Table 2 Median (interquartile range) scores by group on the Tactile Defensiveness and Discrimination Test-Revised (TDDT-R)

From: Intrainsular connectivity and somatosensory responsiveness in young children with ASD

Tactile ability/response TDDT-R ASD TD p value
Discrimination Form perception 12.17 (3.92) 9.71 (4.22) 0.0125
Affective response Defensiveness to externally (experimenter) controlled touch 0.1875(.03) 0.0625 (.13) 0.0257
Defensiveness to touching objects or materials 0.2143 (.25) 0.1429 (.14) 0.0339
Tactile seeking 0.2857 (.14) 0.0000 (.14) .0003
  1. Externally controlled touch is the touch administered by the examiner; internally controlled touch is tactile exploration of objects or materials by the participant. For form perception, higher scores indicate poorer performance (i.e., more time manipulating objects needed to accurately discriminate form). For all other tests, higher scores indicate more observable affective responses to sensory probes. p values represent Mann–Whitney U tests. Significant p values are in italics
