  • Why Research Studies Still Matter in Teaching Psychology

    One of the quiet revolutions in teaching IB Psychology is this: our students no longer need to memorise outlines of 200 or more studies, each with two strengths and two limitations. That’s worth celebrating. It makes our subject lighter, more engaging, and far more relevant. Students can now focus on developing critical thinking, connecting concepts, and applying their knowledge rather than playing flashcard games with endless lists of studies.

    But let’s not forget: research is the scientific foundation of psychology.

    Would you teach ethics in psychology without telling your students about Little Albert and the white rat, Zimbardo’s appalling Stanford Prison Study, or Milgram’s not-so-appalling obedience experiments? Of course not. These are the stories that not only illustrate concepts but also bring to life the ethical debates that shape our subject.

    Would we introduce social identity theory without Sherif’s Robbers Cave study? Could we possibly explain observational learning without Albert Bandura’s endlessly punched Bobo doll? And when we turn to methods, what better way to anchor quasi-experiments and neuroplasticity than Eleanor Maguire’s London taxi drivers, or to illuminate the case study method than Henri Molaison, whose memory loss is legendary?

    The point is simple: research gives psychology its credibility.

    Yes, assessment criteria don’t explicitly require studies by name. Students aren’t graded on whether they remember that it was 22 boys in Sherif’s camp or 72 children in Bandura’s playroom. But to teach any of the IB Psychology concepts with integrity, we must draw upon the research that produced them. Without robust studies and their conclusions, our discipline risks floating away into abstraction, detached from the science that grounds it.

    So let’s celebrate freedom from rote memorisation, but let’s also celebrate the research itself. Studies are not an add-on; they are the very evidence that makes psychology worth studying.

  • Moving from research studies to real-world examples

    One of the most noticeable shifts in the new course is the emphasis in assessment on examples rather than memorised research studies. In Paper 1, Section A, those short 10-minute questions are marked against just two descriptors:

    1. The response demonstrates detailed knowledge relevant to the question.
    2. The example is relevant and explained.

    Note that word — example — not research study. In fact, the only time assessment criteria explicitly require reference to a research study is when it’s mentioned in the question itself (Paper 2, Section B).

    Over the years, I’ve enjoyed teaching the finer details of Henri Molaison (Scoville & Milner), Baby Albert (Watson & Rayner), Milgram, Odden & Rochat, Caspi et al… These classic studies are fascinating and still worth knowing, but the new Guide is clear: it’s example, not studies.

    Research will always be a valid and robust part of a Psychology course.

    Students often memorise outlines of these studies and then regurgitate them in the exam. That’s not the same as demonstrating real knowledge and understanding.

    This isn’t to say we should stop teaching research studies — I certainly won’t. I’ll continue to speak lovingly of the Dunedin Study, the HM case, and several others. But students and I won’t be getting anxious about memorising the number of participants in the HM case study (eh hem, that’s a little psychology research joke there), or the nationality of Dunedin Study participants, or the socioeconomic status of Kahneman and Tversky’s samples. We can still use research studies — and we should — but students won’t have to memorise the details.

    The real focus is transfer of knowledge. Taking Social Identity Theory and applying it to a bullying case in a school or an international conflict. Using Social Learning Theory to describe how a public health campaign could reduce teenage alcohol consumption. Even if the example is fictional, applying the theory to a fresh, unseen situation shows depth of understanding far better than rattling off participant numbers and procedure details.

    This shift isn’t about discarding research — it’s about using it. The research is the foundation. But in assessment, it’s the bridge from theory to application that earns top marks. And that’s a far better reflection of what it means to understand psychology.

    Discuss the role of Social Identity Theory in explaining a conflict.

  • A New School Year – Wherever You Are

    Whether you’re in your very first year of teaching IBDP Psychology or your thirtieth, in some ways it doesn’t matter. You’re standing in front of a new set of students. Fresh faces, fresh questions, and—if we’re honest—fresh challenges.

    Same but different.

    Maybe you’re teaching in the same school you once sat in as a student yourself, or maybe you’re on the other side of the globe—Morocco, Mauritius, Oman, Albania. Again, that’s not really the point. Because teaching, at its heart, is about guiding and supporting your students, wherever you happen to be.

    Yes, I know… the year will kick off with a few staff meetings. Some will be useful. Others… well, let’s just say “less so.” If you find yourself in one of those, you could quietly plan a lesson or even play a quick game of chess from the back row. (Not that I’m encouraging mischief, of course.)

    Your first lessons aren’t about ploughing through the syllabus—they’re about setting the tone. Letting students (and their parents) know they’re in safe, well-prepared hands.

    You might kick off with an introduction to the experimental method—perhaps demonstrating the Stroop Effect to show how something as simple as reading a word can become surprisingly tricky when colour and meaning clash.

    Or you might spark a discussion about human behaviour:

    • Why are some people passionately in favour of immigration to the UK, while others are equally passionately opposed?
    • Why do some students show up every single day, while others are unfazed by missing lessons?
    • Why are some people shy while others brim with confidence?

    Or perhaps you want to open with ethical considerations—just a quick, engaging chat about Zimbardo’s prison study or Watson and Rayner’s famous “Little Albert” experiment. You could even take your students into the playground to observe younger children for prosocial behaviours—psychology in action from day one.

    Whatever you choose, choose something that excites you. That enthusiasm is contagious.

    And, you know, take very good care of yourself.

    So here’s to the start of your year—new students, new questions, new discoveries. Wherever you are in the world, whatever your teaching style, we’re wishing you all the very best.

  • Want to improve your students’ IB Diploma results?

    As DP Coordinators and teachers pore over this year’s IB Diploma results, now is the time to think not just about content delivery, but on how your students are learning. The key to improving your school’s performance probably isn’t more revision sessions, tougher mock exam marking, greater intensity with internal assessments or even more teacher training…, the key to success in school is much more likely to be a shift in student mindset, habits, and engagement.

    IB Diploma Psychology – Success at high school or college, written by a teacher with 30+ years of experience, offers exactly that: a practical, common-sense guide to helping students become more disciplined, proactive, and resilient—qualities that consistently lead to stronger academic outcomes in school and beyond.

    Unlike quick-fix test strategies, this book provides a blueprint for long-term success: attending every class, managing time effectively, building positive relationships with teachers, and understanding how learning actually works. It’s simple, clear, and designed to be implemented now—not in theory, but in everyday student life. This book is practical – and it’s written for and to your students.

    If you’re serious about lifting your students’ IB Diploma results in 2026 and beyond, make this book part of your school’s toolkit. It may be the most powerful change you make this year.

  • The Role of Culture in the Context of Human Development

    Here is a brand-new worksheet for the Human Development Context based on an article published yesterday on the BBC website about the hidden brain changes in six-year-olds. This resource helps HL students discuss the role of culture in human development as well as the Concepts of Bias, Perspective, and Responsibility.

    It’s ideal preparation for answering Paper 3, Question 4.

  • Adult neurogenesis: New evidence and its relevance to neurotransmission

    For decades, scientists debated whether adult human brains can generate new neurons, a process known as neurogenesis. While neurogenesis had been documented in animals, evidence in humans was inconsistent—until now. A July 2025 study (Dumitru et al., 2025) offers compelling proof that new neurons are produced in the adult human brain, with clear identification of the neural precursor cells responsible for this process.

    Researchers at the Karolinska Institute examined postmortem brain tissue from individuals aged 13 to 78. Using advanced RNA sequencing techniques, they identified molecular markers of immature neurons and precursor cells in most brains. These findings confirm that neurogenesis occurs throughout life, particularly in the hippocampus, a brain structure central to memory and learning—and a key site of neurotransmission.

    This discovery is relevant to the study of neurotransmission because new neurons contribute to brain plasticity, synaptic communication, and potentially the regulation of neurotransmitters. The hippocampus, rich in glutamate, GABA, and dopamine receptors, may rely on newly generated neurons for encoding new memories and emotional regulation.

    Interestingly, two adult brains showed unusually high levels of neurogenesis; one belonged to a person with epilepsy, raising questions about how increased or disrupted neurogenesis might affect brain activity. In animal studies, altered neurogenesis has been linked to depression and Alzheimer’s disease, suggesting a role for new neurons in mental health and neurological disorders.

    This study closes a major gap in our understanding of brain development and opens new avenues for researching how neurotransmission is influenced by ongoing neuron formation. It also raises key questions for psychology: How might neurogenesis affect behaviour? And can this process be enhanced to support mental health?

  • New: Motivation and Self-Determination Theory in the Learning and Cognition Context

    We’ve just created a new free worksheet designed to support DP Psychology (Higher Level) students exploring Motivation within the Cognition and Learning context. It’s particularly useful for developing responses to Paper 3, Question 4, which asks students to consider how the learning or cognitive process studied (in this case, motivation) relates to Learning and Cognition.

    The worksheet draws on an article by The Hechinger Report, which follows a student’s shift from disengagement to renewed motivation after enrolling in an innovative, student-led high school. Using this real-world example, students are introduced to key concepts from Self-Determination Theory (Deci & Ryan), including intrinsic and extrinsic motivation, and the psychological needs of autonomy, competence, and relatedness.

    The worksheet includes:

    • A clear 500-word text explaining Deci & Ryan’s Self-Determination Theory,
    • A vocabulary list (Psychology-specific terms)
    • Comprehension (AO1&2) and Critical thinking (AO3) questions

    This is a valuable, ready-to-use resource for helping students develop deeper conceptual understanding of motivation while also preparing them for Paper 3 Question 4.

  • Discuss the role of Culture in human behaviour (HL)

    In Psychology, culture means the values, beliefs, norms, behaviours, and practices shared by a group of people. Culture influences how we think, communicate, behave, and perceive the world around us.

    The Carpentered World Hypothesis states that exposure to straight lines and right angles in architecture affects visual perception (a cognitive process).

    The worksheet (below), summarises an article in The Guardian relating the role of Culture in Perception. The worksheet guides students to think about and discuss the role of Culture in the Learning and Cognition Context, linking to the Concept of Perspective.

  • The Dunedin longitudinal study, ageing, brain scans and dementia – a worksheet.

    The Dunedin longitudinal study, ageing, brain scans and dementia – a worksheet.

    News article:

    New Zealand scientists have helped develop an internationally groundbreaking tool that estimates a person’s risk of getting dementia and other age-related diseases.

    It uses a single MRI scan that can be done in mid-life and before someone is showing any signs of the conditions.

    Otago University scientists worked with Duke and Harvard universities in the United States and have published their findings in the prestigious medical journal Nature Aging this week.

    Data from Otago’s Dunedin Study – which has followed 1037 participants since they were born in 1972 and 1973 – has been critical in the work.

    That study looked at changes in blood pressure, glucose and cholesterol levels, tooth and gum health and other body functions over 20 years to see how quickly people were ageing.

    That data was then compared with an MRI taken when the study participants were 45 and a tool – an algorithm known as Dunedin PACNI – was developed that can look at anyone’s MRI and estimate how they might age.

    Dunedin Study director Professor Moana Theodore said study members who had higher or faster PACNI scores were more likely to have poorer health.

    “And also poorer physical functioning, things like walking and balance, and also poorer cognitive function, things like poorer memory even though they were, at that stage in their mid 40s,” she said.

    The new tool was then tested out on 50,000 brain scans from data on people aged 50-89 in other parts of the world.

    “In those studies of older people we were able to identify things like the development of chronic disease, so, an increased likelihood of heart attacks or strokes, an increased risk of being diagnosed with dementia over time and even an increased mortality,” she said.

    The study found those who were ageing faster had more shrinkage in the hippocampus region of the brain and performed worse on cognitive tests.

    Professor Theodore said the tool could help change outcomes for people.

    “If we can predict ageing, especially in mid-life…. then what we are able to do is prevent, possibly intervene earlier on to stop or slow down age related diseases like dementia for which there is currently no clear treatment,” she said

    She and her team were incredibly proud of the work – and she thanked the Dunedin Study members and their families for their 50 year contribution.

    “It’s wonderful to have a New Zealand study that is at the forefront of international research on ageing and how to support people to age positively and well and how to reduce age related diseases that cause people to have poorer quality of life later in life,” she said.

    DunedinPACNI will be freely available for scientists around the world to use to further their own work on ageing.
