Abstract: The Stroop paradigm was adopted to investigate the cue of analog magnitude representation.Participants were 30 adults.In one task,the participants were asked to choose the set which has larger number of elements.In anther task,the participants were asked to choose the set which has larger continuous amount.It was shown that the Stroop effect only occurred in continuous amount task,but not in elements number task.From the further analysis we found that the congruent degree between discrete quantity and continuous quantity influence both tasks. These results suggest that both continuous and discrete quantity may be extracted automatically from a scene and represented internally,and it was much more difficult to restrain discrete quantity than continuous quantity which leads to Stroop interference.

Key words: analog magnitude representation, discrete quantity, continuous quantity, Stroop paradigm
