(A) The table shows the average agreement of the 20 repetitions across all 8 fMRI subjects. CEREBRA Approaches 1 and 2 agree with human responses 77%, CEREBRA Approach 3 agrees 75%, when the chance level is 68%. (B) The table shows the means and variances of the CEREBRA change models and the chance model for each subject, and the p-values of the Student t-test, revealing that the differences are highly significant. Comparison agreement with human judgements where all four subjects agreed.
