What is Research? - Definition, Purpose & Typical Researchers

1. What is Research? - Definition, Purpose & Typical Researchers

Psychological research helps to shape our society - from the way we raise our children to the way we treat our criminals and military enemies. But what is research and who conducts it? This lesson explores the purposes of research in psychology and the individuals who observe, record, and alter our behavior.

How to Produce High-Quality Research

2. How to Produce High-Quality Research

Psychology is a science that requires high quality research due to the inherent complexity of human thoughts, behaviors and emotions. One way to go about producing high quality research is to follow certain guidelines that all true sciences follow.

Nonscientific and Scientific Research: Definitions and Differences

3. Nonscientific and Scientific Research: Definitions and Differences

Explore the way people 'know' information without using a scientific methodology. Have you ever fallen for nonscientific research and then presented it as fact?

What Is the Scientific Method in Psychology? - Definition, Characteristics & Steps

4. What Is the Scientific Method in Psychology? - Definition, Characteristics & Steps

How might someone apply the scientific method to psychological research? We will review the steps of the scientific method and how they applied to one of the most famous psychological studies ever conducted.

Applying the Scientific Model to the Decision-Making Process

5. Applying the Scientific Model to the Decision-Making Process

You've conducted the research and compiled it all together. Now what? What good is 300 pages of research if it is too complex to convey? You can turn it into a model and teach others, but be wary of the pitfalls.

Psychological Research Tools: Observation, Measurement & Experimentation

6. Psychological Research Tools: Observation, Measurement & Experimentation

What are the primary ways a psychologist goes about conducting research? In this lesson, we will look at the three main ways a researcher can go about learning something, as well as some of the more famous psychological research that has used these techniques.

Non-Experimental and Experimental Research: Differences, Advantages & Disadvantages

7. Non-Experimental and Experimental Research: Differences, Advantages & Disadvantages

How is a non-experimental design scientific? We will look at what it means to use experimental and non-experimental designs in the course of psychological research. We will also look at some classic examples of different types of research.

Research Methodologies: Quantitative, Qualitative & Mixed Method

8. Research Methodologies: Quantitative, Qualitative & Mixed Method

While there are many ways to conduct an experiment in psychology, there are only so many ways you can describe it. In this lesson, we will discuss the differences, strengths, and weaknesses of the qualitative, quantitative, and mixed methods.

Basic Research and Applied Research: Definitions and Differences

9. Basic Research and Applied Research: Definitions and Differences

In this lesson, we look at the difference between basic and applied psychological research and discover why there is a separation. Through examples, we'll answer the questions, 'What is the purpose of research if it doesn't apply to the real world?' and 'How are the two interrelated?'

Purposes of Research: Exploratory, Descriptive & Explanatory

10. Purposes of Research: Exploratory, Descriptive & Explanatory

There is a parallel between how people come to understand something and the process of researching an idea. This lesson explores the purposes of research as well as three approaches to research in psychology: exploratory, descriptive, and explanatory.

Types of Research Designs in Psychology

11. Types of Research Designs in Psychology

What are the three main research designs, and what are their advantages and disadvantages? In this lesson, you'll explore the different goals behind descriptive, correlational and experimental research designs.
