Echoic memory

Explanation: Since Jamal's brother was not listening to what he was saying and can still easily recap some of what he said for the last few seconds he is using his echoic memory to recollect those information.

Echoic memory is a type of sensory memory used by the auditory system. Echoic memory can store a large amount of auditory information, but only for few seconds (3 - 4 seconds). This echoic sound is replayed in the brain for this short period of time immediately after the presentation of the auditory stimulus.
