48 adults completed three measures of cognitive styles, then completed three trials of a medium-fidelity simulation of a naval surveillance and threat assessment task called TITAN (i.e., “Team and Individual Threat Assessment Network”) that required participants to evaluate seven pieces of information for potential targets displayed in a radar space (e.g., direction, speed, bearing, etc.). After reviewing the information for each target, participants submitted their threat assessment and were provided feedback about the degree of actual threat for the target. Results showed a significant decrease in processing time across trials. None of the cognitive styles scores had a significant main effect on the mean time spent processing TITAN targets. In Study 2, 80 Canadian Forces personnel completed the three cognitive styles measures and worked in four-person teams on TANDEM II, a simulation similar to TITAN. Each team consisted of three subordinates who separately reviewed and integrated five pieces of complex information per target before forwarding their individual threat assessments to a team leader. The team leader then assessed the veridicality of the three assessments and integrated them into a final threat assessment for each of 42 targets in each of three sessions. Although none of the cognitive styles significantly predicted decision error or time, several interesting trends are of note. We discuss the results of these two studies in terms of their relevance with past
