Construction of a Multiple Driving Affective Scale 2018-01-1888
Sensory evaluations of brake characteristics have been performed as solely based on the intuition of professional test drivers, because it was difficult to obtain a consistent response for how general drivers were feeling about brake characteristics. The problem is that there are no scales to measure such the feeling. In the current study, a psychological scale was constructed to measure the affective state of general automobile drivers, for the purpose of clarifying the effects of brake characteristics on the affective state. To construct the affective scale, two experiments were conducted. In the first experiment, a comparison of four types of vehicles was performed, and then an interview survey was performed to broadly collect the evaluation terminology of the affective state. In the second experiment, assessments of the driving scenes was performed by using the evaluation terms obtained in the first experiment, and then a factor analysis based on the assessment value was conducted . For the driving scenes, it was selected 15 scenes that reflected the evaluation items used for brake evaluations. As a result, the affective states were classified as seven factors (active enjoyment, passive enjoyment, anxiety and astonishment, concentration, boredom, affinity, and aversion), with five items attached to each factor, yielding a total of 35 items. However, the factor structures were different between two groups as based on the amount of driving experience. The difference could be considered to be contingent on whether the driving scenes taught in the study had been previously experienced. Therefore, the use of this scale is restricted to test subjects with prior experience with the driving scenes.
