What is a key characteristic of the invention of new means through mental combination in early development?

The invention of new means through mental combination, a concept rooted in cognitive development, primarily aligns with evidence of deferred imitation. This refers to the ability to replicate an observed action after a delay, indicating that a child can mentally represent the action even when the model is not present. This capability demonstrates a child's cognitive advancement in memory and understanding, suggesting they can internalize actions and later reflect them in their own play or behaviors.

In the context of early development, deferred imitation showcases how children can combine learned behaviors and actions from their environment in novel ways. The emergence of this skill is crucial as it signals a shift in cognitive abilities, reflecting a growing capacity to engage in complex thought processes rather than just reacting to immediate stimuli.

While increased verbal communication, logical problem-solving skills, and social play are also important developmental milestones, they focus on different aspects of cognitive and social growth rather than the specific mental combinations associated with deferred imitation. Thus, the right answer captures a primary developmental characteristic linked directly to how children begin to use their cognitive abilities to create new outcomes from observed experiences.
