Answer 21

2 months old

Question 22

what is size constancy (Slater et al., 1990)

Answer 22

the ability to perceive an object as having the same size even when the image of that object on the retina changes due to the objects distance from us

Question 23

findings of Slater et al size constancy

Answer 23

infants even around 4 months old showed evidence of size constancy

Question 24

what is sshape constancy (Caron et al., 1979)

Answer 24

the ability to perceive an object as having the same shape, even when viewed at different angles

findings of caron shape constancy

Answer 25

infants as young as 4 months were able to demonstrate shape constancy

checkerboard under glass

shallow and deep sides

if babies perceive depth they should be unwilling to crawl over
