Bottom-up Top-down It involves taking in raw sensory information from the environment and processing it without relying on prior knowledge or expectations Data or stimulus driven Uses elementary details of sensory input and gradually builds upto higher level perception and understanding It uses higher level cognitive processes such as expectations and prior knowledge to influence the interpretation of incoming stimuli Knowledge or concept driven Uses mental models to make sense of ambiguous or incomplete sensory inputs by inferring missing details
