2.4 - Types and Processes of Memory Encoding

explicit memory

retention of facts and experiences that we can consciously know and "declare." (Also called declarative memory.)

Effortful processing

encoding that requires attention and conscious effort.

automatic processing

unconscious encoding of incidental information, such as space, time, and frequency, and of familiar or well-learned information, such as sounds, smells, and word meanings.

implicit memory

retention of learned skills or classically conditioned associations independent of conscious recollection. (Also called nondeclarative memory.)

iconic memory

a momentary sensory memory of visual stimuli; a photographic or picture-image memory lasting no more than a few tenths of a second.

echoic memory

a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds.

chunking

organizing items into familiar, manageable units; often occurs automatically.

mnemonics

memory aids, especially those techniques that use vivid imagery and organizational devices.

spacing effect

the tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice.

testing effect

enhanced memory after retrieving, rather than simply rereading, information. Also referred to as a retrieval practice effect or test-enhanced learning.

shallow

encoding on a basic level, based on the structure or appearance of words.

deep

encoding semantically, based on the meaning of the words; tends to yield the best retention.

semantic encoding

understanding the meaning of something.
