Gross motor skills include activities such as running, whereas fine motor skills include activities such as

A. egocentrism: Egocentrism is the child’s difficulty seeing others’ viewpoints; covering toys because they might be cold reflects attributing internal states to objects, not perspective-taking failure.
B. operations: Operations are internalized, reversible mental actions (Piaget); this behavior is not demonstrating logical operations.
C. animism: Animism is attributing lifelike qualities or feelings to inanimate objects (e.g., thinking a toy can feel cold), which fits this example.
D. conservation: Conservation is understanding that quantity remains the same despite changes in appearance; it’s unrelated to attributing feelings to toys.

A. slow-to-warm-up: Slow-to-warm-up children are cautious and adapt gradually to new situations; they are not typically described as generally positive, regular, and calm.
B. uninhibited: “Uninhibited” is a temperament label associated with Kagan (high approach, low fear) rather than Chess & Thomas’ categories, so it’s not the expected label here.
C. easy: The “easy” temperament (positive mood, regular routines, adaptable/calm in new situations) exactly matches Natalie’s description.
D. difficult: Difficult children show irregular routines, negative mood, and intense reactions, which contradicts Natalie’s calm, regular behavior.
