A Majority-Based Aggregation Operator to Represent Emotional States

摘要

The Self-Assessment Manikin (SAM) is an univer-sally used instrument of pictographic non verbal measure which is used in many emotional studies in the field of the Psychology. In these emotional studies the usual aggregation operator is the classi-cal mean. In this paper, a new aggregation operator is proposed. This new operator, which is based on the majority concept tries to solve the distribution problems of the mean operator. This new aggrega-tion operator is applied in a real emotional study, in which the SAM is used, achieving better results than the classical mean operator.
