Ch 2: Research Methods for Human Development

About This Chapter

Go through these lessons to gain insight into the various research methods used for analyzing human development. Discover the processes used to gather experimental data, the ethics of psychological experiments, and more.

Research Methods for Human Development - Chapter Summary

Psychologists examining human development can only validate their theories by gathering and analyzing data, and they can do so by using any number of research methods. In these lessons, you'll receive a broad overview of the most common types of research strategies and data collection methodologies currently used by psychologists and other scientists. Our instructors are experts in their fields, so they know all the details concerning these research methods. More importantly, you can be certain that the information they present is accurate and up-to-date. Furthermore, since we keep our lessons short and focused, you always receive the most relevant and meaningful information. As you go through this chapter, you'll get assistance with the following:

  • Detailing procedures for case studies, interviews, and surveys
  • Understanding applications for the true experimental research design
  • Analyzing causation vs. correlation
  • Defining and explaining the uses of various research designs
  • Discussing research related to the cohort effect
  • Assessing connections between generalizability, sample, and population
  • Examining the role of ethics in psychological experiments

7 Lessons in Chapter 2: Research Methods for Human Development
Surveys, Interviews, and Case Studies

1. Surveys, Interviews, and Case Studies

Researchers often have to decide how to collect data for their research. Should they ask people questions or observe them directly? This lesson will differentiate between three methods of data collection: surveys, interviews, and case studies.

The True Experimental Research Design

2. The True Experimental Research Design

You need to set up a true experiment to test a hypothesis and demonstrate a cause and effect relationship. This lesson will teach you how this is accomplished and when you are forced to use other research designs.

Correlation vs. Causation: Differences & Definition

3. Correlation vs. Causation: Differences & Definition

When conducting experiments and analyzing data, many people often confuse the concepts of correlation and causation. In this lesson, you will learn the differences between the two and how to identify one over the other.

Research Designs: Quasi-Experimental, Case Studies & Correlational Research Designs

4. Research Designs: Quasi-Experimental, Case Studies & Correlational Research Designs

The true experiment is not the only way to conduct research. This lesson will help you understand the use of quasi-experimental research designs, case studies, and correlational research.

Cohort Effect: Definition & Research

5. Cohort Effect: Definition & Research

The cohort effect can have a big influence on how you see the world and a bigger influence for those seeking to understand behavior. Through this lesson, you'll learn how to define the cohort effect and explore why it's significant through some examples.

The Relationship Between Population, Sample & Generalizability

6. The Relationship Between Population, Sample & Generalizability

Researchers try their best to gather a sample that represents their population. But why is this important? In this lesson, we'll look at the relationship between population, sample, and generalizability in research.

Ethics of Psychological Experiments

7. Ethics of Psychological Experiments

What are the ethical principles of psychological research? In this lesson, you'll take a look at the careful considerations a psychologist must make with respect to her participants when she designs a test.
