2. Abnormal Behaviour
• Abnormal Psychology is the
branch of Psychology that
studies unusual patterns of
behaviour, emotion and
thought, which may not be
understood as precipitating a
mental disorder.
• The scope of Abnormal
Psychology is to study
people’s emotional,
cognitive, and/or
behavioural problems.
• It studies the atypical or
abnormal members of the
society who fall outside of
the most common
parameters.

3. What is behaviour?
• Most people use the word
‘behaviour’ to mean conduct.
• Behaviour is anything that a
person does.
• In psychology, behaviour is
regarded as any observable
activity by human being.
• Most human behaviour results
from a combination of factors
such as culture, attitudes,
emotions, values, ethics,
authority, rapport, persuasion,
coercion and genetics.

4. Principles of
Human
Behaviour
Almost all human behaviour is learned.
All behaviours occur for a reason.
No behaviours occur “out of blue.”
Behaviours continue to occur because
they are effective.
Behaviours stop occurring when they are
ineffective.
