The Research Of Psychic Mechanism Of The Variance Of Decision-making

In the decision-making activities people make different decision, only because the same problem in essence is asked in the varied forms. We research the variance of decision-making on psychology. We use the with-subjects design in order to research easily the variance of decision-making. So we research the relation between the cognitive style and the variance of decision-making.We choose six experimentations from the experimentation which psychologists made in the 50 years. There is one isolation effect experimentation and two mental accounting experimentations and two hedonic editing experimentations and one framing bias experimentation. There are 106 undergraduate of Changsha who are voluntary and are not paied. They made six experimentations and one measure. Then we stat and analysis the consequences of experimentations by SPSS11. 0 sofeware. We have four discovers:NO. 1 Except experimentation 2,the variance of decision-making appeared in the within-subjects design. So there is isolation effect and mental accounting effect and hedonic editing effect and framing bias effect on the same subject.NO. 2 Except experimentation 5, there is not the observably relation between the sex and the variance of decision-making.NO. 3 There is not the observably relation between cognitive style and the variance of decision-making in the six experimentations. For people are affected by the context of the extenor more than by the traits of the interor. In the other word, There is no identity between the decision-making and the sentience.NO. 4 There is not the observably relation betweencognitive style and the cumulation of the variance of decision-making in the six experimentations. If we regard the cumulation of the variance of decision-making as "individual style " ,there is no relation between cognitive style and "individual style" .NO. 5 There is not the observably relation between cognitive style and sex. It validated the result which Teacher Zhang educed from experimentations.We hope we can make more experimentations for our idea.
