Abstract [en]

Aphasiologists developing treatments for anomia should closely align therapy methods with the typological and morphological characteristics of the language in question. The lead author initiated this study to develop more defensible interventions for speakers of Sesotho, a South African language. Prefix-based cueing (our alternative name for initial phoneme cueing that describes these cues in Sesotho-oriented terms) was compared to a novel technique, root-based cueing (RBC). While prefix-based cues are described in the literature, we hypothesized root-based cues would be more appropriate in this context since they were thought to be more consonant with the linguistic parameters of Sesotho. Two speakers with aphasia, who demonstrated significant anomic symptoms, served as participants. We used a multiple-baseline, single case study design. Two 144-item word lists were developed with every item represented by a photograph. Each of the two word lists was associated with one of the two cueing techniques investigated. After baseline measurements were obtained, each participant attended eight facilitation sessions for each cueing condition, resulting in eight data points per condition and participant. For both participants, RBC resulted in greater naming performance than cueing by means of initial phonemes. Our explanation of these results is based on the Interactive Lexical Network model of lexical access; root-based cues may be more effective because they more efficiently constrain the number of lemmas activated after a cue is provided. We argue that a confluence of factors (word-retrieval processes and the character of Sesotho morphosyntax) gave rise to the noted differences in naming facilitation.
