Module 45; Developmental Issues, Prenatal Development, and the Newborn
Developmental Psychology
A branch of psychology that studies physical, cognitive, and social change throughout the life span
Nature and Nurture
Nature (Genetic inheritance) vs Nurture (Experience)
Continuity and Stages
Stability and Change
Biological, Psychological, Social interactions/interrelationships
Temperament
Emotional reactivity and intensity
Prenatal Development
Zygotes
The fertilized egg; it enters a 2 week period of rapid cell division and develops into an embryo
Embryo
The developing human organism from about 2 weeks after fertilization through the second month
Placenta
Life link that transfers nutrients and oxygen from the mother to the embryo
Fetus
The developing human organism from 9 weeks after conception to birth
Teratogens
(“Monster Maker”) agents such as chemicals, viruses, that can reach the embryo or fetus during prenatal development and cause harm
Fetal Alcohol Syndrome (FAS)
Physical and cognitive abnormalities in children caused by a pregnant woman's heavy drinking
In severe cases, signs include a small, out of proportion head and abnormal facial features
Epigenetic Effect
Leaves chemical mark on DNA and abnormally switches genes on and off
Newborn “reflexes”
Rooting Reflex
When something touches their cheek, babies turn towards the touch and naturally open their mouth and bite on it or near it
They may suck it, reflexive tongue, swallowing or breathing
Habituation
Decreasing responsiveness with repeated stimulation. An infants gain familiarity with repeated exposure to a visual stimulus, their interest wanes and they look away sooner
Visual preference; part of habituation
Infants focus on face not on body
Module 46; Infancy and Childhood: Physical Development
Maturation
Biological growth processes that enable orderly changes in behavior, relatively uninfluenced by experience
Use it or lose it ; pruning process
Shuts down unused links and strengthens others
Back to sleep position

A concept or framework that organizes and interprets information
Assimilation
Interpreting our new experiences in terms of our schemas
Ex; toddler may call any 4 legged animal a dog
Accommodation
Adapting our current understandings (schemas) to incorporate new information
Ex; learns dog is too broad and refines the category
Piaget's 4 Stages
Sensorimotor, Preoperational, Concrete Operational, Formal Operation
1. Sensorimotor (birth-2)
Infants know the world mostly in terms of their sensory impressions and motor activities
Looking, hearing, touching, mouthing, grasping
Lack Object Permanence
The awareness that things continue to exist even when not perceived
2. Preoperational (2-6/7 years)
Too young to perform mental operations ; does not comprehend the mental operations of concrete logic
But, learns to use language
Symbolic Thinking
Represents things with words or objects
Egocentrism
Difficulty to take another POV;
Ex; Do you have a brother, yes Jim. Does Jim have a brother, no
Theory of Mind
Peoples ideas about their own and others mental states; about their feelings, perceptions, and thoughts, and the behaviors these may predict
Curse of Knowledge
Overestimate the extent to which others share our opinions and perspectives
ASD; Autism Spectrum Disorder
A disorder that appears in childhood and is marked by significant deficiencies in communication and social interaction, and by rigidly fixated interests and repetitive behavior
3. Concrete Operational(6/7 to 11 years of age)
Children gain the mental operations that enable them to think logically about concrete events
Conservation
The principle that properties like mass, volume and number remain the same despite changes in form of objects
Ex; water poured in cups of different shapes with same amount of water, kids perceive it as more/less water
4. Formal Operational Stage (At age 12)
People begin to think about abstract concepts
Potential for mature moral reasoning
Lev Vygotsky
Child's zone of proximal development
Between what a child can and cannot do
Children may develop slowly or quickly based on support and guidance
Scaffold
Temporary support or guidance given to a learner to help them acquire a new skill or complete a task, gradually withdrawing that support as they become more proficient
Module 48; Infancy and Childhood; Social Development
Stranger Anxiety
Fear of strangers that infants display, beginning by about 8 months of age
The brain, mind and social emotional behavior develop together
Attachment
An emotional tie with another person; shown in young children by seeking closeness to the caregiver and showing distress on separation
Harlow
Monkey and robotic mother, which would the monkey go towards
Wire with bottle; food
Actual monkey looking figure; warmth
Critical Period
An optimal period early in life of an organism when exposure to certain stimuli or experiences produces normal development
Imprinting
Process by which certain animals form strong attachments during an early life critical period
Ex; Konrad and Ducks; everywhere Konrad went, the ducks went
Sensitive Period
A specific developmental window where a person is most receptive to learning certain skills or acquiring knowledge
Mere exposure
people prefer things they are familiar with
Mary Ainsworth
Study the interactions between infants and their parents, and the difference between those interactions and the interactions between the same infants and strangers.
Strange situation experiment
Secure Attachment
Style of relating to others that's characterized by trust, emotional connection, and safety
mothers
Insecure Attachment
Marked by anxiety or avoidance of trusting relationships
Ex; strangers
Basic Trust
Erikson and his wife
A sense that the world is predictable and trustworthy; said to be formed during infancy by appropriate experiences with responsive caregivers
Self Concept
All our thoughts, and feelings about ourselves, in answer to the question, who am I?
Parenting Styles
Authoritarian; impose rules and expect obedience
Permissive; parents submit to their children's desires, may few demands, use little punishment
Authoritative; demanding and responsive . Exert rules and control, but still explain these rules
Module 49; Gender Development
Gender
Biological, and social traits/characteristics
Sex
Biological traits that define male/female
Aggression
Any physical or verbal behavior intended to hurt or destroy
Gender role
A set of expected behaviors for males or females
Role
A set of expectations (norms) about a social position, defining how those in the position ought to behave

Module 52; Adolescence: Social Development and Emerging Adulthood
Identity
Erikson
Adolescents task to solidify a sense of self by testing and integrating various roles
Social Identity
The “We” aspect of our self concept; the part of our answer to WHO AM I, that comes from our group memberships
Erikson's stages of psychosocial development
Stage | Issue | Task |
Infancy (1 year) | Trust vs Mistrust | If needs are dependably met, infants develop a sense of basic trust |
Toddlerhood (1-3 years) | Autonomy vs shame and doubt | Toddlers learn to exercise their will and do things for themselves, or they doubt their abilities |
Preschool (3-6 years) | Initiative vs Guilt | Preschoolers learn to initiate tasks and carry out plans, or they feel guilty about their efforts to be independent |
Elementary School (6 years to puberty) | Competence vs Inferiority | Children learn the pleasure of applying themselves to tasks, or they feel inferior |
Adolescence (teen years to 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 |
Young Adulthood (20s to early 40s) | Intimacy vs isolation | Young adults struggle to form close relationships and to gain the capacity for intimate love, or feel socially isolated |
Middle Adulthood (40s-60s) | Generativity vs stagnation | People discover a sense of contributing to the world, or may feel a lack of purpose |
Late Adulthood (60s and up) | Integrity vs despair | Reflecting on his or her life, an older adult may feel a sense of satisfaction or failure |
Intimacy
Ability to form close, loving, relationships, a primary developmental stage in late adolescence, early adulthood
Emerging Adulthood
For some in modern cultures, a period from the late teens to mid twenties, bridging the gap between adolescent dependence and full independence and responsible adulthood
Module 53; Sexual Development
X-Chromosome
The sex chromosome in men and women. Females have 2, males have 1. An X chromosome from each parent produces a female child
Y Chromosome
The sex chromosome found ONLY in men. When paired with an X chromosome from the mother, it produces a male child
Testosterone
Most important of male sex hormones. Males and females have it, but 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
Primary sex characteristics
Body structures (ovaries, testes, and external genitalia) that make sexual reproduction possible
Secondary sex characteristics
Nonreproductive sexual traits such as female breasts and hips, male voice quality and body hair
Menarche
The first menstrual period
AIDS (Acquired immune deficiency syndrome)
A life threatening sexually transmitted infection caused by HIV. AIDS depletes the immune system, leaving the person vulnerable to infections
Sexual Orientation
An enduring sexual attraction toward members of either one's own sex (homosexual) or the other sex (heterosexual) or both (bisexual)
Genetic Influences on these
Family studies, twin studies, fruit fly studies, prenatal influences
