Can young preschool children be trained to perform percept deprivation tasks?

Young preschool children aged 2 and 3 years were exposed to a novel paradigm designed to train visual perception skills. The results indicate that children of this age can be trained to perform a percept deprivation task that requires a sophisticated understanding of attention not normally mastered until 3.5-4 years. Results are discussed with reference to engagement, a precursor to an adult-like understanding of perception.
