APPROACH mental processes (EG. Thoughts, perceptions, attention)
affect behaviour
BECK proposed that there were three kinds of negative
thinking that contributed to becoming depressed:
negative views of the world, the future and the self
NEGATIVE TRIAD
Such negative views lead a person to interpret their
experiences in a negative way and so make them more
vulnerable to depression
ELLIS proposed that depression occurs when an
activating event (A) triggers an irrational belief (B)
ABC MODEL which in turn produces a consequence (C) (IE. An
emotional response like depression)
The key to this process is the irrational belief

Definitions of Abnormality
Psychopathology = the study of psychological disorders
o How we identify when someone is psychologically unwell
o How do we determine if their behaviour differs from what we consider normal
and at what point should that person be classified as ‘abnormal’
, STATISTICAL INFREQUENCY
Occurs when an individual has a less common characteristic, for example being more
depressed or less intelligent than most of the population.
The most obvious way to define anything as ‘normal’ or ‘abnormal’ is according to the
number of times we observe it – this is called STATISTICS
According to the Statistical infrequency definition, a behaviour is seen as abnormal if it
is statistically uncommon or not seen very often.
Therefore, abnormality is determined by looking at the distribution of a particular
behaviour.
A common example is that of IQ and intellectual disability disorder
o The average IQ is approximately 100
o 65% of the population have an IQ in the region of 85 to 115.
o Furthermore, 95% of the population have an IQ in the region of 70 to 130.
o However, a small percentage of the population have an IQ below 70 (known as
intellectual disability disorder) or above 130 and these people are statistically
uncommon and consequently
Therefore, they would be classified as abnormal according to this
definition.
A normal distribution curve can be used to represent the
proportions of the population who share a
particular characteristic….
