Cognitive Development in Early Childhood I. (Chapter 7) Flashcards
Myelination
-Nerve cells are covered and insulated with a layer of fat cells which increases the speed at which information moves through the nervous system
Preoperational Stage
-2nd major stage in Piaget’s theory
-children begin developing symbolic thinking and language skills
-use symbols like words and images to represent objects and ideas
Conservation
-the idea that the amount of something remains the same despite changes in its form, shape, or appearance
Stages of Conservation Development
- Stage 1 (3-4 years olds): non conservers
- Stage 2 (5-6 years old): transitional period
- Stage 3 (7 and above): mature conservation
Limitations of Non-conserver’s Thinking
- Centration
-Appearance-Reality Problem
-Focus on States
-Irreversibility
Centration
-Focus on one aspect of a situation (height, length)
Appearance-Reality Problem
-Confuse what is real with outward appearance (someone wearing a costume is actually the character they’re dressed as)
Focus on States
- Failure to understand the transformation between states
Irreversibility
-Failure to understand that some operations can be reversed (if you pour the water back from a short wide glass into a tall, narrow glass, the amount of water remains the same)
Strategies of Mature Conservers
-Compensation: thinking about multiple aspects of situations simultaneously
-Identify: recognizing two things are actually the same material, even if they look different on the outside (ice and water)
-Nothing added or subtracted criterion: some changes can be undone to get back to the original state
-Reversibility
Conservation Development (Piaget)
-Factors: physical growth, including brain development and personal experience
Training Studies (Neo-Piagetian approach)
-Key Question: can conservationists be taught?
-Findings: 4 year olds cannot learn conservation; 6 year olds in transitional phase benefit from training
-Conclusion:Piaget’s belief in biological constraints is accurate; non-conservers and conservers think differently
Preoperational Thinking: Other Aspects
-Classification: age 3 uses (group things solely by color or shape) one criterion; age 4 uses two criteria (consider multiple attributes)
-Causation: transduction
-Living and Non-living things: animism- common aspect of imaginative and symbolic thinking in early childhood
Transduction
- Children mentally link two phenomena, even without logical or casual connection
Animism
-Tendency to attribute life to non-living objects
