Random Gap Detection Test – Standard & Expanded

The RGDT-Standard and Expanded version is an auditory processing disorder test for ages 5 and up using non-verbal stimuli. It is considered a temporal test using temporal resolution and is sensitive to cortical particularly left temporal lobe lesions.

The RGDT-Standard and Expanded includes the standard RGDT in its entirety along with an expanded portion at the end. The expanded portion of the test is included for individuals whose gap detection threshold exceeds 40 msec.  This test begins at time intervals longer than those measured by the standard portion of the RGDT, and includes time intervals of 10 msec. between 40 and 100 msec, and 50 msec. intervals between 100 and 300 msec.  The expanded portion of the test is administered in the same manner as the standard portion.

Individuals who require the expanded portion of the test have already demonstrated abnormal temporal processing abilities. The single purpose is to determine the time interval in which their gap detection thresholds exist. This information can be used to measure improvement in temporal processing abilities following remediation. By definition, patients with temporal processing disorders will have a wide range of gap detection thresholds. Therefore, there are no normative data associated with the expanded portion of the RGDT.

The Random Gap Detection Test-Standard and Expanded includes a) audio recording, and b) manual and score forms as printable pdf files. The 31-page manual pertains to the standard portion of the test. It is comprised of sections on development, background, administration, and interpretation. It includes normative data for ages 5 and up. An additional sheet with sections on administration and interpretation is included for the expanded portion of the test.

Duration Pattern Sequence-Standard Version

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.  Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order. FREE shipping within the contiguous US.

Gaps In Noise (GIN)

The Gaps In Noise (GIN) test is an auditory processing disorder test for ages 7 and older using non-verbal stimuli. It is designed to measure temporal resolution.  Temporal resolution refers to the ability to detect changes either in the duration of an auditory stimulus and/or the time intervals or gaps of silence embedded within an auditory stimulus.  The ability to detect small silent intervals is an important factor in speech perception. This GIN test is a  valuable test for the evaluation of this ability.

The GIN test is composed of a series or lists of noise bursts which contain various intervals of silence.  The recording consists of four forms called lists plus a shorter practice list to ensure the patient understands the task.  The silent intervals vary from 0 (i.e. no gap) to 20 msec.  The gaps, or periods of silence, are 2, 3, 4, 5, 6, 8, 10, 12, 15 or 20 msec.  There are a total of 60 randomized gaps (6 of each gap) in each list (series).

To facilitate accurate scoring the recording is two channels, one being the test track, the other, for the examiner, indicates with a brief tone when the gap occurs in the other (test) track.

The Gaps In Noise includes a) audio recording, and b) instructions and score forms as printable pdf files. The three-page instructions include information on administration, scoring, and interpretation. Normative data is included for ages 8 and up. Available from Auditec, Inc. Call 1-800-669-9065 (from US) or 314-416-1050 (outside the US) to order. FREE shipping within the contiguous US.
