when do babies learn words better?
Perceptual constraints
cognitive bias that young children exhibit when learning new words. It refers to the tendency to categorize objects based on their shape.
For example, if a child learns the word “ball,” they may extend that label to other round objects, such as oranges or balloons
Pragmatic constraints
fast mapping, mutual exclusivity, and intentionality and emotional reactions
fast mapping
Rapidly learning a new words because you hear it contrasted with one you know
- e.g., Give me the chromium tray, not the red one (By age 2)
mutual exclusivity
one object has only one label
- if you hear a new label, must be for a new object (18 most or before)
