Sams, Hari, Rif, and Knuutila (1993) performed a neuroscience experiment that employed event-related potential (ERP) recording and determined that the length of memory can be up to 10 seconds long.

Echic nemory

Explanation:

Echoic memory, or auditory sensory memory, is a type of memory that stores audio information (sound).

It’s a subcategory of human memory, which can be divided into three major categories:

-Long-term memory retains events, facts, and skills. It can last for hours to decades.

-Short-term memory stores information you recently received. It lasts for a few seconds to 1 minute.

-Sensory memory, also called the sensory register, holds information from the senses. It can be further broken down into three types:

Iconic memory, or visual sensory memory, handles visual information.

Haptic memory retains information from your sense of touch.

Echoic memory holds audio information from your sense of hearing.

The purpose of echoic memory is to store audio information as the brain processes the sound. It also holds bits of audio information, which gives meaning to the overall sound.
