In this study, decision heuristics used by individuals with different responsibility controls were investigated. In the research, 370 final grade university students studying at Erzincan University Faculty of Education were included. In order to collect data, Internally Controlled Responsibility-Externally Controlled Responsibility Scale of Özen and Gülaçti (2011), and Decision Heuristics Scale developed by Özen (2015) were used. Obtained data were investigated benefiting from Pearson Product-Moment Correlation and t-test. As result of the analyses, it was determined that the students generally had internally controlled responsibility, and they mostly used representative heuristic. When the correlation of decision heuristics with Internally Controlled Responsibility-Externally Controlled Responsibility was investigated, a low level negative relationship was found between representative heuristic and Internally Controlled Responsibility-Externally Controlled Responsibility. A low level positive relationship was found between availability and adjustment heuristics and Internally Controlled Responsibility-Externally Controlled Responsibility. In the research, moreover, it was also determined when the students who had internally controlled responsibility were compared with the ones who had externally controlled responsibility that the students with internally controlled responsibility significantly used more logical representative heuristic and less availability heuristic and anchoring heuristic.
