3: Personality measurement, measures, and judgment Flashcards
What are trait psychologists primarily interested in?
determining the ways in which people are different from each other
Which approach does The trait perspective take?
It takes a quantitative approach, which emphasizes how much a given individual differs from average (statistical and mathematical)
there is a degree of consistency in personality over time, but what is able to change?
the latent trait may remain stable but the manifest behaviour may change over the years
observing changes in behaviour in someone over time does not necessarily mean that his or her personality has changed. It can simply be that the latent trait is now expressed in other behaviours that may be more appropriate given, for example, one’s age.
What is rank order?
If all people show a decrease in a particular trait at the same rate over time, they might still maintain the same rank order relative to each other
Which traits show high test–retest correlations, even with years or decades between measurement occasions?
Traits such as intelligence, emotional reactivity, impulsiveness, shyness and aggression
trait theories share three important assumptions about personality traits, which?
- meaningful individual differences
- stability or consistency over time
- consistency across situations.
How does personality traits relate to situations?
personality traits are average tendencies to behave in certain ways.
For example, if a young man is ‘really conscientious’, he is expected to be conscientious at work, conscientious at school and conscientious during recreation activities
What did Walter Mischel say about traits, situations and behavior? And what is this position callad?
If behaviour differs from situation to situation, then it must be situational differences, rather than underlying personality traits, that determine behaviour.
This position is called situationism
What did Mischel’s debate with trait psychologists made clear?
there are two possible explanations for behaviour, or why people do what they do in any given situation:
○ Behaviour is a function of personality traits, B = f (P).
○ Behaviour is a function of situational forces, B = f (S)
is behavior a function of personality traits or is behavior a function of situational forces?
Both are correct - it depends
people behave differently at funerals than they do at sporting events, illustrating that situational forces direct behaviour in certain ways
Some people, however, are consistently quiet, even at sporting events, whereas other people are talkative and sociable, even at funerals. These examples lend support to the traditional trait position, which stresses that personality determines why people do what they do
What does Funder (2006) personality triad say?
That behaviour is a function of the interaction between personality traits and situational forces
Therefore, it consists of the triad: persons, situations and behaviours
When very specific situations can provoke behaviour that is otherwise out of character for the individual, it is called xxx?
situational specificity
in which a person acts in a specific way under particular circumstances
situations in which nearly all people react in similar ways are called?
strong situations
This could be e.g. funerals
Apart from situational specificity and encountering strong situations, there are three other ways in which personality traits interact with situations, which?
- situational selection, the tendency to choose the situations in which one finds oneself
- personality influences the kinds of situation in which people spend their time. This is also referred to as the person–environment fit.
- situation can affect the person’s personality as well
What is evocation?
the idea that certain personality traits may evoke specific responses from the environment
What is manipulation?
Manipulation is the intentional use of certain tactics to coerce, influence or change others
Individuals differ in the tactics of manipulation they use
Which measurement does the trait approach rely on?
self-report questionnaires
Although trait psychologists can use other measurement methods (e.g. projective techniques, behavioural observation)
What does Carelessness/inattention refer to? (in self-report-measurements)
Some participants filling out a trait questionnaire might not be motivated to answer carefully or truthfully
When is carelessness/inattention often seen?
if questionnaires are too long, the participant may not be reading the questions carefully but is nevertheless providing answers
How could one detect carelessness/inattention in self-report measures?
- A common method for detecting these problems is to embed an infrequency scale within the set of questionnaire items. The infrequency scale contains items that all or almost all people will answer in a particular way. fx “jeg går altid på hænder op af trappen”
- Another technique used to detect carelessness is to include duplicate questions spaced far apart in the questionnaire.
- include reversed questions
- include factual or reasoning questions “how many sides are there in a triangle?”
What is it called when participants have the tendency to choose intermediate or neutral answers?
middle category endorsement
In which way could you minimize middle category endorsement?
by using a forced-choice format.
For example, in this case the researcher may decide to use two alternatives (‘yes’ and ‘no’) instead of three
You could also use a Likert Scale - but here people could also choose a lot of middle answers
Sometimes people are lying when filling out a self-report, what does it mean for a researcher when the answers are rated false negative or false positive?
- The researcher may conclude that a truthful person was faking and reject that person’s data (called a false negative).
- Or they may decide that a person who was faking was actually telling the truth (called a false positive)
What is a Barnum statement?
They are generalities – statements that could apply to anyone.
These are often found in astrology predictions
What does classical test theory assume?
that each observed score (X) consists of a true score (T) and an error component (E). That is, X = T + E. The more one can reduce the error in an assessment, the more closely the observed score will approach the true score
What does response theory (IRT) state?
that the probability that a person will give a certain answer to an item (statement, question, etc.) depends on the characteristics of the person and the item
What is personnel selection?
When employers use personality assessment in the workplace to pick out the “right” candidate for a job
What is integrity tests?
tests that are designed to predict a tendency toward theft or other forms of counterproductive behaviours in work settings
Which tests are often used to select the right candidate for a policejob?
the Minnesota Multiphasic Personality Inventory (MMPI), which primary use is to identify persons with significant psychological problems.
What is the most widely used personality assessment device in business settings?
the Myers–Briggs Type Indicator (MBTI), which provides information about personality by testing for eight fundamental preferences. These eight fundamental preferences reduce to four scores – you are either extraverted or introverted; sensing or intuitive; thinking or feeling; judging or perceiving
Which problems are there with the Myers–Briggs Type Indicator (MBTI)?
- the theory on which it is based – Jung’s theory of psychological types – is not widely endorsed by academic or research-oriented psychologists.
- People don’t come in “types” like a bimodal distribution, instead people are placed normally distributed.
Given the highly negative reviews on the scientific merit of the MBTI, why does it continue to be a hugely popular tool in consulting and career counselling?
□ First, the popularity of the MBTI may reflect the success of the publisher’s marketing campaign.
□ In addition, the test comes with rather simple scoring and interpretation instructions, making it usable and understandable by people without advanced training in personality psychology.
□ Moreover, the interpretations the test offers are readily translated into seemingly sensible predictions about work and interpersonal relations
Shold the Myers–Briggs Type Indicator test be used to select employees?
NO, people are more than what the test indicates and the test does not have a scientific foundation
What is an alternative to the Myers–Briggs Type Indicator test and why?
the Hogan Personality Inventory (HPI)
Because:
1. the HPI is based on the Big Five model, which has been modified specifically for applications to the workplace
- The construction and development of the HPI followed standard statistical procedures, resulting in an inventory with a high level of measurement reliability (mere end 400 validitetsforsøg)
- The test has been able to predict occupational success in a wide variety of job categories
(over 200 different work categories)
