Hello everyone. Let’s begin this section by talking about some measurement
techniques that we use within Physiological Psychology. That is what we
call the metric system. The metric system is not only used in Physiological
Psychology, it’s used in neurochemistry and many, many other scientific
disciplines as well. So, what is the metric system? What are the numerics
that go along with it? Well let’s show these on page two. As you can see,
there’s a variety of different multiples and sub-multiples of 10, which is
basically what makes up the metric system. You’ll notice there are also
prefixes that are associated with those multiples and sub-multiples as well
as different symbols. What I’d like you to do is make sure that you have
memorized these multiples, sub-multiples, and the prefixes that go with
that. So for example, you should know that 10 to the minus 3 relates to
Milli, or 10 to the minus 9 relates to nano. These are going to be
extremely important things that we’re going to have to know when we’re
talking about things such as peptides and neurotransmitters.
Let’s move on and look into some common multiples that we
use and combinations that we use in Physiological Psychology and are listed
on page three. As you can see here, we have a variety of different ones.
We have milliamps and millimeters, we have nanometers, pekometers, pekograms,
and on and on. Each of these are going to be related to things that we are
going to be covering in Physiological Psychology.
Today, in Physiological Psychology, we primarily
concentrate on micro, nano and piko in relation to things that we’re going
to either be measuring within a distance or as weight. For example, we talk
about pekograms as part of the physiological mechanism of looking at weights
of particular molecules. Now that we’ve covered a little bit about
measurement, what I’d like to do next is begin to cover some materials in
relation to planes of orientation. We will begin covering that in the next
section. So until that time, I hope you have yourself a great day.
