Document Summary
Keep in mind: everything is experienced in our brain, the world you live in is constructed by you, context is important, change is important. Absolute threshold: minimum intensity of something that must occur before we experience that sensation. Difference threshold: just a noticeable difference between 2 stimuli for a person to detect that difference (1 teaspoons of chili powder vs. 2 teaspoons of chili powder : signal detection theory: Determining whether you notice a faint stimulus or not requires you to make a judgment based on ambiguous information. A person"s tendency to report detecting a signal in an ambiguous trail -> how much evidence you need to prove something they sensed: sensory adaptation. You stop responding to a particular stimuli because you become adapted to it: sensing chemicals: Stimuli for taste are chemical substances from food that dissolve in saliva taste receptors send signals to brain to experience the taste.
