The acquisition of systematic patterns and exceptions in different languages can be readily examined using the causative construction. Persian allows four types of causative structures, including one productive multiword structure (i.e. the light verb construction). In this study, we examine the development of all four structures in Persian child…

A robust result in research on the production of grammatical agreement is that speakers are more likely to produce an erroneous verb with phrases such as "the key to the cabinets", with a singular noun followed by a plural one, than with phrases such as "the keys to the cabinet", where a plural noun is followed by a singular.

Present a study in which Arab subjects were to change 10 English declarative sentences into yes/no questions. Results showed 25.6 percent of the answers were erroneous. An attempt is made to account for the source of error. Most errors were not due to effects of the native language, but to the verb form used. (PJM)

Presents a framework for dealing with errors in natural language sentences within the context of automated second-language teaching. Using a feature grammar, it is possible to describe various types of errors in a uniform framework, clearly define an error, and analyze the error source. (24 references) (Author/CK)

This study explored the dichotomy between global errors, that is, those violating rules of overall sentence structure, and local errors, that is, those violating rules within a particular constituent of a sentence, and the relationship of these to communication breakdown. The focus was tense continuity across clauses (TC) and subject-verb…
