The Procedural Deficit Hypothesis (PDH) (Ullman & Pierpont, 2005) suggests that individuals with specific language impairment have deficits in procedural memory which result in difficulties with rule-governed processes in language. Lexical processes are less impaired given their reliance on normal declarative memory. According to the Argument Structure Hypothesis (Boland & Blodgett, 2006), processing arguments in sentences is eased by activation of lexical information. Adjuncts are processed by application of syntactic rules. In this study, 23 adults with SLI and 23 typical language peers processed sentences with prepositional phrases that were either arguments or adjuncts. Sentences were presented auditorily using self-paced listening. Noun arguments were processed faster than verb adjuncts, but times were similar across groups. Correlations between co-occurrence frequency and processing times were found for both arguments and adjuncts in adults with SLI, but only for arguments in typical language adults. The data suggest that adults with SLI may compensate with an associative memory process when processing adjuncts.
