In the new IB Psychology course (first exams 2027), the first two questions in Paper One are SAQs. These are 150-250 word answers that explain a topic and use an example. Previously, supporting examples always had to be studies. Now you have the choice – a study or a real world example. In this post, we’ll look at the same …
The Working Memory Model (Baddeley and Hitch, 1974)- A Simple Summary
At first glance the working memory model can be very complicated and overwhelming. This post will break it down into four simple steps so you can understand it. Step One: What is “working memory?” Step Two: What are the “slave systems?” Step Three: What is the “central executive?” Step Four: What is the “episodic buffer?” The Working Memory Model 1. …
Key study: Working memory and a dual task study on chess (Robbins et al. 1996)
Looking for a study that supports the working memory model? Here’s a good one. Working memory is the stuff we’re thinking about right now. The working memory model (WMM) was an elaboration of the multi-store model of memory (MSM) as it zooms in on the short-term store and explains how our short-term (working) memory actually works. If you can comprehend …
Digital vs. Print Reading: Which one’s better?
Are you trying to study with your laptop and smartphone? You might even argue that you need your phone to study because that’s how you read your textbook. You might even be reading this digitally if your school has shifted to digital texts in favour of old-fashioned textbooks. In this post, we’ll see what the research says about reading digitally …
Note taking: Is typing or handwriting better?
IB students are the iGen, so you probably can’t imagine working without a laptop. This begs the question – is it better to take notes by hand on paper or typing on a laptop? Let’s review the research. Let’s first look at Mueller and Oppenheimer’s now famous study “the pen is mightier than the keypad:” In this quasi-experiment, 67 students …
Example essay: Contrast two models of memory
Of the command terms for IB Psychology essays, “contrast” is the hardest to write. Here is an example essay that contrasts two models of memory. Please note – this essay is not written with the intention that you will memorize it. That is a highly inefficient way to study. It’s written so you can get ideas on how to structure a contrast …
Key Study: Schemas and Story Interpretations (Anderson et al., 1976)
“No two people read the same novel or watch the same movie.” This is one of my favourite sayings as an English teacher. It conveys the simple fact that our interpretations of stories are based on our personalities, our experiences, our biases, our schemas. While this might be common knowledge now, in the 1970s it was being slowly revealed through …
Key Study: The Office Schema Study (Brewer and Treyens, 1981)
Our life’s memories are filed away in our long-term memory and our mind categories these into clusters, which we call schema. These schema then affect how we process new information and remember old information. At least, these are the claims of schema theory. In this post we’ll look at how these claims are supported by a classic study. Because of …
Should you study with music?
I was 16 and studying for my big exams. I sat down at my desk and read a brochure my mum gave me. The first line said, “Turn off your music. Stop kidding yourself, you don’t study any better with it on!” I did and it helped. But were they right? As always in psychology, we have to ask ourselves …
Applications of the working memory model (Baddeley and Hitch, 1974)
Theories and models in psychology can be evaluated based on their empirical evidence and their validity in explaining and predicting human behaviour. But they can also be judged on their productiveness – the extent to which they’ve inspired and provoked further research and applications in various fields. In this post, we’ll look at the various contributions the WMM has made …
Memory Effects & The Working Memory Model
Want to improve your memory? The secret is to understand your working memory. In this post, we’ll review some factors that can reduce memory and then explain these using Baddeley and Hitch’s working memory model. The Articulatory Suppression Effect The articulatory suppression effect happens when memory decreases because researchers block (suppress) someone’s ability to rehearse (articulate) information they’re trying to remember. …
Four things you didn’t know about the multi-store model of memory
It’s in all the textbooks and every introduction to psychology course, but here are some things you didn’t know about Atkinson and Shiffrin’s multi-store model of memory. #1. There’s a store within the store The short-term store is where we temporarily hold information in our working memory. If it’s rehearsed enough it will transfer to the long-term store. But did …
Limitations of the multi-store model of memory (Atkinson and Shiffrin, 1968)
Atkinson and Shiffrin’s MSM is over 50 years old yet it’s still in every introduction to Psychology textbook and still influences modern psychologists. But it’s not without its critics. This post will examine some of their critiques. Because the MSM was so popular, it received a lot of criticism. But “…criticism could itself be viewed as a success, given the …
Key Study: Levels of Processing (Craik and Tulving, 1975)
Background Information The multi-store model of memory (MSM), while straightforward, seemingly common sense, and with plenty of empirical support, is not without its limitations. Do you really need to pay attention to, and rehearse, all sensory information in order for it to be transferred to your long-term memory? Take, for instance, experiences of traumatic or emotionally shocking events (e.g. Flashbulb …
The multi-store model of memory (Atkinson and Shiffrin, 1968)
50 years later and Atkinson and Shiffrin’s multi-store model of memory (aka the modal model) is still relevant today. This post summarizes the model in more detail than most introductory Psychology textbooks, which will give you the chance to distinguish your explanations from the rest. Background The multi-store model of memory (the MSM) is a product of the cognitive revolution …
Key Study: Cognitive appraisals and the stress response (Lazarus, 1963)
The most influential cognitive explanation of stress is based on “cognitive appraisals” – how we assess the relevance and potential harm of a stressor. The following study is one of many that supports this explanation. Stress is a complex phenomenon that involves biological, psychological and environmental factors. Richard Lazarus was a pre-eminent psychologist in the field of stress research. Along …
Key Study: Schema Theory & the Superwoman Self-schema
Schema theory is one of the most important theories in cognitive psychology, but it can also be one of the more difficult theories to understand. The best way, I’ve found, to understand schema theory is to look at as many real-life examples as possible. In this post, we’ll look at a fascinating example – the AfricanAmerican Superwoman self-schema. A schema …
Key Study: Gandhi and the Anchoring Effect Strack & Mussweiler, 1997
Are we always in control of our thoughts, or can they be influenced by invisible forces? The art of persuasion and subtle manipulation is a fascinating field of study in psychology. In this post, we’ll look at how people can manipulate our cognitive biases to influence our decision-making. One of the more interesting cognitive biases is the “anchoring effect.” The anchoring …

Essay Advice: Reconstructive Memory
Recently my class worked on a take-home essay with the question, “Discuss research memory, making referencing to one or more studies.” When reading and giving feedback on their essays, I found myself making similar comments – and the same ones I’ve been making for ten years. So here’s some advice that might help you avoid the same mistakes. Before we …
Key Study: Leading questions and the misinformation effect – ” the car crash study” (Loftus and Palmer, 1974)
Memory is a reconstructive process, which means memories are actively and consciously rebuilt when we are trying to remember certain things. Elizabeth Loftus, her colleagues and others studying this cognitive phenomenon have shown that during the reconstruction phase our memories can be distorted if we are given false information about the event – this is called the misinformation effect. Background Information …
Key Studies: “Weapon focus” and its effects on eye-witness memories (Loftus, 1987)
From decades of research we know that memory is not a passive cognitive process, but it is an active reconstructive one. As Elizabeth Loftus says, memory is not like a tape recorder that records things accurately and plays it back for us, but it’s more like a wikipedia page that anyone can go in and change. Loftus should know as …
fMRI: An important technological technique used to study the brain
The invention of functional magnetic resonance imaging (fMRI) has rapidly advanced our knowledge and understanding of the human brain. In the IB Psychology course, fMRIs are a good example of a “technique used to study the brain in relation to behaviour.” Background Information fMRIs are a modification of a regular MRI machine. Whereas MRIs simply show the structure of the …
