Morphological variability in second language Spanish

Research on morphological variability in second language (L2) acquisition has focused on the syntactic consequences of variability: that is, whether or not morphological variability entails underlying syntactic deficits. The interrelationship between morphological features in their own right has been largely ignored. This thesis addresses the representation of L2 features by investigating the use of default morphology---the outcome of systematic substitution errors employed by speakers of L2 Spanish. It is hypothesized that underspecified features act as defaults; by assumption, those features that are unmarked are underspecified. / Evidence to support this hypothesis comes from two sets of experiments conducted on intermediate- and advanced-proficiency L2 Spanish subjects (L1 English). The first set of experiments addresses verbal morphology, and consists of a spontaneous production experiment on person, number, tense, and finiteness, and a comprehension task on person and number. The second set of experiments addresses gender and number in nominal morphology, and consists of a spontaneous production experiment on determiners, an elicited production experiment on clitics and adjectives, and a picture-selection task on the comprehension of clitics. Across tasks and across verbal and nominal domains, errors involve the systematic substitution of underspecified morphology. The observation that morphological variability extends to comprehension, and is qualitatively similar to the variability found in production, counters the suggestion that variability is strictly a product of mere performance limitations on production. Finally, the systematicity of substitution errors suggests that the natural classes of features such as gender, number, tense, and person are acquirable in an L2, regardless of whether or not these features have been instantiated in the native language.
