Memory: Model, Processes, & Forgetting Flashcards
memory
an active system that receives information from the senses, puts that information into a usable form, organizes it as it stores it away, and then retrieves the information from storage
encoding
the set of mental operations that people perform on sensory information to convert that information into a form that is usable in the brain’s storage systems
storage
holding onto information for some period of time
retrieval
getting information that is in storage into a form that can be used
information-processing model
model of memory that assumes the processing of information for memory storage is similar to the way a computer processes memore in a series of three stages
parallel distributed processing model (PDP)
a model of memory in which memory processes are proposed to take place at the same time over a large network of neural connections
levels-of-processing model
model of memory that assumes information that is more “deeply processed,” or processed according to its meaning rather than just the sound or physical characteristics of the word or words, will be remembered more efficiently and for a longer period of time
sensory memory
the very first stage of memory; the point at which information enters the nervous system through the sensory systems
iconic memory
visual sensory memory, lasting only a fraction of a second
eidetic imagery
the ability to access a visual memory for 30 seconds or more
echoic imagery
the brief memory of something a person has just heard
short-term memory
the memory system in which information is held for brief periods of time while being used
selective attention
the ability to focus on only one stimulus from among all sensory input
working memory
an active system that processes the information in short-term memory
maintenence rehearsal
practice of saying information to be remembered over and over in one’s head in order to maintain it in short-term memory
long-term memory
the system of memory into which all the information is placed to be kept more or less permanently
elaborative rehearsal
a method of transferring information from the short-term memory into the long-term memory by making that information meaningful in some way
procedural (nondeclarative) memory
type of long-term memory including memory for skills, procedures, habits, and conditioned responses; these memories are not conscious but are implied to exist because they affect conscious behavior
anterograde amnesia
loss of memory from the point of injury or trauma forward, or the inability to form new long-term memories
implicit memory
memory that is not easily brought into conscious awareness, such as procedural memory
declarative memory
type of long-term memory containing information that is conscious and known
semantic memory
type of declarative memory containing general knowledgy, such as knowledge of language and information learned in formal education
episodic memory
type of declarative memory containing personal information not readily available to others, such as daily activities and events
explicit memory
memory that is consciously known, such as declarative memory
