Attention is often captured by the sample of the project that is to be done. The evaluation of whether their performance matches the sample may be done independently or in response to a prompt that asks: "Is yours like the sample?" When the error is in a striking cue, they are usually able to fix it. The sample may be checked several times and errors corrected while working on a project. At the end, they can evaluate the finished product, compare it to prior experiences and express satisfaction or displeasure with what they did.
