Effects of september 11th terrorism stress on estimated duration

Abstract

Previous research has suggested that the duration of stressful video material is estimated to be longer than one containing less stressful material. The current study sought to examine what effects viewing news coverage of the September 11th 2001 terrorist attacks might have on estimated duration of exposure. 16 participants were recruited from Saint Joseph's College of Maine psychology courses and viewed two 3-min. video clips. One clip contained coverage of the 9-11 terrorist attacks; the other, a nonstressful control, was taken from a familiar segment of The Wizard of Oz. Participants estimated the length of the clip and rated stress experienced while viewing the clip. Analysis showed the September 11th footage was rated as more stressful and was estimated as longer than the control clip.
