Philip Johnson-Laird, a psycholinguist, has written books and articles
about mental models and their relationship to language and reasoning.
In 2002, he wrote the following article about Peirce's existential
graphs as a promising direction for psychology and neuroscience:

Johnson-Laird, Philip N. (2002) Peirce, logic diagrams, and the
elementary operations of reasoning, Thinking and Reasoning 8:2, 69-95.
http://mentalmodels.princeton.edu/papers/2002peirce.pdf

Immediately after the abstract of that paper, he quotes CP 1.66:
Deduction is that mode of reasoning which examines the state of things
asserted in the premisses, forms a diagram of that state of things,
perceives in the parts of the diagram relations not explicitly mentioned
in the premisses, satisfies itself by mental experiments upon the
diagram that these relations would always subsist, or at least would
do so in a certain proportion of cases, and concludes their necessary,
or probable, truth.

In 2008, he published a book _How We Reason_, which has 24 references
to Peirce.  See below for the table of contents and some excerpts
from a review of the book.

Philip Johnson-Laird's How We Reason is a major contribution to the contemporary debate on the nature of reasoning. The author, who is widely known for his pioneering work in the experimental psychology of reasoning, in this book presents the theoretical framework of a life-long research project, which he labels a "model theory of mind"...

when we reason we represent the set of possible state of affairs of how the world could be. We do so by abstracting from the details of concrete pictures to form iconic representations, i.e. mental models whose architecture contains the common features of the different possible ways things can be arranged and combined. Johnson-Laird suggests us to think of these mental models as those an architect has in mind when he imagines the design of a future building...

Notwithstanding the efforts of constructing a logic of thought on the basis of purely formal notation, the diagrammatic representation enables us to represent the possible combinations at hand, and to clarify cases of vagueness. Logical notation comes later, when we express those models as propositions...
