title: Heart rate reactions to standard laboratory challenges and a naturalistic stressor.
abstract: Extreme high and low heart rate reactors were selected on the basis of responses to two laboratory stressors; a video game, and mental arithmetic. The heart rates of the same subjects were then recorded during a public speaking competition. Heart rate reactions to this more naturalistic stressor were generally in line with the laboratory-based designations.
