Question

Which of the following is / are demonstrated by dichotic listening experiments?

• A. Selective auditory attention
• B. Left ear dominance for speech sounds
• C. Right ear dominance for speech sounds
• D. Left hemisphere dominance for speech sounds

Hint:

Dichotic listening supports the idea that the left hemisphere is dominant for processing speech and demonstrates right ear advantage and selective attention mechanisms.

Answer 1

The Correct Option is A, C, D

Step 1: Understanding dichotic listening.
In dichotic listening tasks, different auditory inputs are presented to each ear simultaneously. Participants typically report hearing the stimulus from the right ear more accurately and frequently when the input is verbal.
Step 2: Interpretation.
The preference for right ear input indicates right ear dominance for speech sounds (C).
This right ear advantage is linked to the left hemisphere's dominance for language processing (D).
The task also involves focusing attention on one stimulus, showing selective auditory attention (A).
(B) is incorrect because speech sounds are more dominant in the right ear, not the left.
