Document Summary

Sensation: the detection of physical energy by our sensory organs which is then relayed to the brain. Bottom-up processing: taking sensory information and then assembling and integrating it. Top-down processing: using models, ideas, and expectations to interpret sensory information. The cheating game allows us to quickly assume things. We might see the world in a way that is not accurate. 2. 1 can you tell something is going on. Absolute threshold: the minimum level of stimulus intensity needed to detect a stimulus half the time. Subliminal: below our threshold for being able to consciously detect a stimulus, but still registered by the sensory organ. Difference threshold refers to the minimum difference (in colour, temperature, etc) The difference between changes have to have some sort of consistency. 2. 3 is detection only a question of receptors. Signal detection theory aims to explain whether or not we detect a stimulus, particularly with background noise.
