  3. There are four basic types of eye movements: saccades, smooth pursuit movements, vergence movements, and vestibulo-ocular movements. The functions of each type of eye movement are introduced here; in subsequent sections, the neural circuitry responsible for three of these types of movements is presented in more detail (see Chapters 14 and 19 for further discussion of neural circuitry ...

  4. The method of science is a pathway that involves several steps. Scientists themselves might organize the pathway in slightly different ways, but scientists would agree that what is presented here is the scientific method. The scientific method is based upon evidence rather than belief. This distinguishes science from faith.

  7. A hypothesis is a tentative, testable answer to a scientific question. Once a scientist has a scientific question she is interested in, the scientist reads up to find out what is already known on the topic. Then she uses that information to form a tentative answer to her scientific question. Sometimes people refer to the tentative answer as "an ...
