Replication Crisis Flashcards
(20 cards)
What is Replication?
Being able to repeat a scientific study and get the same results.
What is the main problem with replication in psychology?
Many published studies do not replicate.
What does the failure of ‘cold fusion’ demonstrate?
Non-replication happens in other areas of science too.
A researcher uses the same hypothesis, the same materials and procedure, and the same type of participants as a previous study. The new researcher’s study would be considered ______.
An exact replication.
A study finds that people holding warm drinks are seen as being “warmer” during conversations. A second researcher tests the same hypothesis by using gloves with hand warmers in them instead of warm drinks. This would be considered ______.
A conceptual replication
Of the findings from prestigious psychology journals reported by the Open Science collaboration project, ______% replicated.
36%
Which area of psychology has the lowest percentage of replications according to the Open Science collaboration project?
Social Psychology
What is the problem with studies that use metaphors as primes?
They provide interesting findings but are hard to replicate.
What condition would be required to do an exact replication of Asch’s famous conformity experiment?
To study only men.
If you tried to replicate Ash’s conformity study but asked participants to judge the size of objects instead of length of lines, what kind of replication would it be?
A conceptual replication
If a replication attempt fails, what does it mean?
Replication results were different than the original experiment
What happens to researchers who have been found to be falsifying their results?
They lose their jobs.
Studies with ______ are less likely to replicate.
Small sample sizes
What is the main solution to the replication crisis?
The results of replication attempts, even failed replications, are being made public.
Why might risky research that may not replicate be good for science?
some risks can help advance science more quickly
If a researcher proposes a bold new idea, what is most important from the perspective of science?
strong evidence to support the idea
Why haven’t more researchers attempted to replicate past research?
Doing original research is more prestigious.
What should researchers do to maximize the chances of their research replicating?
Make sure their sample sizes are large enough
Why is publishing articles based on a single study problematic?
They don’t include conceptual replications like multi-study articles do.
When you read textbooks, when can you be confident that a research finding is correct?
If the textbook reports several studies that support the finding.
