Experimental Methods and Design

Start with an example

Begin with the note Experimental Method. It uses an energy drink experiment to show how an aim can develop from a theory. As you read, identify the theory and the aim in the example. This gives you a starting point for the terms used in the other resources.

Next, open Psychology: Experiments. One mind map with this title looks at variables that may need controlling, including aspects of the environment such as light, time of day and background noise. Use it to think about what else might affect behavior during an experiment.

Explore methods and designs

The mind map The Experimental Method brings together the scientific method and ethical issues. It lists issues including consent, deception, risk of harm, confidentiality and privacy. Use these headings to organize your notes as you study.

For experimental designs, the flashcards Experimental Designs, Control + Sampling cover independent groups and repeated measures, including strengths and weaknesses. The flashcards on types of experiments ask about advantages and disadvantages of lab and field experiments. Compare the designs and experiment types as you work through them.

Use maps and quizzes together

After studying a map, try the quiz Types of Experiment. Return to the maps and flashcards when you want to look at a term or comparison again. You can also use the flashcards to practice recalling points without looking at the maps.

These resources sit in the Experimental Methods and Design section of the Research Methods and Ethics unit in Psychology. The maps connect experimental methods with investigation design, ethical issues and scientific processes within that unit.
