![]() ![]() This allows for the rapid processing of visual information without conscious effort. Pre-attentive processing: Iconic memory operates at a pre-attentive level, meaning that it functions before conscious attention is directed toward the visual stimuli.This high capacity enables the brain to quickly perceive and process complex visual scenes. ![]() High capacity: Iconic memory can store a large amount of visual information, though the specific capacity varies among individuals.This transient nature helps prevent sensory overload and allows the brain to focus on relevant visual stimuli. Brief duration: Iconic memory lasts for only a fraction of a second, allowing for a seamless flow of visual information but not long-term retention.Iconic memory was first described by psychologist George Sperling in the 1960s, and it plays a crucial role in the initial processing of visual stimuli, acting as a buffer that holds visual information long enough for the brain to process and interpret it.Ĭharacteristics of iconic memory include: It is considered to be the visual counterpart to echoic memory, which serves a similar function for auditory information. Iconic memory is a type of sensory memory that briefly retains visual information for a very short period, typically around 100 to 300 milliseconds.
