Table I.

Statistical tests on the difference between parameter estimates. The Prob column reports the probability that each hypothesis holds according to a Wald test of linear restriction using robust standard errors. The Sign column shows a + or - if the test is significant in that direction at the 5% level, with a *appended if significant at the 10% level. Regressions run on 74088 data points (TRs) from 2975 trials, 189 scans and 12 subjects.
