Auditory brainstem responses to complex sounds (cABRs) • Stimuli in the literature: • Vowels (both synthetic & natural) • CV syllables (synthetic, natural, & hybrid) • Words (ex: car, rose, chair) • Phrases (ex: chicken pot pie) • Environmental sounds • Non-speech vocal sounds (ex: a baby’s cry • Musical sounds and melodies Clinical Applications: The cABR is replicable across test sessions and reliably measured under passive conditions using a small number of electrodes. • Identify individuals likely to benefit from auditory training. • Assessment and documentation of treatment outcomes. • Objective test for evaluating speech-in-noise. • Possibly provide early identification of children with auditory processing deficits that lead to learning …show more content…
Spectral amplitudes were calculated over 3 ranges of frequencies: Low (75–175), mid (175–750), and high (750–1050 Hz). If the BioMARK results are ABNORMAL: • May be a good candidate for auditory-based intervention training. • Russo et al. (2005) performed cABRs on dyslexic children before and after auditory training. Results showed that auditory training can alter the neural encoding of complex sounds by improving neural synchrony in the auditory brainstem. • Earobics: a commercial auditory training program that provides training through interactive computer games of phonological awareness, auditory processing, and language processing skills. If the BioMARK results are normal, but other types of behavioral tests suggest that the child has auditory-based learning problems: • Studies at Northwestern University showed that 70% of children with diagnosed learning problems had normal BioMARK responses. • No single test, including BioMARK, assesses all of a child’s abilities.
