Karen Horney began as a psychoanalytic theorist. However, she soon found classical Freudian ideas too restrictive in their emphasis on sexual and aggressive motives. 5 ways she widened and modified classical psychoanalysis are
1. Childhood as a period of anxious helplessness and hidden anger toward all powerful but indifferent adults. 2. Neurotic strategies to cope with the anxiety and anger that alienate the person from the true self; the neurotic person is not comfortable in his or her own skin but must avoid, attack, or completely comply with others. 3. Male envy of the ability of women to give birth (womb envy) and to breast-feed. 4. A desexualized Oedipus complex, in which the key issues are power and love rather than sexuality and guilt. 5. The importance of culture, not biology, in determining personality makeup and areas of conflict.
Neurotic needs differ from those experienced by psychologically more normal people. Such needs
1. evidence disproportionate intensity 2. are indiscriminately applied to others 3. evidence an extreme disregard for reality 4. show a tendency to provoke intense anxiety when unsatisfied.

Raul's actions are an example of which of the following techniques?
Shaping
Group Polarization
Shifts or exaggeration in group members' attitudes or behavior as a result of group discussion.
Compartmentalization
Similar to blind spots, it involves pigeonholing one's life into rigid and exclusive categories: Thus, there is a compartment for friends, for enemies, for family, for outsiders, a compartment for professional activities separate from personal life, and so on). The important point is that anything that occurs in one compartment cannot contradict, influence, or support what transpires in another. It is, thus, as much a result of being divided by one's conflicts as a defense against recognizing them. A widely cited example is that of the man who ruthlessly runs his business affairs during the week, taking no real interest in the hurt or humiliation he causes his competitors, and on Sunday serves as the deacon of his church. Religion and business are in separate compartments, and so too, unfortunately, is his humanity. Horney herself may be viewed as someone who did it as well. Her professional life involved helping people overcome the very conflicts that she continued to express in her personal life.

Arbitrary Rightness
Some neurotics make important decisions arbitrarily—even those that have an impact on others—and then defend them with anything but thorough explanations. When questioned why a decision has been made, a typical answer would be, "Because I said so!' Horney felt that the most fertile type of personality for such arbitrary rightness was one with aggressive tendencies coupled with feelings of detachment from others. For example, a neurotic may end a family dispute by preemptively declaring that he will do what he has already decided to do since he is right. He then storms off, effectively ending the argument by absenting himself to pursue a course of action chosen more in spite than by reason.
Elusiveness
Sometimes the only way neurotics can avoid the inherent contradictions of their lives is through elusiveness—to avoid making any decisions whatsoever. Completely opposite to the arbitrarily right neurotic, the elusive neurotic seeks never to be pinned down to anything, never to state any issue or opinion clearly. "They have a bewildering capacity to becloud issues. It is often impossible for them to give a concrete report of any incident; should they try to do so the listener is uncertain in the end just what really did happen" (Horney, 1945, p. 138).

Cynicism
To defend against the recognition of inner conflict, the neurotic may adopt cynicism, a cynical stance toward life and its traditional moral and ethical values. By treating such issues derisively (in a manner expressing contempt or ridicule.), the neurotic can forestall any conflict over deciding what his or her own position is. In effect, he or she adopts the attitude "Do what you please, so long as you don't get caught" (Horney, 1945, p. 140). Horney's feminist, culturally based modifications of Freudian theory: Oedipus complex as culturally rather than biologically determined. She saw it as resulting from jealousy and aggression within some families. For Horney, the roots of the Oedipal situation consisted largely of interpersonal Attitudes. She desexualized the Oedipal conflict and transferred the dynamics of its emotional constellation into the realm of disturbed interpersonal relations. The resulting picture may look exactly like what Freud describes as the Oedipus complex; passionate clinging to one parent and jealousy toward the other or toward anyone interfering with the claim of exclusive possession.... The dynamic structure of these attachments is entirely different from what Freud conceives as the Oedipus complex. They are an early manifestation of neurotic conflicts rather than a primarily sexual phenomenon.

we determine our emotion based on our physiological arousal, then label that emotion according to our explanation for that arousal
resting potential
when a neuron is in polarization; more negative ions are inside the neuron cell membrane with a positive ions on the outside, causing a small electrical charge; release of this charge generates a neuron's impulse (signal/message)
Early Adulthood
- 20 - early 40s - physical maturation is complete - height and weight may increase slightly - physical abilities are at their peak (muscle strength, reaction time, sensory abilities, and cardiac functioning) - many women have children during this time (additional weight gain and breast changes)
Cognitive development in adulthood
- Cognitive abilities remain steady throughout early and middle adulthood - Crystallized intelligence (information, skills, and strategies) hold steady as we age and could improve - In late adulthood, we begin to experience a decline in our fluid intelligence (information processing abilities, reasoning, memory) - Mental and physical activity delay cognitive decline and reduce mild cognitive impairment and dementia
Psychosocial Development during adulthood
- Healthy aging - we need to have and continue to find meaning throughout our lives - Early and middle adulthood is found through work and family life (Erikson - Generativity and intimacy) - Adults define themselves by their careers - Positive relationships with significant others in adult years contribute to a state of well-being - Affected by having a stable marriage - Adult children have a positive effect on parental well-being -Socioemotional Selectivity Theory
What is the most important reason for the delay in entering adult roles?
- changing cultural expectations - Young people are delaying marriage and work as they change majors and jobs multiple times
How were children viewed in the pre-industrial society?
- children were considered adults when they reached physical maturity - we have an extended time between childhood and adulthood called adolescence
Psychosocial development during adolescence?
- continue to improve and alter their sense of self as they relate to others (Identity vs. Role Confusion by Erikson) - some teens adopt the values their parents expect for them - some develop identities that are in opposition to their parents but align with a peer group
What happens to early maturing girls?
- may be teased or overtly admired - cause them to feel self-conscious about their developing bodies - higher risk for depression, substance abuse, and eating disorders
What happens to late blooming boys and girls?
- may feel self-conscious about their lack of physical development - Negative feelings are particularly a problem for late maturing boys → higher risk for depression and conflict with parents and more likely to be bullied
How does the way teens think change?
- move beyond concrete thinking and become capable of abstract thought. - Known by Piaget as Operational Thought
Who created the first modern hospice in England (1967)?
Cicely Saunders
Who created the 5 stages of Grief?
Elisabeth Kubler-Ross
Who founded the first modern hospice in US (1974)?
Florence Wald
sensorimotor stage
Piaget's first stage; the stage (from birth to about 2 years of age) during which infants know the world mostly in terms of their sensory impressions and motor activities. Infants lack object permanence until about 8 months. They also develop stranger anxiety in this stage.
formal operational stage
Piaget's fourth stage; the stage of cognitive development (normally beginning about age 12) during which people begin to think logically about abstract events. They become capable of solving hypothetical propositions and deducing consequences.
habituation
decreasing responsiveness with repeated stimulation. As infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner
emerging adulthood
for some people in modern cultures, a period from the late teens to mid-twenties, bridging the gap between adolescent dependence and full independence and responsible adulthood
secondary sex characteristics
non-reproductive sexual characteristics, such as female breasts and hips, male voice quality, and body hair
self-concept
our understanding and evaluation of who we are
What is the primary influence on our development in adolescence?
peers
theory of mind
people's ideas about their own and others' mental states--about their feelings, perceptions, and thoughts, and the behaviors these might predict
fetal alcohol syndrome (FAS)
physical and cognitive abnormalities in children caused by a pregnant woman's heavy drinking. In severe cases, symptoms include noticeable facial misproportions
aggression
physical or verbal behavior intended to hurt someone
Secondary sexual characteristics
physical signs of sexual maturation that do not directly involve sex organs (development of breasts and hips in girls/development of facial hair)
stranger anxiety
the fear of strangers that infants commonly display, beginning at about 8 months of age
zygote
the fertilized egg; it enters a 2-week period of rapid cell division and develops into an embryo
spermarche
the first ejaculation
Why is hospice beneficial?
- provides care for 1.65 million Americans and their families - Beneficial for the patient and their family - Hospice patients tend to live longer than non-hospice patients - Able to die in the comfort of their own home
Adolescent brain
- remains underdeveloped - Up until puberty, brain cells continue to bloom in the frontal region - Adolescents engage in increased risk-taking behaviors and emotional outbursts possibly because the frontal lobes of their brains are still developing
What happens to early maturing boys
- tend to be stronger, taller, and more athletic than their later maturing peers - more popular, confident, and independent - greater risk for substance abuse and early sexual activity
Teen thinking is characterized by...
- the ability to consider multiple points of view - imagine hypothetical situations - debate ideas and opinions - Form new ideas - Not uncommon to question authority or challenge societal norms
Cognitive empathy/Theory-of-mind
- the ability to take the perspective of other and feel concern for others - Begins to increase in adolescence - An important component of social problem solving and conflict avoidance - Girls develop cognitive around 13, and boys 15 - Teens with supportive fathers who are easy to talk to about their worries were found to have better cognitive empathy
Menarche
- the beginning of menstrual periods (12-13 years old)
spermarche
- the first ejaculation (13-14 years old)
Adrenarche and Gonadarche
- the maturing of the adrenal glands and sex glands - occurs during puberty
Adolescence
- the period of development that begins at puberty and ends at emerging adulthood (12-18 years) - in USA, seen as a time to develop independence from parents while remaining connected to them - peers are a primary influence on our development in adolescence
Adulthood
- when she/he becomes self supporting, chooses a career, gets married, or starts a family - varies by person and culture - adult life has been delayed in western cultures
Toddlerhood (Erikson's stage of development)
1 to 3 years; autonomy vs. shame and doubt; exercise will and do things for themselves or doubt abilities
5 stages of grief
1) Denial 2) Anger 3) Bargaining 4) Depression 5) Acceptance - Stages can occur in different order - Not all people experience all the stages - The more a dying person fights death, the more likely they are to remain in the denial phase
Middle adulthood (Erikson's stage of development)
40s to 60s; generativity vs. stagnation; sense of contributing to world or feel a lack of purpose
Elementary school (Erikson's stage of development)
6 years to puberty; industry vs. inferiority; apply themselves to tasks or feel inferior
concrete operational stage
Piaget's third stage; the stage of cognitive development (from about 6 or 7 to 11 years of age) during which children gain the mental operations that enable them to think logically about concrete events. Children in this stage begin to grasp conservation, and they are able to understand mathematical transformations.
Adolescence (Erikson's stage of development)
teen years into 20s; identity vs. role confusion; refine sense of self or become confused
role
a set of expectations (norms) about a social position, defining how those in the position ought to behave
gender role
a set of expected behaviors for males or for females
cross-sectional study
a study in which people of different ages are compared with one another

teratogens
agents, such as chemicals and viruses, that can reach the embryo or fetus during prenatal development and cause harm
cognition
all the mental activities associated with thinking, knowing, remembering, and communicating
attachment

maturation
biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
The way we view death is influenced by what?
culture and individual backgrounds
social identity
the "we" aspect of out self-concept; the part of our answer to "Who am I?" that comes from our group memberships
gender typing
the acquisition of a traditional masculine or feminine role
object permanence
the awareness that things continue to exist even when not perceived

social clock
the culturally preferred timing of social events such as marriage, parenthood, and retirement
embryo
the developing human organism from about 2-weeks after fertilization through the second month
menarche
the first menstrual period
testosterone
the most important of the male sex hormones. Both males and females have it, but the additional testosterone in males stimulates the growth of the male sex organs in the fetus and the development of the male sex characteristics during puberty.
puberty
the period of sexual maturation, during which a person becomes capable of reproducing
egocentrism
the preoperational child's difficulty taking another's point of view
conservation
the principle (which Piaget believed to be a part of concrete operational reasoning) that properties such as mass, volume, and number remain the same despite changes in the forms of objects

X chromosome
the sex chromosome found in both men and women. Females have two X chromosomes; males have one. An X chromosome from each parent produces a female child.
Y chromosome
the sex chromosome found only in males. When paired with an X chromosome from the mother, it produces a male child.
