Answer

Brief Explanations:

  • For the first question:
    • In signal - detection theory:
      • A “miss” is when a signal is present but not detected. Here, the actual criminal (signal) is not in the lineup, so this is not a miss.
      • A “correct rejection” is when a signal is not present and it is correctly identified as not present. But the witness wrongly identified someone, so this is not a correct rejection.
      • A “hit” is when a signal is present and detected. Since the actual criminal (signal) is not in the lineup, this is not a hit.
      • A “false alarm” is when a signal is not present but is detected. In the police lineup, the actual criminal (signal) is not there, but the witness “detected” (pointed to) someone. So, this is a false alarm.
  • For the second question:
    • The auditory pathway:
      • Sound enters the ear. Then, the cochlear nucleus (part of the brainstem that first receives auditory input from the cochlea) is activated. After that, the medial geniculate nucleus (a thalamic nucleus that relays auditory information) is involved. Finally, the primary auditory cortex (where auditory perception occurs) is activated.

Answer:

  • First question: C. false alarm
  • Second question: Ear → cochlear nucleus → medial geniculate nucleus → primary auditory cortex
