Table 2. Demographics of the fMRI groups.
On average, the head displacement of congenitally blind individuals (E−A) was 1.564 ± 0.985 mm, while the head motion of typically developed individuals exposed to the same stimulus modality (E+A) was 0.864 ± 0.681 mm [t-stat(17.81) = 1.909; P value = 0.073]. For what concerns fMRI data collected during the visual experiment, head motion measured in congenitally deaf individuals (E−V) was, on average, 0.715 ± 0.401 mm, whereas in typically developed individuals (E+V) was 0.709 ± 0.471 mm [t-stat(16.96) = 0.030; P value = 0.977]. In addition, no significant differences were found when we compared head motion values of people with sensory deprivation to those of typically developed individuals presented with the multisensory stimulus [E+M head motion: 0.889 ± 0.742 mm; E−A versus E+M: t-stat(18.41) = 1.784; P value = 0.091; E−V versus E+M: t-stat(14.11) = −0.645; P value = 0.529].
