Fig. 4.

On the left is a toy example environment consisting of four situations. The first two columns correspond to the con-artist example from the Introduction, the third and fourth to the tennis example. On the right is an example toolbox, where cues are indicated by links to events and actions are indicated by links to the actions. The ecological rationality of this toolbox would be: $\frac{0+1+0+1}{4}=0.5$
