"Observation 2. Laurent, age 0; 2 [0 years, 2 months]. I look at him through the bars of his wicker cradle and from time to time there are approximately the same place; Laurent then looks at this place when I was not there, and it is obviously waiting for me to show up there again "(p. 9). "The child is only looking at the place where the object had disappeared: so he simply some time retained the position of the earlier perception, and if the object does not appear again, he soon forgets about it. If in the child's mind there was a general idea about the subject ... he would have been actively trying to track down the missing object ... But the kid obviously does not know what can be done because the missing object is not yet perceived by the child as something that constantly exists that somewhere moved; for him it's just some kind of way, which disappeared from his field of vision, it goes nowhere. And there is there, without any objective reason "(p. 11).
