Learn: Memory - GCSE Psychology Edexcel 1PS0

Welcome!Today we'll explore Memory, a fascinating topic in psychology. Memory helps us store, process, and retrieve information, which is essential for learning and everyday life. Let's dive in!

What is Memory?Memory refers to the process of taking in information, storing it, and retrieving it when needed. It allows us to recall past experiences, make decisions, and learn new skills.

Stages of MemoryMemory involves three key stages: Input (taking in information), Processing (organising and storing information), and Output (retrieving information when needed). Think of it like a computer: input is typing data, processing is saving it, and output is retrieving the saved file.

Short-Term Memory (STM)Short-Term Memory holds information temporarily, usually for around 15-30 seconds. It has limited capacity (about 7 items) and requires attention and rehearsal to move information into long-term memory.

Long-Term Memory (LTM)Long-Term Memory stores information for extended periods, sometimes for a lifetime. It has a much larger capacity than STM and relies on encoding, such as associating new information with existing knowledge.

Bartlett's Theory of Reconstructive MemoryThis theory suggests that schemas (mental frameworks based on prior knowledge) influence how we remember things. Our memories are not exact copies but reconstructions influenced by expectations and experiences.

Multi-Store Model of MemoryThe Multi-Store Model, proposed by Atkinson and Shiffrin, explains how information flows through three memory stores: Sensory Register, Short-Term Memory, and Long-Term Memory. Information moves through attention and rehearsal.

AmnesiaRetrograde amnesia refers to difficulty recalling past memories before an event, while Anterograde amnesia involves difficulty forming new memories after an event. Both can result from brain injury or trauma.

Review Time!Great work! You've learned about the stages of memory, the Multi-Store Model, Bartlett's theory, and types of amnesia. Let's test your understanding with a few questions.
