Language Use with Blissymbolics

Research output: Chapter in Book/Report/Conference proceedingPaper in conference proceeding


Three young adults with cerebral palsy who used Voice Output Communication Aids (VOCAs) with Blissymbolics took part in a study where they tried pre-stored phrases for specific activities. Before and after the study, 1 ½ years apart, they took part in semi-structured interviews where they answered open ended questions about the activity shopping. Analyses of the expressions they constructed with their VOCAs, revealed that the participants used longer utterances and more advanced grammar during the second interview, despite the fact that these skills were not targeted during the study. On the other hand, the pre-stored phrases that the participants were given were not used to the extent that had been expected. When they used the pre-stored phrases, the participants tended to only use phrases that performed functions they already had in their Bliss vocabularies. Features that were lacking in these Bliss vocabularies, but were included among the pre-stored phrases, were words and expressions that could be used for starting and ending conversations, for turn taking, as evaluations and as feedback. Pre-stored expressions that were used functioned as greetings, thanks and answers to yes and no questions.
