Fig. 5. Transfer of structural knowledge allows inference of unobserved links (Hexagonal graph).

Participants had to indicate which of two pictures is closer to a target picture. Participants that reached the second day of our task with the correct prior expectation over the structural forms performed significantly better in such task compared to participants with the wrong structural prior (left panel) (30 participants in each group). They were able to answer these questions significantly above chance even when there were links that were never observed, and they had to choose between two pictures with an identical number of observed links to the target (right panel). One-tailed t test. **p < 0.01, *p < 0.05. Error bar: SEM. Colorcode: Log₁₀(p-value).
