• Resumen

  • El objetivo de este trabajo es el estudio de la formación en análisis y toma de decisiones sobre la forma de abordar una tarea de decisión entre alternativas multiatributivas. Se analizó la cantidad de información utilizada y las estrategias seguidas. Adicionalmente, se estudió si una determinada clave inicial provocaba un sesgo pre-decisional en los decisores. Se realizó un especial esfuerzo por controlar la importancia que los decisores asignan a los atributos, elaborando una tarea de «conflicto personalizado». Los resultados principales fueron: los sujetos con formación analizan significativamnte más información que los sujetos sin ella; atienden más a la alternativa finalmente elegida, pero lo hacen más como un proceso de consolidación que como un sesgo pre-decisional y utilizan estrategias compensatorias. La variable marcador no reflejó efectos significativos.
