In recent years psychological research has become increasingly interdisciplinary. Psychologists work with biologists, medical researchers, physiologists, and biochemists on questions of a biological nature. They also work with sociologists, criminologists, anthropologists, and economists on questions relating to social behavior. Psychologists also work with mathematicians, computer scientists, philosophers, and linguists on questions involving the nature and origins of knowledge.
Current hot areas of biological research include human memory, cognitive processing, sensory systems such as vision or hearing, anxiety disorders, and various psychiatric and development disorders. In the area of sociology, researchers are studying body image, social and moral rules, social development across the lifespan, workplace violence, and gambling.
