Papers should be submitted electronically

Phil 12 Winter 2019 Second Writing Assignment Write a short paper (1-2 pages, double-spaced, typed) on the question assigned for your section. These are to be turned in by Noon on Friday, March 8. Papers should be submitted electronically to your TA in .doc or .rtf format. If this is not possible, you may deliver them to your TAs mailbox by Noon. The goal of this paper is to explain clearly the central concepts employed in the question you are to address. Assume that your audience is a fellow student not in this class. To explain the material to that person you cannot just use the concepts we have developed in class but explain them. Present your answers totally in your own wordsdo not quote material either from the website, the lecture powerpoints, or anyone else. A01 Your friend claims that frequently doing brain-puzzles (e.g., Sudoku, crosswords) has improved her cognitive functioning. Design a study to test whether frequently doing brain-puzzles is a cause of (or a causal factor in) increased cognitive functioning. Make clear whether you are doing an experiment, a prospective study, or a retrospective study. Discuss all of the critical factors involved (operational definitions, values of independent and dependent variables, possible extraneous variables, possible confounding variables, etc.). Identify at least one plausible subject and one plausible procedural confound and describe how you would control for them and whether that would be sufficient to ensure the internal validity of the study.
