Step-by-step explanation:
Siblings relationships have certain characteristics such as closeness, rivalry, and shared experiences. The bond between siblings is often lifelong and can be influenced by factors such as birth order, age gap, and parenting styles. Assimilation, accommodation, and equilibration are cognitive processes described by Jean Piaget that help children modify their existing schemata when they encounter new information. Assimilation involves incorporating new information into existing schemata, accommodation involves changing existing schemata to fit new information, and equilibration is a process of finding a balance between assimilation and accommodation. These processes help children develop and adapt their thinking as they grow.
