Abstract
      We tabulated upper- and lower-case letter frequency using several large-scale English corpora (~183 million words in total). The results indicate that the relative frequencies for upper- and lower-case letters are not equivalent. We report a letter-naming experiment in which upper-case frequency predicted response time to upper-case letters better than lower-case frequency. Tables of case-sensitive letter and bigram frequency are provided, including common non-alphabetic characters. Because subjects are sensitive to frequency relationships among letters, we recommend that experimenters use case-sensitive counts when constructing stimuli consisting of letters. Case-sensitive frequency tables of single letters and bigrams (including non-alphabetic characters)
