How to Understand Memory in Psychology
By Dr Ayesha Khan · · 4 min read
Quick answer
Psychology explains memory through models that describe how information is encoded, stored and retrieved. Key models distinguish short-term and long-term memory and describe how information moves between them. For exams, learn the models, the studies that support and challenge them, and how to evaluate their strengths and weaknesses.
Memory as a process
Psychology treats memory as a process of encoding information, storing it, and retrieving it later. Breaking memory into these stages lets you analyse where and why remembering can succeed or fail.
Understanding memory as stages, rather than a single ability, is the framework that the models build on.
Short-term and long-term memory
A central distinction is between short-term memory, which holds a small amount of information briefly, and long-term memory, which holds far more for much longer. The models describe how information moves between them.
This distinction, and the evidence for it, is foundational. Much of the topic concerns how these stores work and interact.
The main models
Psychology offers competing models of memory, each describing its structure differently — some emphasising separate stores, others the depth at which information is processed. Learning the main models and what each claims is essential.
Knowing not just what each model says but how it differs from the others prepares you for the comparison and evaluation that exams require.
Supporting and challenging studies
Each model is supported by some studies and challenged by others. Learning the key studies, and what they show, gives you the evidence to evaluate the models rather than just describe them.
Case studies of memory, in particular, provide striking evidence. Knowing a few well lets you support or question the models convincingly.
Evaluating the models
Higher marks come from evaluating the models — their strengths, weaknesses, and the evidence for and against — not just describing them. No model explains everything, and the debates between them are where the analysis lives.
Practise weighing the models against the evidence, which is the skill the exam most rewards in this topic.
Applying it
Memory research connects to real issues — eyewitness testimony, revision techniques, memory disorders. Applying the models to these, where questions ask, demonstrates deeper understanding.
Linking the theory to a real application, using the models and evidence, is the kind of answer that reaches the top bands.
Frequently asked questions
How does psychology explain memory?+
As a process of encoding, storing and retrieving information. Breaking memory into these stages lets you analyse where and why remembering succeeds or fails, and it is the framework the models build on.
What's the difference between short-term and long-term memory?+
Short-term memory holds a small amount of information briefly; long-term memory holds far more for much longer. The models describe how information moves between them, and this distinction is foundational.
Why are there different models of memory?+
Because memory is complex and no single model explains everything — some emphasise separate stores, others the depth of processing. Learning what each claims and how they differ prepares you for evaluation.
Why do I need to know studies?+
Because each model is supported by some studies and challenged by others, and the studies give you the evidence to evaluate the models rather than just describe them, which is where higher marks are.
How do I get top marks on memory questions?+
Evaluate the models — their strengths, weaknesses, and the evidence for and against — rather than only describing them, and apply them to real issues like eyewitness testimony where questions ask.
