DeLoache and Her Colleagues Showed Children Either Photographs or Miniature

DeLoache and her colleagues showed children either photographs or miniature models of a room. Children were then shown, using either the photograph or the model, where a toy was hidden in the "real" room. Children then entered the real room and were asked to find the toy. DeLoache reported that the youngest children (2 year olds) were

A) better able to solve the problem with the model than with the photographs; the greater similarity between the model and the real room made the task easier.
B) better able to solve the problem with the photograph than with the model; the photograph was less interesting as an object than the model, making it a more effective representational tool.
C) able to solve the problems with both the model and photograph equally effectively; children have implicit knowledge about object representation, which can be demonstrated as soon as they are old enough to perform the task.
D) unable to solve the problem with either the model or the photograph; representational insight develops slowly over the preschool years, and is not demonstrated by 2 year old children for any representational medium.
