What are the main symptoms of depression I need to know for the exam?

For the exam, you need to know the behavioural (e.g., loss of energy, social withdrawal), emotional (e.g., low mood, worthlessness), and cognitive (e.g., poor concentration, negative thoughts) symptoms. The key is that symptoms must persist for at least two weeks and cause significant distress or impairment.

How do biological and psychological explanations of addiction differ?

Biological explanations focus on genetics and brain chemistry, such as the role of dopamine in reward pathways, making some people more vulnerable. Psychological explanations focus on learning, like operant conditioning where the pleasurable effects of a substance reinforce use, or classical conditioning where environmental cues trigger cravings.

What is the best treatment for depression: SSRIs or CBT?

Both are effective, but they work differently. SSRIs (e.g., Prozac) increase serotonin levels to improve mood, while CBT helps patients challenge negative thought patterns. Research shows CBT has longer-lasting effects and fewer side effects, but SSRIs can be quicker. Often a combination is most effective, especially for severe depression.

Do I need to know specific studies for this topic?

Yes, you should know key studies that evaluate treatments or explanations. For example, the study by Elkin et al. (1989) comparing CBT, IPT, and drug therapy for depression, or the study by NIDA on the effectiveness of nicotine replacement therapy. Use these to support your evaluation points.

How can I remember all the symptoms and treatments?

Create a table for each disorder: list symptoms under behavioural, emotional, and cognitive headings. For treatments, note the type (biological/psychological), how it works, and a strength and limitation. Use mnemonics like 'BEC' for symptoms (Behavioural, Emotional, Cognitive) and 'BPT' for treatments (Biological, Psychological, Therapy).

What does 'evaluate' mean in exam questions?

Evaluate means to judge the strengths and limitations of something, using evidence. For example, when evaluating a treatment, discuss its effectiveness (using research), side effects, cost, and patient preference. Always give a balanced argument and conclude with a justified judgment.

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.
