Question

alone in your house, you hear a noise in the middle of the night. your heart starts to pound, and you jump out of bed trembling. if an emotional response is made up of physiological arousal, expressive behavior, and conscious experience, which critical component is missing from your description of the event? you feel fear. your eyes dilate. your breathing increases. you hide under the covers.

Explanation:

An emotional response has three components: physiological arousal (e.g., heart pounding), expressive behavior (e.g., jumping out of bed trembling), and conscious experience (how you feel emotionally). "Your eyes dilate" and "Your breathing increases" are physiological arousal. "You hide under the covers" is expressive behavior. "You feel fear" is the conscious experience which is missing from the initial description (only physiological arousal - heart pounds and expressive behavior - jump out trembling were mentioned).

Answer:

You feel fear.
