The authors devised renewal task of HVMT and named this task HVMT-R. This study we confirmation of reliability and the validity of HVMT-R. Subjects' performances has conventional variables to response time and error scores, and invented 4 valuables to the contact number of time to a side, a corner, whole figure of presentation stimulation : standard figure, and the total number of the contact number of times as same as Kamigaki & Yamazaki (2007). Therefore, it was suggested that HVMT-R was available as the tool which measured a cognitive style of Reflection-Impulsivity.
