6.  The arousal theory states that we tend to remember events with strong emotional impact more than events with weaker emotional impact.  Strong emotional experiences release neurotransmitters and hormones that strengthen memory.  Therefore, we remember events where we felt stressed, surprised, angry, excited, or scared more than events where nothing happened.  This forms flashbulb memories.  An example of a flashburb memory would be the terrorist attacks of 9/11.  Most people remember exactly where they were at the time the towers were struck because of the intensity of emotions when they heard the breaking news. I remember being home getting ready for work when I turned on the TV and saw the breaking news.  While watching the horrific images on TV, feelings of confusion, fear, and overwhelm took over me at the time and I wasn't sure what to do.  I knew people who worked in NYC.  I wasn't sure whether to reach out to them and find out if they were ok or stay put.
