Mom Billie and dad Bob are discussing the abilities of their two-month-old son Thorton. Billie claims that Thorton can recognize both of his parent's voices. Bob says that Thorton cannot recognize either voice. If Thorton is a typical two-month-old, then who is correct?
 
  a. Billie
  b. Bob
  c. Neither, as Thorton can likely recognize Billie's voice but not Bob's voice
  d. Neither, as Thorton can likely recognize Bob's voice but not Billie's voice

Question 2

Within days of their baby's birth, Ben and Jen are having an argument about their son. Jen claims that he recognizes her voice, but Ben says that this is impossible. Knowing the research in this area, you are able to tell them that
 
  a. Ben is correct (voice recognition does not occur until around six months of age).
  b. both could be correct, as babies can recognize only the first voice that they heard immediately following delivery (if this was Jen's voice, then she is correct; if it was not Jen's voice, then Ben is correct).
  c. Jen is correct (maternal voice recognition is evident a few days after birth).
  d. we do not know who is correct because infants this young cannot be accurately tested.
