Because of the interest in testing auditory attention, we have developed a module that can be added to any GDS. It allows the GDS to “speak” the digits that appear on the front display. We have also included an Interference version which introduces auditory distraction to the Vigilance Task. The auditory module uses the very latest in digital synthesis to produce remarkably clear and natural speech. By simply connecting the auditory module to your GDS with a cable, you can administer the following new tasks:

Auditory Vigilance Task -- Identical to the standard (visual) Vigilance Task except that the subject responds to numbers that are heard instead of seen. To administer the task, the examiner covers the front display of the GDS (cover supplied) and places headphones (also supplied) on the subject’s head. All scores for the auditory version are gathered and calculated the same as for the standard task.

Auditory Interference Task -- Instead of saying the precise number that appears on the front display, this task generates a random number through the headphones. The subject performs on the standard Vigilance (or Distractibility) tasks while having to contend with the confusing auditory input.

Considered in the context of other clinical information, GDS data help the practitioner evaluate the impulsivepatient, generate treatment recommendations, and assess therapeutic outcome. It can be particularly useful in establishing levels of severity and in identifying the "well behaved" child with serious attention deficits. Objective data are also helpful when ratings from parents and teachers are clouded by disagreement or when the credibility of such reports is in doubt. GDS scores have also been found useful in the monitoring of pharmacotherapy.

GDS Printer
This printer is extremely small (4" w x 4.5" l x 2" h), light (16 oz.) and reasonably priced. While the GDS can display data without a printer, it is programmed to format automatically all summary and tracking data for printer output. No more hand scoring or tabulations! This printer comes with a 90-day manufacturer's warranty. The auditory module comes with a cable designed for GDS units with a 9-pin connector.
