The Dichotic-Consonant/Vowel (D-CV) is an auditory processing disorder test for ages 5 and up using verbal stimuli. It is considered a dichotic test for binaural integration. This test consists of pairs of consonant-vowel (CV) syllables. They are recorded: 1. with simultaneous onset. 2. with staggered onset. In the latter (staggered), one CV leads the other by 90 milliseconds. Three major behavioral measures can be observed: 1. a right ear advantage. 2. A lag effect. 3. An auditory capacity effect.
The Dichotic-Consonant/Vowel includes: a) audio recording, and b) instructions and score forms as printable pdf files. The three-page instructions are comprised of presentation, scoring, and interpretation. Normative data for ages 5 and up is included. Available from Auditec, Inc.
