For Better or Worse: The Effect of Prismatic Adaptation on Auditory Neglect

Table 3

Performance in auditory localization before (pre-R-PA) and after (post-R-PA) exposure to R-PA. Scores outside the normal range are in bold. The global score corresponds to the number of stimuli correctly placed to the left or the right of the previous stimulus. The perceived positions of each of the five stimulus locations are indicated in degrees (positive in the right, negative in the left space). The ability to discriminate between the two positions within either hemispace (LL versus L; R versus RR) was assessed by t-tests; positions which failed to be discriminated are highlighted in bold. In the control population, 10% of subjects failed to discriminate the two positions within one hemispace, never within both hemispaces. The number of alloacusis is indicated separately for those where stimuli presented on the left were indicated on the right (L to R) and those where stimuli presented on the right were indicated on the left (R to L). Control subjects never presented alloacusis.
