Concepts
Understandings used to group together different things (mental folders)
Ex: apples and pears are fruits
Dual Representation
Understanding that one thing can stand for something else (1 object 2 meanings)
Scale Model Task
Kids have to find the same toy in the real version of the home after looking the the model home
(3 yo succeed & 2.5 yo fail)
Picture task
Both 3 yo and 2.5 yo succeed
Enlarging Machine
The kids understood the model room and real room were the same (real experiences stick better)
Young children struggle with…?
Dual representation, not 3D
Scale model behind glass/play
2.5 yo-More successful because less temptation
3 yo- Encouraged to play with model first, so they are more likely to treat them as a toy (less successful)
Video Deficit Effect
Young children struggle to learn from video
Touch Screens
-Touching/swiping make it hard to learn because they get distracted by the action
-But it links child’s action to outcome
Dolls and Abuse
-Children younger than 5 can’t connect between self and doll
Use of manipulatives
Physical objects to teach math like blocks or beads
-Dual representation (objects and symbols)
Habituation/Novelty Method
Showing babies the same thing until they get bored, then showing them something new
Habituation/Novelty Method Conditions
3-4 moth olds
-Cat and dog condition
-Test= one new cat and dog picture
Habituation/Novelty Method Results
Babies who had the cat condition looked at the dog longer and vice versa
Habituation/Novelty Method Conclusion
-Infants are capable of perceptual categorization (group objects based on similar appearances)
-Rely on parts
Category Hierarchies
Organizing categories into levels from broad to specific
Children’s earliest categories are at the…?
medium or basic level
-broad=plant
-medium=tree
-specific=oak
Basic categories have…?
-Consistent characteristics (all dogs have fur)
-Easy to distinguish
-Parents start off basic then go to more specific categories
Numerical Equality
Number objects have something in common (3 blocks and 3 apples share the #3)
Newborns looking…?
Matched # of syllables which means they notice quantity differences
How sensitive are they with number differences?
6 vs. 18-YES
4 vs. 8-NO
-Discrimination becomes more precise during the 1st year
Infant Arithmetic; Violation of Expectation Method
Showing babies something that shouldn’t happen to see if they notice
Babies looked longer at the…?
Impossible event (5 mo)
-babies expect math to make sense
Infants look longer because of the Violation of Object Knowledge
The object disappeared which they know shouldn’t have happened
