Exam 14: Replicability, generalization, and the Real World

Cindy decides to conduct a meta-analysis examining the relationship between daily stress and cardiovascular health for her senior psychology research project. -Which of the following is NOT a reason that psychologists especially value meta-analyses?

Which types of claims are always made in generalization mode? Why is this the case?

Dr.Grayson,a health psychologist,conducts a study examining whether people eat more when they are exposed to pictures of food than when they are not exposed to pictures of food.She goes to a fast-food restaurant in downtown Chicago that has pictures of menu items on its menu board and measures the amount of food ordered during the lunch rush (11:30 a.m.-1:30 p.m. )on Tuesday.On Thursday,she does the same thing but at a fast-food restaurant that does not have pictures on their menu board (about two blocks away from the first restaurant).She finds that the restaurant with pictures of food sells more food than the restaurant that does not have pictures. -Dr.Grayson decides to conduct her study again,but in the new study,she studies people at a sit-down restaurant,and she manipulates whether the menu they use at the table has pictures or not.This is known as which of the following?

Which of the following is true of a scientific literature?

Explain why using WEIRD samples tends not to be a problem for researchers operating in the theory-testing mode and why cultural psychologists question this practice.

What is experimental realism? What does this mean for studies conducted in artificial settings (e.g. ,a laboratory)and studies conducted in field settings?

A study conducted in the "real world" is often said to be conducted in:

Which of the following is true of experimental realism?

A researcher in theory-testing mode focuses on ________,while a researcher in generalization mode focuses on ________.

Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cognitive tasks.In his study,he gives half of his participants a glass of water and half of his participants a glass of cola,and then has them attempt to solve 15 math problems.He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand. -Mark decides to conduct a conceptual replication.Which of the following could be in the study to make it this type of replication?

Dr.Tropez conducts a study examining the relationship between exposure to religion in popular media and religiosity (defined as "the belief in and worship of a superhuman controlling power,especially a personal God or gods").In his study,he randomly samples a group of 113 participants from his local community college.He generates a list of movies with religious themes (Year One,Dogma,Passion of the Christ)and asks participants to indicate how many they have seen.He then measures religiosity by asking participants how many times they have attended a house of worship (e.g. ,church,temple,synagogue,mosque)in the past year.He finds that having seen a higher number of religious-themed films is positively correlated with religious attendance. -Provide an example of each of the following for Dr.Tropez's original study: a direct replication,a conceptual replication,and a replication with extension.

Mark conducts a study for his research methods class to determine if consuming caffeine causes people to perform better on cognitive tasks.In his study,he gives half of his participants a glass of water and half of his participants a glass of cola,and then has them attempt to solve 15 math problems.He finds that people who drink caffeine beforehand solve more math problems than those who drink water beforehand. -Mark decides to conduct the exact same study again to ensure that he can find the same difference between the groups a second time.This study is known as a:
