Redundancy in language reduces the possiblity of error and permits communication where there is interference in the communicating channel. The relationship between creativity (the basic distinction between language-like behavior and knowing a language) and redundancy has been clearly established. Knowledge of rules is the key factor in creativity…

Classical cloze tests have been criticized as unsatisfactory operationalizations of the concept of reduced redundancy and the theory of expectancy grammar. Use of the C-Principle is proposed as an improvement over the classical cloze procedure. Such tests are constructed according to a technique that deletes the second half of every second word in…

One solution to the problems of discrete-point testing are tests of reduced redundancy, that is, tests that introduce interference into the communication through actual introduction of noise or through deletion of text and that ask the learner to perform in spite of the noise. Three test types were originally developed to operationalize the…

Compares the empirical performance of C-tests with other representatives of the family of reduced redundancy tests--classical cloze, cloze-elide, multiple-choice cloze--using the Duisburg English Language Test for Advanced Students as the criterion for empirical validity. Findings reveal that the C-Test emerges as the most economical and reliable…
