Piaget + Biology of development Flashcards
Piaget's stages of development ages, basic biological concepts of dev.
how many chromosomes do most human cells have
46
How many chromosomes are located in reproductive organs ?
23 ; both egg and sperm contain 23 chromosomes each, each of the 23 is homologous to the other pair in shape and function
The division of cells that happens in reproductive organs is called
MEIOSIS
Cell division in other parts of the human body is called
MITOSIS
The perspective that connects influences of different spheres of a child’s life together and among themselves is called
The Ecological Perspective
What is the goal of developmental psychology
It attempts to undercover the processes that underlie behaviour, growth and learning
What are three methods to gather data on children?
Interview, ask questions ; naturalistic observation (uncontrolled observation); Structured observation (experiment specially designed)
Which psychologist proposed a revolution theory in 1936 on children’s cognitive development
Jean Piaget
Quick definition of Jean Piaget’s theory
His theory proposes four main steps of development marked by qualitative differences, children construct their understanding of the world as a result of biological maturation as well as environmental experiences
One of Piaget’s four steps of dev : from 7-11 is called
Concrete operational (goal: Operational thoughts, they start to reason logically about the world and develop conversation skills)
Sensori-motor stage in Piaget’s theory, age and description
0-2 years old: infants know the world through their senses and actions, ex they learn what dogs look like, how it makes them feel to pet them
Age and Description of the Pre operational stage in Piaget’s theory
2 to 7 : child starts to internally represent the world through language and mental imagery. Acquisition of symbolic representation. Limitations: still quite egocentric, centration, lack of conservation
The final stage of Piaget’s theory is called + age and goal
Formal operational stage, 12+ yo. Ability to imagine other realities, think of abstract concepts, systematic planning and organisation
What is centration ?
Tendency to focus on a single, perceptually striking feature of an object or event
What is conservation?
The idea that merely changing an object’s appearance won’t change its properties
