Two studies investigated the effects of errors in German business letters written by Dutch students. Gaining insight into these effects is important since Germany and the Netherlands are one of the largest economically interdependent partnerships. One hundred and fifty-six German professionals rated letters with errors and letters without errors…

Access to definitions facilitates the learning of word meanings when novel words are encountered in reading. However, the memorial costs and benefits of inferring word meanings from context, compared to seeing definitions of unfamiliar words before reading, are not yet well understood. We conducted two experiments with adult L1 (English) and L2…

Our study examines written corrective feedback generated by two online grammar checkers (GCs), Grammarly and Virtual Writing Tutor, and by the grammar checking function of Microsoft Word. We tested the technology on a wide range of grammatical error types from two sources: a set of authentic ESL compositions and a series of simple sentences we…

This study examined the differential effects of systematic perception and production practice and the role of musical ability in learning Mandarin tone-words by native English-speaking adults in a training study. In this study, all participants (N = 38; 19 for each practice group) were first taught declarative knowledge of Mandarin tones and of…

This article extends Optimality Theoretic studies to the research on second language tone phonology. Specifically, this work analyses the acquisition of identical tone sequences in Mandarin Chinese by adult speakers of three non-tonal languages: English, Japanese and Korean. This study finds that the learners prefer not to use identical lexical…

The article introduces learners between two age groups: childhood and adulthood. The aim of the author is to analyse the writing skills of French primary school learners--mostly 14 years old--and to determine which descriptors could be used to assess them. The article begins with a presentation of the learners' characteristics and continues with a…

This article presents a study performed to investigate the role of simulation in second language learning while using a virtual environment. Participants were asked to explore a virtual park while learning 15 new Czech verbs (action verbs that describe movements performed with either the hand or the foot, and abstract verbs). This learning…

The study of language production by adults who are learning a second language (L2) has received a good deal of attention especially when it comes to omission of inflectional morphemes within L2 utterances. Several explanations have been proposed for these inflectional errors. One explanation is that the L2 learner simply does not have the L2…

This study compared negative and positive evidence in adult word learning, predicting that adults would learn more forms following negative evidence. Ninety-two native English speakers (32 men and 60 women [M[subscript age] = 20.38 years, SD = 2.80]), learned nonsense nouns and verbs provided within English frames. Later, participants produced…

This study assessed, in a sample of 98 adult native speakers of Dutch, how their lexical skills and their speaking proficiency varied as a function of their age and level of education and profession (EP). Participants, categorized in terms of their age (18-35, 36-50, and 51-76 years old) and the level of their EP (low versus high), were tested on…

This study examined the development of integrated knowledge or automatic competence in adult SLA. Automatic competence was operationalized in terms of the participants' sensitivity to grammatical errors in a self-paced reading task. Their sensitivity was determined by observing whether there was a delay in reading ungrammatical sentences. Native…

A study of the processing of morphophonology by native speakers and second language learners focused on the processing of the Japanese potential suffix. The subjects were 13 Japanese adults (mean age 27.1) and 13 advanced learners of Japanese as a second language (mean age 26.6). The production of the potential inflection by the two subject groups…

The errors on cloze tests completed by 22 German adults who spoke English and 40 American college students were analyzed to determine whether predictable error patterns occurred. The results indicated predictable error patterns at the independent, instructional, and frustration reading levels for all the adults. The error profiles of the two…

Item responses by adult Egyptian native speakers of Arabic on the ALIGU test battery were analyzed statistically to determine which items deviated significantly from the expected frequency of correct responses, and which item distractors were chosen most frequently. Thirty-two of 100 grammar responses showed significant incorrect responses, and on…

Productive errors in the Spanish of 3 Spanish-speaking children and 115 adults learning Spanish as a second language are analyzed. The errors are organized into three categories--lexical, morphological, and syntactic--and each category is further divided according to the type of cognitive error-processing strategy shown: simplification, reduction…
