Fig 2. Accuracy in the tactile congruency task for factors Group, Instruction, Hand Posture, and Congruency (coded anatomically).

Data are collapsed over static and dynamic movement conditions, as this manipulation did not render any significant results (see main text for details). Sighted (1^st and 2^nd column) and congenitally blind participants (3^rd and 4^th column) were instructed to localize tactile targets either relative to their anatomical (1^st and 3^rd column) or relative to their external spatial location (2^nd and 4^th column). Hands were placed in the same (black circles) and in different orientations (grey triangles). Tactile distractors were presented to anatomically congruent (C) and incongruent (IC) locations of the other hand and had to be ignored. Congruency is defined in anatomical terms (see Fig 1). Accordingly, with differently oriented hands, anatomically congruent stimulus pairs are incongruent in external space and vice versa. Whiskers represent the standard error of the mean. Note, that we present percentage-correct values to allow a comparison to previous studies (see methods for details), whereas for statistical analysis a log-linked GLMM was applied to single trials accuracy values.
