Dreamworld ride’s fatal stress factor
AN expert in human behaviour told the Dreamworld inquest yesterday that staff operating the ride had to perform “one task every second” and it was inevitable their performance would suffer.
On the final day of the marathon inquest into the deaths of four people on the theme park’s Thunder River Rapids Ride, Professor of Cognitive Engineering and Human Psychology Penelope Sanderson said the stress of the 2016 incident also would have affected reaction times.
“There is a lot of work that people have to do in a given amount of time. If people are spending 80 per cent of their time carrying out tasks, their performance will suffer,” she said. “This (operating the Thunder River Rapids Ride) is more like 100 per cent. It would be difficult to sustain for a long period of time, raft after raft.”
Prof Sanderson said people could experience “cognitive tunnel vision” when under stress.
“The stress would have made it very difficult to work out what to do in the (malfunction) situation.”
