Abstract
The first study was carried out to examine a hypothesis: there is a positive relationship between internality and pro-environmental orientation. Internality and pro-environmental orientation were respectively measured by means of a Japanese version of Rotter's locus of control scale and a 34-item five-point scale which had five dimensions of pro-environmental attitudes. Data was collected from 163 Japanese undergraduates and the hypothesis was generally supported. The second study tested a hypothesis: there is a positive relationship between noise sensitivity and pro-environmental orientation. Noise sensitivity as a personal disposition was measured by a 21-item five-point scale and the same pro-environmental orientation measures were obtained as were in the first study. Data was collected from 147 undergraduates and this hypothesis was also evidenced.
