Psychology is the science of human behavior, the mind, and mental
processes in humans and animals as they interact with each other and the
environment. As a practice, psychologists focus on diagnosing, assessing,
and delivering preventive and therapeutic services directly to individuals.
In academic settings, psychology has grown to be one of the most widely chosen
areas of undergraduate study. Areas of specialty include personality,
group interaction, physiology and behavior, intelligence and memory, emotion,
sensation and perception, genetics, and states of consciousness and the
abnormal development and treatment of these processes.
