Study Notes
Research Study Designs
- Cross-sectional: Researchers measure individuals or groups at selected ages within a relatively short period.
Motor Behavior Graphing
- Behavior measurement is typically placed on the vertical axis.
- Advanced scores represented by lower positions on a graph. (False)
Physical Growth vs. Other
- Physical growth: Increase in size or mass from complete body part development.
- Maturation, development, aging, motor change are different concepts.
Aging Population
- Projected percentage of the population aged 65+ in various countries (US, China, Russia, etc.) is 13%.
Dynamic Systems
- Needing an explanation of "Nezhoos" (no information provided)
- Dynamic Systems reflect change. (vs. constant or individual)
Motor Development Constraints
- Categorical constraints are NOT a type of constraint in motor development discussions.
- Includes individual, structural, functional, and environmental constraints.
Motor Development Research Designs
- Motor development research often uses designs involving observation across multiple age groups over shorter time spans. This enables observations of a wider age range. (True)
Constraints in Preschool Obstacle Course
- Environmental constraint: example details needed
- Task constraint: example details needed
- Individual constraint: example details needed
- Functional constraint: example details needed
Motor Development Perspectives
- Information processing: Perspective in the 1960s and 70s, and later years
- Maturational perspective is mentioned .
- Dynamical systems perspective: Approach in motor development
- Perception-action approach: (another perspective)
Rate Limiter and Controller
- "Rate limiter" and "controller" are not interchangeable terms. (False)
Dynamical Systems and Physical Growth
- Dynamical systems perspective does not prioritize physical growth as the most important factor in infant motor development. (False)
Dynamical Systems and Maturational Perspective
- Dynamical systems and maturational perspectives often disagree in motor development. (False)
Biological Systems Development
- Biological (skeletal, muscular, nervous systems) development do not trigger change in physical attributes. (False)
Newton's Laws of Motion
- Movement and forces interplay. (Newton's Laws are described in general terms).
Concept of Forces
- Newton's First Law: A body in motion remains in motion and unchanging unless acted on by some force. (true)
- Newton's Second Law: The acceleration of the movement is proportional to the force; and inversely proportional to the body mass. (Correct formulation)
- Newton's Third Law: For every action, there is an equal and opposite reaction. (True)
Skilled Locomotor Movements
- Skilled movements often show consistent (opposed to variable) oppositional arm and leg motions.
