IB Psychology 2.2.4 Cognitive Models Notes

Key Concepts

Cognitive models are theoretical frameworks that describe how mental processes work.

They break down complex processes into manageable components.

Models are not literal representations of the brain but are conceptual tools to understand how cognition operates.

Analogy

Think of a cognitive model as a flowchart for a computer system.
It shows how input, storage, and retrieval work, but it doesn't reveal the physical hardware inside the computer.

Multi-Store Memory Model (Atkinson & Shiffrin)

Proposed by Atkinson and Shiffrin (1968), this model describes memory as a system with three distinct stores: sensory memory, short-term memory, and long-term memory.

Information flows sequentially through these stores, with processes like attention and rehearsal determining whether it is retained or forgotten.

Key Components

Sensory Memory: Holds one piece of information for a brief period (less than a second).

Short-Term Memory (STM): Holds 7±2 pieces of information for about 15-30 seconds.

Long-Term Memory (LTM): Stores an unlimited amount of information indefinitely.

How It Works

Information enters sensory memory through the senses.
