This chapter introduces the field of criminological psychology and explains how the study of crime brings together insights from psychology, sociology, law, and other disciplines to understand why people commit crime and how society responds. It begins by outlining how psychological theories – including psychodynamic, behavioural, cognitive, and personality approaches – help to explain criminal thought and behaviour. The definition of crime within a legal framework is explored, while outlining exceptions that affect criminal responsibility such as strict liability, infancy, insanity, and automatism. The chapter then traces how criminology developed from classical ideas of free will and deterrence: Beccaria, Bentham to positivist approaches that viewed criminality as biologically determined (Lombroso). It explores the shift towards social explanations of crime through the Chicago School’s theory of social disorganisation, which linked crime to poverty and the breakdown of community control. By comparing functionalist and conflict views of society, the chapter shows how moral and political values influence what is defined as crime. It concludes by defining criminological psychology as the integration of psychological theory with criminological research to understand and manage criminal behaviour.

This chapter provides a comprehensive overview of the nature, scope, and measurement of crime. It begins by framing crime as a universal and multifaceted phenomenon and examines its social, emotional, and cultural impacts, including its representation in the media and popular culture. The economic costs of crime to individuals and society are also considered. The chapter then addresses the recording and measurement of crime, reviewing official statistics, police data, and survey methods, while highlighting the limitations of these approaches and introducing the concept of the “dark figure” of unrecorded crime. Methodological issues in crime research are explored, focusing on offender self-report studies and victim surveys. Prominent victim surveys, including the Crime Survey for England and Wales (previously the British Crime Survey), are discussed in relation to design, sampling, coverage, and accuracy, illustrating their contributions to understanding crime trends and the challenges of capturing the full extent of criminal victimisation.

This chapter provides a comprehensive overview of psychological approaches to understanding criminal behaviour, tracing their historical development and conceptual evolution. It examines early psychobiological and psychodynamic perspectives, including Freud’s psychoanalytic theory and subsequent extensions by Aichhorn, Alexander, and Healy and Bronner, which link disturbances in early childhood relationships to delinquency. Attachment theory is considered, emphasising the role of caregiver-child bonds and their disruption in shaping later antisocial behaviour. The chapter then explores learning theories, from Pavlovian classical conditioning and Thorndike’s Law of Effect to Skinner’s operant principles and Bandura’s social learning theory, highlighting how behaviour is acquired, maintained, and influenced by reinforcement, punishment, and observational learning. Cognitive approaches are also discussed, including social information processing, moral development, rational choice, and cognitive distortions, which explain offenders’ decision-making and problem-solving patterns. The role of personality is examined through Eysenck’s model of extraversion, neuroticism, and psychoticism, emphasising the interaction of biological, social, and individual factors in shaping socialisation and antisocial tendencies. Twin, adoption, and longitudinal studies are reviewed to illustrate gene-environment interplay and intergenerational continuity. Overall, the chapter situates psychological explanations within broader sociological and criminological frameworks, stressing the complex, multi-factorial nature of criminal behaviour and the value of integrated theoretical perspectives.

This chapter focuses on the development of criminal behaviour across the lifespan, drawing on longitudinal research to examine how offending emerges, persists, and desists over time. It reviews findings from both prospective and retrospective studies that identify early childhood risk factors – such as family criminality, neglect, poor parenting, and behavioural difficulties – as predictors of later offending. Key evidence, particularly from the Cambridge Study in Delinquent Development, underscores how early behavioural problems combined with adverse family and social contexts contribute to persistent offending patterns. Two main developmental trajectories, highlighted in the work of Moffit, are distinguished: adolescence-limited (AL) offenders, whose delinquency is transient and socially driven, and life-course persistent (LCP) offenders, whose antisocial behaviour is stable, rooted in neuropsychological deficits, and reinforced by environmental adversity. This chapter also considers factors that promote desistance – such as positive parenting, stable relationships, and the assumption of adult roles – contrasting these with the ongoing challenges faced by persistent offenders, including poor health, economic disadvantage, and relational instability. Integrating findings from neuroimaging and biopsychosocial research, this chapter highlights the interaction between genetic, neurocognitive, and environmental influences, emphasising the importance of a multidisciplinary approach to understanding individual differences in criminal trajectories.

This chapter provides an overview of research and emerging theoretical perspectives on firesetting and arson, focusing on patterns, motivations, and offender characteristics across different ages and genders. It examines the predominance of males among both juvenile and adult firesetters, as well as their higher risk of injury or death from fires. Arson is classified according to frequency and timing – mass, spree, and serial – and linked to a range of motives, including revenge, financial gain, self-harm, and psychological gratification. The chapter also explores developmental and psychosocial factors, and examines the connections between firesetting and various mental disorders – such as personality disorders, psychosis, learning disabilities, and substance misuse. Finally, the chapter discusses key theoretical frameworks, including psychodynamic, learning, social learning, and multi-factorial models, highlighting both the psychological allure of fire and the significant personal and societal harms caused by arson.

This chapter provides a detailed examination of the psychology of violence, including sexual violence, exploring its prevalence, forms, and underlying causes across a range of contexts. It explores the distinction between aggression and violence, emphasising intent and harm, and considers gender differences, offender and victim characteristics, and the role of situational and social factors. The chapter examines forms of violence including homicide, assault, family violence, and sexual offences against children and adults, highlighting patterns of offending, legal frameworks, and the influence of family, social, and cultural factors. Case studies, historical examples, and international statistics illustrate variations in violent behaviour and societal responses. The second half of the chapter explores biological, psychological, and social explanations of violence and sexual violence; the research on attachment theory, personality, social learning, cognitive distortions, and developmental influences is examined. Overall, the chapter highlights the complexity of violence, emphasising the need to consider the interplay of individual, relational, situational, and cultural factors to understand, prevent, and respond effectively to violent crime.

This chapter provides a comprehensive overview of the interrelationships between mental disorder, personality disorder, and criminal behaviour, with a particular focus on legal responsibility, risk, and treatment. It traces the historical and legislative evolution of how mentally disordered offenders have been managed – from the M’Naghten Rules to modern Mental Health Acts – and analyses the legal concepts of insanity, diminished responsibility, and criminal culpability across jurisdictions. Empirical evidence is reviewed on the prevalence of mental illness, psychosis, schizophrenia, and intellectual disability among offenders, highlighting the influence of comorbidity, substance misuse, and social adversity on offending and recidivism. The discussion extends to the classification and management of personality disorders, particularly antisocial personality disorder and psychopathy, examining their diagnostic frameworks, clinical features, and implications for forensic practice. The development and subsequent decline of the Dangerous and Severe Personality Disorder (DSPD) initiative are also explored, illustrating the challenges of balancing public protection with therapeutic intervention. Overall, the chapter emphasises the complex biopsychosocial and legal dimensions underpinning the association between mental disorder and offending, underscoring the need for integrated approaches to assessment, management, and policy.

This chapter provides an exploration of the evolution, practice, and psychology of modern policing, bridging historical developments, contemporary challenges, and research. Tracing British policing from its early community-based roots to the formation of the modern police force and subsequent reforms, it examines how law enforcement has adapted to social, political, and technological change. Integrating psychological research, the chapter explores officer recruitment, training, stress management, and occupational functioning, highlighting the influence of personality, motivation, and organisational factors on performance and well-being. Key investigative processes – including evidence gathering, eyewitness reliability, suspect identification, confessions, and deception detection – are analysed through empirical studies and case examples, illustrating the complexities of criminal investigation. The chapter also examines offender profiling and crime linkage, emphasising both methodological innovations and ongoing debates about their scientific validity. Combining historical perspective, practical insights, and psychological theory, this chapter provides a comprehensive guide for anyone interested in understanding how psychological science supports the work of the police.

This chapter examines the role of psychology in the courtroom, highlighting how human behaviour, cognition, and emotion influence legal processes. It explores eyewitness memory, jury decision-making, and the work of psychologists as expert witnesses, illustrating the impact of scientific evidence on verdicts. This chapter also considers sentencing, explaining how judges apply guidelines while weighing culpability, harm, and mitigating or aggravating factors, and explores the psychological aspects of judicial decision-making. Finally, it addresses wrongful convictions, emphasising the profound personal and societal consequences of errors in the justice system. By combining empirical research, historical context, and real-life examples, the chapter offers a detailed understanding of how psychological insights inform fair and effective justice within court settings.

This chapter critically examines punishment, exploring its moral, utilitarian, and practical dimensions. It contrasts retributive justice, focused on proportional moral redress, with utilitarian goals of deterrence, rehabilitation, and public protection. Tracing the evolution of punitive practices from brutal historical sanctions to modern custodial systems, it evaluates the crime-reducing potential of imprisonment, probation, electronic monitoring, and extreme measures such as the death penalty. Drawing on international evidence, the chapter interrogates general and special deterrence, showing how fear of punishment often fails to prevent offending and highlighting the role of moral and social motivations in compliance with the law. Psychological and learning-theory perspectives reveal why delayed, inconsistent, or insufficient sanctions rarely change behaviour. The chapter also considers the human and societal costs of punishment, from prison overcrowding to solitary confinement, challenging assumptions about the effectiveness of harsher or longer sentences. It offers a rigorous, evidence-based analysis of how justice, public safety, and humane treatment intersect in modern criminal justice.

This chapter provides a thorough overview of offender treatment, linking research, theory, and practical application. It examines strategies to reduce offending, from psychotherapy, cognitive-behavioural, and family-based interventions to specialised programmes for sex offenders, violent offenders, and substance users. Drawing on decades of research and meta-analyses, it evaluates effectiveness, identifies the key principles of successful rehabilitation – risk, need, and responsivity – and highlights factors that influence programme delivery and completion. The chapter also explores restorative justice, including victim-offender mediation, conferencing, and restitution, critically reviewing international practice, conceptual uncertainties, and empirical outcomes. By examining assessment tools, evidence-based interventions, and emerging approaches such as the Good Lives Model, mindfulness, and multi-systemic programmes, the chapter offers practical guidance for reducing reoffending and promoting rehabilitation. Ultimately, it provides a roadmap for policymakers, practitioners, and researchers, emphasising the importance of evidence-based, ethical, and effective interventions in modern criminal justice systems.

This chapter provides a comprehensive exploration of crime prevention, integrating social, situational, and environmental approaches to reduce offending and enhance community safety. It examines the influence of everyday behaviours, substances, and media on criminal activity, considering alcohol, drugs, pornography, and violent media alongside legal, educational, and treatment-based interventions. Key practical strategies are analysed, including Neighbourhood Watch, street lighting, target hardening, situational measures, surveillance, and repeat victimisation prevention. Drawing on empirical research, international comparisons, and case studies, the chapter evaluates the effectiveness of community-led initiatives, technological innovations, and environmental modifications. At the same time, it critically considers potential challenges such as displacement, ethical dilemmas, civil liberties, and the emergence of vigilante activity. By combining theory, research evidence, and applied strategies, the chapter offers a nuanced framework for understanding, preventing, and mitigating crime.

This chapter explores the vital role of evidence in psychology and its application to crime prevention and the criminal justice system. It examines the collection, analysis, and interpretation of data, highlighting the challenges of implementing rigorous research in complex real-world settings, such as prisons. Using UK and international case studies, it considers the tension between research evidence, policy priorities, and political influence. A key focus is the prevalence of non-evidence-based practices, or “correctional quackery”, where anecdote, authority, and fads override research evidence. The chapter evaluates the social and financial costs of crime, demonstrating how evidence-based interventions – prison diversion programmes, therapeutic communities, electronic monitoring, and restorative justice schemes – can reduce reoffending and generate economic benefits. Overall, the chapter illustrates how connecting robust research with practice and policy improves outcomes and can ensure that public funds are used effectively.
