Having a high sensory sensitivity does not always mean that a person has a sensory processing disorder (SPD). Sensory-processing sensitivity (SPS ; scientific term for highly sensitive person) has characteristics similar to SPD, also known as sensory integration dysfunction. However, SPD is a disorder often associated with autism profile and demands professional intervention. In Japan, only a few academic have been studied on SPS or highly sensitive person have been examined comparing to the numbers of psychological studies and interventions conducted concerning SPD. To investigate the difference between SPS and SPD, a survey was administered to Japanese college students' participants with two questionnaires, Japanese version of the 19-item Highly Sensitive Person Scale (HSPS-J19; Takahashi, 2015) and Adolescent / Adult Sensory Profile (AASP; Tsuji et al, 2015). Results indicate a significant correlation between SPS and two factors (sensory sensitivity and sensory avoidant) of AASP presenting low sensory threshold.
