It was not possible to quantify the benefit of the independent learning experience or the strategies used by participants to rehearse and consolidate their learning. However the amount of time used by participants was recorded and measured against their learning score to ascertain if the length of rehearsal and consolidation time impacted upon the amount of vocabulary learned. It was predicted that those participants who took more time to rehearse and consolidate the new words would learn and remember more new vocabulary than those who used less independent learning time. The hypothesis, ‘independent learning time is correlated positively with the recall of new vocabulary’ was supported both for immediate (r=+.890; p
person with aphasia only ever producing correct responses. Recent findings suggest that while participants strongly preferred errorless learning techniques, being less frustrating and more rewarding than errorful techniques, errorless learning produced equivalent results to errorful learning in the rehabilitation of anomia (Fillingham et al., 2003; Fillingham et al., 2005). However as there appears to be a paucity of research in this area and all participants in the above investigations did not improve to the same extent, further exploration is warranted. This investigation has highlighted the different learning styles of participants in the preliminary, pilot and main investigation which may account for some of the variation in participant outcome. Perhaps further language therapy investigations should take this factor into account where people may gain further functional improvements using methods more suited to their own individual learning styles. 6.3.6 Summary The factors affecting the learning of new vocabulary have been discussed as isolated entities. While the impact of each factor on both the recovery from aphasia and the ability to learn new language representations is considered important, in reality the various factors act in an integrated fashion. There is opportunity for future research to examine how each factor interacts and impacts one on another. A larger study would enable a more powerful investigation of the inter-relatedness of each of the factors and perhaps establish the relative strength of the impact of each individual factor on the recovery of language and new learning, for example whether the impact of depression is greater than the impact of severity of aphasia. 262
