Lab 4 Review: Short-Term Memory

These flashcards cover key concepts related to short-term memory, the Atkinson-Shiffrin model, and their characteristics including capacity and duration.

Atkinson-Shiffrin Model

A model of memory that describes three main stores: sensory memory, short-term memory, and long-term memory.

Control Processes

Processes such as attention, encoding, rehearsal, and retrieval that move information between memory stores.

Short-Term Memory (STM)

A memory system that holds information currently in use, requiring active mental effort to maintain it.

Capacity of Short-Term Memory

According to Miller (1956), STM can typically hold about 7 plus or minus 2 items.

Digit Span Task

A method for measuring STM capacity where participants recall sequences of numbers presented to them.

Decay Theory

The theory that information in short-term memory fades over time if not actively rehearsed.

Interference Theory

Keppel and Underwood's theory that suggests interference from other information can impede recall from short-term memory.

Working Memory

An extension of short-term memory that emphasizes its dynamic nature and active processing of information.

Duration of Short-Term Memory

Research shows retention of information decreases significantly over 18 seconds without rehearsal.
