Methods
of Psychology
Psychology
is a social science that focuses on an individual’s mind. It is considered a
soft science for drawing conclusions instead of finding certainty. Psychology
is still an experimental science no matter if it is a soft one. Therefore it
must follow the steps of scientific research. There are a variety of methods
used by psychologists to study mind and behavior. Many of these methods differ
in great amounts but they still use similar steps to apply these methods. These
steps are what form scientific research.
There are
seven steps to scientific research and the first one is coming up with a
research question. An example is why are Siamese fighting fish so aggressive?
Aggressiveness is a psychological construct which means that it is
present but cannot be measured. The next step is forming a hypothesis. A hypothesis
is an educated guess which can be tested by research. An example is, “If
fighting fish are aggressive, then they will attack each other.” Testing the
hypothesis is very important in this process. No matter how good or convincing
a hypothesis sounds, it cannot be verified or proved correct if there are no
tests that prove it correct. A way to test the fish hypothesis is to place a
mirror in front of the fighting fish and see if it attacks its own reflection.
Now scientists look at their results and think about what they meant. This step
is analyzing the results. In the experiment the reaction of the fish had to be
analyzed. Based on this conclusions were drawn, the fish was in a defensive
position. Finally the experiment must be replicated, meaning that it
must be repeated and show the same results for it to be verified. In this case
the testing with the fish would have to be repeated or furthered. Two fish
could be placed in the same bowl and see if they attack each other or not.

A very
popular way of gathering information is the survey method. In a survey people
are asked to answer a series of questions on a subject. It is a very effective
way to gather information from the general public and it is also a quick way of
getting information. A problem with surveys is that a person may or may not be
completely honest when answering the questions. The people that are being asked
are part of the target population which is the group that researchers
want to study. It is impossible to interview every single person in the target
population so they ask a sample which is the group of individuals they
are asking. There are problems that come with surveys. One of them is
generalizing results. Researchers cannot draw conclusions on preferences of all
people if they only study or ask a group of people. Of course it would be
unpractical or impossible to ask all people so researchers must be careful when
displaying their results. Another problem is volunteer bias which is
that the volunteers participating may have a different outlook than people who
do not volunteer for research.
The six
methods of observation are more research tools that can be used by
professionals. One of them is the testing method which is several types of
tests (intelligence, personality, etc) which are used to determine certain
behavior, abilities, traits, etc. The case study method is a very popular method among researchers. A
case study is an investigation of a certain group or individual. Case studies are based on interviews which
may affect the results because of dishonesty of the subjects or because
individuals cannot remember certain details. The longitudinal method is
in which researchers select a group or individual and study them for a long
period of time, many of these studies last years. This is the disadvantage to
this method, it is very time consuming. The opposite of the longitudinal method
is the cross sectional method. In this method instead of studying individuals
over a period of years, researchers study samples of different age groups. The
disadvantage to this is that individuals differ in many different other than
age. Researchers study people or animals in their natural habitat with the naturalistic
observation method. This method allows researchers to observe how people or
animals act in their natural life or habitat, the problem is that they have no
control over the setting. This method has an opposite which is the
laboratory observation method. Here the environment in which subjects or
animals are being observed in is artificial. Its benefit is that the researcher
has absolute control of the setting but no artificial setting will never be the
same as a natural one. To analyze these
observations correlations are used. This is a measurement of how one
thing is related to another. Correlations can be positive or negative
correlations. A positive correlation
is the need for achievement and salaries. As one goes up, the other goes up as
well. A negative correlation is stress and health. As one goes up, the other
goes down.
An experiment
is when subjects receive a treatment and researchers observe how this
treatment affects their behavior. Participants being introduced to a new drug
are an example. Experiments have variables which are factors that
change. The independent variable is the factor that is manipulated to
determine its effect, while the dependent variable depends on the
independent variable. In the tested
groups there needs to be an experimental group to actually test the
treatment and the control group for comparison.
Ethics
play a big part in psychology. There is a standard set of ethics that psychologists
follow to protect the dignity of the individual. When dealing with people,
psychologists treat records and clients with confidentiality because of
people’s right to privacy. This may be broken if the individual reveals plans
to harm others or him/herself. Informed consent is when people agree to
participate in research and are fully aware of the conditions. Sometimes though
an experiment cannot run without deceiving the subjects, for example in some
drug experiments subjects can be told that they are taking an actual drug but
they are actually receiving fake pills or vice versa.
As a
science, psychology runs many experiments by many different methods. Something
is discovered everyday by simply asking a question and then taking the right steps
to find the answer. The first steps are always the universal scientific method
but there are many ways to research, observe and test these questions. Psychology is not a science like biology or
physics but it tests, verifies or falsifies hypothesis and theories just like
any other science.
