Deindividuation occurs not only in crowds, but also in smaller groups. Psychology Today7— Deperson- so it would seem, humans become disinhibited and be- alization thus transforms individuals into group members have anti-normatively.

Given that most research on deindividuation has used adult samples, it may be worthwhile to investigate whether there is a difference in the rate of conformity to group norms between subjects of different ages in deindividuated situations.

From Revenge to Restoration: Additionally, the researchers showed interest in the intensity of the shock applied, and they told the participants that they would meet the test subject after the experiment and that the participants were individually responsible for what happened to the test subject. In this case, the person does not feel unique in relation to others, causing a propensity to reduce inner restraints.
