摘要：The aim of this work is to study the effects of training in analysis and decision making on the way a multiattribute decision task is carried out. We analyzed the quantity of information subjects used and the strategies they followed. In addition, we studied whether a particular initial key or marker produced pre-decisional bias in decision makers. Furthermore, special effort was made to control the different importance assigned by decision makers to attributes, through the use of a «personalized conflict» task. The main results were: subjects with training analyze significantly more information than subjects without it; they devote more attention to the alternative eventually selected, but they do so more as a process of consolidation than as pre-decisional bias, and use compensatory strategies. Manipulation of the marker did not result in significant effects on the dependent variables.
