Description of the course:

This is an introductory survey course on perception. Historically , the study of perception is one of the first areas to emerge in psychology, and is concerned with the question of how we know the world. Answers involve being able to bridge three topic areas: a description of the stimulus (what is light?), how our bodies react to that stimulus (what is happening on the retina?), and the relation of both of those to our perceptual experience (What a delicious looking apple!). So be prepared to do skipping back and forth as we will integrate physics, physiology, and phenomenology.

The course is broken into four sections. The first section is concerned with the psychophysical method. This sections covers the methods by which people establish the relationship between physical events and subjective experience. The psychophysical method is both a philosophy about how to think about the world and a set of techniques derived from that philosophy. Next we will move to vision, the most investigated system. We will begin with some basic physiology and then move into an analysis of brightness, color, and form. In the next section, we will examine the perception of space, motion, and form (again). In the final section, we will cover audition, the next most investigated system. In all cases we will be connecting 3 descriptive systems-- physics, physiology, and the perceptual experience.

One of the fun aspects of studying perception is that the effects are easy to see with just one subject, and that subject can be yourself. SO I do many mini-experiments/demonstrations in class I put the demonstrations and figures on my website so that you can look at them at other times. Plan on visiting my website often. Go to http://www.acs.appstate.edu/~kms and click on the link to this class. The "Topics" link will take you to the in-class material.

The class schedule below is a brief version of the topics webpage. Go to the topics webpage to see all the details. You may want to print it out so that you can make notes about the flow of the course. For example, I may suggest focusing on a particular link or ignoring a link.

Tests, grades, and your busy schedule:

There will be four multiple-choice tests during the session. The percent correct for each test will be averaged across the four tests to compute your final grade. I will post a study guide and there will be a question and answer period preceding each test. Come prepared and use it to your advantage.

There is a multiple-choice final exam. Your final grade is based on the average of 4 exams. If you have taken 4 exams and are happy with your grade then you do not have to take the final exam. If you have taken 4 exams during the semester, and the final exam, then your grade will be based on your 4 highest scores. If you miss an exam during the semester then the final exam serves as the "make-up" exam. You can only make-up one exam.

The final letter grade will be assigned on a 10- point scale (100-90, A; 89-80, B; 79-70, C; 69-60, D; below 60, F). Pluses and minuses will be assigned for averages that are 2 points from a higher or 2 points from a lower grade (e.g., C+ for a 78 or 79, C- for a 70 or 71).

Finally, remember that your grade is a measure of your performance and not whether I like you, how smart you are, how busy you were during the semester, etc., etc. Save yourself time wasted in groveling for points.

Attendance, classroom behavior, and life:

I will call attendance for the first few sessions so that I can connect names with faces. I don�t record daily attendance because I assume that you are adults, and will only miss class when absolutely necessary. If you skip class then you will likely do miserably or fail tests. This is no joke. I make up the tests based on what happened in class. I test in detail on what I think the class should know. If you skip class and fail tests then I will have no sympathy.

I will record attendance some variable number of times during the semester. If you are there 3/4 of the time or more then you will get a Woody Allen Award of a point on your final grade. (Woody Allen said, "Ninety percent of success is just showing up on time.")

Please, Please, Please ask questions. Don�t let the moment of confusion pass by. Don�t worry about the rest of the class, your job is to make sure that you understand.
