This research extends recent efforts to differentiate communication in crisis negotiations (Taylor, 2002) by examining how negotiators' behavior differs across context. Data were 108 interaction episodes transcribed from 12 simulated crisis negotiations and coded at the level of thought units across 41 behavioral variables. Results of a smallest space analysis supported the hypothesized differentiation of communication behavior over 3 facets: overall orientation (Avoidance, Distributive, Integrative), motivational concern (Identity, Instrumental, Relational), and intensity (High to Low). This solution was used as a framework for identifying differences in behavior across simulated and actual negotiations. Analyses showed a systematic pattern of variations in behavior use, with simulated negotiations involving relatively more avoidance-relational and distributive-instrumental behavior than actual negotiations. Predictable differences were also observed in the purpose or function of behavior, with highly-intense behaviors showing greater uniformity in function across contexts compared to low-intensity behaviors.
