Document Summary
What we do with that info, our reaction is perception. Psychophysics: ex: present a sound to someone and look at how someone is able to hear and how you interpret it. Absolute threshold: the point from non-detection to sudden detection of stimuli. Ex: the smallest change in sensation that we can notice. Weber"s: 1/30 of original weight will provoke detection in a person that it is heavier or lighter. Signal-detection theory: radar observation and looking to see if enemies are present. Subliminal perception: information presented visually or auditory presented so quickly that you are not aware of it but, your brain processes it. It is somewhat effective . ex: lipton iced tea experiment, experimental group shown subliminal iced tea messages and control group wasn"t and the experimental group was more thirsty for lipton iced tea. Sensory adaptation: the idea that we become used to things. Ex: 8c in july and people wear coats, 8c in.
