Memory
Question | Answer |
---|---|
Chunking | Organizing items into familiar, manageable unit; often occurs automatically. |
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. |
Long-Term Potentiation (LTP) | An increase in a synapse's firing potential after brief, rapid stimulation. Believed to be a neural basis for learning and memory. |
Amnesia | The loss of memory. |
Implicit Memory | Retention independent of conscious recollection. (Also called procedural memory) |
Explicit Memory | Memory of facts and experiences that one can consciously know and "declare". (Also called declarative memory) |
Hippocampus | A neural center located in the limbic system that helps process explicit memories for storage. |
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 perviously learned, as on a multiple choice test. |
Relearning | A memory measure that assesses the amount of time saved when learning material for a second time. |
Priming | The activation, often unconsciously, of certain associations, thus predisposing one's perception, memory, or response. |
Deja vu | The eerie sense that "I've experienced this before". Cues from the current situation may subconsciously trigger retrieval of an earlier experience. |
Mood-Congruent Memory | The tendency to recall experiences that are consistent with one's current good or bad mood. |
Source Amnesia | Attributing to the wrong source of an event we have experienced, heard about, read about, or imagined. |
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 | In psychoanalytic theory, the basic defense mechanism that banishes anxiety-arousing thoughts, feelings, and memories from consciousness. |
Eyewitness Memory/Testimony | An account given by people of an event they've witnessed. |
Memory | The persistence of learning over time through the storage and retrieval of information. |
Flashbulb Memory | A clear memory of an emotionally significant moment or event. |
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 the 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. |
Automatic Processing | Unconscious encoding of incidental information, such as space, time, and frequency, and of well-learned information, such as word meanings. |
Effortful Processing | Encoding that requires attention and conscious effort. |
Rehearsal | The conscious repetition of information, either to maintain it in consciousness of to encode it for storage. |
Spacing Effect | The tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice. |
Serial Position Effect | Our tendency to recall best the last and first items in a list. |
Semantic Encoding | The encoding of meaning, including the meaning of words. |
Acoustic Encoding | The encoding of sound, especially the sound of words. |
Visual Encoding | The encoding of picture images. |
Imagery | Mental pictures; a powerful aid to effortful processing, especially when combined with semantic encoding. |
Mnemonics | Memory aids, especially those techniques that use vivid imagery and organizational devices. |
Misinformation Effect | Incorporating misleading information into one's memory of an event. |
