Note. Columns A to C contain GEE analyses, (A) for all six fingers and three sessions, which indicates fingers change differently over finger and session; (B) analyses with the deafferentation-adjacent finger removed reveals the remaining fingers change in the same way over sessions (i.e., collapsing values over these fingers is appropriate; ‘R’ denotes ‘right’ in the heading); and (C) hypothesis-driven follow-up tests. This reveals significant differences between the trained finger vs. five remaining fingers (av. remaining 5) in the offline session. This corresponds to a main effect of Finger (Ci), reducing to a trend by the long-term retention sessions (Cii; see in-text for direction of this finger main effect and its interpretation). Follow-up GEEs in Column C were Bonferroni corrected for multiple comparisons (α = .25). QICC = corrected quasi-likelihood under independence model criterion. Shaded sections indicate critical interactions. | ||||
a Indicates this comparison was rerun without data for the injected finger while anaesthetic effects may have still been apparent (right index finger, online session); interaction remained significant at p < .05. | ||||
