Effects of SC inactivation on target selection performance across 11 lidocaine injection sites. Each panel shows performance for one of the four target locations, pre-injection, during SC inactivation, and after recovery from inactivation. The relative positions of the four target locations are shown in E: the “inject” location (A) was near the estimated center of the inactivated field (dashed circle); “ipsi” (B) was 90° in direction from inject in the same hemifield; “contra” (C) was 90° away in the opposite hemifield; and “opposite” (D) was 180° in direction from inject. Pre-injection and after recovery, performance improved when a greater number of homogenous distractors was present in the display, for all four target locations (A-D). During SC inactivation, performance at the inject location declined with more distractors (A), while performance at the other locations was similar to pre-injection performance (B-D). Error bars show +/− standard deviation across sites.
