Abstract: This study provides a comparison between traditional fuzzy reasoning tools and a neuro-fuzzy system, both developed based on Mamdani approach in order to determine the influence of mood states on information processing during decision making. To begin, participants responded to questions on positive and negative prospects involving gains and losses on a health risk problem and explained the reasons for their decisions in writing. Three independent input variables, namely flexibility, originality and fluency were then derived from the participants' reasons for their choices. Four linguistic terms, such as low, medium, high and very high were used to represent each of the input variables. Using Mamdani's approach, both traditional fuzzy reasoning tool and a neuro-fuzzy system were designed for a three-input, one-output process. The neuro-fuzzy system was trained using a back-propagation algorithm. Compared to the traditional fuzzy reasoning tool, the neuro-fuzzy system could provide better results.
