In order to investigate a rating order effect， seven circles were presented horizontally in a pair. Sixty subjects estimated the apparent sizes of the set of 56 samples by a task of seven category rating. Subjects judged both left and right circles of the pair. There were rating order conditions， i.e.， starting with rating of left or right circle， and near and far distance conditions for two circles. The results are summarized as follows: (1) The results under near and far distance conditions were similar. (2) The larger circles with a smaller circle were rated larger than the same circles in pair. (3) The smaller circles starting with the larger circle were rated larger than the smaller circle starting with the smaller circle， revealing a rating order effect. The rating order effect was selective for the smaller circle， and there was no rating order effect for the larger circle
