Placebo effect
A medical effect based solely on the power of suggestion.
An example would be taking a plain pill, thinking it was a pain reliever, and unknowingly convincing yourself the pain went away, even though that’s not the case.
Placebo
An imitation of a drug or remedy that is designed to trick the subject into believing they’re receiving the genuine treatment.
A sugar pill that acts like the real medication, but has no effect.
Experimenter effect
Tendency of the experimenter’s expectations for a study to unintentionally influence the results of the study.
For example, taking a survey for the amount of junk food you eat. A person may not want to share the real amount so they give an amount they think is ok.
Single-blind study
Study in which the subjects do not know if they are in the experimental or the control group.
For example, having everyone in one group and then have them randomly divide into two. No one knows who the experimenter has as the experimental or the control group.
Double-blind study
Study in which neither the experimenter nor the subjects know if the subjects are in the experimental or the control group.
This would be having two groups, neither know which they are, and the experimenter not knowing which they are.
Stereotype
A set of characteristics that people believe is shared by all members of a particular social category; a concept held about a person or group of people that is based on superficial, irrelevant characteristics.
For example, it would be stereotypical to say that kids play on playgrounds, unlike adults don’t.
Observer bias
Tendency of observers to see what they expect to see.
For example, if an observer had a relation with one of the subjects they maybe more likely to see/say what they want about them than what did happen.
