- Preoperational stage
- concrete operations stage
- formal operations stage
what is the sensrimotor stage
from birth to about 2 years of ages, marked by the focus on here and now. infants lack mental representation- the ability to think about things that are absent from immediate surrounds. also deffereed the ability to preform an action observed earlier, is alsoabsent from the sensorimotor
what is object presence
