Question | Answer |
---|---|
Memory | an active system that receives information from the senses, puts that information into a usable form, and organizes it as it stores it aways, 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 brains 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 memory in a series of three stages |
levels-of-processing model | model of memory that assumes information that is more or processed according to its meaning rather than just the sound or physical characteristics of the word or words, will be remembered more effeciently and for a longer period of time |
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 |
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 memory | the brief memory of something a person has just heard |
short-term memory(STM) | 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 |
maintenance rehearsal | practice of saying some information to be remembered over and over in ones head in order to maintain it in short- term memory |
long-term memory (LTM) | 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 STM to LTM by making that information meaningful in some way |
procedural(non-declarative) memory | type of long term memory including memory for skills, procedures, habits and conditioned responses (are not conscious but are implied to exist because the 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 knowledge 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 |
semantic network model | model of memory organization that assumes information is stored in the brain in a connected fashion with concepts that are related stored physically closer to each other thatn concepts that are not highly related |
retrieval cue | a stimulus for remembering |
encoding specificity | the tendency for memory of information to be improved if related information available when the memory is first formed is also available when the memeory is being retrieved |
recall | type of memory retrieval in which the information to be retrieved must be "pulled" from memory with very few external cues |
recognition | the ability to match a piece of information or a stimulus to a stored image or fact |
serial position effect | tendency of information at the beginning and end of a body of information to be remembered more accurately than information in the middle of the body of information |
primacy effect | tendency to remember information at the beginning of a body of information better that the information that follows |
recency effect | tendency to remember information at the end of a body of information better than the information at the beginning of it |
false positive | error of recognition in which people think that they recognize some stimulus that is not actually in memory |
automatic encoding | tendency of certain kinds of information to enter long-term memory with little or no effortful encoding |
flashbulb memories | type of automatic encoding that occurs because an unexpected event has strong emotional associations for the person remembering it |
constructive processing | referring to the retrieval of memories in which those memories are altered revised or influenced by newer information |
hindsight bias | the tendency to falsely believe, through revision of older memories to include newer information, that one could have correctly predicted the outcome of an event |
misinformation effect | the tendency of misleading information presented after an event to alter the memories of the event itself |
curve of forgetting | a graph showing a distinct pattern in which forgetting is very fast within the first hour after learning a list and ten tapers off gradually |
distributed practice | spacing the study of material to be remembered by including breaks between study periods |
encoding failure | failure to process information into memory |
retroactive interference | memory retrieval problem that occurs when newer information prevents or interferes with the retrieval of older information |
memory trace | physical change in the brain that occurs when a memory is formed |
decay | loss of memory due to the passage of time, during which the memory trace is not used |
disuse | another name for decay, assuming that memories that are not used will eventually decay and disappear |
proactive interference | memory retrieval problem that occurs when older information prevents or interferes with the retrieval of newer information |
consolidation | the changes that take place in the structure and functioning of neurons when an engram is formed |
retrograde amnesia | loss of memory from the point of some injury or trauma backwards, or loss of memory for the past |
infantile amnesia | the inability to retrieve memories form much before age 3 |
autobiographical memory | the memory for events and facts related to one's personal life story. |
the magic number | seven |
chunking | this is a way to fool short-term into holding more information than is usual such as 657-567-9830 |
state dependent learning | memories formed during a particular physiological or psychological state will be easier to remember while in a similar state |
tip of the tongue phenomenon (TOT) | answers that seem so very close to the surface of conscious thought that it feel its on the tip of the tongue |
anterograde amnesia | the loss of memories from the point of injury or illness forward |
