As ships have larger mass and tend to suffer disturbance forces of wind, wave and so on, they are regarded as "time lag system" from the point of view of human operation. In order to investigate this field, we have organized the project team which included psychology, naval architecture, marine traffic engineering and human engineering. We have already published the findings of the project in this journal several times as follows. A) The participants made more exact responses under short time lag than long time lag. B) The most difficult situation was the case that involved three conditions simultaneously (slow cursor speed, large time lag and bad brake efficiency). However, our findings leave questions which the participants accuracy of response does not describe the usual learning curve. Then we improved the apparatus and carried out experiments controlled stringently. The findings revealed that the participants accuracy of response described the usual learning curve under no and short time-lag (3 sec) in contrast with highly specific curve under larger time lag (over 10 sec). These findings suggested that mental work load might be higher in time lag system than in the other situation.
