IB DP Psychology — Cognitive Approach | SL & HL | Paper 1 & Paper 2
🎯 Learning Intentions By the end of this note, you will be able to:
- Define cognitive distortions, the cognitive triad, and schema theory using IB-aligned terminology.
- Explain how Beck's Cognitive Model accounts for the development and maintenance of depression and anxiety.
- Describe the role of automatic negative thoughts and maladaptive schemas in psychological distress.
- Evaluate research evidence for cognitive models of mental health using supporting and opposing studies in ACAS format.
- Apply cognitive model concepts to a real-world case study from the cognitive perspective.
- Discuss the extent to which cognitive models provide a complete explanation of mental health disorders.
- Analyse cognitive models using relevant concept areas: Bias, Causality, Perspective, and Responsibility.
Introduction & Context
Imagine you submit an assignment and receive a grade lower than you expected. One student reads the mark and thinks, "I need to study differently next time." Another reads the exact same mark and thinks, "I'm stupid. I always fail. Nothing I do will ever be good enough." Both students received identical feedback, yet their emotional responses are entirely different. The first feels motivated; the second feels hopeless. What explains this difference?
The answer, according to cognitive psychologists, lies not in the event itself but in how the mind interprets it. The way we think — the patterns, assumptions, and mental shortcuts we apply to everyday experiences — shapes how we feel and behave. When these thinking patterns become systematically distorted or negatively biased, they can contribute to psychological distress. This is the central claim of cognitive models of mental health, and it forms the foundation of one of the most influential frameworks in clinical psychology.
Cognitive models emerged in the 1960s and 1970s as a direct challenge to the then-dominant behavioural view that psychological problems were purely the result of learned responses. Psychiatrist Aaron Beck, working with depressed patients, noticed something striking: his patients were not simply sad — they were engaged in a continuous stream of negative, self-defeating thoughts that they rarely questioned. This observation led Beck to develop a systematic theory of how thought patterns drive emotional disorders.
🔍 Analogy — The Tinted Glasses Imagine wearing a pair of glasses with dark grey lenses. Everything you see — a sunny park, a smiling friend, a compliment — appears dim and colourless. The world has not changed; only the filter through which you see it has. Beck's cognitive model suggests that depression and anxiety work in a similar way: maladaptive schemas and cognitive distortions act like tinted lenses, colouring every experience with negativity. The goal of cognitive therapy is, in essence, to help the person remove the glasses — or at least become aware they are wearing them.
Core Concepts
To understand how cognitive models explain mental health, we need to start at the foundation: the idea that the mind organises experience through mental frameworks. From early childhood, we build up internal representations of ourselves, others, and the world based on our experiences. These frameworks guide how we interpret new
