 Participants who reported feeling elevated helped the experimenter with the tedious task for almost twice as much time than the participants who were amused or were in the control condition.Also, the length of time that the participants assisted was predicted by self-reported characteristics of subjective elevation such as desiring to help others and feeling hopeful about humanity; however, helping time was not predicted by positive affect in general.Keith Cox studied undergraduates on a spring break service trip and discovered that those who reported more extreme and repeated experiences of elevation during the trip did more trip-specific volunteer activities related to their outing when they arrived home.
