Document Summary
Ans: represents large numerosities: study that showed dots increasing in size. Object tracking system and object representation system: cracker choice experiments. Child sees experimenter put crackers in one bucket, then in the second. Let baby pick a bucket logic is they will go to the bucket with more crackers if they are tracking how many crackers are in the bucket. When you put 3 vs. 4 crackers, performance is to chance, they choose randomly. You overwhelm the system: manual search experiment. Infant can retrieve one ball and experimenter secretly removes 2nd ball. Box on table, places 2 balls on box, hides them inside. 2 objects (1 remaining trial): infants searching is measured, ball expected inside. 2 objects (expected empty trial) infants searching is measured, box is empty. At step 4, search for longer time then after when they see the experimenter remove it.
