Study Notes
Memory Lecture Overview
- The lecture covers the nature of memory, forgetting, the biological basis of memory, memory and the criminal justice system, and using psychology to improve memory.
Nature of Memory
- Memory is an internal record or representation of prior events or experiences.
- Memory is a constructive process. Information is actively organized and shaped as it's processed, stored, and retrieved.
Models of Memory
- Information Processing Model: Memory is analogous to a computer with encoding, storage, and retrieval.
- Parallel Distributed Processing (PDP) Model: Memory is distributed across a vast network of interconnected neurons that function in parallel, rather than sequentially. This model is sometimes called the "connectionist" model.
- Levels of Processing: Memory retention depends on the depth of processing. Deeper processing leads to better storage and retrieval. Shallow processing leads to weaker retention.
- Traditional Three-Stage Memory Model: Memory involves three distinct stages: sensory memory, short-term memory, and long-term memory.
Encoding
- Encoding involves taking in sensory information (visual, auditory, semantic).
- Information is stored in memory, either short-term or long-term, depending on the level of attention paid to it and the degree of review or repetition.
- Retrieval involves accessing stored information when needed.
Application in Daily Life
- The model is applicable to understanding study habits. Encoding information effectively and connecting it to existing knowledge are more likely to lead to long-term storage. Consistent review and testing are also useful.
Sensory Memory
- Sensory memory is the briefest stage, holding sensory input (sights, sounds, smells) for a fraction of a second.
- Information quickly fades if not attended to.
- The capacity is large.
Short-Term Memory
- Holds current thoughts.
- Capacity is limited (approximately 5-9 items).
- Can be increased through chunking.
- Information can be stored longer than 30 seconds using maintenance rehearsal.
- STM is also a working memory, including active processing (e.g., visuospatial sketchpad, phonological loop, central executive).
Long-Term Memory
- A relatively permanent storage with unlimited capacity.
- Organization, elaborative rehearsal, and retrieval cues improve LTM.
- Types of LTM include:
- Explicit (declarative): memories with conscious recall (semantic and episodic).
- Implicit (nondeclarative): memories without conscious recall (procedural, classical conditioning, priming).
Forgetting
- Ebbinghaus found that forgetting occurs most rapidly immediately after learning, though relearning is quicker.
- Theories of forgetting include decay theory, interference theory (proactive and retroactive interference), motivated forgetting, encoding failure, and retrieval failure.
Overcoming Problems With Forgetting
- Serial position effect: remembering the beginning and end of a list is better than the middle.
- Source amnesia: forgetting the true source of a memory.
- Sleeper effect: initially discounting information from an unreliable source, later viewing it as reliable.
- Spacing of practice: distributed practice is superior to massed practice.
Biological Basis of Memory
- Changes in neurons (e.g., long-term potentiation) can strengthen synapses and influence neurotransmitter release in long-term memory.
- Hormones affect various brain structures. Flashbulb memories are vivid images of emotionally significant events.
- Memory is localized and distributed throughout the brain.
Biological Causes of Memory Loss
- Amnesia: loss of memory due to brain injury or trauma. This can include retrograde amnesia (loss of past memories) and anterograde amnesia (inability to create new memories).
- Alzheimer's disease leads to progressive mental deterioration, often featuring severe memory loss.
Memory and the Criminal Justice System
- Eyewitness accounts can be very persuasive but flawed.
- Repressed memories are a debated topic regarding accuracy.
Using Psychology to Improve Our Memory
- Strategies include paying attention, using rehearsal techniques, improving organization, managing time, utilizing the encoding specificity principle, employing self-monitoring and overlearning, and using mnemonic devices.
