Memory
| Term | Definition |
|---|---|
| Memory | the persistence of learning over time through the storage and retrieval of information. |
| Recall | a measure of memory in which the person must retrieve information learned earlier, as on a fill-in-the-blank test. |
| Recognition | a measure of memory in which the person need only identify items previously learned, as on a multiple-choice test |
| Relearning | a measure of memory that assesses the amount of time saved when learning material again. |
| Encoding | the processing of information into the memory system—for example, by extracting meaning. |
| Storage | the retention of encoded information over time. |
| Retrieval | the process of getting information out of memory storage. |
| Sensory memory | the immediate, very brief recording of sensory information in the memory system. |
| Short-term memory | activated memory that holds a few items briefly, such as seven digits of a phone number while dialing, before the information is stored or forgotten |
| Long-term memory | the relatively permanent and limitless storehouse of the memory system. Includes knowledge, skills, and experiences. |
| Working memory | a newer understanding of short - term memory that focuses on conscious, active processing of incoming auditory and visual - spatial information, and of information retrieved from long - term memory. |
| Explicit memory | memory of facts and experiences that one can consciously know and “declare.” |
| Effortful processing | encoding that requires attention and conscious effort. |
| Automatic processing | unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings. |
| Implicit memory | retention independent of conscious recollection |
| iconic memory | a momentary sensory memory of visual stimuli; a photographic or picture - image memory lasting no more than a few tenths of a second. |
| echoic memory | a momentary sensory memory of auditory stimuli; if attention is elsewhere, sounds and words can still be recalled within 3 or 4 seconds. |
| chunking | organizing items into familiar, manageable units; often occurs automatically. |
| mnemonics | memory aids, especially those techniques that use vivid imagery and organizational devices. |
| spacing effect | the tendency for distributed study or practice to yield better long - term retention than is achieved through massed study or practice |
| testing effect | enhanced memory after retrieving, rather than simply reading, information. |
| shallow processing | encoding on a basic level based on the structure or appearance of words. |
| deep processing | encoding semantically, based on the meaning of the words; tends to yield the best retention. |
| hippocampus | a neural center located in the limbic system; helps process explicit memories for storage. |
| flashbulb memory | a clear memory of an emotionally significant moment or event. |
| long-term potentiation | an increase in a cell’s firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory. |
| priming | the activation, often unconsciously, of particular associations in memory |
| mood-congruent memory | the tendency to recall experiences that are consistent with one’s current good or bad mood. |
| serial position effect | our tendency to recall best the last and first items in a list. |
| anterograde amnesia | an inability to form new memories. |
| retrograde amnesia | an inability to retrieve information from one’s past. |
| proactive interference | the disruptive effect of prior learning on the recall of new information. |
| retroactive interference | the disruptive effect of new learning on the recall of old information. |
| repression | the basic defense mechanism that banishes from consciousness anxiety - arousing thoughts, feelings, and memories. |
| misinformation effect | incorporating misleading information into one’s memory of an event. |
| source amnesia | attributing to the wrong source an event we have experienced, heard about, read about, or imagined. |
| deja vu | that eerie sense that “I’ve experienced this before.” Cues from the current situation may subconsciously trigger retrieval of an earlier experience. |
