DeLoache and colleagues convinced children that an "incredible shrinking machine" had reduced the size of a full-size room and now it looked the size of a model room. They hid an object in the model room and reversed the "shrinking machine." They asked children to search in the now full-size room for the larger version of the object. The 2½-year-olds who did not search correctly in the standard scale-model experiments now searched for the object. The researchers' explanation for the finding is that __________.
A. children were more motivated to search because they enjoyed the shrinking machine
B. children remembered where the object was located better in the shrinking machine procedure
C. the shrunken room was no longer a symbol, so the problem of thinking about dual representations was not present in this experiment
D. this procedure enhanced children's attention to details of the experiment and thus improved memory and performance
