Expert testimony in human cognition are being used increasingly in legal situations. In this article, I describe how such testimony is formulated and provided. I illustrate using three criminal cases in which expert testimony in cognition was used. For each case I describe how combining the known physical facts surrounding the event in question with known psychological facts about the workings of human cognition can assist in providing for the trier of fact a theory of how the event unfolded.
