Can experiments in psychology be repeated?
Another big project has found that only half of studies can be repeated. And this time, the usual explanations fall flat. Over the past few years, an international team of almost 200 psychologists has been trying to repeat a set of previously published experiments from its field, to see if it can get the same results.
Is psychology suffering from a replication crisis?
Psychology has recently been viewed as facing a replication crisis because efforts to replicate past study findings frequently do not show the same result. Often, the first study showed a statistically significant result but the replication does not.
Why do replications fail?
Our results suggest that many of the studies failed to replicate because it was difficult to recreate, in another time and place, the exact same conditions as those of the original study. Our hypothesis was that certain topics would be more sensitive to context than others.
What is a hypothetical experiment?
A thought experiment is a hypothetical situation in which a hypothesis, theory, or principle is laid out for the purpose of thinking through its consequences.
What is file drawer problem?
the fact that a large proportion of all studies actually conducted are not available for review because they remain unpublished in “file drawers,” having failed to obtain positive results.
Why are some of the famous psychology experiments not repeated?
Though some could not be repeated today due to breaches in ethical boundaries, that does not diminish the significance of their findings. Some of these important findings include a greater awareness of depression and its symptoms, how people learn behaviors through the process of association and how individuals conform to a group.
Where can I find ideas for an experiment?
Your psychology textbooks are another excellent source you can turn to for experiment ideas. Choose the chapters or sections that you find particularly interesting—perhaps it’s a chapter on social psychology or a section on child development. Start by browsing the experiments discussed in your book.
Is it possible to replicate an experiment in psychology?
You might not be able to replicate an experiment exactly, but you can use well-known studies as a basis for inspiration. If you have made a good effort to come up with an idea on your own but you’re still feeling stumped, it might help to talk to your instructor.
Do you have to do your own experiments in psychology?
Experimental methods courses sometimes require students to design and perform their own psychology experiments, but finding a good idea can be difficult. Start your search early and make sure you have the time you need for background research as well as to design and perform your experiment.
