Description of the behavioral measures used in the human and rodent 5C-CPTs.

Measure Description
Hit Response to target stimulus in correct location
Miss Non-response to target stimulus
Incorrect Response to target stimulus but in wrong location
Correct Rejection (CR) Correct non-response to non-target stimulus
False alarm (FA) Incorrect response to non-target stimulus
Premature response Response to no stimuli during the inter-trial interval
Mean reaction time (RT) Mean latencies to correct responses
Variable RT Standard deviation of the RT
Hit rate (HR) Proportion of correct responses to target stimuli
False alarm rate (FAR) Proportion of incorrect responses to non-target stimuli
Vigilance (d) Parametric measure examining the difference between Hit and False alarm rates to determine performance
Responsivity index (RI) Non-parametric measure examining the combination of Hit and False alarm rates to determine responsivity to stimuli
Accuracy Proportion of correct compared to incorrect responses
% Omissions Percentage of misses/lapses
