Although the problem of word class has been explored in numerous first language studies, relatively little is known about this process in SLA. The present study measures second language (L2) learners’ knowledge of word class distinctions (e.g., noun vs. adjective) in a variety of syntactic contexts. English-speaking learners of Spanish from third-semester and third-year courses (N = 240) completed a receptive task that presented contrasting forms belonging to the same word family (e.g., feliz “happy” and felicidad “happiness”). The results indicate that learners from both groups are often unable to distinguish among word classes. In particular, learners have significant difficulty in discriminating between adjectives and nouns. Although ambiguous surface morphology contributes to word class confusions, the results suggest that L2 learners do not always recognize derivational suffixes that clearly mark word class. These difficulties are interpreted as stemming from weak syntactic morphological knowledge as well as incomplete knowledge of L2 distributional regularities.

This study examines the nature of the involvement load (Laufer & Hulstijn, 2001) in second language (L2) lexical input processing through reading by considering the effects of the reader-based factors of L2 reading proficiency and background knowledge. The lexical input processing aspects investigated were lexical inferencing (search), attentional allocation during target word (TW) verification (evaluation), TW episodic memory after verification, TW retention, and changes in lexical input processing. This study also addresses the relationships between inferencing and retention as well as the relationships among the various phases of lexical input processing. A questionnaire on self-reported strategy use during the TW verification task was designed to examine motivation and cognitive involvement. A repeated-measures design was used with a cross-sectional sample of 35 adult L2 learners of Spanish. Participants read narratives (one more and one less familiar) that contained nonsense words. They guessed the meanings of the TWs. After reading all of the stories, participants completed an online inference verification task whose goal was to confirm or to correct guesses and to encourage deeper processing of TWs. This was followed by a test of TW episodic memory (yes/no verification) and a strategy questionnaire. Afterward, participants completed two tests that measured receptive retention of meaning. Analyses reveal differential effects of the reader-based variables across the different aspects of lexical input processing and negative changes in lexical input processing due to an interaction between reading proficiency and background knowledge. Results illustrate how reader-based factors also affect learner involvement and lexical input processing.

This article deals with the interlanguage of adult second language (L2) learners acquiring finiteness. Due to the inaccessibility of bound inflectional morphology, learners use free morphology to mark a syntactic relationship as well as person and number features separately from the thematic verb, expressed by a pattern like the man is go. Results from longitudinally collected production data of Turkish learners of Dutch are reported and present evidence for the claim that (a) verb movement and production of inflectional morphology develop separately in various developmental steps and (b) finite forms in nonfinite contexts (and vice versa) are by-products of this development. Moreover, all is-patterns in different Germanic languages can be explained by the application of minimalist theory of verb movement and recent views on morphology. Is-patterns that correspond neither to the first language nor to the L2—a poverty-of-the-stimulus problem—turn out to be possible in other languages of the world and are constrained by Universal Grammar.

This article examines sensitivity to structural parallelism in verb phrase ellipsis constructions in English native speakers as well as in three groups of advanced second language (L2) learners. The results of a set of experiments, based on those of Tanenhaus and Carlson (1990), reveal subtle but reliable differences among the various learner groups. These differences are interpreted as showing that some L2 learners can acquire sensitivity to parallelism in the absence of surface transfer. Furthermore, the results cast doubt on two conventional theoretical claims: that the parallelism effect has a syntactic basis and that it is uniquely linked to instances of surface anaphora (Hankamer & Sag, 1976).
