Most elderly individuals, if asked, are more likely to report complaints within their short term memory. A correlation has been found between sensory status and cognitive functioning (Verhaegen, 2014). It is not a surprise as hearing loss is known to be the thirst common chronic disease in elderly people. Not only can the loss of hearing affect perception of information, it can have diverse effects in physical, emotional, social and behavioural functions as well (Shahidipour, 2013). This can be seen in studies looking at short term memory performance within younger and older subjects, and in doing so determines whether there truly was an age interaction in which the hearing impairment increases as individuals age, leading to declines or impairments in their memory. When looking at groups of subjects of different ages and hearing abilities, it was shown that when controlling for age and relative hearing capabilities, individuals who had supplemented assistance with hearings still performed lower than the two groups (Kurt, 2011; Verhaegen, 2014). Not only does it indicate long term memory impairments can be investigated upon a significant amount of people, but it also suggests that its interactions with other cognitive functions have effects in widespread manners.
When it comes down to short term memory problems, many other factors are attributable such as hearing impairment (Shahidipour, 2013). Studies also found an interaction between hearing impairment and cognitive functions such as memory impairment within the elderly. Despite having hearing aid technological assistance, the individuals had less of an accuracy in speech perception for many words and as a result relied much more on the working memory in order to identify speech
