Fig 1.
Dining points (DPs) and all possible outcomes in the game.
In our study, there were six possible outcomes for each player.
Fig 2.
In this study, the task was divided into 4 blocks, 50 trials per block. Dining points would be set to zero at the end of each block.
Fig 3.
This figure shows the UIs employed in the study. The solid green line box is the level-1 UI, the blue dashed box is the level-2 UI, and the red line box is the level-3 UI.

Bonferroni’s post-hoc comparisons of the main effects of block and UI level on DPs.
The red box on the left of the figure shows the post-hoc comparison results of the block and the blue box on the right shows the post-hoc comparison results of the UI. (*p < 0.05, **p < 0.01, ***p < 0.001; the error bars denote 2 SDs).
Fig 5.
Bonferroni’s post-hoc comparisons of the main effects of block and UI level on situation awareness (SA) scores.
The red box on the left of the figure shows the post-hoc comparison results of the block and the blue box on the right shows the post-hoc comparison results of the UI. (*p < 0.05, **p < 0.01, ***p < 0.001; the error bars denote 2 SDs).

Correlation between SA scores and DPs.
There was a significant positive correlation between SAs and DPs with r = 0.5, indicating that the SA scores could reflect the participants' understanding of the task.
