Psychologists explore concepts such as perception,  cognition,  attention,  emotion,  phenomenology,  motivation,  brain functioning,   personality,behavior, and interpersonal relationships. Psychologists of diverse stripes also consider the unconscious mind. Psychologists employ empirical methods to infer  causal  and  correlational  relationships between psychosocial variables. In addition, or in opposition, to employing  empirical anddeductive methods, some—especially clinical and counseling psychologists—at times rely upon  symbolic interpretation and other inductivetechniques. Psychology has been described as a "hub science",  with psychological findings linking to research and perspectives from the social sciences, natural sciences, medicine, and the humanities, such as philosophy.
