STM Working Memory
| Term | Definition |
|---|---|
| Working Memory | The use of STM as a temporary store for info needed to accomplish a particular task |
| Interference Theory | Proposal that forgetting occurs because other material interferes with the info in memory |
| Decay Theory | Proposal that info is spontaneously lost over time, even when there is no interference from other material. |
| Retroactive Interference | Forgetting that occurs because of interference from material encountered after learning |
| Proactive Interference | Forgetting that occurs because of itnereference from material encountered before learning. |
| Release from Proactive Interference | Reducing proactive interference by having info be dissimilar from earlier material. |
| Memory Span | The number of correct items that people can immediately recall from a sequence of items. |
| Absolute Judgement Task | ID stimuli that vary along a single, sensory continuum. |
| Chunks | A cluster of items that has been stored as a unit in LTM. |
| Acoustic Code | A memory code based on the sound of the stimulus. |
| Semantic Code | A memory coe based on the meaning of the stimulus. |
| Acoustic Confusion | An error that sounds like the correct answer. |
| Phoneme | Any of the basic sounds of a language that are combined to form speech. |
| Subvocalizing | Silently speaking to oneself. |
| Lexical Alteration | Substituting a word with a similar meaning for one of the words in a sentence. |

| Self-terminating Search | A search that stops as soon as the test item is successfully matched to an item in the memory set. |
| Exhaustive Search | A search that continues until the test item is compared with all items in the memory set. |
| Encode | To create a visual or verbal code for a test item so it can be compared with the memory code of items sotred in short-term memory. |
| Scan | To sequentially compare a test item with items in STM to determine if there's a match. |
| Slope | A measure of how much response time changes for each unit of change along the x-axis (memory-set size) |
| Phonological Loop | A component of Baddeley's working memory model that maintains and manipulates acoustic information. |
| Visuospatial Sketchpad | A component of Baddeley's working memory model that maintains and manipulates visual/spatial info. |
| Central Executive | A component of Baddeley's working memory model that manages the use of working memory. |
| Multimodal Code | An integration of memory codes such as combining visual and verbal codes. |
