ch. 9 Flashcards
Development
The pattern of continuity and change in human capabilities that occurs throughout life and it includes both growth and decline
Nature
Biological inheritance
Aspects of development
Physical, cognitive, and socioemotional
Nurture
Environmental experiences
Self’s influence on development
Individuals take active roles in own development
Germinal Period (1-2 weeks)
AKA Zygotic period
conception
fertilization
zygote
Embryonic period (Weeks 3-8)
Differentiation of tissue
organ formation
Fetal period (2-9 months)
Development of functionality
Prenatal Development: Teratogens
Agents that cause birth defects
-nicotine
-alcohol
-STIs
Why are the first 8 weeks a sensitive period of development?
All of the major organs and body systems are forming and can be damaged if the fetus is exposed to drugs, alcohol, and STIs, etc.
Reflexes
Genetically wired behaviors and some are crucial for survival
-coughing, blinking, and yawning
Grasping
an involuntary response.
Rooting
This reflex starts when the corner of the baby’s mouth is stroked or touched
Moro
a normal reflex for an infant when he or she is startled or feels like they are falling.
ex. they have a startled look and the arms will fling out sideways with the palms up and the thumbs flexed
Galant “fencing”
This reflex occurs when the side of the infant’s spine is stroked or tapped while the infant lies on the stomach.
ex. the infant will twitch their hips toward the touch in a dancing movement
Stepping

Toe Curling/Babinski

Jean Piaget (1896-1980)
Children actively construct their cognitive world using:
Schemas
-concepts or frameworks that organize information
Assimilation
-apply old (existing) schemas to new experiences
Accommodation
-Adjust/alter schemas to new information
sensorimotor stage (birth-2 years)
coordinate sensations with movements
preoperational stage (2-7 years)
symbolic thinking: words & images
intuitive reasoning
Egocentrism
Lacks operations (reversible mental processes
concrete operational stage (7-11 yrs)
operational thinking (e.g., conservation)
reversibility
classification skills
reason logically in concrete contexts
Formal operational stage (11-15 yrs)
lasts through adulthood
abstract and idealistic thought
hypothetical-deductive reasoning
Concrete thinking
Ability to produce operational thinking
-better able to have advanced hierarchy of characteristics
Attachment
close emotional bonds between an infant and their primary caregiver
-high quantities of oxytocin creates an easier time when bonding
-creates the groundwork for later in life relationships
-if not exercised in early life it can affect future relationships
