4-5 sleep cycles occur in a typical night's sleep. Emotions A class of subjective feelings elicited by stimuli that have high significance to an individual. Are valenced (?) Emotional Forecasting How accurate are we at predicting: 1. Future emotional states? 1. How long an emotion will last? Impact Bias The tendency to overestimate the duration of the emotional consequences of an event. o Causes of impact bias: Understimate the power of our emotional setpoint. Good at predicting valence & intensity of emotional reactions. Bad at predicting how LONG these emotional reactions will last. Emotional Homeostasis Adaption-Level Principle: you adapt to a current situation so that it becomes normal or the "neutral level". Changes from this neutral level produces an emotional response. Common-Sense Theory of Emotion Common sense suggests that the perception of a stimulus elicits the emotion which then causes bodily arousal. Sometimes we react physically before we're aware of what we're feeling. James-Lange Theory of Emotion Perception of a stimulus causes bodily arousal which leads to emotion.

    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.
