Explain how Thelen's research on infant stepping behavior revolutionized what researchers understood about early infant motor development.

Stable posture affects all of the following except

Dr. Tay is interested in examining at what age infants' visual acuity improves. She shows infants of various ages two photos of the same object, a flower. In one of the photos, the picture is slightly blurred. In the other photo, the picture is sharp. Based on the concept of preferential looking, if infants can see the difference between the two photos, they will likely

To what extent did McGraw's research on twins Johnny and Jimmy challenge Gesell's hypothesis about the role of biology in explaining infant motor skills development?

Ainsley was looking out the window of her parents' car as they were taking a trip to the beach. To her eyes, it appeared as though the trees and fences nearest to the car went past her very quickly, but the large clouds overhead moved very slowly, a phenomenon known as

You are preparing to give a seminar on healthy eating to a group of expecting women.

Based on what you know about infant eating preferences, how would you present this point?

Laticia loved eating spicy foods when she was pregnant, while Anne preferred foods that were heavily salted. Their interests in these foods continued as they breastfed their babies. Given what you know about the development of infant taste preferences, it is likely that

Which of the following statements correctly summarizes the contribution of Thelen's research to the understanding of infant motor development?

One explanation advanced for the "attractiveness effect" in infants is that

Molly and her mother are playing with several different size balls in their living room. With the small balls, Molly has learned how to grasp them in her hands and throw them back towards her mother. With the larger balls however, when Molly attempts to grasp them, as she touches and tries to hold them, she finds it is too difficult to do. As a result, she switches to rolling them back and forth. Which concept explains Molly's behavior?

Infants were initially habituated to the category "vehicles" by being shown images of different cars and trucks. Following this, they were shown a picture of a school bus next to a picture of an apple. Based on your knowledge of how infants form categories for different objects, which of the following statements would best illustrate how infants would respond?

Which of the following structures in the retina is responsible for determining the overall visual acuity of infants?

Explain how the "back to sleep" movement influenced infants' ability to progress through certain motor milestones.
