Pitch Pattern Sequence

The standard Pitch Pattern Sequence (PPS) test is an auditory processing disorder test using non-verbal stimuli. It is considered a temporal test using auditory pattern temporal ordering (APTO) and is sensitive to cortical lesions, interhemispheric transfer.

It consists of a series of three tones presented at either of two frequencies (pitches). The subject’s task is to describe the pitches of the tones presented. The test is a monaural test that evaluates both pattern perception and temporal sequencing ability while excluding verbal cues. Relative hemispheric involvement can often be observed by having the patient give a motor response (usually verbal) in the first trial and a humming response for the second trial.

The standard Pitch Pattern Sequence is available in two versions: 1) Adult Version for ages 9-65, and 2) Child Version for ages 6-9. Each version is sold separately. Therefore, it is necessary to specify the version or item number when ordering. The Pitch Pattern Sequence includes a) audio recording, b) instructions and score forms as printable pdf files. The two-page instructions include administration, scoring, and interpretation information. Normative data is included for the ages that correspond to the test version.
