Lecture 1 :
An Interpersonal Theory Perspective of Normal and Abnormal Behaviour
How is abnormal behaviour defined?
What are the links between abnormal and normal behaviour?
How perpetuates abnormal behaviour?
How do you treat abnormal behaviour?
A theory about personality and social interaction
forces at play that occur when we interact with people
Theory of personality : describes consistent, stable differences
Theory of social interaction : describes forces at play that leads us to engage in give and take when
interacting with people
There are 2 unrelated dimensions
y-axis : dominance (status, control), submissive on other side x-axis : friendliness (warmth,
love), hostile on other side
The segments are fuzzy set (meaning that the boundaries are not so clear cut with peoples personalities)
Related to the big five personality factors
: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism
extraversion and agreeableness fit with the Interpersonal Theory Personalities
agreeableness goes between friendly and submissive, unagreeableness goes between dominant
and hostile. Extraversion goes between dominant and friendly, and introversion goes between
hostile and submissive
ex. Bill : warm person, Bob : grouchy
personality : is stable, bill is consistently warm, bob is consistently cold
social interaction : how some acts to bill compares differently to how to act toward bob.
Responsiveness and interpersonal behaviour depends on who you are acting towards
Interpersonal Circle / Circumplex As the trait moves out to the outer layer the trait becomes more stronger/intense.
Traits 45 degrees from each other are unrelated. Those 90 degrees are the opposite of each other
Difficult Styles and Psychopathology
This are located on the outside of the circumplex (ex. Extreme behaviours of hostile). These
people are rigid with their personalities and do not change that much when they interact with
different people (compared to normal people who do)
Tendency to evoke similar behaviour on friendliness axis
ex. Friendliness should pull friendliness from someone else, Hostile should pull hostile from
Tendency to evoke opposite behaviour on the dominance axis
ex. Dominance should pull submission, submission should pull dominance from someone else
Types of Complementarity
Complementarity behaviours : pull opposite behaviours on dominance axis, and similar behaviours on
