Like the other groups, the control group experienced a significant initial change in perceived shape when the glasses were first put on (Mcontrol = −0.023 ± 0.011, t(14) = −8.29, P < 0.001, d = −2.14). Unlike the intermittent-wear group, the control group did not experience significant shape adaptation (Mcontrol = 0.0027 ± 0.011, t(14) = 0.94, P = 0.361, d = 0.24), but there was no significant difference between the intermittent and control groups (t(28) = 0.99, P = 0.326, d = 0.37). The control group did experience a significant aftereffect (Mcontrol = 0.0065 ± 0.010, t(14) = 2.52, P = 0.025, d = 0.65), which was not significantly different from the intermittent group (t(28) = −0.25, P = 0.802, d = −0.094). To ensure the control group had a similar experience to the continuous- and intermittent-wear groups, the control group also performed the slant tasks. Across all other tasks performed by this group, we observed no significant adaptation effects, aftereffects, or cue reweighting.
