• Humans have a limited capacity to perform tasks
• Dual-task studies applied in the driving domain
• Auditory & cognitive distractions
Background
![Page 3: Comparing performance on a number of auditory memory tasks](https://reader036.fdocuments.in/reader036/viewer/2022062616/5499c976b479594c4d8b575d/html5/thumbnails/3.jpg)
• Cognitively engaging auditory tasks affect driving (e.g. Strayer & Johnston, 2001; Strayer et al. 2003)
• E.g. cognitive tunneling, visual tunneling, reduction in visual span (Victor et al. 2005; Wood et al., 2006; Reimer, 2009)
• Greater task difficulty Greater effect
Background
![Page 4: Comparing performance on a number of auditory memory tasks](https://reader036.fdocuments.in/reader036/viewer/2022062616/5499c976b479594c4d8b575d/html5/thumbnails/4.jpg)
• Cognitive aspect of task is usually manipulated
• Examples: • more difficult sums
(Harbluk et al., 2007)
• storage of more information in memory (Jamson & Merat, 2005)
• manipulation of information e.g. word generation (Strayer & Johnston, 2001)
Background
![Page 5: Comparing performance on a number of auditory memory tasks](https://reader036.fdocuments.in/reader036/viewer/2022062616/5499c976b479594c4d8b575d/html5/thumbnails/5.jpg)
Background
• It’s difficult hearing sound in the car:• In-car acoustics (rear seat passengers,
noisy cabin, little visual information etc.)
• Sensory loss
• So does the difficulty in perceiving the sound source have an effect on task performance?

• Ease of language understanding model (Ronnberg et al., 2008)
Background

• Do small differences in task difficulty result in significant differences in task performance?
• Young, normally hearing participants (n = 25)
• Asked to perform single tasks
• Accuracy & reaction time

• Tone continuous memory task
• Paced auditory serial addition task (Rizzo et al., 2004; Uc et al., 2006): 1 , 4 , 3 , 2 , 1

Study 2
• Three tasks carried forward:• 0-back
• Digit continuous memory task
• Paced auditory serial addition task
• Applied two levels of hearing loss simulation to the stimuli (Moore & Glasberg, 1993; Baer & Moore, 1993)
• Expected that explicit processing required, thus task performance would decrease

Summary
• Small differences in task type chosen can still have an effect on performance
• Need for standardisation/research into this
• Moderate hearing loss has the capacity to make auditory tasks significantly more challenging
• This may have a knock-on effect on driving

Next steps
• Questionnaire study
• Effect of hearing loss on useful field of view
• Dual-task driving simulator study with simulated hearing loss
• Detection response task
