10101 test 2/memory
gcsc 10101
| Term | Definition |
|---|---|
| Hippocampus | Key brain region for forming new memories/ involved in declarative memories. |
| Anterograde Amnesia | Inability to form new memories due to damage to hippocampus; past intact. |
| Retrograde Amnesia | inability to recall old memories before injury; able to form new memories |
| Types of Long Term Memory | semantic, procedural, episodic, and declarative. |
| Memory Processes | encoding, storage/consolidation, and retrieval. |
| Basal Ganglia | Brain region essential for procedural memory formation. |
| Cerebellum | Coordinates motor control and procedural memory. |
| encoding | converting information into accessible form |
| storage/consolidation | Holding this information in memory for later use memory |
| Retrieval | Taking memories out of storage |
| sensory memory | Storing an exact copy of incoming information for a few seconds; the first stage of memory |
| icon | A fleeting mental image or visual representation |
| echo | After a sound is heard, a brief continuation of the sound in the auditory system |
| short term memory | WORKING MEMORY, similar to RAM in computer |
| Number 7 (Plus or Minus 2): | STM is limited to holding seven (plus or minus two) information bits at once. Information Bits: Meaningful units of information. |
| long term memory | RELEVANCE. Stored on basis of meaning and importance. Infinite amount of storage |
| Digit Span: | Test of attention and short-term memory; string of numbers is recalled forward or backward. Typically part of intelligence tests |
| an example to increase short term memory | chunking |
| sematic | impersonal facts and everyday knowledge-- Days of week/month, names of objects, word, language. |
| procedural | "knowing how" Long-term memories of conditioned responses and learned skills (typing, driving, actions, how-to) |
| episodic | autobiographical Personal experiences linked with specific times and places .autobiographical,-- Harder to remember because constantly new information |
| declarative | "knowing that" (amnesia affects this) LTM section that contains factual information. Names, faces, words, dates, symbols, etc. |
| The 2 parts of declarative are: | semantic and episodic |
| implicit memory | long-term memories that are not part of our consciousness. |
| explicit memory | consciously try to remember, recall, and report |
| encoding failure | When a memory was never formed in the first place |
| memory traces | Physical changes in nerve cells or brain activity that occur when memories are stored |
| memory decay | When memory traces become weaker |
| disuse | Theory that memory traces weaken when memories are not used or retrieved |
| recall | direct retrieval of facts or information - Easiest to remember last items in a list because they are still in STM - Fill-in-the-blank question on tests |
| Distractors: | False items included with a correct item. - Wrong choices on multiple-choice tests |
| recognition | identifies correctly previously learned material - Usually superior to recall - Multiple choice, matching question |
| tip of the tongue | Feeling that a memory is available but not quite retrievable |
| encoding specificity | related information is the same or similar during retrieval as in encoding - Remembering in same environment you stored - Going back to previous place to retrieve "lost" information |
| Alzheimer's | Degenerative Disease of the brain. Amyloid plagues neurons |
| 2 types of amnesia | anterograde and retrograde |
| dementia | general term for a decline in "cognitive ability". - memory loss and thinking difficulties |
| memory mnemonics | Any kind of memory system or aid. |
| repression | Unconsciously pushing painful, embarrassing, or threatening memories out of awareness/consciousness - Motivated forgetting, |
| suppression | Consciously putting something painful or threatening out of mind or trying to keep it from entering awareness |
| serial position effect | Hardest to recall items in the middle |
| recency bias | most likely to recall. usually at end |
