Double blind conditions
A placebo is a medication that elicits a positive emotional response in an experimental subject?
Actually, a placebo is a substance or treatment with no therapeutic effect that is used as a control in medical research. It allows researchers to isolate the true effects of a treatment by comparing the results from the actual treatment group to those from the placebo group.
The experimental procedure in which both the experimenter and subject are unaware of who is in the experimental and who is in the control group is referred to as the?
Double blind experiment.

What is a double blind crossover study?
I want to know if a medication has the desired effect. I'm going to give half the subjects the 'live' med, and half will get a placebo. The subjects will not know which one they are getting. That's one level of "blind". Studies show that there is a measurable affect based on the fact that the person distributing the med's knows who is getting the med and who is getting the placebo. So I am going to package the med's and give them to the distributing nurse, and the nurse will not know who is getting the med and who is getting the placebo. That is "double blind" model.
What do placebo and nocebo effects have in common?
I think the things they have in common is how many of the things that the placebo and nocbo all are psychological. and the supject can not experance the placebo and novebo with out them knowing or having an idea of what is happaning( or the idea can form in there mind), If you give someone a sugur pill the only effect related to the pacebo effect to happen are all in the mind and what the subject thinks it is.
What is unobtrusive observations?
An unobtrusive observation is when an experimenter simply watches and takes notes of the behavior of the subject in either a natural or laboratory setting WITHOUT any kind of interaction between the experimenter and subject.This is the opposite of an obtrusive observation in which the experimenter DIRECTLY interacts with the subject. For example, in a social environment, the experimenter makes eye contact and smiles at an individual walking by to watch for a response. In an unobtrusive observation, the experimenter would simply watch the way the subject responds to other people but DOES NOT deliberately smile to watch for a response.
What type of experiment is it when only the subject does not know it they are receiving the real treatment of the placebo?
If the experimenters know but the subject does not, it's called a "single blind" study. If the placebo is randomized and neither the subject nor the experimenters know which is the placebo, it's called a "double blind" study.
The group in an experiment that is not exposed to the tested variable is called the group?
An unexposed subject is the "control" for the experiment. The purpose is to establish an idea of what would normally occur outside the testing procedure. Similarly, in human tests, an inactive "placebo" is given to some subjects to verify that the changes occur independently of the psychosomatic (belief-driven) effects. In a "double blind' experiment, the person distributing the medication also does not know whether any particular individual is receiving the actual drug or a placebo. This is hidden in coded form until the results are recorded.
In an experiment a group that receives no treatment is called what?
A group that receives no treatment is called the control group. The control group is there to compare the results between a group that has been exposed to diffent conditions, and one that has not.
Why is it important to have a control group for scientific experiments?
Often, scientific experiments come about because a scientist has a hunch that something may be the case. In these circumstances, it is therefore vitally important to guard against the experimenter's expectations clouding the results, as he or she may have a tendency to see what he or she wants to see. The best way currently known to achieve this is the double-blind control method. Say there are 100 subjects. A chemist prepares 50 genuine pills, and 50 identical-looking pills that do not contain the substance being tested (placebos). He puts them into bottles labelled 1-100, as randomly as possible, taking note of which bottle has a real pill and which a placebo, but he does not show this list to the experimenter. Thus neither the experimenter nor the subject know whether the pill is real or not (double blind). Therefore, when the patient reports the effects and the experimenter does her examination, neither can be influenced by prior expectation. Once the results are in, they are tabulated against the list of who got what, and the true effectiveness can be assessed honestly. With life-preserving drugs, giving a placebo may not be an option, so some of the protocol's protection may have to be sacrificed, say by comparing with the recorded effects of previous drugs that were supposed to do the same thing.
