| Abstract: | Recent investigations show that people's differential performance when solving reasoning tasks is due to differences not only at computational level, but also at the rational or intentional level. This study is within the framework of this context and it specifically analyses individual differences in hypothetic-deductive reasoning, taking into account the characteristics associated with the task itself (content and instructions) as well as the individuals' differential characteristics. Two hundred and seventy-six students from the University of Santiago de Compostela participated in this study. Several psychometric tests were administered and participants were requested to solve various reasoning tasks. The results obtained confirm that, in effect, the differences between competent and non-competent reasoners are observed at both the above-mentioned levels: cognitive skills and abilities (algorithmic level) and cognitive flexibility (intentional level). |
