Question

The infant may be responding to aspects of the stimulus different than those identified by the investigator这句话怎么翻译?than在这里是什么意思
（下面是这句话的原文 The third,and most potent,limitation is that it is not possible to be certain that the infant's response was due to the stimulus presented or to a change from no stimulus to a stimulus.The infant may be responding to aspects of the stimulus different than those identified by the investigator.Therefore,when observational assessment is used as a technique for studying infant perceptual abilities,care must be taken not to overgeneralize from the data or to rely on one or two studies as conclusive evidence of a particular perceptual ability of the infant.）

Answer 1

这里的than是与different连用的
