15
Object permanence (p. 250) The realization that
objects continue to exist when they are no longer
visible or detectable through the other senses
16

• Table 7.2 Summary of Piagets account of
  sensorimotor development

17
A-not-B error (p. 250) Tendency of 8- to
12-month-olds to search for a hidden object where
they first found it even after they have seen it
moved to a new location
18
Object Permanence

• Development of invariants
• Progressive decentering

19
Preoperational Period (2 to 7)
20
Symbolic function (p. 255) The ability to use
symbols (for example, images and words) to
represent objects and experiences
21
Evidence for Representational Ability

• Stage 6 of object permanence
• Deferred imitation (p. 249)
• Symbolic play
• Language
• Inner experimentation (p. 249)

22
Preoperational Limitations

• Egocentrism (p. 258) The tendency to view the
  world from ones own perspective while failing to
  recognize that others may have different points
  of view

23

• Figure 7.3 Maynard the cat, without and with a
  dog mask. Three-year-olds who met Maynard before
  his change in appearance nonetheless believed
  that he had become a dog.

24
Preoperational Limitations

• Egocentrism (p. 258) The tendency to view the
  world from ones own perspective while failing to
  recognize that others may have different points
  of view
• Centration (p. 259) In Piagets theory, the
  tendency of preoperational children to attend to
  one aspect of a situation to the exclusion of
  others
