Part One. Dispositional Domain

Still looking for universal personality traits!! How many personality traits exist? How do we classify these personality traits? How do we measure these traits?? Are the traits stable over time? Are the traits stable across situations? How do the traits develop?

What Is Personality Development?

Continuities, consistencies, stabilities in people over time

PLUS the way in which people change over time

Three Key Forms of Stability

(1) Rank order stability: Maintenance of an individual position’s within group

Temperament vs. Personality

Temperament: individual differences in emotional reactivity, attentional reactivity, and self-regulation

Temperament → Narrower Traits Personality → Broader Traits

2 Classic Theories of Temperament

Page 19: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

How could we measure temperament in children?

© 2015 M. Guthrie Yarwood 19

Page 20: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

Thomas & Chess(1977)

Easy Temperament (40%) Even tempered, positive, open and adaptable to new

experiences and situations

Difficult Temperament (10%) Active, irritable, and irregular in their habit. React very

negatively to new situations and people

Slow-to-Warm up Temperament (15%) Low activity level, sometimes moody, and slow to

warm up in new situations/experiences

Page 21: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

Temperament Description

Activity Is the child always moving and doing something OR does he or she have a more relaxed style?

Rhythmicity Is the child regular in his or her eating and sleeping habits OR somewhat haphazard?

Approach / withdrawal Does he or she "never meet a stranger" OR tend to shy away from new people or things?

Adaptability Can the child adjust to changes in routines or plans easily or does he or she resist transitions?

Intensity Does he or she react strongly to situations, either positive or negative, OR does he or she react calmly and quietly?

Page 22: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

© 2015 M. Guthrie Yarwood 22

Temperament Description

Mood

Does the child often express a negative outlook OR is he or she generally a positive person? Does his or her mood shift frequently OR is he or she usually even-tempered?

Persistence and Attention Span

Does the child give up as soon as a problem arises with a task OR does he or she keep on trying? Can he or she stick with an activity a long time OR does his or her mind tend to wander?

DistractibilityIs the child easily distracted from what he or she is doing OR can he or she shut out external distractions and stay with the current activity?

Sensory ThresholdIs he or she bothered by external stimuli such as loud noises, bright lights, or food textures OR does he or she tend to ignore them?

•Positive mood, high regularity, low intensity, adaptability, approach (not withdrawal)

Easy•Negati

ve mood, irregularity, extreme intensity, slow to adapt, withdrawal, loud crying/laughter

•Low activity, withdrawal, slower to adapt, somewhat negative mood, low intensity

configuration

Were not consistent in the types of behaviors they displayed across different situations or over time

In-Class Exercise:Name the dimension!1. During quiet time, how often did you child enjoy

just being quietly sung to?

2. When encountering a new activity, how often did you child get involved immediately?

3. While playing indoors, how often did you child like rough and rowdy games?

4. During everyday activities, how often did you child seem to be irritated by tags in his/her clothes?

Bringing It Together

Rank-order stability and mean-level stability for personality Although small changes exist for certain ages

Major life events cause mean-level change But, not rank-order change

Personality Coherence

How does society/culture change people’s personality? Narcissism and the Birth Cohort Effect

How do people express personality traits as they age? Delay of gratification and the marshmallow study

Page 55: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

Personality Coherence: Birth Cohort Effect

Changes in personality due to to living in different time periods

Ex: Is the increase in narcissism….. True change? A cohort effect?

Personality Changes Across Cohorts: Subclinical Narcissism

Little interest in forming warm, emotionally intimate bonds with others; aggressively lash out when rejected or insulted; overconfident

When faced with common resources, take more for themselves and leave less for others

Positively correlated with extraversion and agency (i.e. traits typical of male gender role)

Page 57: Personality Dispositions Over Time: Stability, Change, and Coherence © 2015 M. Guthrie Yarwood1.

Personality Changes Across Cohorts: Subclinical Narcissism

“I usually get the respect I desire.”

“I find it easy to manipulate people.”

“I like to be the center of attention.”

Personality Stability: Across Life Periods

By comparing personality across life periods, we can identify small changes in personality over time.

In general, many of the changes are due to the maturity principles.

But, people may experience this “maturity” through biological/physical changes (plaster) or through environmental changes (plasticity)
