Dynamic Systems theory

QuestionAnswer
What is Dynamic Systems Theory (DST)? A theory that proposes behavior emerges from the interaction of multiple subsystems over time.
What is a dynamic system? A complex system that changes over time due to interactions between multiple subsystems, often in nonlinear ways.
What does “nonlinear change” mean in DST? Behavior does not change in a steady or predictable way; it can be variable and sudden.
What are personal resources? Individual characteristics and abilities that influence movement (e.g., strength, vision, motivation).
Give examples of personal resources Strength, perception, cognition, neuromotor system, motivation, postural control.
What is meant by developmental trajectories? Each personal resource develops at a different rate over time.
What are the three constraints in Newell’s model? Individual (personal resources) Task Environment
How do constraints affect behavior? Behavior emerges from the interaction of these three constraints.
What is self-organization? The spontaneous emergence of coordinated behavior from interacting subsystems.
Are behaviors continuous in DST? Yes, behaviors develop continuously and build on each other.
Can behavioral patterns be stable or unstable? Yes, both.
What is context? The environmental and situational conditions surrounding a behavior.
What is a task? The goal or objective of a movement.
What is an attractor? A preferred pattern of movement (e.g., walking vs. crawling).
What is an attractor well? A representation of how stable a movement pattern is.
What is a nonlinear phase shift? A sudden change from one movement pattern to another.
What is a control parameter? The factor that triggers a shift to a new behavior.
What are intrinsic dynamics? The internal properties of a system that influence behavior without task demands.
What are collective variables? A: Simplified measures that describe coordinated movement patterns.
What does modeling the attractor dynamic mean? Explaining movement behavior using physical laws.
Why don’t infants suddenly start walking? Because behavior emerges from interacting subsystems and requires a control parameter to trigger change.
Why might behavior vary during learning? Because the system is unstable and exploring new movement patterns.
How does DST differ from maturation theory? DST emphasizes interaction of multiple factors, not just biological development.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
