After explaining the study to your child, we will show your child 80 items on a computer screen with a colored border in either in red, green, blue, or yellow. Following a short break, we will show your child 160 items on the screen. Half of these items were previously displayed and half of these items are new. We will ask your child two or three questions: Have we shown you this item before?How sure are you about your response? Your child will be given the choice of one of three categories: Very sure / halfway sure / not sure. What color was it? This question will only be asked if the answer to question 1 was yes.This portion of the test takes about 30 min. Subjects will then participate in a similar test of picture recognition, but we will ask about the location of the original image instead of the color. Your child will then be given a standardized intelligence test. This takes roughly 45 min to an hour to complete.
