Identity Correspondences for Ponto

This set of correspondences is intended for comparing responses directly to orthography, namely, the correct or standard spelling. It is a very basic character-for-character mapping from stimulus to response. Any single character in the stimulus can be matched with the same character in the response, with penalty 0. Case is distinctive, and diacritics are treated as separate characters. All characters are counted, even punctuation; the only thing ignored is white space at the beginning or end of the response cell. For example, the table contains the following entities:

stimulusresponsepenalty
aa0
AA0
^^0
--0

Thus spelling “cat” as “cat” would receive no penalty; spelling “cat” as “Cat” would receive a substitution penalty. “chá” would be considered a 4-character stimulus; spelling it as “cha” would receive one deletion penalty; spelling it as “cho” would receive a deletion penalty and a substitution penalty. If you do not in fact want to count off for case differences, edit your Trials to put all stimuli and responses in the same case. If you want to ignore diacritics or punctuation, delete them from the Trials.

Fine Points

The program processes the data in Unicode Normalization Form D. Thus “á” is treated as two characters even if entered as the single Unicode character U+00E1.

The program can be used for all character sets, not just Latin.
