Study Notes
Introduction to Memory
- Memory is a complex cognitive process with various models and theories to explain its mechanisms.
- Evaluating these models and theories is crucial to understand their strengths and weaknesses and appreciate the limitations of our current knowledge about memory.
- Memory involves encoding, storage, and retrieval of information.
Multi-Store Model of Memory
- Proposed by Atkinson and Shiffrin (1968).
- Suggests that memory consists of three separate stores: sensory register, short-term memory (STM), and long-term memory (LTM).
- Sensory register: briefly holds sensory information.
- Short-term memory (STM): holds information for a limited duration (about 18-30 seconds) and capacity (about 7 +/- 2 items). Encoding primarily involves acoustic coding.
- Long-term memory (LTM): a permanent store with unlimited capacity. Information can persist for a lifetime. Encoding primarily involves semantic coding (but can include visual and acoustic).
- Information flows from the sensory register to STM; if rehearsed, it moves to LTM.
- Key features of the model: separate stores, sequential processing, and limited capacity of STM.
- Criticized for oversimplifying memory and failing to account for various processing ways, and for being overly simplistic, lacking consideration of emotional factors, and prior knowledge.
Types of Long-Term Memory
- Episodic memory: stores personal experiences, characterized by temporal context. (e.g., your first day of school)
- Semantic memory: stores general knowledge about the world. (e.g., capital of France)
- Procedural memory: stores information about how to do things, often requiring little conscious awareness (e.g., riding a bike)
- These are distinct memory systems, each with its own function and characteristics. Interaction between these types of memories is also possible.
Working Memory Model
- Developed by Baddeley and Hitch (1974).
- Suggests that STM is not a unitary store but a complex system with multiple components working together:
- Central executive: directs attention, controls and coordinates processes.
- Phonological loop: processes auditory information and verbal material. It consists of a phonological store (inner ear) and articulatory rehearsal process (inner voice).
- Visuospatial sketchpad: processes visual and spatial information. It comprises a visual cache and an inner scribe.
- Episodic buffer: integrates information from different components, acting as a temporary store.
- It proposes a more active and flexible view of memory compared to the multi-store model.
- Emphasizes the importance of different components in processing information.
- Faces challenges in fully explaining complex cognitive processes. Overly simplistic, failing to consider emotional factors and prior knowledge.
Encoding Specificity Principle
- States that the effectiveness of retrieval cues is directly related to the similarity between the encoding context and the retrieval context.
- Successful retrieval is more likely when the context at retrieval is consistent with the encoding context. (e.g., taking an exam in the same room as learning the material).
- It highlights the importance of encoding context cues, in relation to effective retrieval. Retrieval cues and context are crucial.
Factors Affecting Retrieval
- Retrieval cues: stimuli that help in retrieving stored information. Matching encoding and retrieval contexts is a powerful retrieval cue.
- Context-dependent forgetting: the inability to recall information when the encoding and retrieval contexts differ.
- State-dependent forgetting: the inability to recall information when the physiological state (e.g., mood, intoxication) at encoding and retrieval differ.
- Emotional factors: emotions can affect memory encoding and retrieval. Strong emotions often result in more vivid and detailed memories.
- The strength of memory traces is crucial to retrieval.
- Mood affects encoding, storage, and retrieval processes (mood-congruent recall).
- Level of processing, emotional state, and context during encoding affect memory strength and accuracy.
Forgetting
- The inability to recall previously stored information.
- Several theories explain forgetting, including interference theory (proactive and retroactive interference), decay theory, and retrieval failure theory.
- Proactive interference: previously learned information interferes with the ability to learn new information.
- Retroactive interference: newly learned information interferes with the ability to recall previously learned information.
- Decay theory: memories fade over time if not rehearsed.
- Retrieval failure: inability to access stored information due to insufficient cues or lack of retrieval strategies.
- Interference varies based on material similarity and encoding strategies. Context is crucial.
Eyewitness Testimony
- Eyewitnesses can be unreliable sources of information about events.
- Factors like leading questions, misinformation, and reconstructive memory can distort memories of events.
- Leading questions: questions phrased in a way that suggests a particular answer.
- Misinformation: misleading information presented after an event.
- Reconstructive memory: memory is not a direct copy of an event, but a reconstruction from various sources of information.
- Factors such as anxiety, leading questions, and misinformation can influence eyewitness accuracy.
Improving Memory
- Mnemonic devices: strategies to aid in encoding and retrieval of information.
- Organization and rehearsal: processing information in an organized way and practicing it repeatedly.
- Elaboration: linking new information to existing knowledge.
- Using imagery: creating mental images that connect with the information.
- Self-testing: assessing your knowledge of information through answering questions.
- Sleep and rest: allow sufficient time for the brain to consolidate memories.
Reliability and Validity of Memory Studies
- Laboratory experiments often lack ecological validity, meaning that findings may not generalize to real-world situations.
- Participant variables, such as individual differences in mood and motivation, can influence results and affect the reliability of conclusions.
- Some memory studies rely on self-report measures, which are susceptible to biases like social desirability.
Ethical Considerations in Memory Research
- Deception of participants, although sometimes necessary for certain research designs, can raise ethical concerns and potentially cause distress.
- The potential for psychological harm from recalling traumatic events should be carefully considered before conducting such research.
- Informed consent is crucial to ensure participants understand the nature of the study before agreeing to participate.
Methodological Limitations
- Different research methods (e.g., recall, recognition, re-learning) can produce varying results, making it difficult to draw definitive conclusions about memory processes.
- The accuracy of memory can be affected by factors such as the passage of time and the presence of misleading information.
Schema Theory
- Schemas (mental frameworks) can distort or enhance memory, leading to inaccuracies and biases.
- The influence of prior knowledge and expectations on memory can be both beneficial and detrimental.
Different Models of Memory (continued)
- Multi-store model (MSM) and working memory model (WMM) are criticized for being overly simplistic and lacking consideration of emotional factors and prior knowledge.
- Studies have shown that memory processes are more complex than these models initially account for.
Cultural and Individual Differences in Memory
- Cultural background influences memory encoding, storage, and retrieval processes.
- Individual differences in cognitive style and learning approaches play a part in how information is encoded and subsequently retrieved.
Conclusion
- Evaluating memory models and theories highlights the complexity and limitations of our understanding of memory processes.
- Consideration of various factors, including method limitations, ethical concerns, and individual differences, is crucial for accurate interpretation of research findings.
- Further research is required to address the ongoing gaps in understanding memory.
