Psychology can be a tricky field and this is why there are many types of research psychology that are used there. You see, there are many things that have to be researched on when it comes to psychology. This is why it is very important that everyone gets to know the many types of research psychology as to be able to identify which ones are best to use in certain scenarios.
The simple experiment types of research psychology are the basic ones. They are the research methods that are used to find the different factors involved in a certain cause and effect scenario. There are many different ways to measure the results of these types of research psychology too. But generally, the process of the simple experiment starts from getting a default value, applying the research experiment, and observing the change that will happen to the value.
Correlational studies types of research psychology, on the other hand, are the research methods that are used to find out the relationships that are seen in different variables. As the name implies, this is the method that is used when the variables are correlated with each other, or when they have something in common. There can be two variables and there can be a lot. The goal is to be able to get whether these variables have a positive correlation, negative correlation or no correlation at all.
Longitudinal types of research psychology pertain to the research methods that are used to find out the relationships seen between different variables that are not related to each other. Basically, these types of research psychology use the observational research technique. Over a long period of time the researchers will observe the changes that will occur in a group of people, wherein they will be getting the data from the onset of the research first and many times as the research is ongoing.
The cross sectional types of research psychology are the research methods that compares the data and information of people who have lots of differences but somehow share a certain characteristic. These characteristics can either be ethnicity, social status, educational background, and the like.
Survey are also used and considered as types of research psychology too. As you may already know, surveys pertain to gathering data of individuals who are willing to participate in the research. There are surveys wherein the participants will be asked to choose from a written set of options. There are others, however, that will require the participants to write freely their answers to the set of questions that are presented to them. No matter which methods are used, the goal of the surveys is to be able to gather the data based on the individuality of the participants.
Lastly, the within subjects design types of research psychology are research methods wherein participants will be exposed to different kinds of situations or conditions so as to be able to observe the changes that will happen next. These conditions are the variables in these kinds of studies.
