Psychology is the scientific study of the mind and how it influences behaviour, from communication and memory to thought and emotion.
It is about understanding people and how this understanding can help us address and solve many of the problems in society. As a science psychology is dedicated to the study of human behaviour through observation, measurement, and testing, in order to form conclusions that are based on sound scientific methodology. Psychologists employ their knowledge and expertise in many areas of society, such as: Helping us prevent and overcome mental disorder, stress, and trauma; speeding up recovery from brain injury; improving performance both at school and in the workplace; assisting the police, courts, and prison services in the operation of their duties; and, analysing and improving athletic performance.
