People are able to see the movements on their bodies without light

According to a new cognitive science research that used computerized eye trackers, at least 50% of people are able to see the movement of their hands even in the absence of light. This investigation was led by Duje Tadin, a professor of brain and cognitive sciences at the University of Rochester. The first author of the study is Kevin Dieter, a post-doctoral fellow in psychology at Vanderbilt University. This study involved 129 individuals. The research was published in Psychological Science. “This research shows that our own movements transmit sensory signals that also can create real visual perceptions in the brain, even in the complete absence of optical input”, said Tadin. The final results of this study prove that the movements are rather automatically learnt by people who are able to see the movement of their hands in the absence of light. Lindsey Bronnenkant, a lab technician, in collaboration with David Knill, a professor of brain and cognitive sciences at Rochester were also involved in the study.
