Trends lecture 5

What is a personality trait?

A relatively stable pattern of behaviour and experience that differs between people.

Does having a personality trait mean behaving the same way in every situation?

No. People’s states vary across situations even when their overall patterns are relatively stable.

What is a personality taxonomy?

A system for organising and classifying personality descriptions.

What are the Big Five personality traits?

Extraversion, neuroticism, openness/intellect, agreeableness, and conscientiousness.

What is extraversion?

A broad trait associated with sociability, talkativeness, assertiveness, and positive emotionality.

What is neuroticism?

A broad trait associated with anxiety, emotional reactivity, irritability, and negative emotional experiences.

How is emotional stability related to neuroticism?

High emotional stability corresponds to low neuroticism.

What is openness/intellect?

A broad trait associated with curiosity, creativity, imagination, and interest in ideas and new experiences.

What is agreeableness?

A broad trait associated with compassion, cooperation, politeness, and concern for others.

What is conscientiousness?

A broad trait associated with organisation, diligence, self-discipline, and carefulness.

What is a personality facet?

A narrower and more specific characteristic within a broad personality trait.

What are examples of extraversion facets?

Sociability, talkativeness, and assertiveness.

What are examples of conscientiousness facets?

Organisation, self-discipline, and achievement striving.

What did the lecture’s research on psychological scales and the Big Five find?

More than 80% of the scales examined could be located within the Big Five space, often as narrower facets.

Is the Big Five the only useful personality taxonomy?

No. Other useful systems exist, including HEXACO.

What are the six HEXACO traits?

Honesty–Humility, Emotionality, Extraversion, Agreeableness, Conscientiousness, and Openness to Experience.

How does HEXACO differ from the Big Five?

It includes Honesty–Humility and organises some characteristics related to emotionality and agreeableness differently.

What cross-language advantage of HEXACO was mentioned in the lecture?

It has been recovered in more languages than the Big Five in some research.

What does parsimony mean in personality description?

Describing a wide range of personality characteristics using relatively few concepts.

What does comprehensiveness mean in personality description?

Capturing a wide range of information and detail about personality.

What is the bandwidth–fidelity trade-off?

Broad traits cover many behaviours but provide less detail, while narrower traits describe specific tendencies more precisely.

What is bandwidth in the bandwidth–fidelity trade-off?

The breadth of behaviours and experiences covered by a trait.

What is fidelity in the bandwidth–fidelity trade-off?

The precision with which a narrower trait describes a specific tendency.

Why can two people have the same broad agreeableness score but differ?

One may be high in compassion and low in politeness, while the other is moderate in both.

What are the three levels of personality description proposed by McAdams and Pals?

Dispositional traits, characteristic adaptations, and integrative life narratives.

What are dispositional traits?

Broad descriptions of relatively stable patterns of behaviour and experience.

What are characteristic adaptations?

More contextualised goals, values, roles, and other aspects of how a person adapts to life.

What are integrative life narratives?

The stories people construct about who they are and how their experiences fit together.

Why is personality more than the Big Five?

Traits provide broad descriptions but do not fully capture people’s goals, values, roles, and life stories.

What does it mean to view a trait as an input?

The trait is treated as an underlying factor that causes patterns of behaviour and experience.

What is an example of viewing a trait as an input?

“She is talkative because she is extraverted.”

What does it mean to view a trait as an output?

The trait is treated as a summary of patterns in behaviour and experience.

What is an example of viewing a trait as an output?

“She is extraverted because she is generally talkative and sociable.”

What is a latent variable?

An unobserved construct inferred from measured indicators.

What are indicators in a latent-variable personality model?

Measured responses or behaviours used to infer a trait, such as questionnaire responses about talkativeness.

How does a latent-variable model explain correlated personality indicators?

A common underlying trait is modelled as influencing the indicators.

What is an example of a latent-variable explanation of extraversion?

An underlying extraversion factor influences talkativeness, sociability, and assertiveness.

What is a measurement criticism of treating traits as causes?

Questionnaires usually ask people to summarise behaviour and experience rather than directly measuring the underlying cause.

What is the tautology criticism of traits as causes?

If a trait is defined by a behaviour, saying the trait causes that same behaviour may simply repeat the description.

Does the tautology criticism prove that underlying causes do not exist?

No. It shows that a trait label alone does not establish or explain an underlying cause.

Does a well-fitting latent-variable model prove that the trait causes behaviour?

No. The model can describe correlations without by itself establishing the causal explanation.

What is a personality state?

A person’s behaviour or experience at a particular moment or over a short period.

What is the distribution density hypothesis?

The view that personality traits summarise distributions of personality states across time.

What is a distribution of personality states?

A description of how often a person shows different levels of a state across occasions.

What does a trait represent in the distribution density view?

A summary of the person’s typical pattern or central tendency of relevant states.

Can an extraverted person be quiet?

Yes. An extraverted person can be quiet in some situations while tending to show more extraverted states overall.

What method did Fleeson (2001) use to study personality states?

Experience sampling: participants repeatedly reported their recent behaviour and experience.

How many people were in Fleeson’s 2001 experience-sampling study?

46 students.

How often did participants report their states in Fleeson’s study?

Five times per day over 13 days.

What did Fleeson’s study find about personality states?

States varied considerably from moment to moment, while average patterns were relatively stable during the study.

How were trait scores related to state distributions?

Higher scores on a trait were associated with higher average levels of corresponding states.

What is the weather and climate analogy for personality?

States are like weather at a particular moment; traits are like climate, describing longer-term patterns.

What is the dynamic network view of personality?

The view that traits summarise connected patterns of thoughts, feelings, and behaviours.

How can conscientious behaviours be connected in a network?

Being planful may help someone work efficiently, and efficient work may help them complete tasks.

What is an example of a possible neuroticism-related network connection?

Worrying may contribute to difficulty sleeping.

What are interdependencies in a personality network?

Relationships in which behaviours or experiences can influence one another.

What are two proposed sources of stability in a dynamic network?

Interdependencies among network elements and stable influences external to the network.

What are examples of influences external to a personality network?

Genetic and environmental factors that may affect multiple parts of the network.

What does the flock-of-birds analogy illustrate?

Connected elements can form a coordinated pattern without a single leader directing every element.

How do latent-variable and dynamic-network views differ?

The latent-variable view models a common factor influencing indicators; the network view emphasises connections among indicators and shared influences.

Can distribution density and dynamic network views complement each other?

Yes. Distribution density describes patterns of states over time, while network models consider connections among those states.

Why should researchers avoid assuming that one model automatically reveals the true cause?

Different models can describe similar correlations, so causal claims require additional evidence.

What are the ABCs of personality?

Affect, behaviour, and cognition.

What is affect in personality research?

Feelings and emotional experiences.

What is behaviour in personality research?

Observable actions and activities.

What is cognition in personality research?

Thoughts, ideas, interpretations, and other mental experiences.

What did Pytlik Zillig et al. (2002) analyse?

The affective, behavioural, and cognitive content of 476 items from six Big Five inventories.

What type of content was most prominent in neuroticism measures?

Affective content, particularly emotional experiences such as anxiety.

What type of content was prominent in extraversion measures?

Behavioural content, alongside some affective content.

What type of content was prominent in openness/intellect measures?

Cognitive content, including engagement with ideas and aesthetics.

What type of content was prominent in conscientiousness measures?

Behavioural content, such as organisation and diligence.

What kind of content appeared in agreeableness measures?

A mixture of affective, behavioural, and cognitive content.

Do the ABC findings mean each trait contains only one type of content?

No. They describe tendencies in questionnaire content, with variation across traits and measures.

What does “the psychology of the stranger” mean?

The Big Five can provide broad first-impression descriptions of a person we do not yet know well.

What is self–other agreement?

The correspondence between a person’s self-rating and another person’s rating of their personality.

Does self–other agreement necessarily prove accuracy?

No. It shows shared judgments, but neither self-ratings nor observer ratings are automatically perfect.

Why might a person know more about their own neuroticism than an observer?

Some anxiety and other emotional experiences are private and may not be visible to others.

Why might other people have useful information about someone’s personality?

They can observe how the person behaves and affects others in social situations.

What did Borkenau and Liebler (1992) ask strangers to judge?

The personality of people filmed reading a short weather report.

What information conditions were compared in the weather-report study?

Video with sound, video without sound, sound only, and a still image.

Which trait showed relatively strong self–other agreement in the weather-report study?

Extraversion.

What was the self–other agreement for extraversion using the full weather-report clip?

r = .51.

What did Naumann et al. (2009) compare?

Personality judgments based on structured versus spontaneous photographs.

What is a structured photograph in the Naumann study?

A photograph taken with instructions to face the camera and show a neutral expression.

What is a spontaneous photograph in the Naumann study?

A photograph in which the person could present themselves more freely.

Why might spontaneous photographs provide more trait-relevant information?

They can show variation in expression, posture, clothing, and personal presentation.

What two factors influence trait visibility?

The specific trait being judged and whether the situation provides relevant information.

Why might extraversion be relatively visible?

It is associated with observable behaviour such as sociability and talkativeness.

Why might neuroticism be less visible in a neutral situation?

Emotional reactivity may be private or may be more likely to appear in a stressful context.

What does it mean for a situation to afford a trait expression?

The situation provides an opportunity for trait-related behaviour or experience to appear.

What is Brunswik’s lens model?

A model explaining how observers use available cues to judge a characteristic they cannot directly observe.

Who is the target in personality-judgment research?

The person whose personality is being assessed.

Who is the judge in personality-judgment research?

The observer making a judgment about the target.

What is a cue in the lens model?

An observable piece of information, such as voice, facial expression, posture, or clothing.

What is cue validity in the lecture’s studies?

The relationship between an observable cue and the target’s self-rated personality trait.

What is cue utilisation?

The relationship between an observable cue and the observer’s judgment of the target’s personality.

What is the difference between cue validity and cue utilisation?

Validity concerns the cue and the target’s self-rating; utilisation concerns the cue and the observer’s rating.

What was the cue validity of friendly expression for extraversion in the lecture example?

r = .39 with the target’s self-rated extraversion.

What was the cue utilisation of friendly expression for extraversion in the lecture example?

r = .62 with the observer’s extraversion judgment.

What is convergence in the lens model?

The extent to which the pattern of cue utilisation matches the pattern of cue validity across cues.
