Understanding the Mysteries of Human Behavior

Title: Understanding the Mysteries of Human Behavior

  1. Why do your feelings get hurt? Like physical injury, a loss of social connection compromises your well-being. The brain areas involved in hurt feelings from rejection overlap with the areas involved in the experience of physical pain. Neuroscientists believe that the social pain system was built on top of the older system that mediates physical pain.
  2. Why do you sometimes forget things? One explanation for forgetfulness holds that a memory trace in your brain has deteriorated over time. In fact, the brain appears designed to allow disused memories to become less accessible so that you’re not overwhelmed with memories that are unimportant or that interfere with the acquisition of new information.
  3. Why do you fall in love? Research suggests that romantic love has three components—intimacy, passion, and commitment. Neuroscientists studying the biochemical bases of love have discovered that adrenalin, dopamine, and other chemicals are responsible for physical attraction, the desire for closeness, energetic feelings, and other symptoms of being in love.
  4. Why do you blush? Many people think of blushing as a social signal that communicates a nonverbal apology for breaking some social rule. But why do we sometimes blush when we are complimented or praised? Research suggests that blushing is analogous to appeasement displays in other animals. Humans blush when we receive unwanted social attention—negative or positive.
  5. Of course, not all of the mysteries of human behavior have been completely solved.
