Lifespan Psychologists
developmental psychologists who focus on development throughout one's entire life
Child Psychologists
Developmental psychologists who focus on development only throughout childhood
Erik Erikson
First psychologist to champion that development lasts an entire lifetime
Normative development
typical sequence of developmental changes for a group of people
Cross-sectional studies
compares groups of people of various ages (for developmental psychology's purpose) on similar tasks
longitudinal method
following a small group of people over a long portion of their lives in order to observe change
maturationists
psychologists who emphasize the role of genetically programmed growth and development on the body, particularly the nervous system
maturation
biological readiness
environmentalists
psychologists who emphasize the role of learning and that everything can be learned (blank slate: tabula rasa)
continuous development
gradual development
discontinuous development
stage-oriented development
critical period
time during which a skill or ability must develop
stages
patterns of behavior that occur in a fixed sequence
zygote
fertilized egg that goes through 3 stages of gestation before birth
germinal stage
when the zygote divides into 64 cells and implants itself in the uterine wall; lasts around 2 weeks
embryonic stage
when the organs form; lasts until the beginning of the third month of pregnancy
fetal stage
when sexual differentiation and movement occur; very rapid growth is present during this
teratogens
harmful environmental agents that can have aversive effects on fetal development
fetal alcohol syndrome
when a mother consumes alcohol, leading a child to have physical abnormalities and cognitive deficiencies
Rudimentary Movement
first voluntary movements performed by a child
fundamental movement
occurs from ages 2-7; consists of running, throwing, jumping, and catching; highly influenced by the environment
specialized movement
when children learn to combine fundamental movements and apply them to tasks; broken down into transitional and application substages
transitional substage
when specialized movement combines to do things like sports
application substage
when a child chooses to apply specialized movements to tasks like sports
environmental interaction
the environment we grow up in and what has a large effect on the nervous system
Jean Piaget
Proposed an influential theory on children's cognitive development called equilibration
Equilibration
a child's attempt to reach a balance between what they encounter in the environment and their own cognitive structures
assimilation
incorporating new ideas into existing schemas
schema
mental representation model
accommodation
altering existing schemas to include new information
sensorimotor stage
ages 0-2; children act on objects that are present and begin to develop schemas yet are incapable of using them
object permanence
the knowledge that objects continue to exist, even if they are out of view
preoperational stage
ages 2-7; able to use schemas but cannot perform mental operations
symbolic thinking
the ability to use words to substitute for objects when thinking
egocentrism
seeing the world from only one's point of view
artificialism
believing everything is man made
concrete operational stage
ages 7-11; children can use schemas and perform mental operations yet cannot think theoretically
reversibility
to be able to start somewhere and think something, only to return back to the starting point (go back on your thoughts)
formal operational stage
ages 12 on; children are fully capable of understanding abstractions and symbolic relationships
metacognition
the ability to recognize one's cognitive processes and adapt them if they aren't successful
Lev Vygotsky
Stressed social factors as extremely important for development; theorized the zone of proximal development, actual development level, potential development level, and internalization
internalization
the absorption of knowledge into the self from environmental and social contexts
Zone of Proxiamal Development
range between the developed level of ability and the potential level for ability (needing an adult's help for some but not all)
wisdom
a form of insight into life situations and conditions that results in good judgement
fluid intelligence
the ability to think in terms of abstract concepts and symbolic relationships; decreases after age 60
crystallized intelligence
specific knowledge of facts and information; continues to increase after age 60
psychosexual development
development of an awareness of one's own sexuality
Sigmund Freud
created psychosexual stages to explain his patient's fixations
oral stage
ages 0-2; when the primary source of pleasure for an infant is sucking
anal stage
ages 2-3; when toddlers are praised for doing well in potty training
phallic stage
ages 3-6; when children connect their sex to gender and begin to wonder what it means
latency stage
ages 6-12; no particular body part, when children begin to closely associate with people of their own gender
genital stage
ages 12 and on; when the genitals are the main source of pleasure for the child as they are going through puberty
gender typing
the acquisition of gender specific roles
gender constancy
the idea that gender is a fixed, unchangeable characteristic
androgyny
when people blur the line between their and gender and stereotypical gender roles
Albert bandura
believed sexual roles could be acquired through social learning
Alfred Kinsey
Studied people's attitudes towards sexuality and created a scale to describe it
Kinsey Scale
sexuality is not binary, either exclusively heterosexual or homosexual; it exists along a continuum of attractions and practices
psychosocial development
8 stages described by Erik Erikson meant to describe social development across a lifetme
trust vs mistrust
ages 0-1; when infants must decide whether the world is friendly or hostile
autonomy vs shame
ages 1-3; when a child must develop control over their body and the environment around them
initiative vs guilt
ages 3-6; when children must assert themselves socially in order to feel a sense of purpose
industry vs inferiority

identity vs role confusion
ages 12-early adulthood; when adolescents must figure out who they are and how they fit in
fidelity

integrity vs despair
old age to end of life; an elderly person's struggle to come to terms with the end of their own life
Konrad lorenz
researcher who believed that childhood attachment is innate
Harry and Margaret Harlow
conducted a study with monkeys that proves infants need comfort and security just as much as food
John Bowlby
father of attachment theory; believed a strong relationship with parents helps create good relationship building skills later in life
Mary Ainsworth
Studied human infant attachment through an experiment coined the strange situation
Strange situation
experiment conducted by Mary Ainsworth that identified four attachment patterns: secure, avoidant, ambivalent, and organized
Secure
happy when around the caretaker but sad when they leave
avoidant
inhibited when around the caretaker and no emotion when they leave(they are actually stressed but pretending not to be)
ambivalent
mixed emotions around the caretaker but upset when they leave
disorganized
erratic relationship with the caretaker, more common in cases of serious neglect or abuse
Diana Baumrind
Identified 3 parenting styles: authoritarian, authoritative, and permissive
authoritarian
very high level of control and little warmth; harsh punishments

permissive
little demands and expectations; very low control but high warmth
Elisabeth Kubler-Ross
Developed a five stage model for accepting your own death(also used for grief): denial, anger, bargaining, depression, and acceptance
moral development
3 level theory (consists of 6 stages) created by Lawrence Kohlberg
preconventional morality
made up of two stages: judgements by fear and judgements by personal gain
conventional morality
occurs from ages 10 and beyond; involves living up to expectations and developing a conscience
postconventional morality
marked by stage five, individual rights trump the social contract; and stage 6, the social contract trumps everything
Carol Gilligan
Believed women could not reach stage 6 of Kohlberg's theory as human lives were more important to them than the social contract
Lawrence Kohlberg
Created the 6 stage or 3 level theory of morality and how it develops throughout our lifetimes
