Abstract
This study aims to investigate test-retest reliability or reproducibility of the paper-pencil test for investigating stereotypes of seven principal controls of passenger cars. The controls include wiper, head light, high beam, door window, ignition key, door key and door lock. Sixty two college-aged students participated in the paper-pencil tests and the tests were conducted twice with an in-between period of 4 weeks. The results showed that the stereotypes of motion-directions for the seven controls by the two paper-pencil tests were the same, and that the percentage agreements between two tests by subjects were ranged from 60.0% to 80.6%. There was a weak linear relationship between averaged rates of responses for the stereotypes of motion-directions for the seven controls and percentage agreements by subjects. Based on these results, it is concluded that the paper-pencil test collects reliable or reproducible data on the stereotypes of motion-directions for passenger cars’ controls within four weeks.
