previously known verbal <strong>in</strong>formation but he was unable to learn new verbal<br />

concepts.<br />

These studies although small <strong>in</strong> number <strong>in</strong>dicate that some memory-impaired<br />

people are able to demonstrate learn<strong>in</strong>g (<strong>in</strong> particular those people who have<br />

acquired amnesia through trauma), however, it may not be the case for all<br />

<strong>in</strong>dividuals (<strong>in</strong> particular, people with progressive memory impairments). As<br />

previously discussed, aphasia from a stroke is sudden <strong>in</strong> onset and not<br />

progressive <strong>in</strong> nature (see section 2.2), therefore any acquired memory<br />

impairment could be assumed to be more similar <strong>in</strong> nature to memory<br />

impairment from trauma rather than dementia. F<strong>in</strong>d<strong>in</strong>gs from this population<br />

suggest that this type <strong>of</strong> memory process<strong>in</strong>g difficulty would not prevent new<br />

learn<strong>in</strong>g. The follow<strong>in</strong>g <strong>in</strong>vestigations evaluate the evidence <strong>of</strong> new learn<strong>in</strong>g with<br />

people with aphasia.<br />

2.8.5.3 Adults with aphasia learn<strong>in</strong>g vocabulary<br />

There have been a small number <strong>of</strong> studies evaluat<strong>in</strong>g the ability <strong>of</strong> people with<br />

aphasia to learn new words. Similar to studies with healthy and memory<br />

impaired adults various techniques have been employed to evaluate learn<strong>in</strong>g.<br />

Some <strong>of</strong> these studies have utilised real words that were unfamiliar to the<br />

participants to demonstrate the learn<strong>in</strong>g <strong>of</strong> vocabulary. Grossman and Carey<br />

(1987) report that <strong>in</strong> the 1970s several researchers attempted to teach new<br />

words to people with aphasia but failed to demonstrate any ability on the<br />

participants’ part to acquire new words. Grossman and Carey’s (1987) own<br />

study aimed to evaluate their participants’ knowledge <strong>of</strong> one word (bice) that<br />

was considered to be unknown to them. The results <strong>in</strong>dicated that while many <strong>of</strong><br />

their participants demonstrated some learn<strong>in</strong>g they presented with varied<br />

learn<strong>in</strong>g pr<strong>of</strong>iles, which the authors suggest is synonymous with their <strong>in</strong>dividual<br />

presentation <strong>of</strong> aphasia. They demonstrated that people with Broca’s and fluent<br />

aphasia presented with very different learn<strong>in</strong>g abilities for the new word. Basso<br />
