Evaluation of on-board ship handling training using salivary amylase activity

In Japan, an evaluation of on-board ship handling training depends on professionals who have a lot of experience on board. This style is common for human skill practices worldwide. However, it is difficult for a cadet to understand his progress, because real ship training includes every distraction; the same case never happens in his student life. On the other hand, the knowledge is easy to learn. We are looking for an evaluation method to support instructors´ teaching methods and cadets´ progress. Salivary amylase activity shows stress levels in cadets, and we can measure it for one minute. This paper shows the cadet´s and the instructor´s salivary amylase activity together and demonstrates that the salivary amylase activity is a useful index.
