(1) Congruence (genuineness/realness) (2) Unconditional positive regard (acceptance/caring) (3) Empathy
Anal Stage
(1-3 yrs.) -Act of elimination -Child learns to control his bodily excretions -If someone makes you feel bad about an accident during this stage = unbending, controlling attitude later in life
Embryo
(2 to 9 weeks) ~10 days after conception, the zygote attaches to the mother's uterine wall. The zygote's inner cells form the embryo, the outer cells form the placenta. Over the next 6 weeks, the embryo's organs begin to form and function

Double Approach-Avoidance Conflict
(Stable; many different goals/more real-life) -A conflict in which one must choose between options that have many attractive and negative aspects -Ex: Choosing between a job that is far away but pays well, and a job that is nearby but with no room for advancement
Approach-avoidance conflict
(Stable; only one goal) -Conflict that results from an individual being both attracted and repelled by the same goal -Stress multiplies when facing many approach-avoidance conflicts -Ex: The timid man wishes to propose to his girlfriend fears rejection (avoid) and hopes for acceptance (approach)
Adolescence (Erikson)
(Teen years into 20s) Identity vs. Role Confusion -Teenagers work at refining a sense of self by testing roles and then integrating them to form a single identity, or they become confused about who they are
Infancy (Erikson)

-Based on the assumption that cognitive constructs (schemas) are the basis for personality -We bring them to every social situation (ex: expectations) -As we learn in social environments, we develop and modify our constructs
How did psychology continue to develop from the 1920s through today?
-Early researchers defined psychology as a "science of mental life" -In the 1920s, under John B. Watson and the behaviorists, the field's focus changed to "scientific study of behavior" -In the 1960s, the humanistic psychologists and the cognitive psychologists revived interest in the study of mental processes -Psychology is now defined as the "science of behavior and mental processes"
Carl Jung
-Evolutionist that proposed the *unconscious consists of two different parts* (personal unconscious and collective unconscious) that interact with the ego and the self and is a product of evolution -*Goal of personality development was to become individuated* (unification of conscious and unconscious processes) *to realize the self* -*Mind is made up of opposing forces* (ex: the persona who you present to the world vs. the shadow that is the deep, passionate, inner person) *all balanced out by the Self*
Alfred Adler
-Focused on the *conscious role of the ego* (inferiority complex: fear of failure & superiority complex: desire to achieve) *and people's social interest as the driving force behind their behavior* -Important work on how *birth order shapes personality* (ex: oldest is responsible/protective, middle is ambitious/well-adjusted, youngest is spoiled)

Limits on operant conditioning
-Nature limits species' capacity for operant conditioning -Biological constraints predispose organisms to learn associations that are naturally adaptive -Instinctive drift occurs as animals revert to biologically predisposed patterns
Humanist approach to personality
-Not deterministic (you have no control over your own personality, it's shaped because of events during your childhood) like psychoanalysis and behaviorist theories -People are innately good and determine their own destinies -Subjective experience and feelings are important (focus on self-concept and self-esteem) -People need to be motivated to reach their full potential (self-actualization)
Collective unconscious (Jung)
-Not unique to the individual, but rather a shared, inherited reservoir of memory traces by the entire human race -Archetypes (overarching human tendencies) are important for every person to become aware of so that they can become whole and individuated -These archetypes can be understood through studying philosophy, art, religion, mythology, and dreams
Heritability of personality traits
-People are born with a potential for intelligence that combines with environmental influences to determine adult intelligence levels -Psychological disorders are affected by the genes inherited, meaning some people are born with a higher susceptibility to disorders compared with others
Behavioral approach to personality
-Personality is determined by *environment/reinforcement* -"Personality" is meaningless, really just a collection of behaviors -*No cognitive element*, so often psychologists take a cognitive-behavioral approach
Hans Eysenck
-Personality is determined largely by genes -Used factor analysis to simplify personality into 3 dimensions (extroversion, neuroticism, and psychoticism) -Stepping stone to "Big 5"

Self-concept vs. self-esteem
-Self concept is how we view ourselves -Self esteem refers to how you feel about yourself

How can alcohol affect babies during prenatal development?
As alcohol enters the mother's bloodstream, and her fetus', it depresses activity in both their central nervous system. Alcohol use during pregnancy may prime the offspring to like alcohol and put them at risk for heavy drinking + alcohol use disorder during teens. Persistent heavy drinking puts the fetus at risk for birth defects and for future behavior problems, hyperactivity, and low intelligence.
What is true of social relations during the teen years?
As teens distance themselves from parents, peer relationships become more important
Cerebral cortex and emotion
As the body's SNS kicks into gear, the brain's cerebral cortex, through the hypothalamus and pituitary gland, directs the adrenal glands to release stress hormones like cortisol. These hormones are responsible for a person's sustained response to stress.
How does memory change with age?
As the years pass, recall declines, especially of meaningless information, but recognition remains strong. Older adults rely more on time management and memory cues to remember time-based and habitual tasks. Dementia and Alzheimer's disease are brain ailments, not normal parts of aging. Developmental researchers study age-related changes (such as memory) with cross-sectional studies (comparing people of different ages) and longitudinal studies (retesting the same people over a period of years). "Terminal decline" describes the cognitive decline in the final few years of life.
