Unit 2 part 2 cognition

memory

persistence of learning over time through the encoding, storage, and retreival of information

alzheimers disease

diffucultly in retaining memeories and eventually destroys memory

recall

retrieving info that is not currently in your conscious awareness but that is learned at an earlier time( fill in the blank question)

recognition

identifying something you already learned(multiple choice or matching)

relearning

learning something moe quickly when you learn it a second or later time

encoding

getting info into memory system

storage

retainging info over time

retrieval

getting info out of memory storage

sensory memory

immediate, very breif recording of sensory information

short term memory

memory that holds a few items breifly before info is stored of forgotten

Long Term memory

relatively permanent and limitless storehouse of the memory system

working memory

newer/extended understanding of short term memory

links new experiences tro long term memories

like a temporary sticky note in the brain for holding info

central executive

memory component that coordinates the actvities of the phonological loop and visuospatial sketch pad

phonological loop

a memory component that briefly holds auditory information

visuospatial sketchpad

memory component that briefly holds info about objects appearance and location in space( route from school to home)

episodic buffer

integrates info from different sources to create a detailed representation of an event or experience

encoding memories

explicit vs implicit

explicit memory

retention of facts and experiences that we can consciously know and declare(uses hippocampus)

effortful processing( requires attention)

with conscious awareness

implicit

retention of learned skills or classically conditioned associations independent of conscious recollection (uses cerebellum)

automatic processing (unconscious endcoding of incidental info)

w/o conscious awareness

implicit memory types

1. procedural memories: automatic skills( riding a bike)

2. association: classically conditioned fears( if you throw up from oysters, in future the smell of them makes you nauseuos)

iconic memory

momentary sensory memory of visual stimuli( picture/image memory)

echoic memory

a momentary sensory memory of auditory stimuli( sounds and words)

short term memory capacity

can hold a little less or more than 7 peices of info for less than 30 seconds

chunking

organizing items into familiar, manageable units
