A reflex in an unlearned, involuntary response that is not under personal control or choice – one of many that occur in both animals and humans A stimulus is defined as any object, event, or experience that causes a response Unconditioned stimulus (UCS) – automatic trigger to as response. You do not have to learn to respond to UCS – example: a feather tickling your nose causes you to sneeze. The feather tickling your nose is the unconditioned stimulus Unconditioned Response (UCR) – the unlearned response that occurs naturally in reaction to the unconditioned stimulus. The response occurs naturally and automatically. Example: gasping in pain after being stung by a bee Conditioned Stimulus (CS) A previously neutral stimulus that, after becoming associated with the unconditioned stimulus triggers a conditioned response. Example: the smell of food is an unconditioned stimulus and a feeling of hunger is the unconditioned response. Imagine that when you smelled your favorite food, you also heard a whistle Conditioned Response – the learned response to the previously neutral stimulus – learned reflexive response

    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.
