SENSORI-MOTOR STAGE   0–18 months(or less)

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
