3V0283.02 Clear Example of Object Concept crudeness -> prefer gradual elaboration (11/01/78)
Relevance: This is another example , albeit a peculiar one, of Peggy having a very crude object concept. she obviously recognizes that objects have an “inside”: This blocks box does — for it can be opened and blocks taken out; her cups have an inside into which balls may fit. It should not be expected that with the discovery of object permanence one “inherits” some knowledge about how surfaces relate to substances. Peggy apparently knows that blocks can go into her box – But she may not yet realize that the lid must be open for the blocks to get inside; so I would interpret her banging them on the lid of the box as an attempt to get them inside. Similarly, when she frequently bangs a ball against the bottom of a cup, I interpret the action as an attempt to get the ball into the cup, but one which does not acknowledge the need to pass through an open face of the object.
