Peds Cog Skills
Normal Development of Cognitive Skills
Age | Sensorimotor Period | Cognitive Milestones |
---|---|---|
1-2mos | Reflexive Stage (1mo) | Closely associates all sound w/mvmnt. Uses abdomen to breathe, displays rhythmic breathing patterns at rest. Explores environment by mouthing obj. Stops all act/experiences a chage in breathing patterns while focusing on obj or person. Smoother tracking. |
3-5mos | Primary Circular Reactions (2-4mos) Repeats reflexive sensorimotor patterns for pleasure | Hand on bottle & finds mouth. Transitions from watching own hands 2 mouthing hands. Increases variety of sounds;less nasal crying. Concept of obj permanence. Transitions from searching 4 only dropped obj to partly hidden ones. Pats bottle when feeding. |
6mo | Secondary Circular Reactions (5-8mos) Begns showing voluntary mvmnt patterns. Repeats actions that create pleasurable sensations. Primitive awareness of cause and effect. | Call out for attention. Repeats sounds. Increase varied sounds. Increases dissociation of sounds from mvmnt. Understands concept of cause/effect & repeats certain patterns of action to achieve a particular result. |
7-9mos | Circular Reactions (2-4mos) | Puts objs into containers. Copies mvmnts (banging objs). Begins searching for objs in containers. Responds to "NO". Explores spatial concept such as in/out & on/off by experimenting with different mvmnts while playing. |
10-12mos | Coordination of secondary Schemata (9-12mos) Begins participation in obj permanance problem-solving act, begins decentralized thinking | Shows desire for (I) in motor development/skills. Follows simple directions. Uses obj to reach goal in (I) problem-solving act. |
13-18mos | Tertiary Circular Reactions (12-18mos) Begins tool use, serches for new schemes | Trial/error problem solving. Uses obj conventionally/begins to group. Uses speech to name, refuse, call greet, protest/ express feelings. |
19-24mos | Inventions of New Means Through Mental Combinations (18-24mos) Shows insight,uses tools purposefully, mental representation, develops stability to use mental presentation | follows 2-step directions, understands obj permanance/engages in systematic searching. Speech used as means of communication. |
Birth to 37-40wks of gestation | Reflexive Stage Begins dispay of primitive reflexes. Doesn't differentiate between self/objs or between sensation/action. | Uses entire body during vocalizations. Uses abdomen to breathe. Become quite in response to voice. Slowly tracks moving obj. |
