failed to reach significancep = .075
Although the interaction between these two factors failed to reach significance, F (4, 120) = 2.184; p = .075, post-hoc pairwise comparisons showed that ITPCs for the Younger group differed from the Older group at the 13.5° and 18° angular shifts ( p = .029 and .03, respectively), but not for the 36° shift ( p = .759).
