Abstract
In this study, an implementatin system for the Kraepelin test was built using a microcomputer, and an analysis was made about influence of the data input means over the test result. The system could successfully hundle the proceses ranging from an experiment, statistical analysis to characterization. In addition, a new characterization method was derived through the analysis of the correlation of teh results obtained from this system with those obtained from the conventional hand write test. In future, the effect that is given by key operations about the judgement of character and also methods that are used to analyse the tested data must be considered to pursue by much informaiton.
