At the undergraduate level, this department offers a major in either psychology or neuroscience. Psychology is a broad discipline that seeks to understand human cognition, emotion, and behavior. It is also an applied field that is concerned with testing perception, psychopathology, inheritance of complex behavioral traits, mental health, memory, and social factors that influence behavior. Neuroscience is the study of the mechanisms of nervous system—the brain, the spinal cord, and networks of sensory nerve cells, or neurons.
