Introduction
Textbook: William A. Yost (2000) Fundamentals of Hearing: An Introduction. (Fourth Edition)
San Diego: Academic Press.
Assignments: There will be 3 quizzes and one paper, each having the same weight. Failure to take an examination on time will result in a grade of "0" unless a legitimate excuse is presented in writing. The paper should be about 5 - 6 pages long (double spaced) and should be based on an analysis of the contemporary research literature. The topic should be cleared in advance. You should be prepared for a 5-8 minute presentation of this same material to the class in the last week of the semester. Examination grades and the paper are graded on a 0 to 100 scale, and not on a curve: a average (mean) score of 90 or more at the end of a course will be an A, 80 to 89 a B, 70 to 79 a C, and so forth. Preparation quizzes will be distributed 1 week in advance, and the actual test will be a sample taken from this handout. You are encouraged to work together and help each other in studying for examinations. You can take make-ups for the first two quizzes if you would like to better your score: your score for that quiz would be the average of the original score and the make-up score. The paper must be your work and in your words. Any material taken from another source must be placed in quotation marks and properly cited. You can get ideas for the paper from any source, but first, it must provide an up-to-date representation of the research literature on the topic that you chose, and second, it must review original research publications.
