Which of the following describes the sensorimotor stage of cognitive development?

The sensorimotor stage of cognitive development is accurately described by the time frame it encompasses, which is from birth to approximately age two. During this stage, infants learn and understand the world primarily through their sensory experiences and motor activities. They engage with their environment through actions such as looking, grasping, and manipulating objects, which helps them develop fundamental cognitive skills. This period is critical as infants begin to understand the concepts of object permanence and cause-and-effect relationships.

The other descriptions do not accurately represent the sensorimotor stage. The use of symbols and language is characteristic of later stages, particularly the preoperational stage. Moreover, complex reasoning strategies emerge even later in cognitive development, particularly in the formal operational stage. Additionally, the sensorimotor stage is not the final stage of cognitive development, as there are several subsequent stages that build on the skills acquired during the sensorimotor phase.
