Study Notes
Memory and Forgetting
- Memory is the persistence of learning over time through the encoding, storage, and retrieval of information
- Three key processes in memory:
- Encoding: forming a memory code, usually requiring attention
- Storage: maintaining encoded information over time
- Retrieval: recovering information from memory stores
- Parallel processing: Our brains process many things simultaneously with some processes occurring unconsciously
-
Measuring retention:
- Recall: retrieving information not in conscious awareness (e.g., fill-in-the-blank test)
- Recognition: identifying previously learned items (e.g., multiple choice test)
- Relearning: learning something more quickly when re-encountered later
- Ebbinghaus's research: More time spent practicing nonsense syllables correlates with less time needed to relearn them
-
Memory-forming process:
- Sensory memory: first stage of memory, receiving information from the environment
- Short-term memory: temporarily holds information while it's being processed, limited in duration and capacity
- Working memory: active scratchpad processing information and linking it with long-term memories
- Long-term memory: relatively permanent storage of memory, unlimited capacity.
- Working Memory-Baddeley's Model: Involves auditory rehearsal, visual-spatial information processing, and a central executive responsible for focusing attention
- Prospective Memory: remembering things to do in the future
- Modified processing model of memory: External events enter sensory memory; attention to important information, rehearsal, and active maintenance leads to encoding into working/short-term memory; long-term memory from this stage
- Encoding memories: Encoding can be effortful (requires attention and conscious effort) or automatic (unconscious)
-
Encoding memories:
- Effortful: Encoding that needs attention/conscious effort
- Automatic: Unconscious/effortless encoding, e.g., space, time, and frequency
-
Sensory memory:
- Iconic: Fleeting sensory memory of visual stimuli, short duration
- Echoic: Fleeting sensory memory of auditory stimuli, tends to linger longer (3-4 seconds)
- Short-term memory capacity: Miller proposed we can hold about 7 pieces of information
- Peterson's research Demonstrated short-term memory has limited duration without active processing (20 seconds)
-
Effortful processing strategies:
- Chunking: organizing information into meaningful units
- Mnemonics: memory techniques to encode difficult material
- Hierarchies: organizing information in categories and subcategories for better recall
- Testing effect: Repeated self-testing improves memory retention
- Distributed practice: Better long-term recall when encoded over time rather than massing
-
Levels of processing:
- Shallow: encoding on a basic appearance level
- Deep: encoding based on meaning
-
Long-term memories:
- Explicit: facts, general knowledge, events
- Semantic: facts and general knowledge
- Episodic: personal experiences
- Implicit: procedural, classical conditioning, emotional
- Explicit: facts, general knowledge, events
- Memory Consolidation: memories move from the hippocampus to other parts of the brain
-
Implicit Memory System:
- Involves cerebellum and basal ganglia
- Associated with forming and storing implicit memories (like classical conditioning)
- Basal ganglia for motor skills
-
Amygdala, Emotions, and Memory:
- Emotions trigger stress hormones, activating the amygdala; crucial for encoding emotionally significant events.
- Stronger emotional events lead to better memory
- Flashbulb memories: detailed, vivid memories surrounding significant, emotionally charged events
-
Amnesia: Memory loss
- Anterograde: inability to create new memories
- Retrograde: inability to recall past memories
-
Constructive memory: memories are reconstructed rather than exact representations of experiences
- Misinformation effect: leading questions/information can distort memories
-
Memory retrieval:
- Memories are interconnected through a web of associations
- Retrieval cues (e.g., smells, tastes, sights) facilitate recall
- Priming: activation of particular associations
- Context-dependent memory: remembering better when in the same context
- State-dependent memory: recalling better in the same state of mind
- Serial position effect: tendency to recall first and last items (primacy/recency) better in a list
-
Forgetting and other memory challenges:
- Interference (proactive, retroactive): old memories hinder new recall, and vice versa
- Encoding failure: information not adequately encoded
- Retrieval problems like tip-of-the-tongue phenomena
- Ebbinghaus Forgetting Curve: illustrates the rapid initial loss of memory, decreasing over time.
