Typical behaviour is activity that is consistent with how someone usually behaves.
Atypical behaviour is activity that's unusual or unnatural according to how someone usually behaves.
It's important to consider social norms, personal distress, culutural perspectives, maldaptive behaviour, and statistical rarity when debating if someone is typical or atypical.
Cultural perspectives and norms enable different cultural contexts to be taken into account but are limited as in multicultural society, different cultural norms can influence behaviour.
Statistical rarity provides and objective perspective, allowing for more accurate ways to categorise behaviours. However, not all are negative which makes it less helpful.
Personal distress and maldaptive behaviour consider consequences of behaviour but what is considered maldaptive can be objective.
Nowadays, normal is usual or ideal.
Normality is the state of having thoughts, feelings and behaviours that are considered common and acceptable.
Abnormality is the state of deviating from the norm, usually in an undesirable way.
