Illusions are not 'magic.' Virtually all of them have scientific explanations based on how our senses work and how our brains interpret sensation. Those that are not understood are simply not understood YET. As you explore some of these links, keep asking yourself how these effects might be understood scientifically.

Exploratorium

Del Mar Fans & Lighting have some interesting pages that explore visual effects

Psychology of Perception

Class Times: TU TH 9.30 - 10.45 am

Offered: on occasion; next offering is Spring 2005

Psychology 120 reviews selected theories of perception as well as certain philosophical questions which bear upon such theories and experimental findings. The development of perceptual processes and personality aspects involved in perceptual processes (e.g., cognitive styles) will also be covered. Thus, periodically, we will deal with questions such as: do the contents of our minds determine what we perceive, or does how and what we perceive determine the contents of our minds?

The course will cover basic scientific findings in perception (e.g., basis of colour vision, audition, the tactile & kinesthetic senses, the chemical senses; phenomena such as categorical perception; techniques of psychophysics). This is necessary because not all of you will have been exposed to Perception as a topic in PSY 3, and because an understanding of the basic perceptual processes (and techniques for understanding them) forms a solid foundation for understanding how humans view the environments in which they function. Because this is a ‘pilot' course for next year's ‘Art and Technology' theme, in every facet of the course, even in discussing basic scientific findings, two themes will be elaborated. I suggest that your term project address one of these themes.

First, it is clear that any detailed understanding of art and aesthetic appreciation must rely on knowledge drawn from studies of the human perceptual systems. For example, an understanding of the perceptual bases of illusion, perspective and complementarity of colours enhances our appreciation of visual art.

Second, throughout the course, the links between ‘fact' and method will be educed. Today's discipline avails itself of techniques adapted from neuroscience, biochemistry, computer science, scaling theory, cognition, cultural studies, and personality. Thus, through this course you will be able to appreciate the interplay amongst art, science and technology, and the human mediator. We will often focus on the relationship between art and the knowledge we have gained about perception.

Responsibilities of the students - Please bring the text to class each day, unless told not to. We will be referring to specific figures and tables in the book. The class meets for just under 3 hours a week. In addition, students are expected to spend a significant amount of time doing their projects, preparing for class, and meeting with their instructor on occasion for individual conferences. Therefore:

1. You are responsible to the group to be at all the class meetings and on time. Attendance will be taken periodically. If you are missed more than 4 times during the taking of attendance, you will given an ‘F' or ‘UW' for the class.

2. Complete all the work for the course on time. One or more ‘assignments' is due each week. Not all assignments are individually graded (see below), but all are necessary to help you learn or for me to know what is going on (e.g., 1st journal on ‘The role of art in my life').

3. Participate in class discussion and take notes in class no matter who is speaking

4. If you are unclear about anything, ASK!

5. Work independently during examinations.

6. Write in your own words at all times, but clearly note sources of information.

7. When asked to submit evaluations of other students' drafts, etc., be prompt, thoughtful & constructive.

Requirements -
Because this course uses a lot of internet demonstrations and tutorials, all students should be able to use a web browser and download plugins. Students who first registered at LIU in Fall 2002 or later are required to provide evidence that they have sat the Core Computer Literacy Requirement examination; otherwise, they will receive an 'Incomplete' until such evidence is provided.

Please note that no ‘Incompletes' will be given without an appropriate excuse. Missing graded assignments/quizzes will be computed as zero (0).
