THE FOCUS OF STUDYThe attacks of September 11, 2001, were events thatcaught the United States unprepared.The researchers had started an EAR project on theprevious morning. The study was originally designed toshed light on aspects of everyday coping with personaltraumas.After the collapse of the World Trade Center towers inthe morning of September 11, the researchersreoriented the research plan to study what was thenthe beginning of a potential cultural upheaval.Additional participants were recruited from a databaseof people who had worn the EAR in the months prior.
RESEARCH QUESTIONS The purpose of the study was to track people’s natural social interactions during a time of national crisis. Participants wore the EAR continuously for the first 10 days after September 11. Pre-September 11 baseline data were available for all participants from either the monitoring that started the morning of September 10 or a previous EAR study. The ambient sounds captured by the EAR were coded and analyzed for the extent to which participants’ social interactions changed in the days following September 11. Also, the time course of talk related to the events of September 11 was mapped.
RESEARCH QUESTIONS Further, the researchers sought to identify psychologically healthy social-interaction patterns during times of crisis. To address this question, the researchers linked aspects of participants’ social interactions in the aftermath of September 11 to their subsequent psychological adjustment as measured by the experience of event-related intrusions and avoidance symptoms. Because of the small sample size, however, these analyses must be considered exploratory.
RESULTSOver the first 10 days after September 11, then, participantsdid not change their overall amount of interactions.Instead, they shifted from group and telephone conversationsto in-person dyadic encounters.Although the amount of talking about September 11 was highimmediately after the events and low 8 days later across alltypes of conversations, in dyadic encounters the eventscontinued to be discussed over the intervening weekend.
DISCUSSIONIn a set of exploratory analyses, this natural shift towarddyadic encounters tended to predict better subsequentpsychological adjustment in the form of fewer September11-related intrusions and avoidance behaviors.Considering the frequent finding that humans seek outothers under stress, it was surprising that there were nooverall increases in social interactions in the aftermath ofthe September 11 attacks.This raises the question of the extent to which the stress-affiliation link established in the laboratory holds up innaturalistic settings.
DISCUSSIONWhat might have driven participants to gradually shifttoward more in-person dyadic encounters, reducing theirgroup conversations and phone calls as time passed?From this perspective, it would have been informative totrack with whom people were actually interacting. Bothethical and methodological considerations thwarted thiskind of analysis.Researchers hope that future research will replicate thesefindings and further clarify the differential psychologicalrole of dyadic versus group interactions in coping withtrauma.
