AP PSYCHOLOGY

Detailed explanation-1: -When you hear a sound, the audio information enters your echoic memory. It lasts for 2 to 4 seconds before your brain can process the sound. While echoic memory is very short, it helps keep information in your brain even after the sound has ended.

Detailed explanation-2: -Echoic memory: Also known as auditory sensory memory, echoic memeory involves a very brief memory of sound a bit like an echo. This type of sensory memory can last for up to three to four seconds.

Detailed explanation-3: -Echoic memory, or auditory sensory memory, is a type of sensory memory. It’s the ultra-short-term memory of auditory stimuli you’ve just heard. For a brief time, about 4 seconds, the brain registers and temporarily stores a perfect version of the sounds around you until it’s processed.

Detailed explanation-4: -The “short enough” is the length of iconic memory, which turns out to be about 250 milliseconds (1/4 of a second). Auditory sensory memory is known as echoic memory. In contrast to iconic memories, which decay very rapidly, echoic memories can last as long as four seconds (Cowan, Lichty, & Grove, 1990).

Detailed explanation-5: -Echoic memory and iconic memory are sub-categories of sensory memory. Echoic memory deals with auditory information, holding that information for 1 to 2 seconds. Iconic memory deals with visual information, holding that information for 1 second.
