| 0-3 Months | Regulation: The infant self-regulates physiological behaviors – crying, kicking, swallowing, sucking, burping, smiling, turning, etc. |
| 3 – 4 months | Coordination: The infant coordinates sights and sounds in the immediate environment. The infant organizes visual, auditory, tactile, and sensory information. |
| 4 – 10 months | Prehension: The infant grasps, reaches, and voluntarily releases objects. |
| 7 – 12 months | Imitation: The infant acts and reacts; the infant repeats pleasurable activity; the infant initiates. The infant delays imitation for a short period of time |
| 9 – 18 months |
Spatial Relationships: The infant achieves spatial reasoning, locating objects in space perceiving visual yields, achieves depth and peripheral vision; scans in vertical and horizontal planes. Cause and Effect Relationships: The infant causes a change to occur and acts on the outcome. Means / Ends Relationships: The infant apprehends a tool and uses it to cause another behavior to occur. Object Permanence: The infant comes to know that objects out of sight are still there; the infant perceives hidden objects as “findable,” not gone forever. Temporal Relationships: The infant achieves temporal reasoning past the present |
Progression of the object concept:
| 0 – 7 months | object awareness - object recognition- object familiarity - object preferences - object manipulation |
| 7 – 12 months | object permanence - object localization - object identification - object labeling and pointing - object attachment |
| *12 – 24 months | object displacement - object reference - object classification - object seriation - objects change into ideas and words - object representation |
| * 24 – 36 months |
are reinforcement months for these concepts of association. Intellectual rehearsals period: Adaptation - Multi-sensory integrated curriculum |
