: This study was performed in line with the principles of the Declaration of Helsinki. However, this study has not been granted ethics committee approval because the data were collected at a time when ethical review was not yet generally practiced in Japan. We are planning a follow-up study that uses the same experimental design and procedures except for the addition of an independent variable, and that study was approved by the Ethics Committee of the Tokyo Metropolitan University (No. H3-35).
