These revealed a significant linear trend in threat detection accuracy ( R 2 = 0.04, constant = 74, b = 0.74, p = 0.003; see also Table 2 ) and linear trends in HFA and d’ approaching significance (HFA: R 2 = 0.02, constant = 49, b = 0.81, p = 0.070; d’: R 2 = 0.02, constant = 1.37, b = 0.03, p = 0.058).
