Study Notes

Physical Development

Physical development encompasses changes in size and shape, including height, weight, bone growth, muscular development, and visual/spatial awareness.
Constraints, such as disabilities or impairments, can affect how people perform tasks in unique ways.
Genetic factors significantly influence characteristics like height, blood type, and hair color, and affect the timing of growth and strength loss.
Extrinsic factors like prenatal nutrition, drug ingestion, and x-ray exposure also impact growth.
Extensive practice can also account for exceptional abilities.
Nature refers to pre-wiring and genetic inheritance, while nurture refers to external factors after conception.

Growth Curves

Growth charts track children's and adolescent's height and weight.
Percentiles help determine if a child is growing within a normal range or if there's a potential issue.
Growth curves, including the rate of change. Growth is often rapid after birth, as well as in adolescent development, and these are not smooth lines, but instead curvilinear plots or curves.
Key factors for monitoring growth, such as height and weight, must be considered to ensure appropriate ranges.

Body System Constraints

The skeletal system provides structural support and enables movement.
Bone changes continue throughout adolescence, but it is also a living tissue which is constantly undergoing remodeling.
Skeletal growth involves both bone building and resorption, with more bone building during development stages than in adulthood.
The muscular system is crucial for motor skills, influenced by muscle mass, maturation, and factors like nutrition and exercise.
Muscle strength and function tends to peak in the late teens and 20s.
Cardiovascular system function is vital for physical activity. Healthy heart rate changes with age and can be affected by physical activity.
The nervous system controls movement and behavior. Neural development occurs rapidly in early life, with the formation of neuron connections.
Sensory system, including vision, hearing, and kinesthetic perception, are essential for movement. Vision and hearing declines can occur over time for some individuals as they age, but also have a variety of other factors which contribute.
The endocrine system regulates hormones, influencing growth, mood, and energy production. This system affects a number of physiological processes, such as hormone functions, and these may decline with age.

Proportion Growth Curves

Motor learning and development, in children and adolescents is related to stature, weight changes in bodies shape, in addition to growth of different parts of the body.
Head, shoulders, hips, and knees all grow at different rates. During prenatal periods, the head grows faster than the other parts of the body.
Children and adolescents have diverse proportionate development rates based on how specific parts of the body grow.
Proportional changes in growth rates can have an impact on movement patterns, especially during puberty.

Sensory System

Sensory development occurs from birth and gradually throughout life with influences on movement, perception, and skillful performances.
Vision, hearing, kinesthetic perception, and other senses shape movement experiences.
Older adults may have age-related visual or auditory changes that can affect daily activities.

Memory for Movement

Declarative, conceptual, and procedural knowledge are types of memory that interact.
Declarative knowledge refers to factual and conceptual information stored, whereas conceptual knowledge includes understanding rules, and procedural is for performance of action.
Knowledge is related to memory, each influenced by strategies, and use of strategies may change over time (such as during childhood, adolescence and adulthood).
Memory's role in activity for movement can be helped through visual imagery, verbal labels, and other methods.

Self-Determination Theory

Self-determination theory posits three basic needs (competence, autonomy, and relatedness) are essential. These impacts motivation in people.
Individuals have a personal agency to participate actively in actions that benefit them.
People's interest are positively influenced by their belief, that they have the capability to successfully perform the action.
Self-efficacy supports confidence levels, by focusing on one's ability and capability to perform a desired behavior. Motivation is also influenced by social interaction and relationships.
The quality of experience and motivation (e.g., self-regulation) are essential for development of competence.
Focus on positive expectations to promote self-regulatory behavior.

Psychosocial Development

Psychosocial development is characterized by eight stages, impacting development from infancy to adulthood.
Each stage is defined by specific psychosocial conflicts that individuals attempt to resolve.
Positive resolutions can promote competence, autonomy, and a sense of self.
Negative resolutions can result in psychological tensions and difficulties during later stages.
Successful development of each stage helps children to attain the most successful integration into society.

Cognitive Development

Piaget's theory includes four stages:
Sensorimotor (birth to 2 years): infants focus and develop knowledge of the world.
Preoperational (2 to 7 years): children's thinking becomes more symbolic and egocentric.
Concrete operational (7 to 11 years): children develop logical thinking skills, whereas
Formal operational (11+ years): adolescents and adults can use abstract thinking and problem-solving.
Cognitive changes occur in these stages progressively based on age, and learning from these changes impacts performance.
