“…This is suggested in the studies of soldiers in war (Blake, 1978;Rachman, 1979), Holocaust survivors (Kahana et al, 1985), individuals present during a terrorist attack (Kleinman, 1989), siblings of disabled children (Hannah & Midlarsky, 2005;McHale & Gamble, 1989), and survivors of natural disasters (Kaniasty & Norris, 1995b). Moreover, individuals who suffer and depend on help encounter altruistic role models (e.g., during war: Raboteg-Š aric et al, 1994;in hospitals: Seagle et al, 2002), and the reciprocity norm of helping can explain high levels of mutual support in times of human-made and natural disasters (e.g., in concentration camps: Kahana et al, 1985;during natural disasters: Kaniasty & Norris, 1995b).…”
