Lifespan Developmental Psychology Flashcards
Typical patterns of change.
Normative development
Developmental Psychology is ….
The study of how children and adults change over time. Includes biological, social, emotion and cognitive processes.
Individual variations in patterns of change.
Idiographic development
Fertilization occurs in the ..
Fallopian tube
Fertilization
When a sperm United w an egg or ovum and travels to the uterus.
Zygote
The fertilized ovum
Three stages of gestation or prenatal development.
Germinal stage
Embryonic stage
Fetal stage
Germinal stage
Lasts 2 weeks
Zygote moves down Fallopian tube and grows into 64 cells through cell division and implants itself into the wall of the uterus
Embryonic stage
Lasts from two weeks to end of 2nd month.
Organ formation.
Fetal stage
3rd month to birth
Quantitative growth and movement - quickening
Neonate
Newborn
Hormone that determines sex of baby
Testosterone - presence of H-Y antigen causes testis to form while absence causes ovaries to form. Occurs at 6 weeks
Neonate behavior is reflexive. 5 best known reflexes are:
Sucking Head turning Moro Babinski Palmar
Sucking reflex
Elicited by placing object in baby’s mouth
Head turning reflex
Elicited by striking baby’s cheek
Moro reflex
Throwing out of arms and legs elicited by loud or frightening noises
Babinski reflex
Fanning of toes elicited by touching bottom of foot
Palmar reflex
Hand grasping elicited by placing object in hand.
Time period of adolescence
13-19 years
Begins with puberty
Hormones that cause the visible secondary sex characteristics and growth spurt during adolescence.
The adrenal and pituitary glands secrete:
Androgen for boys
Estrogen for girls
The central debate in psychology
Nature vs Nurture
Genetics or environment determine behavior and personality
Monozygotic twins
Identical - have same genetic makeup.
Used to examine influence of genetics. Those separated at birth and raised in different homes may be used to study environment influence
Dizygotic twins
Fraternal twins - share about half their genetic makeup just like all siblings.
Jean Piaget
Known for his work in child development - stages of cognitive development.
Piaget’s theory of cognitive development
Our experiences are what allow us to develop cognitively. Maturation allows us to expand our experiences. Our thinking about the world becomes more sophisticated as we assimilate and accommodate, thus adapting our schemas.
Assimilation
Fitting new information into existing ideas
Accommodation
Modifying schema to incorporate new information
Piaget’s 4 stages of cognitive development
Sensorimotor
Pre operational
Concrete operational
Formal operational
Sensorimotor
0-2
Reflexive behavior cued by sensation.
Circular reactions- repeat behavior to manipulate environment.
Object permanence- knowing object exists even in its absence.
Acquiring use of representations- visualizing or putting words to objects.
Pre operational
2-7
Egocentric understanding
Rapidly acquiring words and symbols.
Unable to perform mental operations - causality or quantity.
Concrete operational
7-12
Understand concrete relationships- simple math and quantity.
Conservation- change in shape doesn’t change volume.
Formal operations
12+
Understand abstract relationships- logic, ratios and values.
