In the article titled “How Influential Are Mental Models on Interaction Performance? Exploring the Gap between Users’ and Designers’ Mental Models through a New Quantitative Method” [1], there was an error in the seventh paragraph of the subsection “3.7. Quantifying Mental Model Similarity” where the phrase “(see that )” should be removed.

Additionally, in the fifth paragraph of the subsection “4.1. The Influence of Information Structures on Mental Model Similarity” the phrase “than the three structure” should be corrected to “than the tree structure.”
