Abstract:

A cognitive, text-based test battery, presented as text on a computer screen (TIPS), was used to assess properties of central cognitive processing relevant for visual and audiovisual speech comprehension. TIPS was compared and contrasted with another, purely auditory, battery, ACE, aimed at assessing afferent (A), central (C) and efferent (E) auditory communicative functions. The results show that there is no overlap with the 'A' component, but some overlap between TIPS parameters and the 'C' component, especially when the auditory-language tests are used in the C estimate. However, the TIPS parameters show high correlations with the 'E' component (i.e. measuring output and phonological parameters), suggesting that the efferent component may be composed of an interesting central feature. TIPS parameters do not fare as well in the predictions of the auditory ecological test performances, but the ACE parameters do, especially when organized according to a cognitive complexity parameter. In order to optimize the conceptual and practical benefit of the TIPS and ACE concepts, TIPS needs to be adapted auditorily and ACE tests need to be audiovisual. These developments will become important for ecological audiology.
