Chapter 5: Cognitive Development in Infancy and Toddlerhood The Growing Child by Denise Boyd & Helen Bee 1. What does sensorimotor intelligence refer to? A baby assimilates incoming information into the limited array of schemes they are born with and accommodates those schemes based on their experiences. 2. Describe the circular reactions. The many simple repetitive actions seen at this time each organized around the infant’s own body. 3. According to Piaget, when are infants first able to use symbols? Piaget thought that the baby still did not have mental symbols to stand for objects in this substage. 4. What is object permanence? When does it develop? Object permanence is the understanding that objects continue to exist when they can’t be seen. At about 2 months of age. 5. What is a delay in object permanence associated with later? 6. How have researchers since Piaget (e.g., Baillargeon) shown that object permanence occurs earlier than Piaget thought? Researcher have used computer technology to keep track of how infants’ eyes respond when researchers move objects from one place to another. These “looking” studies have demonstrated that babies as young as 4 months show clear signs of object permanence if a visual response rather than a reaching response is used in the test.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
