Atkinson and Shiffrin - Multi-store model of memory

Sensory Registor (memory)

Sensory register hold information about a perceived stimulus for a split second after the stimulus disappears, allowing a mental representation of it to remain in the memory briefly for further processing - Iconic, Echoic

Iconic memory (Sensory register)

• Visual Info

• Storage - 1/3 - ½ second

• Encoding - Exact replica

• Capacity - 4-7

Echoic memory (Sensory register)

• Auditory info

• Storage - 3-4s

• Encoding - Echo

• Capacity - Unlimited

Short term memory

Information that is attended to in the sensory register is passed to the STM
Duration - 3-4s
Encoding - Auditory
Capacity - 7 -/+ 2

Types of long term memory

Declarative - episodic, semantic
Procedural

Declarative memory (LTM)

Allows you to declare what it is you remember (explicit memory)

Episodic memory (Declarative - LTM)

Memory for past personal events (autobiographical memory)

Semantic memory (Declarative - LTM)

Memory of facts and information that enables us to construct meaning

Procedural memory (LTM)

Stores how you d things like riding a bike (implicit memory)

LTM E,C,D

Encoding - Semantic
Capacity - Unlimited
Duration - Relatively unlimited
