Study into Relationship between Uchida–Kraepelin Psychodiagnostic Test Results and Number of Blinks
Data generated by automatically and quantitatively evaluating subjects’ mental and physical conditions can contribute to the improvement of quality of life. The Uchida–Kraepelin psychodiagnostic test not only estimates the individuality of a person but also reflects their mental and physical conditions. To associate the results of this test with objective data, the relationship between the number of blinks and the number of calculations a subject was able to perform in a specific time period was investigated. Analysis of the experimental results indicated that: (a) there was a negative correlation between the number of calculations and number of blinks; (b) the “late increase rate” indicated by the Uchida–Kraepelin psychodiagnostic test was also reflected in the test medium of using a personal computer (PC); (c) there was a significant difference in the number of blinks recorded between the first and second testing periods; and (d) excluding outliers was an effective approach to more reliable detection of significant differences between the first and second testing periods.
