De eerste vragen gaan over het artikel:
Brunell, A.B., Fisher, T.D. (2014). Using the bogus pipeline to investigate grandiose narcissism.Journal of Experimental Social Psychology, 55, 37-42. https://doi.org/10.1016/j.jesp.2014.05.015
1. What is the research question of Brunell and Fisher (2014)?
To what extent are grandiose narcissism and other narcissism-related constructs sensitive to bias in reporting?
2. In the article, an experimental manipulation is used.
a. Please explain, in your own words,what a bogus pipeline is.
The bogus pipeline is a technique used by social psychologists to reduce socially desirable answers. Participants are linked to a device that the researchers tell them is a lie detector. As a result, participants have the feeling that they are being checked to see whether they are responding truthfully. It is assumed that this will actually motivate participants to answer truthfully.
b. Describe, in your own words, what the differences are between the experimental conditions in this study.
The idea behind this is that by using the bogus pipeline technique, amongst other things, the measurement of social constructs becomes more valid. Giving socially desirable answers is a systematic error that affects validity.
Bogus pipeline condition: Participants were told that they would be linked to a lie detector during the experiment. Participants completed the questionnaires while they were linked to the bogus pipeline.
Anonymous condition: Participants in this condition were not linked to a lie detector. Participants filled in the questionnaires in a private setting.
Exposure threat condition: Participants in this condition were not linked to a lie detector. Participants completed the questionnaires, with a survey assistant in the room. This research assistant informed the participants that he/she would pick up the questionnaire afterwards. In all conditions, the participants submitted the questionnaires in a closed box.
De volgende vragen van de voorbereidende opdracht gaan over replicatie, assumpties en type I fouten.
Replication Explanation
Direct replication | In direct replication researchers repeat an original study as closely as they can to see whether the effect is the same in the newly collected data. |
Conceptual replication | In a conceptual replication researchers explore the same research question but use different procedures. The conceptual variables in the study are the same, but the procedures for operationalizing the variables are different. |
Replication-plus- extension | In a replication-plus-extension study, researchers replicate their original experiment and add variables to test additional questions. For example, adding an additional experimental condition or adding an additional (in)dependent variable. |
Assumptions ANOVA
Assumptions ANCOVA
Type I error
| Population: difference | Population: no difference |
Conclusion NHST: reject H0 | Correct decision: power | Type I error |
Conclusion NHST: do not reject H0 | Type II error | Correct decision |
Alpha = chance that you falsely reject your null hypothesis (type I error).
Beta = chance that you falsely reject your alternative hypothesis.
Power = chance that you correct reject the null hypothesis.
If you do one analysis the probability of making a type I error = alpha.
Multiple analysis: probability of making a type I error > alpha.
Experiment wise error rate: aew = 1 – (1 – apc)c
c = the amount of comparisons
