Exam Preview for 40265: The Relationship Between Listening Effort a

The Relationship Between Listening Effort and the Brain Using Functional Near Infrared Spectroscopy (fNIRS)

Please note: exam questions are subject to change.

1. Which one of these methods would NOT be considered to measure listening effort? Reaction time Physiological measurements Number of words repeated correctly Self-report questionnaire
2. Which of the following is NOT a limitation in fNIRS research? fNIRS signals can be influenced by extracerebral blood flow fNIRS cannot measure deep brain structures Skin pigmentation and hair density can impact fNIRS measures fNIRS signals cannot be measured in total darkness
3. What is the difference between HbO and HbR? HbO measures oxygenated blood coming from the heart whereas HbR measures deoxygenated blood going to the heart HbO measures deoxygenated blood going to the heart whereas HbR oxygenated blood coming from the heart HbO is more elevated under easier listening conditions and HbR is more elevated under more difficult listening conditions HbO measures oxygenated blood used for a specific task whereas HbR measures oxygenated blood that is not used for a specific task
4. In the study, which statement best describes the relationship between the fNIRS results and behavioral results? Listening accuracy did not change between conditions, whereas listening effort and cortical activation increased in more challenging listening conditions Listening accuracy decreased, listening effort increased, and cortical activation increased in more challenging listening conditions Listening accuracy increased, listening effort decreased and cortical activation decreased in more challenging in listening conditions Listening effort did not change between conditions, whereas listening effort decreased and cortical activation increased in more challenging listening conditions
5. In the study, which part of the brain was sensitive to differences in listening conditions? Prefrontal cortex Parietal cortex Occipital lobe Hippocampus
