Title: External location of touch is constructed post-hoc based on limb choice Document date: 2019_2_14
ID: euu5atwo_6
Snippet: Several explanations have been put forward to account for crossing effects 79 in tactile localization. First, it has been suggested that touch location, once it is 80 remapped, is retained only in an external spatial code, and the original skin location 81 is discarded in the process. To report which body part has been touched, the brain 82 must then reversely determine which limb was located at the computed external 83 location at the time of th.....
Document: Several explanations have been put forward to account for crossing effects 79 in tactile localization. First, it has been suggested that touch location, once it is 80 remapped, is retained only in an external spatial code, and the original skin location 81 is discarded in the process. To report which body part has been touched, the brain 82 must then reversely determine which limb was located at the computed external 83 location at the time of the touch (Kitazawa, 2002; Kitazawa et al., 2008; Yamamoto 84 & Kitazawa, 2001) . We refer to this suggestion as the space-to-limb reconstruction 85 hypothesis. When applied to errors in the TOJ task, this hypothesis implies that 86 participants correctly remap the two tactile stimuli into external space, but then 87 reconstruct erroneously which hand was at the first spatial location. 88
