Page 1: Introduction to Cognition and Memory Models
Unit 7 M31: Focuses on cognition and memory, detailing various models and stages.
Memory Storage: Discusses how memory is stored in the brain, setting the groundwork for further exploration.
Page 2: Discussion Prompts
Reflection Questions:
What is your earliest memory?
How old were you at the time?
What causes us to remember one event over another?
At what age does memory develop?
Page 3: Infantile Amnesia
Definition: The inability to recall autobiographical memories from early childhood.
Brain Development: The frontal lobes and hippocampus are still maturing, limiting personal memory storage.
Memory Onset: Most memories begin forming after the age of 2.5 years.
Page 4: The Phenomenon of Memory
Memory Defined: Memory is defined as the persistence of learning over time through the storage and retrieval of information.
Page 5: Models of Memory
Connectionism Theory:
Suggests that memories are products of interconnected neural networks.
Memories are formed from activation patterns within these networks.
Frequent use of a pathway strengthens memory.
Page 6: Information Processing Model
Key Components:
Encoding: The process of transforming information for storage.
Storage: Retaining encoded information over time.
Retrieval: Accessing stored information.
Process Type: Sequential but often involves simultaneous processing (parallel processing).
Page 7: Information Processing Breakdown
Encoding: Involves processing information into the memory system.
Storage: Retention of encoded information over time.
Retrieval: Getting information out of memory storage.
Processing Nature: In reality, many processes are done simultaneously rather than sequentially.
Page 8: How We Encode
Types of Processing:
Automatic Processing (Nondeclarative): Unconscious encoding of incidental information, like time and space.
Page 9: Effortful Processing
Definition: Requires focused attention and conscious effort. Can become automatic with practice.
Example: Reading in reverse order involves effortful processing.
Page 10: Atkinson & Shiffrin Memory Stages
Framework: Memory consists of three distinct stages: Sensory Memory, Short-Term Memory (STM), and Long-Term Memory (LTM).
Page 11: Sensory Memory
Description: The immediate recording of sensory information, lasting only momentarily.
Types of Sensory Memory:
Iconic Memory: Brief visual snapshots.
Echoic Memory: Brief traces of sound.
Semantic Memory: Encoding of meaning, such as word meanings.
Page 12: Short-Term Memory (STM)
Definition: Activated memory holding a few items briefly before being stored or forgotten, averaging 7±2 items.
Duration: Lasts about 30 seconds without rehearsal.
Rehearsal: Maintenance rehearsal allows longer retention of information.
Page 13: Clive Wearing Case Study
Insight: As a case of profound amnesia, emphasizes the importance of STM/working memory in daily functioning.
Page 14: Baddeley’s Model of Working Memory
Concept: Distinguishes between visual and auditory information processing in working memory.
Key Limitations: Speed of rehearsal constrains STM capacity.
Page 15: Working Memory Dynamics
Replaces STM: Recognizes different systems for processing various information types.
Operational Sequence: Involves encoding, rehearsal, and retrieval processes.
Page 16: Components of Working Memory
Central Executive: Coordinates focus and manages the flow of information between different memory systems.
Brief Retention: Holds auditory and visual information temporarily.
Page 17: Baddeley Model Overview
Focus: The central executive processes important information from sensory memory to working memory for further encoding.
Page 18: Long-Term Memory (LTM)
Definition: A relatively permanent and limitless storehouse of knowledge, skills, and experiences.
Types:
Explicit Memory (Declarative): Requires conscious thought; involves facts and events.
Implicit Memory (Nondeclarative): Involves skills and conditioned responses.
Page 19: Eidetic Memory and Implicit Memory
Eidetic Memory: Also known as photographic memory; extremely rare and often misunderstood.
Implicit Memory: Initially effortful but becomes automatic with practice over time.
Page 20: Factors Affecting Storage
Key Influences: Attention, prior knowledge, and memory decay.
Page 21: Levels of Processing
Shallow Processing: Involves basic encoding techniques like maintenance rehearsal; yields short-term retention.
Memory Duration: Shallow processing does not facilitate long-term memory storage.
Page 22: Levels of Shallow Processing
Structural Processing: Encodes physical qualities (e.g., appearance).
Phonemic Processing: Encodes sounds (e.g., verbal repetition).
Page 23: Levels of Deep Processing
Deep Processing: Involves semantic processing based on meaning for better recall.
Characteristics: Requires elaboration, distinctiveness, personalization, and application.
Page 24: Effortful Processing Techniques
Self-Reference Effect: Relating material to personal experiences enhances memory retention.
Page 25: Overlearning Principle
Definition: Continued practice beyond mastery to achieve automaticity in skills.
Significance: Important for exam preparation to solidify knowledge long-term.
Page 26: Additional Effortful Processing Strategies
Chunking: Grouping information into manageable units.
Mnemonics: Memory aids that enhance recall through associations.
Distributed Practice: Spacing study sessions improves long-term retention.
Page 27: Rehearsal Learning
Nature of Rehearsal: Involves elaborative rehearsal, enhancing memory through conscious repetition.
Historical Study: Ebbinghaus' work on nonsense syllables showcases rehearsal effectiveness.
Page 28: Ebbinghaus’ Learning Curve
Observations: Rehearsing improves retention, with rapid initial learning tapering off over time.
Page 29: Spacing Effect
Principle: Retention improves when information is learned over extended periods rather than crammed.
Page 30: Serial Position Effect
Definition: Better recall of first and last items on a list, poorer recall of middle items.
Memory Strategies: Shuffle items in practice to combat this bias.
Page 31: Repeated Self-Practice
Testing Effect: Practice through retrieval enhances long-term memory retention.
Page 32: Exam Preparation Tips
Resource: Offers practical strategies for effective study and memory retention.
Page 33: Effective Study Techniques
Understanding Material: Prioritize comprehension of new information over rote memorization.
Review Structure: Use incremental review sessions to enhance recall ability over time.
