  tracker

Habituation

Question 4

Visual Acuity and Color Perception
Visual acuity

Answer 4

measures the sharpness of visual discrimination in infants
* if they can tell the difference between Simple versus complex patterns

Question 5

Contrast sensitivity definition

what is this due to?

Answer 5

infants cant tell a difference between light blue and blue but instead can tell difference ebwteen black and white since they are so different from eachtoher

• Due to cones

Question 6

Cone cells

Answer 6

Infant cant tell the difference between colors that much(Contrast sensitivity ) because of the immarituy of the cone cells

Cone cells are
*Light-sensitive neurons

The immairty of these cones affect infant vision (20/120 birth vision)
cones are not fully developed
