the idea that people feel less obliged to take action when there are other people present who could do so and are therefore just as responsible for what happens.

the number of items that a person can repeat accurately from a list of digits (letters or numbers) which is read to them only once. Most people can remember about seven, but it is normal for digit memory span to be anywhere between five and nine. Digit memory span is thought to correlate with intelligence.

an approach used in the explanation of behaviour in social situations, where social life is seen as a metaphor for stage performance, with individuals selecting the roles and scripts to be played.

Theories of human motivation which explain why we do things, using the idea that our behaviour is directed towards reducing some inner need. The need then sets up an internal tension, and the desire to reduce this tension forms a pressure to act (the drive) which is only reduced when the need becomes satisfied.
