Chapter 8 pt. 1 (EXAM 2) Flashcards
Memory
Set of processes used to encode, store, and retrieve info over different periods of time
Encoding
Recording
Process where brain interprets, organizes, and stores information
ACTIVE PROCESS
Must be effortful processing to be successfully encoded
ATTENTION
Attention is the absolute cost of memory, without attention, it will not be encoded/stored. We ONLY remember things we pay attention to (penny)
Storage
Storing
Maintaining encoded information in memory over time and holding onto it
Information processing theorists describe it as akin to a computer model of memory
3 distinct stages: Sensory memory, STM, and LTM (Atkinson & Shiffrin’s model)
Sensory memory
Stimuli from environment first processed in sensory memory
brief sensory event storage
lost unless encoded with attention
less than 1 second
Short-term memory (STM)
Temporary storage that processes sensory memory (limited)
lasts 15-30 seconds, 5-9 chunks of meaning where new items bump out old ones
Lost unless rehearsed, will last as long as it is rehearsed
Rehearsal
Process that facilitates/leads to transfer of info from STM to LTM
Enough rehearsal will move memory from STM to LTM
2 types: Repetition Rehearsal and Elaborative Rehearsal
Repetition Rehearsal
Repeating info (phone #)
Elaborative Rehearsal
Linking new information to existing information
Working Memory (WM)
Mental workspace to hold and manipulate information
Limited capacity that temporarily stores info to process it
Interference
Distraction, a split of attention that interferes with encoding and storing
Long term Memory (LTM)
Info stored over lifespan, unlimited.
Theory that memory never leaves LTM, just more or less easy to recover it
2 types: Explicit (declarative) and Implicit (procedural) memory
Explicit Memory
Memory, facts, and experiences that can be consciously recalled and declared
2 types: Episodic memory, Semantic Memory
Episodic Memory
Type of Explicit LTM
Events/stories and happenings. Narratives, autobiographical in nature
Dated memory, you have a general gist of the date/time
Semantic Memory
Type of Explicit LTM
Facts, knowledge, and meanings that are often memorized
i.e. capitals of US
Facts are usually not dated
Implicit Memory
Unconscious memories or procedures/skills acquired/used (performance)
3 types:
Procedural memory, Primal memory, and Classical Conditioning
