cABR/FFR

Question 1

According, to Skoe and Kraus (2010), which of the following analysis techniques is used to track how the response changes over time?

Answer 1

Sliding window analysis

Question 2

What duration do Skoe & Kraus (2010) recommend for the poststimulus period?

Answer 2

10-50 ms

Question 3

T/F: Click-ABRs are more sensitive to auditory impairments than ABRs elicited by speech.

Answer 3

False

Question 4

Differences the encoding of speech syllables can be represented in the brainstem through all but the following.

Answer 4

Through differences in frequency energy.

Question 5

According to Anderson et al., 2010 (discussed in lecture), how does noise affect speech-evoked brainstem responses in children who have difficulty hearing in background noise?

Answer 5

Delayed latencies in noise

Question 6

According to tonotopicity of the cochlea, what would be expected latencies for /ga/, /ba/, and /da/?

Answer 6

/da/ latencies would occur earlier than /ba/ latencies

Question 7

According to Skoe and Kraus (2010), what is the recommended stimulus presentation level for the cABR?

Answer 7

60-80 dB SPL

Question 8

T/F: cABRs can be elicited by both synthetic and natural speech stimuli.

Answer 8

True

Question 9

T/F: When testing with the cABR, duration of speech stimuli should be 40 ms or less.

Answer 9

False

Question 10

T/F: When testing with the cABR, optimal stimulus frequency would be greater than 300 Hz.

Answer 10

False

Question 11

What analysis paradigm would potentially be most appropriate for screening for autism, given that kids with ASD often exhibit difficulty understanding meaning denoted by prosody?

Answer 11

Pitch tracking to a changing contour

Question 12

Compared to younger adults, the FFRs of older adults are characterized by all but the following:

Answer 12

Earlier latencies in noise
