Interactionist approach
Summary

3. Theory 1 – Hollander (1971) ‘Personality as a Layered Structure’
Inner psychological core – (not affected by the environment). Fairly permanent qualities, e.g. basic beliefs and values reside here (controlling or dictating behaviour – trait approach)
Way we typically or usually respond to certain situations
Role-related behaviours – Typical response may be affected by circumstances. Behaviour will be completely different at different times and in different situations and may well be quite unlike our psychological core (interactionist approach)
Social environment – Affects our role-related behaviours

4. ‘Narrow Band approach’ Personality
TYPE A
Impatient
Intolerance
High levels of stress
TYPE B
Relaxed
Tolerant approach
Lower personal stress

5. ‘Eysenck’s Type Theory’
Stable (reliable and predictable) Extroversion (likes social affiliation) Introversion (avoids social contact) Neurotic (extreme emotions and unreliable)
“People don’t have one type of personality or another, they lie on a scale of traits”
This research led to the construction of the EPQ and EPI (Eysenck’s Personality Inventory)

6. Extroversion – Introversion
Eysenck regarded personality as largely resulting from inherited (innate) tendencies.
He measured these inherited characteristics through a Personality Inventory (EPI, 1964), and personality questionnaire (1975)
He used factor analysis to identify general trends.
Therefore identifying 2 major personality dimensions on a continuum
Extroversion – Introversion
Stable - Neurotic

7. Personality continuums
(Extroversion – Introversion). This dimension linked to a person’s Reticular Activating System (RAS). Related to how social or unsocial a person appeared to be.
(Stable – Neurotic). This linked to a person’s autonomic nervous system. Referred to the levels of nervousness and anxiety that a person was susceptible to.

8. It was claimed that extroverts were more likely to take part in sport and be more successful, that they prefer team games and that:
Extroverts cope better in competitive and highly charged, stressful situations
Extroverts cope better in the presence of distracting stimuli (e.g. audience, noise)
Extroverts can cope with pain more easily then introverts

9. Cattell’s theory (1965)
Adopted a trait approach but argued you needed more than 2 dimensions to create a full picture of a person’s personality.
Cattell’s 16 point personality questionnaire would identify certain common traits (possessed by all), and unique traits (possessed by some).
Therefore personality was more dynamic and could fluctuate according to the situation and the environment.

10. Evaluation of ‘trait theories’
Did not recognise the specific effects of different environmental situations
Traits are seen as poor predictors of behaviour. Although people have certain core tendencies, or are disposed to act in certain ways, these behaviours are not general but specific to certain situations
Therefore interactionist approaches would be more efficient in predicting behaviour

11. Interactionist approach
B=f(PE)
B=Behaviour
F=Function
P=Personality Trait
E=Environment

12. Summary
Hollander (1971) believes personality is subject to both trait and interactionist approaches.
The narrow band approach believes there are only 2 categories of personality
Eysenck’s type theory - “People don’t have one type of personality or another, they lie on a scale of traits”
Cattell’s 16 point personality questionnaire would identify certain common traits (possessed by all), and unique traits (possessed by some).
