Alan S. Brown and Chris Logan wrote in "The Psychology of The Simpsons" that Grampa has the least amount of "power" in the Simpson family, and that he is treated as little more than a child and is often ignored. The family frequently laughs at his "failing" memory and his "ineffectual" attempts to get what he wants. They added that Grampa is left behind, forgotten, and rarely invited to spend time with the family. The authors commented that he is "not without influence, but he certainly does not play the traditional grandfather role in the family hierarchy."
