Behavioural responses. Each panel shows a different response measured from the participants’ behaviour, which reflects statistically significant differences ($p<0.05$) between information treatments, scenarios, or their interaction (Information treatments $\times$ Scenario). Confidence intervals for the estimates are shown between brackets. The participant’s activity was divided into four subtasks, namely familiarization with the virtual environment (a), approaching the crossing (b,c), waiting to cross (d), and crossing (e). The duration in seconds is shown on the y-axis for each subtask in panels (a–e), and for the whole task in panel (f). Panels (g,h) illustrate differences in uniformity of speed (measured as ${\sigma }_{\mathit{speed}}$) and the total walked distance within the VR environment. Panels (i–l) highlight differences in head movement. Specifically, we report the mean ($\mu$) and standard deviation ($\sigma$) of change in pitch (i.e., looking up or down, see panels i,j) and yaw (i.e., turning head left or right, see panels k) as well as the cumulative total angle change in direction of the three axes per second (panel l). When shown, scenarios are grouped on the X-axis, featuring the aggregated distribution as a coloured box plot in blue, magenta, and bright orange. Violin plots show distributions for each information treatment within the same scenario: mint for sequential and orange for parallel. They are complemented by corresponding box plots displaying median values and interquartile ranges. For further details on the statistical methods see “Statistical details”.
