Traditional ways to examine and investigate the neural correlates of consciousness usually require the participants to actively report their perceptions and conscious contents. Having the participants actively report can confound the neural correlates with co-occurring processes. Instead, no-report paradigms try to remove the active process of reporting by either objectively trying to measure conscious content by tracking eye movements and pupil dilation, or retroactively inquire about the conscious states. The results of an fMRI experiment utilising tracking of optokinetic nystagmus and pupil dilation as an objective measure of conscious content highlight a difference in frontal areas while activation in posterior areas are similar to active report experiments. EEG experiments utilising the sustained inattentional blindness paradigm did not see the late positivity commonly seen when the participants were aware of the stimuli but it was not task relevant. Utilising no-report paradigms can provide unique insights into the discussion of theories of consciousness and further develop our understanding of consciousness.
