Memory Processes and Measurement

Memory Processes

• Encoding: Transforming sensory information into a mental representation. Think of it like converting raw data into a language your brain understands.
• Storage: Keeping the encoded information. This is like storing the converted data safely for later use.
• Retrieval: Accessing and using the stored information. This is like retrieving the stored data when you need it.

Measuring Memory

• Recall tasks: Re-producing information from memory, like listing all the items you need from the grocery store.
• Recognition tasks: Identifying information as previously encountered, like picking out your favorite song from a list.

Explicit vs. Implicit Memory

• Explicit memory: Consciously remembering past experiences. Think of remembering a special birthday party.
• Implicit memory: Unconsciously using past experiences, like knowing how to ride a bicycle without consciously thinking about it.

Traditional Model of Memory

• Sensory store: Very short-term memory that holds sensory information briefly, like the faint echo of a sound.
• Short-term store: Limited capacity, short-term memory for actively accessed information, like remembering a phone number just long enough to dial it.
• Long-term store: Vast capacity, long-term memory for stored information, like remembering your childhood memories.

Levels-of-Processing Model

• Deeper processing (semantic level) leads to better recall than shallow processing (visual level). Think of trying to remember a word based on its meaning versus just its appearance.

Working Memory Model

• A dynamic system that holds and processes actively accessed information. Imagine a mental workspace where you juggle different thoughts and tasks.
• Central executive: Manages attention and controls the processing of information. Like the project manager of your mental workspace.
• Visuospatial sketchpad: Holds and manipulates visual and spatial information. Imagine a mental whiteboard for visual images and locations.
• Phonological loop: Holds and rehearses verbal information. Like a mental tape recorder for sounds and words.
• Episodic buffer: Integrates information from the other components. Like the coordinator that puts everything together for a cohesive experience.

Multiple Memory Systems

• Semantic memory: General knowledge about the world like facts, concepts, and language.
• Episodic memory: Personal experiences. Think of remembering a specific event like your first day of school.

Connectionist Model

• Views memory as a network of interconnected nodes. Imagine a vast web of linked ideas and concepts. Activating one node spreads activation to other related nodes, explaining phenomena like priming and associations.

Exceptional Memory

• Mnemonists demonstrate extraordinary memory abilities. This exceptional ability often comes from using specific strategies and techniques.

Memory Disorders

• Amnesia: Loss of memory caused by brain damage or other factors, impacting the ability to access past experiences.
• Alzheimer's disease: A progressive degeneration of brain tissue leading to memory loss and other cognitive impairments.
