There are only a handful of signaling pathways (FGF, WNT, BMP/TGFB, HH, Notch, steroid) that shape development. Which one do you think is the most important? Sketch the signaling pathway (ligand, receptor, intercellular signaling). Defend the importance of your choice with specific examples. Identify a human disease caused by changes in this signaling pathway. Propose a way to treat the condition by modulating the pathway with genetic technology.

The text discusses several methods of studying human behavior. These include the case study, naturalistic observation, correlational research, survey research, and the experimental method. If you were going to design a study investigating the relationship between alcohol and violence, which of these methods would you choose and why? What would be the relative strengths and weaknesses of this study? What ethical considerations must be taken into account while undertaking this study?

What are the two early schools of thought in psychology (structuralism and functionalism) and what was their approach to their subject matter? What are the six main perspectives we find in psychology? It is important that you know the differences between these perspectives in terms of their explanations for human nature, causes of behavior, and the main methods and strategies employed. What is the levels-of-analysis framework? You may be expected to apply the levels-of-analysis to a set of behaviors and/or cognitions.

One main consequence of the Civil War was the abolition of slavery. For the first time, some four million blacks living in the South faced life as freed people. Regarding the emancipation of slaves: What tensions and conflicts emerged between the ideal that all human beings are created equal and the previous existence of slavery and ongoing racial prejudice?

Using evidence provide at least two distinct consequences of this tension and conflic.

Long essay question:

Question 2) Explain how economists calculate the rate of return that individuals get from investments in their human capital and basic empirical results of these calculations. A perfect answer will explain the types of costs/benefits included in these calculations, how the actual calculation is done (You are not expected to do this calculation) and empirical results. Use only material provided in this course to answer this question. (18 pts)

Contemporary psychology (for some theorists) holds that our memory systems can be modeled after the modern-day computer. Using this model, one can say that the

human memory system has to translate incoming information into a meaningful code ("encode"), store the information, and retrieve the stored information at will, much like the operation of

a sophisticated computer. Is William James's notion of "memory" consistent with this modern day analogy? Why or why not?

Discuss whether the human capital and signaling models have different implications for each of the following education policies:

a. Providing financial aid to students for college.

b. Introducing a test that high school students could take to provide reliable measures of task commitment and capacity to work effectively in teams.

c. Increasing the age at which students can drop out of high school from 16 to 17.
