) = 2.02, p = .054.
