Postnatal Development Flashcards
What are the 9 developmental stages?
Prenatal
Infancy and Toddlerhood
Early Childhood
Middle Childhood
Adolescence
Late Adulthood
Death and Dying
What is the prenatal age stage?
period of the egg: first 2 weeks
Embryonic stage: conception to 8 weeks
Fetal stage: 8 weeks to birth
What is the infancy age stage?
Neonatal: birth to 22 days
Birth to onset of walking (about 1 year old)
What is the toddler age stage?
1-4 years
What is the childhood age stage?
Infancy to 7 years old
What are the two developmental directions of physical growth?
Cephalocaudally
Proximodistal
What are the characteristics of motor development?
In a predictable sequence
At a variable rate
As a continuous process
From simple to complex
From general to specific
What is Scammon’s Growth Curve?
Not all tissue systems grow at the same rate
Scammon’s growth curve is a summarization of the differential nature of postnatal growth
By age 1, most children have accomplished what in regards to sensory and motor development?
Like to put things in mouth
Pull up to standing position by holding onto furniture
Cruise
Have mastered grasping objects
By age 1, most children have gotten where in regards to physical development?
Have grown taller
Gotten heavy (3x weight)
Big heads
Still have a baby look, respective of head and body proportions
Will likely have a few teeth
What is Gallahue’s hourglass model of motor development?
Reflexive movement phase + rudimentary movement phase+ fundamental movement phase+ specialized movement phase
All mix together and lead to motor control and movement competence
= Lifelong daily living utilization+ lifelong recreational utilization+ lifelong competitive utilization
This is influenced by individual and environmental factors
What is Clarke and Metcalfe’s Mountain of Motor Development?
Bottom to top of mountain
Reflexive
Preadapted
Fundamental motor patterns
Context-specific
Skillful
Compensation may happen during the context-specific and skillful stages
What is the movement and motor skills classification?
Motor aspect (gross or fine skills)
Temporal aspect (discreet/serial/continuous)
Environmental (open or Closed KC)
Functional (stability/locomotor/manipulative)
What are the three task based classifications of movements?
Stability: emphasis on static and dynamic body balance
Locomotion: emphasis on body transportation
Manipulation: imparting force on or receiving force from an object
What are the phases of movement/motor development?
reflexive: involuntary subcortically controlled movement in utero and early infancy
Rudimentary: movements of infancy influenced by maturation
Fundamental: basic movement skills of childhood
What are the fundamental movement developmental stages?
Initial stage
elementary stage
Mature stage
What are the landmarks of physical achievement?
Fine motor skills: skills involving small muscles used in manipulation
Development of hand control:
At birth: grasping is reflexive
3 months: grasping becomes voluntary (ulnar grasp)
9-12 months: pincer grasp: use of thumb
What does cognition/language/psycho-social readiness depend on?
Maturation and learning
Convergence of biological factors within the individual
Applies to both cognitive and motor domains
What are implications for educational programming?
Strong base
Social support
Socioeconomic status
Parent education
What is plasticity?
The degree to which a developing structure or behavior is modifiable due to experience
What are Piaget’s stages of cognitive development?
Sensorimotor (birth-2yo)
Preoperational (2-6/7yo)
Concrete operational (7-11yo)
Formal operational (12-adulthood)
