In 1998 at a high school in Tennessee, a teacher complained of a pungent “gasoline-like” smell in her classroom. Soon after, she fell ill, reporting symptoms such as nausea, shortness of breath, dizziness and a headache. Almost immediately several students in her class started to experience similar symptoms and, before long, the rest of the school was stricken.
The building was evacuated as Fire fighters, ambulances and police arrived on the scene to tend to the sick. That evening the local emergency room admitted 80 students and 19 staff members; 38 were hospitalised overnight.
But what was the mysterious toxic gas that sparked the outbreak? Several extensive investigations by Government agencies found nothing. Blood tests showed no signs of any harmful compounds. Instead, according to Timothy Jones a local epidemiologist, the fear of being poisoned had spread, fuelling the symptoms experienced by everyone inside.
A report in the New England Journal of Medicine attributed the outbreak to a phenomenon known as ‘mass psychogenic illness’, which occurs when the fear of infection spreads just as virulently as the disease itself. The students and staff had decided that, based on the behaviour of those around them, there was a real threat they needed to be afraid of.
The ‘outbreak’ in Tennessee demonstrates that people can be scared – to the point of sickness – without there actually being any real threat present. However, it begs the obvious question, what makes us feel afraid?
What are you afraid of?
One person who could answer that question is Dr Emily Holmes, a clinical psychologist at Oxford University who uses a selection of film clips to scare people in the lab. Holmes’s research simulates the symptoms of Post Traumatic Stress Disorder (PTSD) by using moments from films scary enough to invoke flashbacks in the viewer later – a hallmark symptom of the disorder.
“There are a lot of individual differences in what scares people. We want our clips to be so fearful that they intrude into your consciousness when you don’t want them to. Often these are the clips where there’s a sudden realisation that someone’s going to be hurt or killed.
“This is basically in line with the definition of trauma in the DSM-IV [Diagnostic and Statistical Manual of psychiatric disorders].” According to the manual, trauma is ‘an event or events that involve actual or threatened death or serious injury, or a threat to the physical integrity of self or others’.
Using a film with these qualities ensured that the participants in her experiments would experience intrusive thoughts in the weeks following their viewing. “In typical experimental paradigms loud, surprising noises or electric shocks are used to get a physical fear reaction,” says Holmes. “But we’re trying to create a fear response that persists long after the viewing to simulate the effects of PTSD. The most effective clips were those that were very disturbing or showed some kind of terrible event that was impossible to stop.”

Dr Holmes isn’t alone in pursuing this line of research. At Wisconsin University, Professor Joanne Cantor has spent the last decade discovering how films can scare us long after we’ve left the cinema. In her research, Cantor says that three recurring themes pop up in the films that people said scared them the most: disturbing visual images, imminent threat and a lack of control.
“Your memory of the film makes an association to that feeling when you first saw the film,” says Cantor. “It’s similar to when we have a traumatic experience in our real lives. People wrote extensively about how they felt when they first saw the film, and how just thinking about it makes them feel the same way again.”
According to Cantor, it’s because the scariest films trigger a primitive part of the brain known as the amygdala. When we’re afraid, this area is shown to be highly active in fMRI scans. It sits in a ‘lower’ portion of the brain that would have developed early on in our evolutionary history to help us avoid becoming a snack for a sabre-toothed tiger, for example.
In scans, the amygdala’s activation coincides with the bodily response that we all associate with fear: increased heart-rate, blood pressure, sweating and alertness – otherwise known as the fight or flight response. When it perceives a threat, the amygdala triggers nervous responses and stimulates the production of hormones that affect the body. It’s also connected to the hippocampus, where we store our memories, so that it can remind us to be afraid when we encounter the same threat again.
