Those participants who scored the highest used learning strategies including descriptive analogies, linking words to rhyming words, making mnemonic phrases and also linking the name of the creatures to particular mental images. The other participants’ learning strategies included writing names, skills and in some cases drawing images of creatures, spoken repetition of details and some participants stated that they did not have a learning strategy. Participants were grouped into the high scoring group (Group A – PS1, 4, 6, 7 and 10) versus the low scoring group (Group B – PS2, 3, 5 and 9) to ascertain if there was a significant difference between the high scoring participants, who used mnemonic techniques, and the low scoring ones who did not. As PS8 was unable to participate in the second preliminary study she was excluded from these calculations. One-way ANOVA was conducted on the number items learned using learning strategy as a factor with three levels (word forms, word meanings and type of learning technique) (SPSS for Windows, 2003). A significant difference was found between the type of learning strategy used for both word forms – F (2, 9) = 8.288, p
ehearsal taking place prior to the assessment. However, despite no additional rehearsal or consolidation of learning, as well as the training being short and intensive, some of the novel representations were stored in long-term memory and recalled when required (see Table 3.2). The qualitative data recorded that those participants who achieved the higher scores reported that they used mnemonic type strategies as depicted in Table 3.3. Those with the lower scores reported that they employed learning methods such as written copying of details; learning by repetition and others were unable to explain their learning strategy. The stimuli used in this first preliminary study proved to be suitable for training new vocabulary in adults of normal language and cognitive functioning (see Table 3.1). The data from preliminary study one (see section 3.2.3) raised a number of questions that were addressed in preliminary study two (see section 3.3). Firstly, could the lower scoring participants from Group B (PS2, 3, 5 and 9) enhance their learning scores for similar new vocabulary through training in mnemonic learning strategies immediately prior to a training session? If so, it would suggest that it might be useful to teach such strategies to participants with aphasia in the main investigation prior to training, in order to enhance their learning of the novel stimuli. Secondly, as the images, skills and novel names were created and linked by the same person, was it possible that the mnemonic learning techniques, used by Group A (PS1, 4, 6, 7 and 10), were successful due to the influence of some intrinsic link between the stimuli? Or would these techniques be similarly successful if the names, eye colour and skills were randomly assigned to each image? Additionally, preliminary study two anticipated observing the replication of learning performance by participants thus demonstrating reliability of results from preliminary study one. 82
