CHOOSE 1 OF THE FOLLOWING QUESTIONS AND ANSWER IT THOROUGHLY IN SPACE PROVIDED BELOW.

1.            Several years ago, two adolescent boys entered their high school (Columbine) wearing black trench coats and carrying weapons, which they used to kill a teacher and classmates before turning the guns on themselves.   This question is based on actual events, and the test review noted the link for additional information. Unless you read the additional information or know a great deal about this incident I would not recommend choosing this question.

Given the discussion in chapter 1 of the many contributors to human development, and using Bronfenbrenner's ecological-systems approach and terms, explain four (4) possible contributors from at least three (3) levels  of the systems theory to what happened. Tie the contributors specifically to the levels. Be specific.

2.          You are going to baby sit for a family with three children. When the parents are ready to leave, each child acts differently. You can assume that the children are securely attached. The oldest, Katia, is 28 months, the middle child, Piet, is 14 months, and the youngest, Mia, is two months old. What differences among the children would you expect to see in attachment behaviors and why?

3.         You have been hired by a research institution to design a study to examine the effects of a drug (used by physicians to control expectant mothers' nausea over the course of a pregnancy) on infant hearing at birth, 6 months and one year. Briefly explain how you might do this using a cross-sectional design, noting benefits and drawbacks. Then explain what a longitudinal design is and how it would improve on your original approach.
