1 to 4 months
Infants repeat pleasurable behavior that first occur by change (such as thumb sucking). Activities focus on the infant's body rather than the effects of the behavior on the environment. Infants make first acquired adapatations; that is, they suck different objects differently. They begin to coordinate sensory information and graspy objects Behavior- when given a bottle, Dylan who is usually breast fed, is able to adjust his sucking to the rubber nipple |

4 to 8 months
Infants become more interested in the environment; they repeat actions that bring interesting results such as shaking a rattle and prolong interesting experiences. Actions are intentional but not intially goal directed. Behavior- Amy pushes pieces of dry cereal over the edge of her high chair tray one at a time and watches each piece as it falls to the floor |
Secondary circular reactions

8 to 12 months
Behavior is more deliberate and purposeful (intentional) as infants coordinate previously learned schemes such as looking at and grasping a rattle and use previously learned behaviors to attain their goals such as crawling across the room to get a desired toy. They can anticipate events Behavior- Anica pushes the button on her musical nursery rhyme book and a song plays. She pushes this button over and over again choosing it instead of the buttons for other songs |
