The same-different task requires to subjects to indicate whether a pair of stimuli seen or heard are the same (say AA or BB) or different (say AB or BA). Researchers often collect offline measures (e.g. response accuracy and latency) in the task.

Is there a way that I can collect online measures using eye-tracking, ERP or some other experimental techniques in psychology? In other words, instead of people reporting whether the pair of stimuli are different, I hope to infer their knowledge based on their fixations and brain potentials. Please recommend papers that I can read (if any). Thank you!
