Abstract

1961, Ellsberg When people facing Fuzzy Probability and exact, tend to choose the exact probability of the phenomenon known as fuzzy circumvent. Decades thereafter, the scholars of this particular decision-making phenomenon a lot of research. Among them, most scholars believe that the ambiguity is caused by the lack of information about the missing information more fuzzy greater degree of familiarity with the relatively low natural \In the 1990s, Tversky be improved by fuzzy circumvent experimental classic \However, \to avoid the emergence of the phenomenon. To illustrate the impact of the number of reference information fuzzy circumvent the experiment designed three experiments to study it. Experiment, respectively, in three different rendering conditions to verify the fuzzy circumvent investigated was whether different presentation conditions will exhibit the the \control the number of reference information, respectively, in comparison and comparison conditions directly study the number of reference information for decision-making; indirectly control the number of reference information in the third experiment by the mixed-use object rendering and digital presentation, observed use a variety of presentation fuzzy circumvent. Z-test, chi-square test and single-factor analysis of variance and other statistical methods to analyze the statistics obtained by the experimental found that: (1) in the decision-making process, reference information determines the number of fuzzy circumvent appear. Reaches a certain level, when to choose between the two options with different number of reference information, only two options reference information differences appear fuzzy circumvent; decisions between multiple options reference information on the largest number of a selected number. (2) The presentation of fuzzy circumvent the items also have an important impact. The sensitivity of the test for digital presentation and object presentation, when two presentation at the same time in the decision-making task, will take advantage of object presents information presented as a basis for decision making. (3) presentation and reference number of fuzzy circumvent the emergence, but both fuzzy circumvent the role of different sizes, reference information important and decisive role. (4) the number of reference information and the confidence level between the subjects in this option did not show a significant correlation.
