Set 3: Developmental Psychology Flashcards
A job in psychology that studies that physical, cognitive, and social-emotional development throughout a human or animals lifespan.
Developmental physcologist
Darwin believed in survival of the fittest. Those traits that were best able to aid in survival were kept, those that weren’t were lost.
Natural Selection
The unethical process for selectively breeding for desired traits.
Eugenics
is a complete set of instructions for making an organism.
Genome
Genes
are biochemical units of heredity
Mutations
Occur when there is a random error in gene replication that leads to change.
Conception
A single ______ cell penetrates the outer coating of an _____ and fuses to form __________ _________ __________.
Sperm
Egg
One fertilized cell
This is a fertilized cell with 100 cells that become increasingly diverse.
Zygote
At about 14 days the zygote turns into
Embryo
At 9 months the embryo turns into a
Fetus
are chemicals or viruses that can enter the placenta and harm the developing fetus
Teratogens
which are physical and cognitive defects because of a mother’s heavy drinking while pregnant.
An example of the harm of teratogens can be seen with Fetal Alcohol Syndrome
Study different people across differing age groups to note changes in development. (Study at the same time).
Cross Sectional Study
Study the same group of people as they develop and note changes
Longitudinal Study
Infants are born with reflexes that aid in survival.
Reflexes
Baby turns head toward source of touch.
Nourishment
Rooting Reflex
Baby grasps on to object
Grasping Reflex
Arms and legs spring out, fists clench
Startle Reflex
Infants tend to pay attention to newer things for longer periods of time than older things
Habituation
Newborn to toddler
Infancy
Toddler to teenager
Childhood
The developing brain over produces neurons. Peaking around 28 billion at 7 months, these neurons are pruned to 23 billion at birth. The greatest neuronal spurt is in the frontal lobe enabling the individual to think rationally.
Developing Brain
The development of the brain unfolds based on genetic instructions, causing various bodily and mental functions to occur in sequence - standing before walking, babbling before talking
__________ sets the basic course of development, while experience adjusts it.
Maturation
Examples: Sitting up, walking, potty training, etc.
Motor development
Skills that require small muscle groups. Like pinching, picking up items, etc.
Fine Motor Skills:
Skills that require large muscle groups. Like walking, crawling, etc.
Gross Motor Skills:
The earliest age of conscious memory is around 3 ½ years (Bauer, 2002). A 5-year-old has a sense of self and an increase long-term memory, thus organization of memory is different from 3-4 years.
Maturation and Infant Memory
Jean Piaget believed that the driving force behind intellectual development is our biological development amidst experiences with the environment. Our cognitive (thinking) development is shaped by the errors we make.
Cognitive Development:
What did Jean Piaget believe.
are mental molds into which we pour our experiences. (folders)
Schemas
involves incorporating new experiences into our current understanding (schema).
assimilation*
The process of adjusting a schema and modifying it is called
accommodation
Piaget’s 4 Stages of Cognitive Development:
Sensorimotor
Birth-2 years (Level 1)
Explore the world through senses
Developmental Phenomena (Important milestones):
*Object Permanence – (knowing an object exists even if you can’t see it)
*Stranger Anxiety
Piaget’s 4 Stages of Cognitive Development:
Preoperational
2-6 or 7 years old (Level 2)
Thinking with their “gut”
Developmental Phenomena (Important milestones):
*Pretend play
*Egocentrism – (inability to see from a new perspective)
*Language Development
Animism - Giving lifelike traits to
inanimate objects.
Parallel Play - Kids play alongside
each other but play independently.
Piaget’s 4 Stages of Cognitive Development:
Concrete Operational
7-11 years old (Level 3)
Thinking logically
Developmental Phenomena (Important milestones):
*Conservation – Physical properties stay the same even if appearance changes
*Mathematical Transformations
Piaget’s 4 Stages of Cognitive Development:
Formal Operational
12- adulthood (Level 4)
Thinking abstractly
Developmental Phenomena (Important milestones):
*Abstract Thinking
*Mature Moral Reasoning
Criticism of Piaget’s Stages
Much research has proven that children reach developmental stages earlier than Piaget thought. One specific example is the discovery that young children have a theory of mind, which is the opposite of egocentrism.
However, today’s researchers believe the following: (3)
- Development is a continuous process, not stages.
- Children express their mental abilities and operations at earlier ages than Piaget thought. (Flynn Effect)
- Thinking is much more complicated than Piaget thought (not just formal logic problems).
Lev Vgotsky’s Zone of Proximal Development
The key is the gap between what a kid can do and what they can’t do. That gap covers everything they could do with help. That is the key to development. He worked with scaffolding which means to subtly make things harder and harder to improve learning.
Origins of Attachment (4): (example)
-Harlow worked with baby rhesus monkeys.
-Gave them wire mother with food
-Gave them cloth mother without food
-Baby monkey chose to spend time with cloth mother, proving contact comfort is a strong factor in attachment
Origins of Attachment (5): (definition)
-Contact comfort
-Nourishment
-Familiarity
-Imprinting - Some animals attach to the first thing they see
-Provide a secure base

Parents with child, leave, then come back…
