What does a criminological psychologist actually do? Most people picture a modern-day Sherlock Holmes, helping the police to solve crimes, but the reality is far more interesting and complex. Psychology and Crime offers a fascinating introduction to criminological psychology, providing the reader with a comprehensive grounding in everything from cognitive forensics to police interviewing. Concise, informative and accessible, the book explores a range of theories to understand criminal behaviour, from the physiological to the social. It covers a range of contexts within the criminal justice system where psychology offers unique insights, including police investigation, the perspective of witnesses and victims, and courtroom proceedings. Thoroughly updated throughout to reflect developments in the field, and featuring new chapters covering cybercrime, terrorism and insights from neuroscience, this edition also includes a student-friendly 'Apply your learning' feature and case studies to bring the research to life. Accessibly written for all levels, and with concise coverage of both classic and contemporary psychological theory, this is the ideal book for anyone studying criminal or forensic psychology.

The COVID-19 pandemic and associated restrictions have had a negative impact on the mental health and wellbeing of many people worldwide, but this may have been particularly challenging for adolescents. However, there is a paucity of research examining the factors associated with good mental health during this time. The aim of the current study was to identify the protective factors amongst early adolescents in the UK that were associated with better mental health outcomes (internalising and externalising difficulties, and wellbeing) during the first national COVID-19 lockdown. Between September and December 2020, 290 11–14 year olds across North West England completed an online survey consisting of several measures pertaining to experiences of lockdown, and mental health and wellbeing. Hierarchical multiple regression was used to analyse the data. Results indicated that higher participant-rated lockdown experience (the extent to which it was fun, easy, and good) and higher levels of optimism were protective factors for all three outcomes of interest. Greater adherence to government guidance was a protective factor for internalising difficulties and wellbeing only, while family keyworker status was protective for externalising difficulties and wellbeing only. Community and school connection were protective factors for internalising difficulties; family connection and number of parents at home were protective factors for externalising difficulties; and peer support and family knowledge of COVID-19 were protective factors for wellbeing. In summary, the 'ordinary magic' of supportive relationships and positive experiences appear to be some of the key factors needed to maintain adolescents' mental health and wellbeing, and to help them overcome difficulties posed by the COVID-19 pandemic.
