According to new research conducted in a virtual reality environment, whether we feel scared or pleased in an environment and how we explore it is down to our combined perception of space and of our bodies. The study which was published in the journal Heliyon, suggests that the brain uses the interplay of these factors to control our emotional experience and exploration of an environment.

“Our hypothesis was that the emotional experience and the exploration of the environment are not simply triggered by environmental stimuli, but that the brain is regulating emotional experience and exploratory behavior based on the perception of one’s body and the spatial context in relation to each other,” explained lead author Dr. Martin Dobricki from the University of W├╝rzburg in Germany.

Dr. Dobricki and his colleagues tested their theory by seeing if the sensory input on the way people walk (their gait), and the sensory input on the spatial context they are within interdependently control their emotional experience and exploration of an environment. They put volunteers in a life-sized virtual forest glade and had them walk on a wood plank on the ground or elevated in the air.

The researchers found that a bouncy gait intensified people’s experience of the environment as negative and frightening when they were walking high off the ground as one might expect. Surprisingly, at ground level a bouncy gait gave people more positive emotions about the environment. This meant high up, a bouncy gait made people explore the environment more below the horizon, whereas on the ground it increased their exploration above the horizon.

As suggested by the findings, the information our sensory organs provide about an environment and the information they give about our gait influence each other in what the researchers call the “sensorimotor body-environment interaction.”

According to the researchers, adding a bouncy floor to a space, one used in a setup for treating fear of heights with exposure therapy, for example, could intensify people’s fear and therefore maximize the therapeutic effect of being exposed to height.

“Our research shows that we are not stimulus-response machines; our emotions and our behavior are both based on the interdependent perception of ourselves and the world,” said Dr. Dobricki.

“We hope that our findings will inspire other people to look at the body-environment interaction we have identified. For example, experiments like asking people emotion-inducing questions while they sit, walk or swim could result in many interesting and surprising findings and might lead to totally novel techniques for managing emotional response.”
