Define development
The sequence of physical, psychosocial, and cognitive developmental changes that take place over the human lifespan
Scope of Development
The extent to which development influences an individual spans the entire life course - from birth to death.
Normal human development is organized and progressive and usually occurs in a predictable sequence
Delayed ————— Expected ————— Advanced
Attributes and Criteria
Developmental Level Developmental Delay Developmental Milestone Developmental Regression Developmental Arrest
Developmental Level
an individuals stage of development or ability to independently achieve an outcome
Developmental Delay
an essential element of neurological and/or cognitive maturation has not occurred within an age range and should be investigated
Developmental Milestone
an ability or specific skill that most individuals can accomplish in a certain age range
Developmental Regression
the loss of developmental milestones
Developmental Arrest
plateau of developmental change in some category and is noted when chronologic age continues to progress but developmental change does not
Physical/Physiological Development
Includes cellular proliferation, differentiation, and maturation that occurs in each organ and system that allows integrated human functioning necessary for life and health
Physiological growth and development occur in a bilateral and symmetrical way, progressing in a cephalocaudal (head-to-toe) direction and proximodistally (from midline to periphery)
Motoric Development
Generally, motoric development progresses from the achievement of gross motor to fine motor skills - known as refinement.
Gross motor skills
Gross motor skills - involve the use of large muscles to move about in the environment
(ie. sitting, standing, maintaining balance, cruising, walking, running, walking up stairs without assistance, and more complex physical tasks such as playing soccer
Fine motor skills
Fine motor skills - involve the use of small muscles in an increasingly coordinated and precise manner
(ie. batting at an object, reaching and holding an object, transferring an object from hand to hand, holding a pencil in a refined grasp, making marks with a pencil, writing letters, writing words, creating artwork, using hands and fingers to eat, draw, dress, and play)
Fine motor development is contingent upon cognitive and neurological development
Social /Emotional Development
Usually occur in this order → self, others, and social interaction
Knowledge of social and emotional skills is critical because it directs effective communication with an individual(s) and may impact suggested environmental strategies for an individual to obtain optimal functioning.
Cognitive Development
Individuals have an increasing understanding between self and information over time
Development of critical thinking skills and executive functioning, which includes learning, forming concepts, understanding, problem-solving, reasoning, remembering, and thinking abstractly
Combination of cognitive and advanced social/behavioural development enable moral and spiritual development
Communication Development
Articulation
pronunciation of sounds
Voice
production of sound by vocal cords
Fluency
rhythm of speech
Adaptive Development
Piaget’s Theory of Cognitive Development
Period 1 - Sensorimotor (birth to 2 years)
Period 2 - Preoperational (2 to 7 years)
Period 3 - Concrete Operations (7 to 11 years)
Period 4 - Formal Operations (11 to adulthood)
Period 1 Sensorimotor
Birth to 2 years
Period 2 Pre-operational
2 to 7 years
Period 3 Concrete Operations
7 to 11 years
Period 4 Formal Operations
(11 to adulthood)
