Repeating a phone # to keep (cid:862)fresh(cid:863) in the mind. Sensory memory: holds i(cid:374)put i(cid:374)fo re(cid:272)ei(cid:448)ed i(cid:374) its origi(cid:374)al (cid:862)u(cid:374)e(cid:374)(cid:272)oded(cid:863) for(cid:373, info is lost within to 3 secs, visual less than a second, auditory less than 2 - 3. Long term memory (cid:862)procedural (cid:373)e(cid:373)ory(cid:863: stores our general knowledge, some info may be lost over time, interconnected with other information. 2 or more other things might come to mind: information can be encoded as words, sounds, smells, images, procedures, or meanings, controls our behavioral performance, ex. Explicit knowledge: knowledge easily recallable and explainable. Implicit knowledge: knowledge we cannot recall or explain. Saccades = (cid:862)ju(cid:373)ps(cid:863) i(cid:374) fo(cid:272)us: occur 4-5 times per second, visual & audio sensory (cid:862)me(cid:374)tal filli(cid:374)g i(cid:374)(cid:863) allow for smooth vision. Audio sensory store: even if not processing, it is still held for a few seconds.

Perception: the (cid:862)(cid:373)ea(cid:374)i(cid:374)g(cid:863) or interperetation we impose on a situation.
