Abstract

Research on (TMT) illustrates that following mortality salience (MS) people defend their cultural world- views and bolster self-esteem to transcend . Recently, research additionally showed that MS increased self-reports of the number of children desired in Dutch men but not in Dutch women. We conducted three studies to further investigate the role of desire for oVspring in terror management. In Study 1, we conceptually replicated previous Wndings for Germany and found increased desire for oVspring fol- lowing MS in both men and women. Extending prior research Study 2 revealed that following MS not only was the accessibility of death- related thoughts increased, but also the accessibility of thoughts related to oVspring. Finally, Study 3 suggested that the MS eVect on ingroup bias was eliminated under conditions of oVspring salience. Relating these Wndings to TMT, anticipated or actual oVspring is dis- cussed as a buVer against existential . © 2006 Elsevier Inc. All rights reserved.
