摘要：This work reports the results of a meta-analytic study about framing effect. An exhaustive literature search identified 51 independent primary studies, published between 1997 and 2003, that fulfilled the selection criteria. The studies produced 151 estimations of the effect size with nearly 13,500 subjects. The effect, measured as d index, was 0.437 for risky frame, 0.260 for attribute frame, and 0.444 for goal frame. The influence of other moderating variables was also analysed, such as gender of participants, design, or response mode. Finally, alternative explanations of the findings and implications are discussed.
