Question 6

The emergence of self-recognition is sometimes studied using the red dot test in which a red dot is placed on a child's forehead or nose. The child is then placed in front of a mirror. If the child touches his or her nose rather than pointing at the mirror or looking behind it for someone, then self-recognition is inferred. A developmental psychologist conducts the red dot test by using a sample of 15 one-month-old babies. She tests them again at 18 months of age. What type of test was employed?

Accepted Answer

A)  z-test 
B)  one-sample t test 
C)  independent samples t test 
D)  repeated measures t test 
A)  z-test 
B)  one-sample t test 
C)  independent samples t test 
D)  repeated measures t test
