This text demonstrates how the dynamic interplay between human and animal research has led to significant advances in diverse areas of psychology. Students are shown the value of this research by leading experts, who describe the paradigmatic use of laboratory animal models for studying and redressing such societal problems as anxiety, stress, aggression, depression, drug abuse and dementia. Chapters describe studies that have advanced understanding of the aetiology and treatment of depression; behavioural techniques and medications to improve memory in patients with Alzheimer's disease or children with developmental disabilities; the importance of stress and nutrition in the development of hypertension; pharmacological, physical and psychosocial interventions that relieve pain and suffering and allow paraplegic patients to walk with assistance; and one of the most effective treatments for cocaine and other drug addictions. The work should be useful for teachers and students of psychology at many levels, from introductory to advanced, who would like to explore how research with laboratory animals has enhanced and continues to enrich psychology.
