What is Iconic Memory?
Iconic Memory is a type of sensory memory that stores visual information for an extremely short period (approximately 0.25–0.5 seconds). Its existence was revealed through experiments by psychologist George Sperling in the 1960s.

Why Is It Important?
Iconic memory plays a crucial role in allowing us to experience the world continuously. The reason the world doesn't appear to 'cut out' even when we blink is thanks to iconic memory. During this brief window, the brain selects important information and transfers it to short-term memory.
Everyday Examples
The experience of seeing an entire dark landscape lit up vividly for a split second during a lightning flash, or a car's license plate briefly lingering in your mind as it speeds past — these are iconic memory in action.
