Which of the following is the correct order of Piaget's cognitive developmental stages?

A. operations: “Operations” are internalized, reversible mental actions characteristic of the concrete operational stage, not attributing intention to inanimate objects.
B. conservation: Conservation refers to understanding that quantity remains constant despite changes in appearance; it’s unrelated to saying a root is “mean.”
C. animism: Animism is attributing humanlike qualities or intentions to inanimate objects (e.g., a root being “mean”).
D. egocentric thought: Egocentrism is difficulty taking others’ perspectives; while common in young children, it does not specifically describe attributing agency to objects.

A. dynamic systems: Esther Thelen proposed a dynamic systems view of motor development, emphasizing how motor behaviors emerge from the interaction of multiple subsystems (body, brain, environment).
B. perceptual systems: Perceptual systems refers to sensory-processing frameworks; it’s not the name of Thelen’s motor development theory.
C. bio-psycho-motor: “Bio-psycho-motor” is not a recognized label for Thelen’s theory; it mixes domains but isn’t the established term.
D. bio-behavioral: Bio-behavioral could describe interactions of biology and behavior broadly, but it’s not the specific theory Thelen formulated (dynamic systems).
