Answer 1

.Object permanence is the understanding that objects continue to exist even when they are out of

          sight. Piaget's account of this ability is as follows:

               In stages 1 and 2, infants appear to not have any understanding of object permanence.

               Stage 3 infants show that a partial view of something is now enough to remind them of the

               whole (need perceptual cues of existence of objects).

               Stage 4 infants will search for hidden objects, yet show the A-not-B error.

               Stage 5 infants will search for a hidden object wherever it disappeared last from sight, yet do

               not understand invisible displacements.

               Stage 6 infants have a mature understanding of object permanence.

        2.Further Research on Infants' Understanding of Objects

               Earlier ages for reaching object permanence milestones have been noted. An age limitation

               of Piaget's tasks is the need for manual search and memory. Some have used habituation, as

               discussed in Chapter 4, to minimize search and memory constraints. Less stringent criteria

               are used in research presently.

        3.Perception of Partially Hidden Objects

               Some, using variants of a habituation technique, have shown that 3.5- to 4.5-month-olds show

               some knowledge of object properties when the objects are partially hidden.

        4.Evidence of Object Permanence in Stage 3 Babies

               4- to-8-month-olds have some understanding of object permanence (research by Baillargeon

               is presented). Object permanence seems to develop before the ability to mentally represent a

               hidden object's size and location.

        5.Explaining Infants' Search Behavior

               Infants may have trouble with the means-ends behavior required to search for hidden

               objects-lifting a cloth to allow retrieval of a toy under it.

               The A-not-B error may be due to memory limitations.

               The A-not-B error may be due to the inability to inhibit the reinforced response.

        6.Summarizing research on the object concept

               Piaget was accurate about the sequence in which the object concept is acquired but

               underestimated the rate of acquisition.

               Basic understanding of object permanence emerges sometime between 3 and 5 months of

               age.

               Object search behavior lags considerably behind object-related looking behavior.

               The use of research methods that catch more subtle signs of understanding than Piaget's

               methods are still emerging.

Answer 2

object permanence

Answer 3

They don't understand object permanence, meaning they don't understand that it still exists even when they don't see it.
