RESEARCH STUDY: Dr. Ickes is interested in studying the potential causal relationship between doing homework and academic achievement. In January, Dr. Ickes has her students report their Fall GPA (a measure of academic achievement) and estimate how many hours they spent doing homework during a typical week in the Fall semester. In April, Dr. Ickes measures the same variables again (the estimated number of hours spent doing homework during a typical week in the Spring semester and their Spring GPA). She finds the following correlations.   What type of study is Dr. Ickes using?

PLEASE NUMBER YOUR RESPONSES 1-7 BELOW. At times, self-reports are imperfect. For example, participants might use a response set such as “fence sitting” or engage in “socially desirable responding”, both of which can pose problems to a measure’s construct validity. In the space below, answer the following questions regarding these concepts. What is “fence sitting”? Be specific. Why might a participant engage in fence sitting? How can a researcher solve the problem of fence sitting? In other words, what is a possible solution? What does it mean if a participant is engaging in “socially desirable responding”? Why might a participant engage in socially desirable responding? How can a researcher take care of this problem? In other words, what is a possible solution? Why do fence sitting and socially desirable responding pose a problem for construct validity?
