unity in psychology is the idea that the human mind and behaviour are coherent and consistent, and that they can be understood as a whole rather than as a collection of separate parts or processes. unity implies that there is a harmony and integration among the different aspects of psychological functioning, such as cognition, emotion, motivation, personality, and social interaction. unity also suggests that there is a continuity and stability of the self across time and situations, and that there is a correspondence between the self and reality.
