The Duration Pattern Sequence (DPS) -Standard version is an auditory processing disorder test for ages 11 and up using non-verbal stimuli. It is considered a temporal test using auditory pattern temporal ordering (APTO) and is sensitive to cortical lesions, interhemispheric transfer.
Similar to the Pitch Pattern Sequence (PPS) test, the Duration Pattern Sequence (DPS)-Standard also explores pattern perception. However, instead of employing tones of different frequencies, the DPS test uses a single frequency tone at two dissimilar durations. Specifically, each pattern is made up of three 1000 Hz tones of one of two durations. That is, two short, one long or one long, two short, in disparate patterns. There is a total of 60 presentations plus 10 additional patterns for practice.
Duration Pattern Sequence-Standard includes a) audio recording, and b) instructions and score forms as printable pdf files. The one-page instructions consist of administration and interpretation. Normative data is included for adults only. It would be reasonable to expect children over the age of eleven to test as well (or nearly as well) as adults. Available from Auditec, Inc.
