Study Notes
Levels of Processing Theory
- The more deeply something is processed, the more likely it is to be remembered.
Atkinson and Shiffrin Model
- This theory suggests that information is processed through multiple stages: sensory register, short-term memory (STM) and long-term memory (LTM).
Sensory Register
- Stores raw sensory data for a brief period (1-3 seconds).
- Holds information that is encoded in the same form as the real world.
- The process of recognizing information involves focusing on key features and associating them with stored knowledge.
- Information in sensory register is selectively focused on based on what is already known and stored in long-term memory.
Short-Term Memory
- Holds 7 +/- 2 chunks of information (limited capacity).
- Information is maintained for 20 to 30 seconds.
- Contains information received from Sensory Register , and information retrieved from LTM.
- Rehearsal is a key process:
- Maintenance rehearsal (repetition) doesn't lead to long-term storage.
- Elaborative rehearsal (connecting new information with existing knowledge) does promotes long-term storage.
- Organization (chunking) is essential for remembering information.
- Meaningfulness (linking information to existing knowledge) enhances memory.
- Visual imagery encoding helps to recall information.
- Dual coding theory suggests visual and verbal representations enhance memory.
Long-Term Memory
- Unlimited capacity.
- Duration is permanent.
- Stores information in the form of schemas, which are interconnected networks of ideas.
How information is organized in long-term memory
- Schemas are utilized to assimilate new knowledge.
Memory Retention
- Most studies suggest that learning loss is less than 20%, with the majority of forgetting occurring in the first 4 weeks after learning.
- More unfamiliar subjects, and less relevant prior knowledge leads to greater forgetting.
- Higher levels of learning, active participation, and understanding the material significantly reduce forgetting.
Functional Memory Processes
- Focuses on how memory works in relation to real-life tasks.
Working Memory Model Components
- Working memory is the active processing system.
Assumptions of Working Memory:
- There are two separate information processing channels: auditory and visual.
- Each channel has a limited capacity for processing information.
- Meaningful learning requires engaging both channels: visual and auditory.
Multiple Components Model of Working Memory
- Working memory is a complex system with multiple components, including:
- Central executive
- Visuo-spatial sketchpad
- Phonological loop
- Episodic buffer
Central Executive
- Controls and manages working memory.
- Directs attention to relevant information.
- Suppresses irrelevant information.
- Integrates information from different sources.
- Coordinates cognitive processes.
- Supervises information processing.
Phonological Loop
- Processes and stores auditory information.
- Rehearses verbal information to prevent decay.
Visuo-spatial Sketchpad
- Processes and stores visual and spatial information.
- Used for mental imagery and spatial reasoning.
- Composed of two subsystems:
- Visual subsystem
- Spatial subsystem
Episodic Buffer
- Integrates different types of information.
- Connects with long-term memory.
Research on Memory Retrieval
- A model for memory retrieval based on neural networks (Hopfield networks) shows that connections between memories are determined by how similar their representations are in Long Term Memory.
- Certain network properties, like oscillating feedback inhibition and noise, influence the speed and ease of memory retrieval.
- The theory shows that memories with larger representations in the network are retrieved faster, which suggests a potential bottleneck in our memory retrieval capabilities.
How to Protect Your Memory
- Reduce stress.
- Avoid drug use and alcohol consumption.
- Limit exposure to neurotoxins.
- Engage in regular exercise.
- Stimulate your brain with mental activities.
- Maintain a strong sense of self-efficacy.
How to Improve Memory
- Write things down.
- Attach meaning to information.
- Repeat and rehearse information.
- Categorize information into groups.
