A large body of research was conducted into events taking place during the terrorist attacks on 9/11, although it was not specifically geared toward finding gender differences. In one study researchers had participants answer questions to establish "consistent flashbulb memory," which consists of details about where the participants were at the time of the attacks, what they were doing, etc. In 2002 it was found that 48% of respondents fulfilled these requirements, and of those people 49% were women and 47% were men. They found that in 2003 45% of respondents surveyed met the criteria for having "consistent flashbulb memory." Of those 45%, women made up 46% of the group while men made up 44% (Conway, 2009). Women seemed more likely to have a more consistent memory for the event than men in this study. Temporal distance from the incident decreases the memory consistency.
