Echoic Memory:

Definition:

Echoic memory is a type of sensory memory that refers to the brief retention of auditory or sound information in the sensory system after the original stimulus has ceased.

Subtypes:

• Iconic Echoic Memory: This subtype of echoic memory specifically pertains to the retention of auditory stimuli or sounds.
• Duration: Echoic memory has a relatively longer duration compared to other types of sensory memory, lasting for approximately 2-4 seconds.
• Function: Echoic memory allows individuals to retain and process auditory information, which is crucial for various cognitive processes such as language comprehension and speech perception.
• Capacity: The capacity of echoic memory is limited and can hold a small amount of auditory information, typically within the range of 3-4 items.
• Factors Affecting: The clarity and distinctiveness of the auditory stimulus, attention level, and individual differences can influence the encoding and retrieval of information in echoic memory.
• Neurological Basis: Echoic memory is believed to be supported by the temporal lobes of the brain, specifically the auditory cortex, where auditory information is processed and stored.
