Abstract
Blocking phenomena, calculation stop for several seconds, sometimes appear during the Uchida-Kraepelin tests. Those are considered the result of attention break. We then investigated the detail behavior during blockings using a digital pen and an eye tracking device. With the digital pen, we analyzed the characteristics of handwriting during the tests. Participants were 141 volunteer students in case of Uchida-Kraepelin tests with digital pens and 2 volunteer adults in case of eye tracking analysis. There were 17 blockings in the Uchida-Kraepelin tests of 2 participants wearing the eye tracker. After precise classification of the behavior during blockings, we considered that attention break raised 7 blockings, but not lead to other 10 blockings. We also verified that the behavior during blockings were specific for blocking or not. Almost categorized behaviors were specific for blocking, but one categorized behavior was exclusive to blocking
