Swedish norms for completion of word stems and unique word fragments.
Swedish norms for completion of word stems and single-solution word fragments, with few or many letters specified, were obtained from Swedish students. Comparisons were made for completion rates between stems and fragments that were possible to complete with the same word. As expected, completion rates for fragments were generally superior to those of word stems since the word stems allowed alternative completions. Adding one letter to the word stems and fragments resulted in a significant increase in the probability of completion, for both stems and fragments. A stepwise regression analysis was conducted in order to partial out factors determining the completion probability for fragments. The ratio of specified letters to blank characters, and the familiarity of the solution was found to be the most important factors. Finally, the effect of number of given letters in the word stem on the number of generated words per stem was studied. The mean number of words generated per stem was found to be equal for both two- and three-letter word stems.
