How long is the short version of the visual T.O.V.A. for 4 and 5 year olds?
The visual T.O.V.A. is 11.6 minutes long which is only half of the full test – one quarter of stimulus infrequent and one quarter of stimulus frequent. The auditory T.O.V.A.-A. does not go below 6 years old since research has shown that the hearing spectrum has not developed enough discrimination to differentiate the sounds.
