Suicide ultimately requires a decision. In this article, I review a nu
mber of cognitive concepts-decision making, the development of a suici
de schemata, covert rehearsal, cognitive rigidity, and time perspectiv
e-and I propose a model suggesting that suicide can be understood as a
n essentially cognitive act affected by these elements. The model high
lights the importance of distortions of time perspective as a precurso
r for suicidal behavior. I propose this model as an additional set of
explanatory factors to those commonly in use, such as family and peer
estrangement and life events.
