a b s t r a c tNative speakers of Dutch do not always adhere to prescriptive grammar rules in their daily speech. These grammatical norm violations can elicit emotional reactions in language purists, mostly high-educated people, who claim that for them these constructions are truly ungrammatical. However, linguists generally assume that grammatical norm violations are in fact truly grammatical, especially when they occur frequently in a language. In an fMRI study we investigated the processing of grammatical norm violations in the brains of language purists, and compared them with truly grammatical and truly ungrammatical sentences. Grammatical norm violations were found to be unique in that their processing resembled not only the processing of truly grammatical sentences (in left medial Superior Frontal Gyrus and Angular Gyrus), but also that of truly ungrammatical sentences (in Inferior Frontal Gyrus), despite what theories of grammar would usually lead us to believe.

Dutch prescriptive grammar rules dictate that the complementizer dan 'than' should be used in comparative constructions of inequality. This has been an issue for grammarians from the sixteenth century onwards when als 'as' started to be used as an alternative form in this type of context. In order to find out why and when people choose one comparative marker over the other, we examined the use of these markers in the Spoken Dutch Corpus (CGN). We found that the use of dan is overall more common than als in comparative constructions of inequality, even though from a linguistic point of view als might be favoured. The choice between als and dan turns out to be strongly correlated with the level of education. Although this factor has been assumed to be of influence for a long time, as far as we know it has never been quantitatively tested before. We conclude that the effect of the level of education we found reflects the strong influence of the prescriptive rule taught in schools, repressing the use of als in comparatives of inequality.

The processing of idiomatic expressions is a topical issue in empirical research. Various factors have been found to influence idiom processing, such as idiom familiarity and idiom transparency. Information on these variables is usually obtained through norming studies. Studies investigating the effect of various properties on idiom processing have led to ambiguous results. This may be due to the variability of operationalizations of the idiom properties across norming studies, which in turn may affect the reliability of the subjective judgements. However, not all studies that collected normative data on idiomatic expressions investigated their reliability, and studies that did address the reliability of subjective ratings used various measures and produced mixed results. In this study, we investigated the reliability of subjective judgements, the relation between subjective and objective idiom frequency, and the impact of these dimensions on the participants’ idiom knowledge by collecting normative data of five subjective idiom properties (Frequency of Exposure, Meaning Familiarity, Frequency of Usage, Transparency, and Imageability) from 390 native speakers and objective corpus frequency for 374 Dutch idiomatic expressions. For reliability, we compared measures calculated in previous studies, with the D-coefficient, a metric taken from Generalizability Theory. High reliability was found for all subjective dimensions. One reliability metric, Krippendorff’s alpha, generally produced lower values, while similar values were obtained for three other measures (Cronbach’s alpha, Intraclass Correlation Coefficient, and the D-coefficient). Advantages of the D-coefficient are that it can be applied to unbalanced research designs, and to estimate the minimum number of raters required to obtain reliable ratings. Slightly higher coefficients were observed for so-called experience-based dimensions (Frequency of Exposure, Meaning Familiarity, and Frequency of Usage) than for content-based dimensions (Transparency and Imageability). In addition, fewer raters were required to obtain reliable ratings for the experience-based dimensions. Subjective and objective frequency appeared to be poorly correlated, while all subjective idiom properties and objective frequency turned out to affect idiom knowledge. Meaning Familiarity, Subjective and Objective Frequency of Exposure, Frequency of Usage, and Transparency positively contributed to idiom knowledge, while a negative effect was found for Imageability. We discuss these relationships in more detail, and give methodological recommendations with respect to the procedures and the measure to calculate reliability.

Idiomatic expressions like hit the road or turn the tables are known to be problematic for L2 learners, but research indicates that learning L2 idiomatic language is important. Relatively few studies, most of them focusing on English idioms, have investigated how L2 idioms are actually acquired and how this process is affected by important idiom properties like transparency (the degree to which the figurative meaning of an idiom can be inferred from its literal analysis) and cross-language overlap (the degree to which L2 idioms correspond to L1 idioms). The present study employed a specially designed CALL system to investigate the effects of intensity of practice and the reading modality on learning Dutch L2 idioms, as well as the impact of idiom transparency and cross-language overlap. The results show that CALL practice with a focus on meaning and form is effective for learning L2 idioms and that the degree of practice needed depends on the properties of the idioms. L2 learners can achieve or even exceed native-like performance. Practicing reading idioms aloud does not lead to significantly higher performance than reading idioms silently.These findings have theoretical implications as they show that differences between native speakers and L2 learners are due to differences in exposure, rather than to different underlying acquisition mechanisms. For teaching practice, this study indicates that a properly designed CALL system is an effective and an ecologically sound environment for learning L2 idioms, a generally unattended area in L2 classes, and that teaching priorities should be based on degree of transparency and cross-language overlap of L2 idioms.

Learning to read is a prerequisite to participate in our knowledge society. Developing reading skills requires intensive practice with individual evaluation and guidance by teachers, which is not always feasible in traditional classroom instruction. Automatic Speech Recognition (ASR) technology could offer a solution, but so far it has been mostly used to follow children while reading and to provide correct word forms through text-to-speech technology. However, ASR could possibly be employed at earlier stages of learning to read when children are still in the process of developing decoding skills. Early evaluation through ASR and individualized feedback could help achieve more personalized and possibly more effective guidance, thus preventing reading problems and improving the process of reading development.In this paper we report on an explorative study in which an ASR-based system equipped with logging capabilities was developed and employed to evaluate decoding skills in Dutch first graders reading aloud, and to provide them with detailed, individualized feedback. The results indicate that ASR-based feedback leads to improved reading accuracy and speed and that the log-files provide useful information to enhance practice and feedback, thus paving the way for more personalized, technology-enriched approaches to reading instruction.
