Individuals who have sustained a traumatic brain injury (TBI) comprise a heterogeneous population of individuals along several variables including etiology, experienced symptoms, recovery, and the long-term effects on cognitive abilities. And while deficits are typically associated with the region of localized damage, many individuals with TBI experience difficulties with irritability, increased impulsivity, reduced frustration tolerance, attention to tasks, memory, reasoning and judgment performance, and comprehension of spoken language.
Given the array of difficulties that are often experienced by this clinical population, it is of vital importance to evaluate their ability to comprehend speech in noise. However, the challenge is determining the underlying mechanisms of auditory processing difficulties. Confounding effects of attention and memory further exacerbates this challenge. It is difficult to conclude whether poor performance is the result of poor attentional capacities or whether it is a problem with memory, but often times a case can be made that poor performance is attributed to a combination of these factors.
To successfully understand speech in environments deluged with competing signals, individual must be able to segregate acoustic information of relevance from information of irrelevance, ignore the information that is irrelevant, and continue to encode and process the information that is pertinent to the task. This is by no means an easy skill, because…
