摘　　要： 3个实验探讨了儿童在归纳推理中是否具有多样性效应的争议。实验1采用寻找证据法,使用图片材料,得出5岁儿童在归纳推理中没有多样性效应,表现为典型性效应。实验2改用归属法发现:5岁儿童在归纳推理中表现出多样性效应。实验3采用寻找证据法,但使用实物材料,并且加大了多样性前提的差异程度,结果发现:3岁儿童在归纳推理中也表现出多样性效应。本研究结果表明,在适合的条件下,儿童在归纳推理中能表现出多样性效应。 People are inclined to look for more diversity evidences to support the conclusion in their induction, because more diverse evidence leads to a stronger conclusion. This phenomenon is defined as the diversity effects of induction. Prior researches demonstrated that adults have this useful strategy for evaluating samples that contain single versus multiple pieces of evidence. However, there is a controversy regarding the criteria that children used to evaluate the multiple samples. The main debate is whether or not children who are younger than nine years old have diversity effects in their induction. Some researchers considered that children who are younger than nine years old do not attend to sample diversity to evaluate evidence, because there are important developmental changes in the mechanisms that support human induction. Other researchers held that young children have the diversity effects in their inductive reasoning. Those researchers suggest that the developmental changes underlie the inductive reasoning result from limitations in young children＇s knowledge base. Therefore, they argued that the results that previous studies could not find children＇s diversity performance are artificial as the paradigms or materials they used in their researches were unfit for young children. In order to explore the problem whether young children have diversity effects, three experiments were performed. Experiment 1 used picture materials, and adopted the paradigm of Rhodes, etc. （2008a）; twenty-four children at five years old and forty adults participated in this experiment. Experiment 2 used the same materials as experiment 1, but adopted a more direct technique paradigm; forty children at five years old participated in the experiment. Experiment 3 adopted the same method as experiment 1, but used common objects which children are familiar with as experimental materials; forty children at three years old participated in the experiment. The results of experiment 1 indicated that adults had diversity effects in
