We welcome the contribution of Puts and colleagues (2014) and commend their use of rigorous psycho-physical tasks in the investigation of sensory discrimination in autism. Here, our intention is to highlight previously published work that stands counter to the findings of Puts et al. in an attempt to ensure that the work is considered in a balanced context. Puts et al. find clear evidence for reduced tactile discrimination in autism, yet there are numerous examples of enhanced discrimination in autism. Enhanced discrimination has been reported in the visual domain (Bertone et al. 2005) and in the auditory domain (Bonnel et al. 2003), and also, in direct contrast to the findings from Puts et al., in the tactile domain (Blakemore et al. 2006).
