Abstract
Taken together with earlier work on command naming, Grudin and Barnard's results suggest that “specificity” and “meaningfulness” may be important while “naturalness” is not. However, important methodological problems are raised by experiments like this, in which conditions are arranged to maximize the effect of theoretically interesting variables while reducing overall similarity to real tasks.Keywords
