Chapter 6 - Theories of Cognitive Development Flashcards
How did Piaget decide to investigate the origins of knowledge?
Not as philosophers had, through discussion and debate, but by doing experiments with children
What did Piaget believe about children?
- They’re naturally curious
- They constantly want to make sense of their experience and, in the process, construct their understanding of the world
- Children at all ages are like scientists in that they create theories about how the world works, but of course, children’s theories are often incomplete (nevertheless, their theories are valuable because they make the world seem more predictable)
Summarize Piaget’s cognitive-developmental theory
- Children hold different concepts of the world at different ages
- Children are active constructors of these concepts
- Discontinuous; nature and nurture; active
What are the mechanisms of cognitive change?
Equilibrium by assimilation and accomodation
What is equilibrium in terms of cognitive change?
Responding to changes in environment in order to maintain a state of cognitive balance
What is assimilation in terms of cognitive change?
Interpreting new information in terms of what you already know
When does assimilation occur?
When new experiences are readily incorporated into a child’s existing theories
What is accommodation in terms of cognitive change?
Changing what you do or think to adapt to something new in the environment
When does accommodation occur?
When a child’s theories are modified based on experience
What is the process of equilibration in terms of cognitive change?
Children reorganizing their theories to return to a state of equilibrium
According to Piaget, when do revolutionary changes occur over the lifespan?
At approximately 2, 7, and 11 years of age
What is Piaget’s first stage of cognitive development? At what age does it occur? What does it encompass?
- Sensorimotor
- Birth to 2
- Infancy
What is Piaget’s second stage of cognitive development? At what age does it occur? What does it encompass?
- Preoperational stage
- 2 to 6
- Preschool and early elementary development
What is Piaget’s third stage of cognitive development? At what age does it occur? What does it encompass?
- Concrete operational stage
- 7 to 11
- Middle and late elementary school
What is Piaget’s fourth stage of cognitive development? At what age does it occur? What does it encompass?
- Formal operational stage
- 11 and up
- Adolescence and adulthood
What are “schemes”?
The basic act of knowing, including physical and mental actions
- Initially schemes are separate, but through experience children coordinate them into more complex ones
- E.g., grasping, looking, shaking, etc.
During the sensorimotor stage, how does the infant progress?
From simple reflex actions to symbolic processing
What generally happens during the sensorimotor stage: 1-4 months, 4-8 months, 8 months; 12 months
- 1 to 4: Reflexes are modified by experience
- 4 to 8: Infant shows greater interest in the world, paying far more attention to objects
- 8: Onset of deliberate, intentional behaviour
- 12: Infants become active experiementers
What is object permanence?
The understanding that objects exist independently (i.e., objects continue to exist even when you can’t see them)
What are the ages and abilities for the sub-stages of object permanence?
- Before 6 months: “Out of sight, out of mind”
- 4 to 8 months: Can uncover partially-covered objects
- 8 to 12 months: “A not B Error”
- 18 months to 2 years: Can uncover displaced objects (demonstrates object permanence)
What happens between 18 and 24 months once children can use symbols?
Begin to anticipate the consequences of actions mentally instead of having to perform them
What are the abilities and limitations of the sensorimotor stage?
- Learn about the world through sense and motor activity and combine different reflexes and abilities to form coordinated movements
- Can’t form mental representations and object permanence develops gradually over the stages
What is the main accomplishment of the sensorimotor stage?
Mental representation
- By 18 months, most infants have begun to talk and gesture which is evidence of the emerging capacity to use symbols
What marks the preoperational stage?
The child’s use of symbols to represent objects and events
- Children gradually become proficient at using common symbols, such as words, gestures, graphs, maps, and models
What do preoperational children typically believe?
That others see the world - both literally and figuratively - exactly as they do
What does egocentrism refer to?
Young children’s difficulty in seeing the world from another’s viewpoint (no awareness that there are other perspectives)
What is animism?
Preoperational children who sometimes credit inanimate objects with life and lifelike properties
What is centration?
Focusing on one aspect of a situation to the neglect of other important features
What is conservation?
Understanding that a quantity or amount of something remains the same, even when there are external changes in its appearance
What is an example of a conservation of liquid quantity problem?
Children are shown identical glasses filled with the same amount of juice and one is then poured from one glass into a taller, thinner glass. The juice looks different but the amount is unchanged. Nevertheless, preoperational children claim that the tall, thin glass has more juice than the original glass.
What is an example of a conservation of number problem?
When 2 rows of 4 coins are lined up but unequally spaced apart, a preoperational child will say that the row with 4 coins more spread apart has more coins
What is horizontal décalage?
The gradual development of abilities throughout a stage of development
How was categorization used to look at the abilities of preoperational children?
Children required to group by size, colour, and image. Adding multiple classes becomes more difficult.
How does the three mountains test demonstrate egocentrism?
Walked around a display of three mountains to see if from different perspectives and when positioned to only be able to see one thing, they chose a picture of what they saw from their own perspective at that time
What are the abilities and limitations of preoperational children?
- Can think using symbols and mental images
- They are not good at using symbols and mental images - have basic mental representation
- Centration and egocentrism (pay attention to one attribute of a situation at a time and unsystematic and illogical in their thinking)
What is the main accomplishment at the end of the preoperational stage?
Decentration
During what years do concrete operational children enter a new stage of cognitive development?
During the elementary school years, they enter one that is distinctly more adultlike and much less childlike
In the concrete operational stage, what do children use to solve problems and to reason?
Mental operations
What are mental operations?
Strategies and tools that make thinking more systematic and more powerful
In terms of the concrete operations stage, what is reversibility?
The ability to mentally go through a series of steps and then return to the starting point
In terms of the concrete operations stage, what is concrete?
Done with objects that can, in principle, be physically acted upon or manipulated
What is seriation?
The ability to arrange items along a quantitative dimension
What is transitive inference?
The ability to do seriation mentally
What is an example to show the difference between seriation and transitive inference?
Seriation - Child sees three sticks of different lengths and would be able to arrange them by size
Transitive inference - Child hears about the three sticks and can arrange them in their head
