Questions and Answers

What is memory?

An active system that allows people to retain information over time

What does the Information-Processing Model state?

The ability to retain information over time involves three processes: Encoding, Storage, and Retrieval

What is encoding?

The process of making mental representations of information so that it can be placed into our memories

What is storage in terms of memory?

The process of placing encoded information into relatively permanent mental storage for later recall Signup and view all the answers

Study Notes

Memory Concepts

Memory: An active system enabling retention of information over time.
Information-Processing Model: Describes memory functions in three stages: Encoding, Storage, and Retrieval.

Memory Processes

Encoding: Creation of mental representations for information, essential for memory formation.
Storage: Long-term retention of encoded info, enabling recall at a later time.
Retrieval: The act of accessing or recalling stored information.

Memory Models

Three-Stages Model: Divides memory into sensory, short-term, and long-term categories.
Sensory Memory: Brief retention of environmental stimuli in raw form; lasts from an instant to several seconds.
Short-term Memory: Temporarily holds a limited amount of information (average 7 items) for 2 to 30 seconds.
Long-term Memory: Capable of storing vast amounts of information for extended periods.

Types of Sensory Memory

Iconic Memory: Visual sensory memory that holds images for about a quarter of a second before fading.
Echoic Memory: Auditory sensory memory retaining sounds for 1 to 2 seconds.

Advanced Memory Concepts

Working Memory: Active processing system integrating sensory info with long-term memory retrieval.
Maintenance Rehearsal: Technique of repeating information to maintain it in short-term memory.
Interference: Occurs when new information disrupts existing short-term memories.

Memory Techniques

Chunking: Method of organizing information into larger units or "chunks" to aid memory.
Primacy Effect: Enhanced recall of first items in a list.
Recency Effect: Enhanced recall of last items in a list.
Serial Position Effect: Tendency to remember items from the beginning and end of a list better than those in the middle.

Types of Declarative Memory

Declarative Memory: Knowledge of facts and events; includes:
- Explicit Memory: Consciously accessible memory.
- Semantic Memory: Facts, concepts, and language knowledge.
- Episodic Memory: Personal experiences and specific events.

Types of Nondeclarative Memory

Procedural Memory: Skills and tasks (e.g., riding a bike) learned through practice.
Implicit Memory: Memories that are not consciously accessible.

Memory Disorders

Amnesia: Loss of memory which can be temporary or permanent; results from brain injury, stress, or drugs.
Automatic Encoding: Unconscious transfer of information into long-term memory.
Effortful Encoding: Active effort required to transfer information, often through rehearsal or associations.
