The role of autonomy and social support in the relation between psychosocial safety climate and stress in health care workers

BACKGROUND: Health care workers are exposed to psychosocial work factors. Autonomy and social support are psychosocial work factors that are related to stress, and are argued to largely result from the psychosocial safety climate within organisations. This study aimed to assess to what extent the relation between psychosocial safety climate and...

The role of perspective effects and accelerations in perceived three-dimensional structure-from-motion

It has been suggested that perceived three-dimensional (3D) structure-from-motion can be accounted for by a 2-frame orthographic approximation of the flow field. This study investigated the extent to which higher order cues (perspective and acceleration) are used in addition to first-order flow. Participants matched the 3D dihedral angle of a...

A comparison of diferent ways to approximate time-to-line crossing (TLC) during car driving

Three experiments are presented in which the accuracy of different methods to approximate time-to-line crossing is assessed. In the first experiment TLC was computed, using a trigonometric method, during normal driving while the vehicle stayed in lane. The minima of TLC were compared with two approximations and it was found computing TLC as...
