Development across the Life Span Flashcards
The influence of our inherited characteristics on our personality, physical growth, intellectual growth, and social interaction.
Nature
The influence of the environment on personality, physical growth, intellectual growth, and social interactions. It also includes parenting styles, physical surroundings, economic factors, and anything that can have an influence on development that does not come from within the person.
Nurture
A gene that actively controls the expression of a trait. Always expressed in the observable trait.
Dominant Gene
A gene that only influences the expression of a trait when paired with an identical gene. Also recedes or fades into the background when paired.
Recessive Gene
Rod-Shaped structures found in the nucleus of each cell and are nothing more than tightly wound strands of genetic material or DNA. 23 in each the egg and the sperm,when united to form the zygote there are 46 total.
Chromosome/s
The female sex cell, or egg.
Ovum
The union of the ovum and sperm.
Fertilization
Cell resulting from the uniting of the ovum and sperm; divides into many cells, eventually forming the baby.
Zygote
Formed when one zygote splits into two separate masses of cells, each of which develops into a separate embryo with the same genetic composition.
Monozygotic Twins
(Identical Twins)
Occur when two eggs get fertilized by two different sperm, resulting in the development of two zygotes in the uterus at the same time making them just ordinary siblings.
Dizygotic Twins
(Fraternal Twins)
Babies are born with these which help in their survival, innate involuntary behavior.
(Five Infant Reflexes)
- Grasping
- Moro (startle)
- Rooting
- Stepping
- Sucking
Developed a four-stage theory of cognitive development based on observation of infants and children.
Sensorimotor
Preoperational
Concrete Operations
Formal Operations
Jean Piaget
Sensorimotor Stage
Infants from birth to 2 years of age use their abilities to interact with the world.
(Piaget’s First Stage of Cognitive Development)
Preoperational Stage
Children from ages 2-7 can relate words or pictures to objects and events, and pretend.
Includes :(Egocentrism, Centration, Conservation, Irreversibility)
(Piaget’s Second Stage of Cognitive Development)
Centration
When young children pay attention to only one feature of an object while ignoring the rest of the object.
(Part 2)
(Piaget’s Second Stage of Cognitive Development)
Conservation
The ability to know that a change in the appearance of something does not change it’s nature.
(Part 3)
(Piaget’s Second Stage of Cognitive Development)
Irreversibility
Young children are unable to reverse an action with their brains.
(Part 4)
(Piaget’s Second Stage of Cognitive Development)
Formal Operations Stage
People from 12 years of age to adulthoodat can analyze information about something that is assumed or based on theory, consider sound reasoning of something that is possible, use reasoning and observation of an idea, and use some type of system to examine and test the idea.
(Piaget’s Forth (last) Stage of Cognitive Development)
The 3 Temperaments
(Temperament/s)
Easy - regular, adaptable, and happy
Difficult - irregular, nonadaptable, and irritable
Slow to warm up - need to adjust gradually to change.
Behavioral characteristics that are fairly well established at birth.
Egocentrism
When someone has the inability to see the world form a different prespective.
(Part 1)
(Piaget’s Second Stage of Cognitive Development)
