| Abstract: |
Examined generalization patterns across wh question forms requiring wh-movement in a single-S multiple baseline experiment with 2 aphasic adults (aged 62-72 yrs). Within question form generalization also was evaluated by examining formulation of untrained sentences of varied complexity, with complexity defined in terms of the number of phrasal nodes in the d-structure representation of sentences. For both Ss, the heuristic strategy was successful in facilitating generalization from more to less complex interrogative sentences. For 1 S, generalization across wh forms was noted. Disrupted grammatical/linguistic processes and representations involved in translating d-structure to s-structure representations may explain some sentence production deficits seen in agrammatism, and support the use of wh-movement treatment for ameliorating this deficit pattern. |
