1.  Considerable laboratory research examining whether working memory is useful for explaining differences in the benefits for speech recognition in noise as a function of compression time constants suggests:
  1. Working memory is not useful
  2. Working memory abilities are strong indicators of who will benefit most from slow time constants
  3. Working memory abilities are strong indicators of who will benefit most from fast time constants
  4. Working memory abilities, in conjunction with hearing loss configuration and age, are significant predictors of who will benefit most from fast time constants
2.  In general when comparing the clinically based study presented examining whether working memory is useful for explaining differences in the benefits for speech recognition in noise as a function of compression time constants to previous laboratory work:
  1. The findings were unrelated
  2. The findings in the current clinical study were in surprisingly good agreement to the previous laboratory studies
  3. The findings in the current clinical study were directly in opposition to the previous laboratory studies
  4. None of the above
3.  According to the data presented, one of the least effective microphone strategies for listening in a car is:
  1. Directional microphone hearing aids
  2. FM systems
  3. Omnidirectional hearing aids
  4. Remote microphones
4.  According to the data presented, one of the most effective microphone strategies for listening in a car to when the talker is seated next to you is:
  1. Backwards directional
  2. Signal sharing
  3. Side suppression
  4. Adaptive directional
5.  Although the study design for the study by Wu et al. has strong face validity since recordings were completed in moving vehicles, one limitation this created was:
  1. The researchers had difficulty collecting data while driving
  2. The fluctuating level of noise in the real world limited interpretation of some of the results
  3. The study was not actually real world because few people actually drive in Iowa
  4. The use of 3 different manufacturers invalidated the results
6.  According to Cox et al (2014), by far the factor listeners attributed the most importance to when judging a hearing aid was:
  1. Annoyance with background noise
  2. Overall sound level
  3. Sound quality
  4. Speech recognition
7.  According to Cox et al (2014):
  1. Hearing aids provide little benefit
  2. Hearing aids provide considerable benefit, and more sophisticated hearing aids provide considerably more benefit than their less sophisticated counterparts.
  3. Hearing aids provide considerable benefit, but more and less sophisticated hearing aids provide approximately the same self-perceived benefit.
  4. None of the above
8.  According to the research presented:
  1. Noise reduction provides no significant benefits
  2. Noise reduction programs can reduce listening effort, but only in easier listening situations
  3. Noise reduction programs can reduce listening effort, but only in more difficult listening situations
  4. Noise reduction programs can reduce listening effort, but only for listeners with slower cognitive processing
9.  According to the research presented and considering how listeners find sounds presented in the rear hemisphere:
  1. Listeners switch from a simple orienting movement to a search behavior when using hearing aids with directional microphones
  2. Listeners are faster locating sound sources using hearing aids with directional microphones
  3. Listeners often initially turn the wrong way when fitted with omnidirectional hearing aids
  4. None of the above
10.  According to the research presented that examined conversations during audiology appointments:
  1. Patients generally do not generally bring up psychosocial or emotionally charged issues.
  2. When patients do bring up psychosocial or emotionally charged issues most clinicians provide an empathic response.
  3. Some patients leave the hearing aid selection appointment without deciding whether they want to pursue hearing aids after an escalation in their expression of psychosocial issues which are not addressed by the audiologist.
  4. None of the above
