What is the duration of iconic memory typically described as?

Iconic memory is a type of sensory memory that specifically pertains to visual information. It is characterized by a very brief duration, typically lasting only a fraction of a second. This allows the brain to retain a visual image long enough to process it before it fades away. The correct description of the duration of iconic memory is often around 250 milliseconds to 500 milliseconds. Understanding iconic memory is crucial in the study of cognitive processes because it highlights how we capture and initially process visual stimuli in our environment. Other time frames like seconds, minutes, or hours do not accurately reflect the fleeting nature of this specific type of memory, which is why they do not accurately describe iconic memory's characteristics.
