Basic Sensation Principles 1. Threshold : the minimum amount of information required for sensation a. Detection threshold a. Discrimination threshold a. Classical approach: absolute, objective threshold a. Signal detection approach: threshold can be affected by motivation, background noise 1. Adaptation : a decline in sensitivity that occurs when stimulation is prolonged and unchanging -As long as nothing is changing, your senses will lose sensitivity as they become bored Some examples: a. Olfactory adaptation - in a smelly room, you will progressively notice the stink less and less b. Visual afterimages - adaptation occurs most slowly - eyes have an involuntary muscle movement to change visual scene - hard to experience unless you try to focus hard on 1 thing c. Taste aftereffects - 1. Interaction : sensation/perception in one sensory system is affected by information from another sensory system - our experience in one sense is not completely affected by the one sense alone. Sense of taste can be affected by what we see i.e. the green ketchup, the purple ketchup

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
