AP PSYCHOLOGY

Detailed explanation-1: -Sensory memory-preserves fleeting impressions of sensorystimuli-sights, sounds, smells, and textures for only a fraction of a second.

Detailed explanation-2: -Iconic memory, or visual sensory memory, holds visual information. It’s a type of sensory memory, just like echoic memory. But iconic memory is much shorter. It lasts for less than half a second.

Detailed explanation-3: -The “short enough” is the length of iconic memory, which turns out to be about 250 milliseconds (1/4 of a second). Auditory sensory memory is known as echoic memory. In contrast to iconic memories, which decay very rapidly, echoic memories can last as long as four seconds (Cowan, Lichty, & Grove, 1990).

Detailed explanation-4: -Sensory memory consists of sensory information retained in an unprocessed form in the sensory system through which it entered. This form of memory is short lived (0.5–3 seconds) but has a large capacity.

Detailed explanation-5: -Sensory memory is a very brief memory that allows people to retain impressions of sensory information after the original stimulus has ceased. It is often thought of as the first stage of memory that involves registering a tremendous amount of information about the environment, but only for a very brief period.
