What progress fronts are seen during the sensorimotor stage?

• A. Adapting to and exploring the environment; understanding objects (object permanence); using symbols (like waving or gesturing)
• B. Language development only
• C. Abstract mathematical reasoning
• D. Social role development

Answer: (A)

In the sensorimotor stage, cognition develops as infants learn to act on and make sense of their world. They progress from reflexive actions to purposeful exploration, adapting their movements to discover how the environment responds. A central milestone is object permanence—the understanding that objects continue to exist even when not visible—which typically emerges by about 8–12 months. They also begin using symbols, such as gestures like waving or pointing, and later more symbolic actions, laying the groundwork for language and pretend play. Language and complex abstract reasoning become more prominent in later stages, while abstract math and explicit social-role concepts are not characteristic features of this stage.
