“…Whereas the majority of research has examined how negotiators fail to detect integrative solutions (e.g., De Dreu, Koole, & Steinel, 2000;Giebels, De Dreu, & Van de Vliert, 2000), studies have yet to systematically examine psychological processes that lead to the emergence of nonagreements on part of the negotiated issues. Note that in the majority of previous studies, authors either excluded cases with impasses from further analyses (e.g., De Dreu, Giebels, & Van de Vliert, 1998) or substituted impasses with corrected scores (e.g., compromise solution, Carnevale & Lawler, 1986; lowest negotiation outcome possible, Kimmel, Pruitt, Magenau, Konar-Goldband, & Carnevale, 1980). Although this approach may be effective to reduce the heterogeneity of variance arising from cases with impasses (e.g., Lewis & Fry, 1977;Ten Velden, Beersma, & De Dreu, 2007), valuable information on detrimental effects in negotiations is largely ignored.…”
