  • Conception and prenatal development

  • Object permanence is minimal prior to age 6 months, but:

  • Itunfolds gradually thereafter

  • Habituation learning is seen as early as 7 hours

Water Level Task (Piaget & Inhelder)

  • Performance improves until, at age 9, it is consistently accurate.

  • However, students in college and graduate school may have difficulty.

  • 50% of men do well, but only 25% of women.

  • Field independent people do better.

  • Mental rotation and error amount correlate
