My Flashcards

Definition

Meaning

The loss of individual identity and self-awareness that can occur when a person is part of a group, often leading to reduced inhibitions and a weakening of personal responsibility for one's actions.

In social psychology, deindividuation is a psychological state where an individual's self-evaluation and concern for social assessment are diminished, often due to anonymity, group immersion, and heightened arousal. It's a key concept in explaining collective behaviours like mob violence, riots, or online trolling.

Linguistics

Semantic Notes

Strongly associated with negative social phenomena (e.g., mob violence, hooliganism). It is a process, not a permanent state. Often contrasted with 'individualisation' or 'self-awareness'.

Learning

Memory Aids

Mnemonic

Think of a crowd wearing identical masks at a carnival (DE-IN-DIVID-UATION): the individual face (INDIVIDual) is taken away (DE-), leading to a uniform 'ation' or state.

Conceptual Metaphor

THE INDIVIDUAL IS DISSOLVED/DILUTED IN THE GROUP (like a drop of ink in water). THE GROUP IS A MASK/CLOAK (that hides the individual).

Watch out

Common Pitfalls

Translation Traps (for Russian speakers)

  • Avoid direct calque 'деиндивидуализация'. The standard Russian equivalent is 'деиндивидуализация', but the more common conceptual term is 'утрата индивидуальности в группе' or the specific psychological term 'деиндивидуация'.

Common Mistakes

  • Misspelling: 'deindividualization' (AmE spelling is also '-isation').
  • Confusing it with 'dehumanisation'.
  • Using it as a synonym for simple 'anonymity'.

Frequently Asked Questions

While most research links it to antisocial behaviour, some studies suggest it can also increase prosocial acts if the group norms are positive (e.g., anonymous charity donations). However, the core concept is neutral—a loss of individual identity—which is typically associated with negative outcomes.
