parents creating positive outcomes for their children
promote positive development and good outcomes.
role parental education plays in child outcomes
Highly educated parents are linked to better outcomes for their children, leading to traits like openness, extroversion, and emotional stability in adulthood.

A supportive childhood environment, characterized by cognitive stimulation and higher parental SES, is beneficial for children's self-esteem.
factors that contribute to positive childhood development
Engagement in cognitively stimulating activities and having a father present in the home contribute to better developmental outcomes.
person-environment transactions
refer to how individuals respond to, seek out, and create environments that align with their personality traits.
active aspect of person-environment transactions
involves people seeking out environments that are compatible with their personality and avoiding those that are not.
the reactive aspect of person-environment transactions
means that individuals respond differently to the same situation based on their personality traits.

cohort effects contribute to research findings
age differences observed in cross-sectional studies.
influences of personality according to cohort effects
Aspects of personality can be affected by the historical period in which one lives.

a limitation mentioned in longitudinal studies
The La Dolce Vita effect is a limitation noted in some longitudinal research.
the "La Dolce Vita" effect
experience a decline in personality stability or maturity during periods of indulgence, pleasure-seeking, or lifestyle changes, often associated with a carefree or hedonistic lifestyle
DeYoung et al. (2021) suggestion about the causes of personality
the proximal causes of personality are biological, located in the brain, which generates behavior and experience
environments influence personality according to DeYoung et al. (2021)
by influencing the brain, leading to lasting changes in behavior and experience.
applications in understanding the brain and personality
helps cure or alleviate mental illness and improve quality of life.
neurotransmitters
chemicals that allow neurons (cells in the nervous system) to communicate and affect one another.
hormones
chemicals that regulate several body functions, including mood and stress response.
role of dopamine in the brain
allows the brain to control body movements and respond to rewards, influencing tendencies to approach appealing objects and people.
behaviors and traits associated with dopamine
related to sociability, general activity level, novelty seeking, approach behavior, and learning.
dopamines connection to mental health
have a possible relation to bipolar disorder and impulsivity, with concepts of hyperdopaminergia and hypodopaminergia
the system dopamine activates
the behavioral activation system (BAS) and reinforces the motivation to seek rewards.
role serotonin plays in behavior
helps control behavioral impulses, fear, and anxiety, lowering anger, oversensitivity, and excessive worrying.
the way serotonin agonists affects fear and anxiety
by decreasing the amygdala's reaction to threatening stimuli.
selective serotonin reuptake inhibitors (SSRIs) used for
help reduce neuroticism, including symptoms of depression and anxiety, by lessening the severity of negative emotions.
SSRIs make you
negative emotions less severe.
serotonin in organizing behavior
helps people organize their behavior and get work done, contributing to conscientiousness.
serotonin its affect on relationships with others
helps people get along with others, supporting agreeableness.
ways serotonin can influence emotional responses
helps avoid mood swings and emotional overreactions to life events, which is linked to lower neuroticism.
the roles of epinephrine and norepinephrine in the body
released in response to stress to create the fight-or-flight response.
ways females respond differently to stress compared to males
the tend-and-befriend response, calming others down and promoting teamwork to deal with the threat.
the role oxytocin plays in stress responses
promotes nurturant and sociable behaviors, relaxation, and reduces fear, increasing attachment between mothers and children.
the difference in testosterone levels between males and females
present in both males and females, but males have about 10 times higher concentration than females.
ways testosterone is related to behaviors in males
higher testosterone levels are associated with aggression, behavioral control problems, criminal behaviors (e.g., assault, drug use), and traits like avoidance, dominance, and loneliness.
high testosterone always lead to aggression in men
false, men with high testosterone are not always aggressive.
ways testosterone is related to behaviors in females
higher testosterone levels are associated with higher sociability, impulsivity, lack of inhibition, and lack of conformity.
testosterone only a cause of behavior
No, testosterone it can also be an effect.
ways sexual activity affect testosterone
activity may increase testosterone levels, but it does not decrease testosterone.
example of testosterone's relationship with behavior
direction of causality between testosterone and behavior is unclear.
example, testosterone levels increased among fans of a winning soccer (football) team and decreased among fans of a losing team
cortisol released in response to
stress (both physical and psychological) to help prepare the body for action.
the effects of high cortisol levels
related to severe stress, anxiety, and depression.
the effects of low cortisol levels
post-traumatic stress disorder (PTSD) and sensation seeking, which involves impulsivity and not following societal rules
the two metatraits of the Big Five
Stability and Plasticity.
the Stability metatrait includes
emotional stability, conscientiousness, and agreeableness. It describes the ability to control impulses and regulate emotions
the Plasticity metatrait includes
extraversion and openness. It focuses on the exploration of opportunities and experiences.
neurotransmitter is linked to
Plasticity and plasticity is linked to dopamine.
the two facets that Openness can be divided into
Intellect and Openness.
the facet "Intellect" in Openness refers to
being interested in abstract thought and theoretical speculations.
the facet "Openness" refers to
responding to aesthetic stimuli, including art, music, natural beauty, and even private fantasies.
the key structure for planning and self-restraint in the brain
frontal cortex.
the role the insula plays in conscientiousness
involved in generating potentially distracting impulses.
When the prefrontal cortex successfully overcomes distractions, people may display
self-control and pursue planned goals.
the connection between extraversion and dopamine
Extraverts respond more strongly to dopamine, meaning they enjoy rewards more and are highly motivated to seek them out.
the dopaminergic system stimulates the release of
endorphins.
the release of endorphins leads to
produces pleasure and a strong dopamine-mediated motivation to repeat the behavior, which can result in addiction.
the two brain processes important for Agreeableness
Mentalizing and Empathy.
Mentalizing in the context of Agreeableness
the ability to understand what other people are thinking.
empathy in the context of Agreeableness
the ability to understand other people’s feelings.
brain structure most associated with neuroticism
The amygdala.
the amygdala plays in neuroticism
a key role in processing emotions, especially negative ones such as anger and fear.
the amygdala response in shy people
becomes highly active when they are shown pictures of people they don't know.
the anxiety disorders associated with an active amygdala
Panic attacks and post-traumatic stress disorder (PTSD).
happens when the amygdala is aroused by the perception of threat or danger
It causes cortisol to be released into the bloodstream.
the long-term effects of elevated cortisol levels due to amygdala arousal
Increased risk of diabetes and heart disease, declines in mental health, especially higher levels of anxiety and depression.
stressful events
raise cortisol levels, which can increase tendencies toward anxiety and depression.
ways research on the brain and chemicals affected personality
aided the development of therapeutic drugs, helping people deal with anxiety, depression, and more severe kinds of psychopathology
the relationship between the brain and environment work
in both directions: biological processes are as often the effects of behaviors or experiences as they are the causes.
example of how biological processes are influenced by the environment
A stressful environment can raise cortisol levels, and feeling depressed or anxious can also raise cortisol, which may result in a smaller brain.
evolutionary psychology suggest that the
patterns of behavior in our personalities may have originated in ways that promoted survival and reproduction.
ways behavioral genetics relates to personality
addresses how individual differences in personality are passed from parent to child and shared by biological relatives.
