Shape detection during training. a) Sensitivity measures (d′). b) Mean response times. Shape detection improved at all visual field locations (P_t, A, P_u) and both when sounds were presented at the same (valid) side (V) or the opposite (invalid) side (I). In addition, a location-specific change of the validity effect was observed on response times (see Fig. 5). Two consecutive training sessions were pooled. Error bars reflect within-subjects s.e.m. (Loftus & Masson, 1994) for the factor Training Session. n = 17
