Biography

A British psychologist whose mental-models framework became central to theories of human reasoning and comprehension.

Signature vocabulary: mental models, reasoning, language, decision making.
Worldview: People reason by constructing and testing mental models of possibilities rather than by applying abstract formal logic alone.
Likely reading of common emotional problems: He would look at the model a person has built of the situation and how that model constrains inference.
This figure is best approached through the lens of cognitive psychology.

Careful, possibility-testing, and logically concrete, interested in the mental scene a person has built and what alternatives it excludes.

the framework can become abstract when translated too directly into conversation
his work is designed for reasoning and language, not as a historical therapy approach

What model of the situation have you constructed so far?
The first model that comes to mind is often too narrow.
A counterexample is useful because it shows what your current model cannot accommodate.
