    Topic 3: Psychological problems – How would psychological problems affect you?

    EDEXCEL
    GCSE

    This topic explores the development of the individual, focusing on early brain development, cognitive development theories (Piaget), and learning theories (Dweck and Willingham) that explain how children grow and learn. It also examines the development of morality.

    Topic Overview

    This topic explores how psychological problems, such as depression and addiction, can affect an individual's thoughts, emotions, and behaviour. You will learn about the key characteristics of these disorders, including their symptoms and prevalence, as well as the different explanations for why they develop. Understanding these effects is crucial for appreciating the real-world impact of mental health issues and the importance of effective treatments.

    The topic is divided into two main areas: depression and addiction. For each, you will study the clinical characteristics (e.g., behavioural, emotional, and cognitive symptoms), two explanations (biological and psychological), and two treatments (biological and psychological). You will also evaluate the effectiveness of these treatments using research evidence. This knowledge helps you see how psychological problems are not just 'in the mind' but have measurable effects on daily functioning.

    This topic builds on earlier work about the brain and behaviour, and it connects to later topics on the self and social influence. By the end, you should be able to discuss how psychological problems affect individuals and society, and critically evaluate different approaches to treatment. This is a highly relevant topic for understanding modern mental health challenges.

    Key Concepts

    Core ideas you must understand for this topic

    • →Clinical characteristics: The specific symptoms used to diagnose a disorder, such as low mood and loss of interest for depression, or cravings and loss of control for addiction.
    • →Biological explanations: Genetic vulnerability, neurotransmitter imbalances (e.g., serotonin in depression), and dopamine's role in addiction.
    • →Psychological explanations: Cognitive factors (e.g., negative thought patterns in depression) and behavioural factors (e.g., operant conditioning in addiction).
    • →Treatments: Biological treatments (e.g., SSRIs for depression, nicotine replacement therapy for addiction) and psychological treatments (e.g., CBT for depression, aversion therapy for addiction).
    • →Evaluation: Using research evidence (e.g., studies on drug effectiveness or therapy outcomes) to judge the strengths and limitations of treatments.

    Examiner Tips

    Expert advice for maximising your marks

    • 💡Ensure you can define key terms like 'schemata' and 'equilibrium' clearly
    • 💡When evaluating theories, always provide both strengths and weaknesses
    • 💡Use the command words (e.g., 'describe', 'explain', 'evaluate') to structure your answers appropriately
    • 💡Be prepared to apply knowledge of these theories to new, unseen scenarios
    • 💡Remember that Paper 1 may draw on research methods knowledge in the context of these studies
    • 💡When evaluating treatments, always use specific research evidence (e.g., a study name or key finding) to support your points. For example, mention the effectiveness of CBT in reducing relapse rates for depression.
    • 💡For 8-mark 'discuss' questions, ensure you cover both sides: strengths and limitations of the explanation or treatment. Use a balanced structure with clear paragraphs.
    • 💡Link symptoms to explanations: e.g., explain how cognitive symptoms of depression (negative thinking) are addressed by CBT, or how cravings in addiction are linked to dopamine release.

    Common Mistakes

    Pitfalls to avoid in your exam answers

    • Confusing the stages of Piaget’s theory
    • Failing to distinguish between assimilation and accommodation
    • Misapplying Dweck’s mindset theory to real-world scenarios
    • Confusing the roles of the different brain regions in early development
    • Not linking the studies (Piaget/Inhelder, Gunderson) back to the theories they are meant to support
    • Misconception: Depression is just feeling sad. Correction: Depression involves persistent low mood, loss of interest, changes in sleep/appetite, and cognitive symptoms like poor concentration, lasting at least two weeks.
    • Misconception: Addiction is a choice or moral failing. Correction: Addiction is a chronic condition with biological (e.g., dopamine dysregulation) and psychological (e.g., reinforcement) components, making it difficult to quit without help.
    • Misconception: Biological treatments (e.g., drugs) are always better than psychological ones. Correction: Both have strengths and limitations; often a combination is most effective, and individual differences matter.
