Abstract

The psychophysical method of constants was applied to two-handed lifting. A sequence effect was found, with subject's response biased toward which stimulus was presented most recently. This sequence effect drastically reduced the sensitivity of the method for two-handed lifting, so that a further study of comparing sequential and simultaneous lifting was conducted. The results indicated that simultaneous lifting was significantly more sensitive to changes in handle design.
