(4) The sequential nature of substitution errors was further analyzed by tallying and classifying errors as anticipatory (prepositioning), reiterative (postpositioning), or metathesis.
Transposition
Definition:
(n.) The act of transposing, or the state of being transposed.
(n.) The bringing of any term of an equation from one side over to the other without destroying the equation.
(n.) A change of the natural order of words in a sentence; as, the Latin and Greek languages admit transposition, without inconvenience, to a much greater extent than the English.
(n.) A change of a composition into another key.
Example Sentences:

(4) Together these rearrangements occur at about 10% the rate of IS10 transposition.
(5) A final experiment confirmed a prediction from the above theory that when recalling the original sequence, omissions (recalling no word) will decrease and transpositions (giving the wrong word) will increase as noise level increases.
