Abstract

Abstract: In order to explore the workers' risk-taking behavior and reduce the occurrence of falling accidents, a high platform used for simulating working at height was built in the laboratory. Then the physiological indexes including skin temperature, EDA, respiration and pulse were collected by the software ErgoLAB. Finally, SPSS software was used for correlation analysis to find out changes of data before and after the risk-taking behavior and to clarify changed characteristics of these physiological parameters. The results show that when the risk-taking behavior occurs, subjects' skin conductivity level increases significantly, the change of heart rate rhythm accelerates observably with time, the dispersion degree of respiratory frequency decreases, and skin temperature rises slightly while its degree of deviation from the mean value decreases significantly, and that all the changes of physiological parameters are independent of gender.

Key words: risk-taking behavior, physiological parameters, electrodermal activity(EDA), height operation, heart rate rariobility(HRV)
