Memory Encoding & Storage
Organizational Encoding
breaking down complex info into broad concepts and further dividing those (i.e., hierarchy- animal web)
Encoding and Specificity
info is retrieved more easily in the same context that it was learned (scuba diver example)
Long-Term Memory
essentially unlimited capacity store, with the contents typically encoded by meaning
Short-Term/Working Memory
has a limited capacity and short duration; can store 7 +/- 2 meaningful items at once -Rehearsal: mental repetition of info -Chunking: combining small pieces of info into larger clusters/chunks
Visual Encoding
using mental pictures (imagery) to aid effortful processing -mnemonic techniques use vivid imagery in aiding memory
Explicit VS. Implicit Memory (both LT)
*Explicit Memory- conscious or intentional retrieval of info; consists of Semantic Memory (facts/general knowledge) + Episodic Memory (personal experiences) *Implicit Memory- UNconscious or UNintentional retrieval of info; consists of Procedural Memory (motor and cognitive skills) + Priming (enhanced identification of objects/words) + Classical & Operant Conditioning
Long-Term Memory Systems
-Long Term Memory: 1) Explicit (with conscious recall) 2) Implicit (without conscious recall) -Explicit: a. Semantic (facts & general knowledge) b. Episodic (personally experienced events) -Implicit: a. Procedural (motor & cognitive skills) b. Priming (enhanced identification of objects/words) c. Classical & Operant Conditioning
Retrieval Cues
-external info that is associated with stored info and helps bring it to mind; memories are held in storage by a web of associations (fire-truck example) -Priming: to retrieve a specific memory from the web of associations, you must first activate one of the strands that leads to it (ex: seeing or hearing the word "rabbit" -> activates concept -> primes spelling the spoken word "hair/hare" as h-a-r-e)
Elaborative Encoding
-process of actively relating new info to KNOWLEDGE that's already in memory (semantic encoding results in better retention than visual or acoustic encoding) -self-reference effect: the facilitation of memory that occurs when people relate information to their self-concept (demonstrates the power of elaborative encoding)
Amnesia (2 types)
1) Anterograde Amnesia= cannot form new memories, but show signs of unconscious learning (usually permanent) 2) Retrograde Amnesia= cannot remember old memories (less likely to be permanent); example- The Vow
The Brain & Memory (3 parts)
1) Hippocampus: helps process explicit memories 2) Cerebellum: helps process implicit memories 3) Amygdala: helps process emotional memories
Retrieval (3 types)
1) Recall- assesses ability to retrieve previously learned info (ex: fill in the blank) 2) Recognition- assesses ability to identify previously learned info (ex: multiple choice) 3) Relearning- assesses amount of time saved after learning material a second time
Memory Effects (2)
1) Spacing Effect: we retain info better when we rehearse over time 2) Serial Position Effect a. Immediate Recall: we remember last items best (recency effect) b. Later Recall: we remember first items best (primacy effect)
Sensory Memory (2 types)
brief memory of what you just saw/heard -Iconic Memory: fast-decaying store of VISUAL info, lasts a few tenths of a second -Echoic Memory: fast-decaying store of AUDITORY info, lasts 3-4 seconds
Long-Term Potentiation
enhanced neural processing that results from the strengthening of synaptic connections; may provide neural basis for learning and memory
Memory (3 parts)
persistence of learning over time through the encoding, storing, and retrieving of information (computer analogy)
Encoding & Different Types of Encoding
process by which we transform what we perceive, think, or feel into an enduring memory -3 Types: 1) elaborative encoding 2) visual encoding 3) organizational encoding
Storage & Different Types of Storage
process of maintaining info in memory over time -3 Types: 1) Sensory Memory 2) Short-Term/Working Memory 3) Long-Term Memory
Moods and Memories: State-Dependent Retrieval
tendency to recall info more easily when in the mental state that it was learned (retrieving info in a sad mood will increase the likelihood that you will recall sad stories)
Automatic and Effortful Processing
we often have to exert mental effort to remember info, but we also remember a large amount of info without effort. -space: we remember where things were located -time: we remember the order of daily events -frequency: we remember how often things occur
