Table 1.
Group mean reaction times (RT) and hit rates for each stimulus modality in each condition for experiment 1 and experiment 2. D-prime and bias for the visual modality in each condition for experiment 2. Please note that d-prime and bias could be computed neither for experiment 1 (because there were no non-targets included in the paradigm) nor for auditory modality of experiment 2 (because participants did not make any false alarms in the +att −exp condition).
