Critical Thinking
- Much of what we have learned about early neural circuits, including migrations and differentiation, has come via animal studies. On what basis can we make conclusions regarding similar processes in the human nervous system?
- How would you design a research study that investigates the relationship between early motor activity and later athletic ability?
- With regards to habituation, explain what happens when you clean out a junk drawer or look at photos you have no seen in many years?
- Figure 5.12 depicts differences in normative gross motor behavior of infants in several countries. Norway is especially noticeable. What are some possible reasons for the cultural difference?
- Your older relative does not want to go to a large social gathering because she has a difficult time with auditory discrimination. She tells you that she no longer wants to pretend that she is listening, as she has done in the past. What advice would you give her?
- What does it mean to “perceive”? What does it mean to “sense”? If a person had a visual, auditory, or other imprairment, how would you know if the problem was one of sensation or perception?
- Compare and contrast major causes of vision loss in industrialized countries versus those that are developing. How are they different? What kind of efforts would you place on prevention versus treatment? How do you think future prevalence rates will change?
