Chapter 8 - Memory Flashcards
memory
the set of processes used to encode, store, and retrieve information over different periods of time
encoding
- the input of information into the memory system
- organize the information with other similar information and connect new concepts to existing concepts
automatic processing
encoding of details without any conscious awareness
effortful processing
requiring a lot of work and attention in order to encode information
semantic encoding
The encoding of words and their meaning
visual encoding
the encoding of images
acoustic encoding
the encoding of sounds, words in particular
self-reference effect
the tendency for an individual to have better memory for information that relates to oneself in comparison to material that’s less personal
storage
- the creation of a permanent record of information
- i.e. long term memory
sensory memory
- storage of brief sensory events, such as sights, sounds, and tastes
- very brief storage (a few secs)
short-term memory (STM)
- a temporary storage system that processes incoming sensory memory
- lasts 15-30 sec
rehearsal
- moves information from short-term memory to long-term memory
- Active rehearsal is a way of transferring info, will go to long term if repeated enough
long-term memory (LTM)
- the continuous storage of information
- believed to have unlimited capacity
explicit memories
- those we consciously try to remember, recall, and report
- ex. material on test you’re studying for
episodic memory
- information about events we have personally experienced
- recollection of visual imagery, often a story
semantic memory
- knowledge about words, concepts, and language-based knowledge and facts
- typically facts
implicit memories
- long-term memories that are not part of our consciousness
- demonstrated in the performance of some task, usually not consciously recalled
procedural memory
- stores information about the way to do something, and is the memory for skilled actions
- type of implicit memory, studied w/observable behavior
engram
the group of neurons that serve as the “physical representation of memory”
equipotentiality hypothesis
guess that if part of one area of the brain involved in memory is damaged, another part of the same area can take over that memory function
amygdala in memory formation
- plays a part in how memories are stored because storage is influenced by stress hormones
- main job of the amygdala is to regulate emotions
hippocampus and memory
- is involved in memory, specifically normal recognition memory and spatial memory (when the memory tasks are like recall tests)
- project information that give memories meaning and connect them w/memories
- transfers new learning to long term memory
