Today we will first introduce the course and some basic methodological issues in psychology. We will then will be looking at a part of our life that we have little access to, sleeping. We will, in looking at this issue, also get some exposure to a range of isssues, methodologies and approaches that are used in psychology. One of the major questions we will ask is whether and why we need to sleep. Slides are at sleep-dreaming slides.
The major topics we will be discussing include:

• Defining sleep
• Sleep as a behavior
• The behavior and role of the brain in the control of sleep
• Theories of sleeping (why we sleep)
• The necessity of sleep--do we need to do it?
