CHILD DEVELOPMENT PEDAGOGY

Detailed explanation-1: -Sensory memory-preserves fleeting impressions of sensorystimuli-sights, sounds, smells, and textures for only a fraction of a second. Long-Term memory-preserves information for retrieval at any time. The information may be stored for an entire life time and constitutes ourknowledge about the world.

Detailed explanation-2: -Short-term memory lasts a fraction of a second before the information is lost.

Detailed explanation-3: -Sensory memory. Sensory memory preserves incoming sensory information (in its original sensory form) for only a fraction of a second. (A visual memory trace is called an icon; an auditory memory trace is called an echo.)

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: -The “short enough” is the length of iconic memory, which turns out to be about 250 milliseconds (¼ 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).
