Final answer:
Jameson, by picking up blades of grass, is exhibiting Assimilation, where he is integrating new sensory experiences with existing schemas about the texture and appearance of grass.
Step-by-step explanation:
One-year-old Jameson is sitting on the sidewalk picking up blades of grass after his mother mowed the lawn. In this scenario, Jameson is using A. Assimilation. Assimilation is a cognitive process defined by Jean Piaget that involves integrating new information into pre-existing schemas (the mental structures we have about the world). For instance, a child who has learned what grass is might apply this existing schema to all green, leafy textures they encounter.
When Abdul, a 2-year-old, calls various dogs in his picture book as "dog," based on his experience with the family's Labrador retriever, he is assimilating these new examples into his already established dog schema. Similarly, Jameson is likely using this cognitive process to understand the grass blades, by placing them into his existing understanding of objects and sensory experiences.
Other options like B. Accommodation (altering existing schemas or creating new ones in response to new information), C. Object permanence (the understanding that objects continue to exist even when they cannot be observed), and D. Deferred imitation (reproducing a behavior observed at an earlier time) do not directly apply to Jameson's behavior in this context.
