Explain each of the five theories of emotion (James-Lange, Cannon-Bard, Schachter-Singer two-factor theory, Zajonc and LeDoux, and Lazarus) discussed in the text.

The James-Lang theory states that our experiences of emotion is our awareness of our physiological responses to emotion-arousing stimuli, meaning that your body does certain thing which is then followed by an emotion. For example, your heart racing, and body shaking would be followed by a sudden rush of fear. 

The Cannon-Bard theory states that an emotion arousing stimulus simultaneously triggers a physiological response and the subjective experience of an emotion. Disagreeing with the James-Lang theory, the Cannon-Bard suggests that the feeling of fear does not cause your heart rate to increase but your heart rate increasing, does not evoke a feeling of fear, rather, these are both separate occurrences that happen simultaneously.

The two-factor theory states that to experience emotion, you must be physically aroused and cognitively label the arousal. This means that in order to feel an emotion you have to be consciously aware of the stimuli provoking and causing the emotion. 

The Zajonc, LeDoux, and Lazarus theory states that some emotions can occur instantly with out conscious appraisal.

Explanation:

I just wrote this i hope it helps :)

light-year  

the distance that light travels in a vacuum in one year, equal to about 9.46 trillion km (5.88 trillion mi). light-years are used in measuring interstellar and intergalactic distances.  

parsec  

a unit of distance used in astronomy, equal to about 3.25 light years (3.08 × 1016 meters).  

parallax  

the apparent angular displacement of a celestial body due to its being observed from the surface instead of from the center of the earth (diurnal parallax or geocentric parallax) or due to its being observed from the earth instead of from the sun (annual parallax or heliocentric parallax)  

absolute magnitude  

the magnitude (brightness) of a celestial object as it would be seen at a standard distance of 10 parsecs.  

apparent magnitude  

the magnitude of a celestial object as it is actually measured from the earth.  

redshift  

an increase in the wavelength of radiation emitted by a celestial body as a consequence of the doppler effect.  

the great thing about your imagination is that it doesn't have to make sense! if i were you i would be stuck in space, no communication with earth travelling around and around, you can only guess how long its been since your communication broke down. you land on an undiscovered planet, you do a scientific investigation examining the elements and conditions. you come across alien lifeforms.  

best of luck!
