Learn: Memory - GCSE Psychology Edexcel 1PS0

Welcome!Today we'll explore the fascinating topic of Memory from GCSE Psychology Edexcel 1PS0. You'll learn about how memory works, key models, and some important studies. Let’s get started!

What is Memory?Memory is the process of storing and retrieving information. It helps us remember things we've learned, events we've experienced, and information we need.Memory can be categorised into different types, such as short-term memory (STM) and long-term memory (LTM). Let’s learn more about each type!

Short-Term MemoryShort-Term Memory (STM) holds information for a short period of time, usually around 15-30 seconds. Its capacity is limited, typically about 7 items.We use STM for things like remembering a phone number before dialling it. Rehearsing the information can help move it to long-term memory.

Long-Term MemoryLong-Term Memory (LTM) stores information for a long time, even a lifetime. It has a much larger capacity compared to short-term memory.Examples include remembering how to ride a bike or recalling your first day at school years later.

Multi-Store ModelThe Multi-Store Model, proposed by Atkinson and Shiffrin (1968), explains how information moves through memory.It includes three stages: the sensory register, short-term memory, and long-term memory. Attention and rehearsal help information move from one stage to the next.

Bartlett’s Theory of Reconstructive MemoryBartlett’s Theory suggests that memory is active and reconstructive. We remember by using schemas, which are mental frameworks based on our experiences and culture.This means memories are influenced by what we already know, and sometimes details are added or left out to fit our expectations.

Review Time!Great work! You've learned about short-term memory, long-term memory, the Multi-Store Model, and Bartlett’s Theory of Reconstructive Memory. Let’s test your understanding with some review questions.
