Two experiments were implemented to examine this purpose. Experiment I: Single Word Comprehension Approach (SWCA) established the effectiveness of an intensive treatment protocol on single word auditory comprehension (n = 6). Alternatively, Experiment II: Speech Perception Approach (SPA) examined the outcomes of an intensive treatment protocol on speech perception in individuals with profound global aphasia (n = 2). The researcher employed an ABA single subject design for both experiments, and examined the following variables: (1) changes in single word comprehension (SWCA) or speech perception (SPA); (2) the number of self-initiated requests for repetition and lip-reading cues; (3) the effectiveness of repetition and lip-reading cues; (4) the indirect effects of the protocols on verbal expression (SWCA – naming; SPA – repetition; Both – narrative skills); (5) and generalization to functional communication environments. Results revealed that all participants enrolled in the SWCA or SPA exhibited a lack of awareness regarding their comprehension impairment at the onset of treatment. Despite this reduced awareness, 7 of the 8 demonstrated a large effect on either single word comprehension or speech perception. A generalization effect to untrained stimuli was also exhibited by these participants. The use of repetition successfully improved speech perception and single word comprehension in all participants; however lip-reading was beneficial in only 1 of the 8 participants. An indirect effect on verbal expression naming ability was demonstrated by 5 of the 6 SWCA participants; this effect was not observed in the SPA participants. Carryover of these skills to functional communication situations was reported by one of the eight caregivers. These finding suggest that individuals with severe to profound, deficits have the potential for continued improvements in speech perception or auditory comprehension, even in the chronic stages of recovery. However, caregiver involvement, use of personally relevant stimuli and rehabilitation protocols designed to increase self-awareness of speech perception and single word comprehension impairments may be a crucial link to generalization of communication gains to functional situations with this population. 2012-10-05 English text University of Cincinnati / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=ucin1337288091 http://rave.ohiolink.edu/etdc/view?acc_num=ucin1337288091 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
