Topic 7: Child psychology
Biological psychology focuses on the mechanisms within the body and how they affect human behaviour, with a specific emphasis on aggression. It explores the central nervous system, neurotransmitters, brain structure, evolution, and hormones as explanations for behaviour, while considering individual differences and developmental factors.
Topic Overview
Topic 7: Child psychology explores the fascinating journey from infancy to adolescence, focusing on how children develop cognitively, socially, and emotionally. This topic is central to understanding human behaviour, as early experiences shape lifelong outcomes. You'll study key theories like Piaget's stages of cognitive development, Bowlby's attachment theory, and Ainsworth's Strange Situation, alongside real-world applications in education, parenting, and social policy. Mastery of this topic is essential for A-Level success and provides a foundation for careers in psychology, teaching, or healthcare.
Child psychology is not just about memorising theories; it's about critically evaluating research methods and ethical considerations when studying children. You'll explore classic studies like Piaget's conservation tasks and Harlow's monkeys, while also considering modern debates about daycare, screen time, and resilience. This topic connects to broader psychological themes like nature vs. nurture and continuity vs. discontinuity, making it a rich area for essay questions and synoptic links.
Why does this matter? Understanding child psychology helps you interpret your own development and the behaviour of children around you. It also prepares you for exam questions that require application to scenarios, such as advising a parent on attachment or evaluating a school's approach to cognitive development. By the end of this topic, you'll be able to analyse research critically and apply theories to real-life contexts—skills that are highly valued in both exams and beyond.
Key Concepts
Core ideas you must understand for this topic
- →Piaget's theory of cognitive development: stages (sensorimotor, preoperational, concrete operational, formal operational) with key features like object permanence, egocentrism, and conservation.
- →Bowlby's attachment theory: innate need for attachment, critical period (2.5 years), monotropy, internal working model, and the continuity hypothesis.
- →Ainsworth's Strange Situation: secure, insecure-avoidant, insecure-resistant (ambivalent), and disorganised attachment types; cultural variations.
- →Vygotsky's sociocultural theory: zone of proximal development (ZPD) and scaffolding; role of language and social interaction in cognitive development.
- →Research methods in child psychology: longitudinal vs. cross-sectional designs, ethical issues (informed consent, protection from harm), and observational techniques.

Examiner Tips
Expert advice for maximising your marks
- 💡Ensure you can apply inferential statistical tests (Spearman's rho) to correlational data
- 💡Be prepared to discuss issues and debates (e.g., ethics, reductionism, nature-nurture) specifically within the context of biological psychology
- 💡Practice evaluating the validity and reliability of brain-scanning techniques
- 💡Ensure you can link biological theories to the specific contemporary studies listed in the specification
- 💡Be ready to discuss the implications of biological findings for society (e.g., social control, drug therapy)
- 💡Always use specific terminology from the specification, such as 'object permanence', 'internal working model', or 'zone of proximal development'. This shows the examiner you know the precise concepts.
- 💡For evaluation points, structure your paragraphs using PEEEL (Point, Evidence, Explanation, Evaluation, Link). For example, 'A strength of Piaget's theory is its practical application to education (Point), as seen in discovery learning (Evidence). This shows how theory can inform teaching (Explanation). However, it underestimates children's abilities (Evaluation), linking to the nature-nurture debate (Link).'
- 💡When answering application questions, explicitly link the scenario to the theory. For instance, if a child is upset when their mother leaves, refer to 'separation anxiety' and 'secure base' from attachment theory. Don't just describe the behaviour—explain it using psychological concepts.
Common Mistakes
Pitfalls to avoid in your exam answers
- Confusing correlation with causation in correlational research
- Failing to address the specific requirements of the practical investigation (e.g., Spearman's rho, descriptive statistics)
- Over-simplifying biological explanations (reductionism)
- Inadequate evaluation of brain-scanning techniques
- Misunderstanding the distinction between biological and psychodynamic explanations for aggression
- Misconception: Piaget believed children are passive learners. Correction: Piaget actually emphasised that children actively construct knowledge through interaction with their environment—he called them 'little scientists'.
- Misconception: The Strange Situation is a perfect measure of attachment. Correction: It has been criticised for cultural bias (e.g., Japanese infants show high rates of insecure-resistant attachment due to different caregiving norms) and may not capture all attachment types.
- Misconception: Daycare always damages attachment. Correction: Research (e.g., NICHD study) shows that high-quality daycare can have neutral or positive effects, especially when combined with sensitive parenting. The key is quality, not just attendance.
