A placebo control group [3] [4] can be used to support a double-blind study, in which some subjects are given an ineffective treatment (in medical studies typically a sugar pill) to minimize differences in the experiences of subjects in the different groups; this is done in a way that ensures no participant in the experiment (subject or ...
The simplest between-group design occurs with two groups; one is generally regarded as the treatment group, which receives the ‘special’ treatment (that is, it is treated with some variable), and the control group, which receives no variable treatment and is used as a reference (prove that any deviation in results from the treatment group ...
A T-group or training group (sometimes also referred to as sensitivity-training group, human relations training group or encounter group) is a form of group training where participants (typically between eight and fifteen people) learn about themselves (and about small group processes in general) through their interaction with each other.

In this case, the treatment is inferred to have no effect when the treatment group and the negative control produce the same results.

If an addict broke the rules, he faced public humiliation, such as being forced to wear a sign around his neck or shave his head. A centerpiece of the treatment was a confrontational form of group therapy that became known as the Game.
