Detection Error Rate The analysis of the detection error rate indicated main effects of expertise ( F (1, 51)=35.19, p <.001, η 2 =.41), presentation ( F( 1, 51)=59.89, p <.001, η 2 =.54) and modification (marginally significant; F (1, 51)=3.51, p =.067, η 2 =.06), with a lower error rate for experts (21%) compared to non-experts (46%), in simultaneous presentation (21%) compared to sequential presentation (47%) and in violation (31%) compared to no violation (36%).
