Constriction

Definition

Shneidman's term for the psychological narrowing of options visible in suicidal communication: the world reduced to two possibilities (continue or stop), dichotomous thinking, and a collapsed time horizon. This psychological state has linguistic correlates that analysts use as markers.

Common questions

How does constriction show up linguistically in a note that analysts flag?+

Analysts look for absolute or binary phrasing such as only two options, no other way, or must end, alongside a narrowing of topic to a single unresolved conflict rather than the broader concerns typically present in a person's usual communication style, and a near-total absence of future-tense planning beyond the immediate act.

Can constriction alone confirm a note is genuine?+

No. Constriction is one of several psychological markers examiners weigh alongside linguistic consistency with the writer's known style, handwriting or typing habits, and the surrounding case circumstances. A single feature is not treated as a standalone test of authenticity.
