This is a concurrent-measures design as the children are shown both versions of the book at the same time and asked to indicate their preference immediately. It is not a longitudinal design as there is no follow-up over time, not a repeated-measures design as the participants are not tested multiple times on the same measure, and not a posttest-only design as there is no control group and no pretest.
